Engine And Engine Cooling Problems of Kia Motor Telluride - part 1

The car shuts down and displays the same message a lot of the other complaints are saying. Engine shut off, please put in p or n and restart engine. It shuts down while driving! I have 2 kids under [xxx] and I bought this for safety. It seems kia is aware of this issue and none of the dealerships across the u. S. Have a fix for it yet. And they keep sending the vehicles back out on the roads since they can’t fix it! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Engine shut off while idling. Had to shift into park and restart engine.

2025 kia Telluride engine shut down on highway in construction zone with no shoulder. Engine shut off, alarms sounded and it displayed to put the vehicle in park or neutral and restart. I had to coast to an exit ramp. Vehicle did restart and seems to be intermittent.

I am reporting a potential safety defect involving excessive engine oil loss and persistent oil leakage on my 2020 kia Telluride, VIN [xxx]. The vehicle currently has approximately 100,367 miles. It has been experiencing significant oil loss, approximately one quart of engine oil per week. I am concerned that this amount of oil loss is abnormal and creates a potential safety hazard if the engine loses sufficient oil while the vehicle is being driven. The vehicle has also had repeated oil leaks, including an oil pan leak and timing cover leak. I have taken the vehicle to kia for repairs multiple times, but the oil-related problems have continued. This has required me to continually monitor and add engine oil to prevent the oil level from becoming dangerously low. I specifically brought the vehicle to kia because of the excessive oil consumption and ongoing leaks. However, the dealership has told me that they will not perform an oil-consumption test until the existing oil leaks are repaired. Kia customer care also opened case #[xxx], but I was subsequently told that kia could not provide assistance because the vehicle is outside the standard warranty period. I am concerned that the underlying cause of the excessive oil loss has not been properly diagnosed. I am also concerned about the possibility of engine damage or engine failure if the vehicle continues losing oil at this rate. Kia has also issued a 2026 warranty extension concerning an engine oil-filter-housing gasket leak on certain 2020–2025 Telluride vehicles. I have asked kia to determine whether my vehicle is affected by this condition and whether the current oil leaks are related, but I have not received a satisfactory resolution. I am asking NHTSA to review this complaint along with other complaints involving 2020 kia Tellurides experiencing excessive oil consumption and/or recurring engine oil leaks to determine whether there is a potential safety defect or broader pattern that warrant information redacted pursuant to the freedom of information ac.

Vehicle is shutting down while driving or idling.

On September 24th, 2026, while traveling with my family in my 2020, kia, Telluride, the vehicle began experiencing an unusual engine vibration approximately 200 miles into our trip. About five miles later, I exited the freeway and stopped to inspect it. Once stopped, the engine began knocking loudly. I checked the engine oil and coolant levels; both appeared normal, and the temperature gauge was at its usual reading. After waiting about five minutes, I restarted the vehicle, but the knocking became worse with each start. I stopped running the engine and had the vehicle towed to a kia service center. The vehicle had approximately 99,350 miles. The shop has described the engine problem as a “catastrophic failure. ” the cause and specific failed components are cannot be identified in this kind of failure. This sudden failure during freeway travel with my family created a serious safety concern and I am sure this needs to notified so that it doesn't happen to anyone who own's the same car. There are particles of metal shavings found in oil filter which concludes engine failure with no explanation. Only option I am given is get the engine swap which is ~70% of the total cost of the car. Kia support just says since the car is out of warranty they cannot do anything about it. This is a serious durability issue. I totally understand that the car warranty was reduced for the 2nd owner, but first user could also get this problem on the freeway and can be dangerous for everyone driving in the car as I am still under 100,000miles. I am trying to spread awareness, kia already acknowledges that consuming 1qtz of oil every 1000 miles is normal, which means the engine has a issue that Hyundai/kia needs to fix before more family starts facing this with even worse situation than ours. Please look into this so that they can acknowledge fix the problem and opens a recall for fixing it.

I was attempting to accelerate on the freeway and the rpms kept going up but it felt like the engine didn't want to shift gears. Suddenly the rpms shot all the way up and then dropped to nothing and I was forced to coast off the freeway, thankfully we were by an exit. The vehicle had zero power and we were unable to move it off the road, despite assistance from passersby. The wheels were locked in place and would not move until the tow truck driver showed up and looked something up online to manually force the car into neutral. (though it was displayed as being in neutral) this is a 2021 vehicle bought brand new and has been properly maintained. Approximately 2-3 weeks before this, my husband randomly checked the oil and it was about 2qts low. It was filled and seemed to be running perfectly fine so we didn't give it another thought until this happened but now we're wondering if this particular engine is prone to the excessive oil consumption that has been noted in several other Kia Motors.

Unfortunately, beginning in June 2025, I experienced a serious engine problem. While driving, the vehicle began sputtering and stalled twice in traffic. I immediately brought it to the dealer, where I was told the engine had no oil, despite no prior warning of abnormal oil loss (no engine warning lights and no leaks). The service department added oil and initiated an oil consumption test. On October 4, 2025, the same problem occurred again. While driving, the Telluride began sputtering again, and the dealer again determined that the engine had no oil. I was charged for another oil change and instructed to complete another oil consumption test. During this process, the maintenance supervisor acknowledged that excessive oil consumption was a known and serious issue affecting kia Tellurides and other models, and explained that engine replacement was the appropriate solution. I also observed another Telluride at the dealership undergoing the same type of engine repair. After completing the required testing, the dealer ultimately installed a rebuilt engine in my vehicle to address the excessive oil consumption problem with the original engine. I am now back in the same situation. On September 8, 2026, less than one year after the rebuilt engine was installed, my Telluride once again began sputtering while I was driving. I brought the vehicle to back to the dealer on on September 9, 2026. The service personnel again told me there was no oil in the vehicle, despite it being well within its recommended oil-change interval. More importantly, I was informed that the rebuilt engine currently installed in my vehicle is suspected of having the same excessive oil-consumption problem as the original engine. After following the instructions on yet another engine recheck and oil consumption test, I 've been told that the engine is burning oil at an exponential rate.

I am the original owner of a 2020 kia Telluride that was purchased new in December 2019 and currently has approximately 98,000 miles. The vehicle has been routinely serviced, including regular maintenance performed through authorized kia dealerships. Recently, the vehicle developed a serious apparent engine problem. An independent repair facility inspected the engine oil and found it was very low and visible metallic particles/shavings in the oil. The oil also appeared abnormally burned. The repair facility found no evidence of an external oil leak and advised that the vehicle should not be driven because of the condition of the engine oil and presence of metal. I had the vehicle towed to an authorized kia dealership rather than continue operating it. There were no engine or warning lights indicating low oil. The vehicle is currently awaiting diagnosis by kia under the 10-year/100,000-mile powertrain warranty. I am concerned that the presence of metal in the engine oil indicates an internal engine component failure that could result in sudden engine seizure, loss of propulsion, or other engine failure while the vehicle is being operated in traffic. There was no crash, fire, or injury associated with my vehicle at the time the problem was discovered because I stopped operating it after being advised not to drive it. The vehicle also has significant premature paint delamination on the roof. Large areas of the original factory paint have separated/flaked away from the roof despite the vehicle being approximately six years old. This is not isolated rock chipping or normal cosmetic wear; it appears to be a widespread failure of paint adhesion. I am concerned about additional paint separating from the vehicle while traveling at highway speeds and potentially becoming airborne, as well as the long-term effect of exposed roof metal and corrosion. Kia has been notified of the paint condition but has declined to repair it.

Vehicle was sitting all night and entered the garage in the morning and found the radiator fan at full speed. Car was not running, so backed it out, turned it off and the fan turned back on. Took it to a kia dealer and kept it for a few days and just stated they couldn't duplicate the issue, although I couldn't get them to tell me technically what they checked. I kept the car parked outside for fear there might be an electrical issue and something overheats. Then was recently out and came out to my vehicle to find the fan running again. This time took multiple videos and it now consistently doing it. Took it home for the evening and disconnected the battery, and in the morning as soon as I reconnected the battery the fan started up to full speed again. Dropped it off to another kia dealership and it was still doing it and showed it to the service advisor and gave him the videos. They are currently looking at it now. Also, there were never any warning lights or alarms that anything was wrong. There are so many postings out there on this issue on forums, fb, Telluride sites, etc. , that I'm shocked there isn't at least a kia TSB on this problem.

The engine randomly turns off and I get a warning that says "engine off! shift to p or n, then start engine" this happened recently as my mother in law was making a left hand turn on a busy intersection. If there were other cars coming she would've been hit. There are no prior warnings or indications that the car is having any issues. The car has been inspected by the dealership, which has been unable to reproduce the issue.

My 2025 kia Telluride has experienced repeated, unresolved engine stalling/shutdown while driving. The defect began as stalling at low speeds approaching stops and has escalated to the vehicle shutting off completely while traveling at 45–50 miles per hour on public roads. When the engine shuts off at highway speeds, power steering and power brakes are lost, creating an immediate life-threatening situation for the driver and any passengers. The dealership has made multiple repair attempts across two separate phases of this defect without success. Despite the ongoing safety hazard, the dealer has pressured me to return my rental vehicle and accept the car back without verified resolution of the stalling issue. Kia America customer service has been unresponsive to the urgency of this situation. The vehicle remains unrepaired and unsafe for highway operation. I am requesting that NHTSA investigate this defect, review whether a safety recall is warranted, and add this complaint to the record for the 2025 kia Telluride VIN [xxx]. I am aware that other 2025 Telluride owners have reported similar stalling and unexpected shutdown issues to NHTSA. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I purchased my 2021 kia Telluride s new, with only 22 miles from the test drive. Xxx (approx. 53,000 miles, vehicle age 18 months): the transmission failed while I was traveling approx. 75-80 mph on a major highway in [xxx]. Upon failure, the vehicle suddenly lurched as if the brakes had locked or the parking brake had been applied, nearly causing us to strike our heads on the dashboard and creating a hazardous situation for other traffic. After the failure, the vehicle would only operate in approx. First through third gears and reverse, and would not exceed 25 mph. We were forced to limp the vehicle off a busy six-lane highway. Xxx: due to parts delays, the vehicle was not returned until November 2022 after the transmission work. Xxx (approx. Four months later): the vehicle developed engine knock and excessive oil consumption. Advised this may have been related to oil degradation while the vehicle sat waiting for parts. Since then, I had to regularly check and add oil between oil changes. Despite low oil levels, no oil pressure warning light ever appeared. Xxx (exact date unknown): while opening the sunroof at a stop, a loud crack occurred and pieces of the sunroof track, plastic and metal, fell onto me and my passenger. The glass is intact but became partially stuck open without the track to guide it. Xxx: the engine knock worsened and became a squeal while driving approx. 60 mph. The vehicle lost power, requiring me to turn on hazards and coast off to avoid accident. Dealership mechanic advised that the engine had thrown a rod and blown the oil filter housing gasket. The vehicle is currently at the dealership and available for inspection. Kia has denied coverage despite the failure of a component linked to excessive oil loss and a recently extended 180,000-mile warranty, even after the engine threw a rod following a sudden loss of oil pressure. The failed transmission has likely already been disposed of. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Nhtsa vehicle safety complaint – 2021 kia Telluride I am the original owner of a 2021 kia Telluride with approximately 78,000 miles. My vehicle has experienced recurring mechanical and drivability concerns, including an intermittent check-engine light, a previously reported camshaft-related diagnostic trouble code, and hesitation during acceleration. Of particular concern, there have been instances when I have pressed the accelerator pedal and the vehicle has hesitated before responding. This delayed acceleration creates a potential safety concern, particularly when entering traffic, merging, or navigating intersections where predictable engine response is essential. Additionally, the vehicle has exhibited rough operation while reversing and unusually harsh engine behavior when the automatic engine stop-start system engages. Despite multiple visits to a kia-authorized dealership, including a monitored 1,000-mile oil consumption test, these concerns remain unresolved. The dealership advised that the vehicle passed the oil consumption test but subsequently recommended a dynamic engine cleaning procedure. I was informed that the technician was approximately 85% confident this procedure would resolve the issue. However, no definitive explanation of the underlying mechanical problem was provided. I have requested written documentation of the diagnostic findings and the basis for the recommended procedure. I have also opened a formal case with kia America consumer affairs regarding these unresolved concerns. I am submitting this complaint because I am concerned that the recurring acceleration hesitation and related engine symptoms may indicate a safety-related defect that has not been adequately identified or resolved. I respectfully request that NHTSA document these concerns and evaluate whether similar complaints involving 2021 kia Telluride vehicles indicate a broader safety issue.

The contact owns a 2025 kia Telluride. The contact stated that while driving uphill at 55 mph and depressing the accelerator pedal, the vehicle lost power. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The contact stated that the failure had occurred on several occasions. The approximate failure mileage was 22,000.

I purchased this new vehicle in March of 2026. The vehicle has 6,800 miles. While idle, I started to get a warning the engine was overheating with the ac only blowing hot air while the engine smelt like it was overheating. This put me at risk of being stranded in the heat with my toddler and new born or the vehicle malfunctioning in the highway.

I have a kia Telluride 2020 ex awd automatic. I bought it used about 2. 5 years ago. It’s been having some ongoing issues with oil consumption, which from what I have learned is pretty common in this car. Since I learned that I’ve been increasing the frequency of oil changes and topping off oil in between. It burns oil at an absurd rate, and gives no warning when oil is low. On the most recent change, ~a month ago, the mechanic recommended changing it after 3,000 miles. Yesterday the car completely shut down while driving on the highway, no warning or anything, just a noise, smoke and then the car died in a matter of seconds. I nearly got in an accident trying to drift to the side of the road with no power or anything. No control of the car. Ended up stuck in traffic going 70+ mph with a toddler. After it was towed, our mechanic found there was no oil left and we had two holes in the engine casing. He explained it looks like when the oil ran out completely, some part broke off in the engine and shot through the housing. So it’s looking like we need a new engine. We had not driven it 3000 miles since the last oil change just a month ago, and we have even topped off the oil since that change, most recently a week ago. This means the car burned through about 9 quarts of oil in <3000 miles. Multiple mechanics have told us this is a known issue with the car, and there is nothing to do to prevent it. When we called the dealership to inquire about getting a new engine, they told us we would need to do an oil consumption test. Obviously this is impossible on a car that does not drive and has two holes in the engine. So we are stuck paying out of pocket. Kia is well aware of this issue and is doing nothing.

On September 4, 2026, my son was driving our 2021 kia Telluride on the highway at approximately 70 mph with cruise control engaged when the vehicle suddenly began making a clicking noise, followed by a catastrophic engine failure. We observed no oil-pressure warning or other advance dashboard warning before the failure. The sudden failure at highway speed created a significant safety risk. I am the original owner. The vehicle had approximately 115,000 miles at the time of failure. Its most recent oil change was performed on June 4, 2026, at 112,613 miles, approximately 2,400 miles before the incident. The servicing kia dealership reported that the engine had a hole in it and essentially no oil remaining. The oil filter and drain plug were in place, and the dealership reported no external oil leak that explained the missing oil. An oil-filter-housing leak had previously been repaired in January 2026. The cause of the oil loss and engine failure has not been conclusively established. I am concerned about possible excessive internal oil consumption and the absence of an advance warning before catastrophic failure. I request that NHTSA investigate whether this condition affects other Tellurides and creates a risk of sudden engine failure or loss of propulsion at highway speed. Kia denied my initial request for goodwill repair assistance. The case has been escalated, but remains unresolved. The vehicle and failed engine are available for inspection through the servicing dealership.

There have been two individual episodes of this occurring. While actively driving the entire vehicle shuts off and begins to coast and will not respond to pressing the accelerator. This happened once in our driveway in March. This happened again about 3 weeks ago while driving on the interstate and had to cross multiple lanes of traffic in order to make it to the shoulder. Very unsafe situation with no warning.

We purchased a new 2025 kia Telluride 17 days ago. Just three days after purchasing the vehicle, I experienced a serious and potentially dangerous failure while driving in heavy traffic in downtown chicago. The dashboard suddenly lit up, an alarm began sounding, and the following warning appeared: “engine off! shift to p or n and then start engine. ” I was forced to pull off the road in very congested downtown traffic, put the vehicle in park, turn it off, and restart it. I immediately contacted the dealership. The next day, I took the vehicle to the dealership for an unrelated detailing issue and asked them to check out the car to address what had happened. I was told it was likely a computer fluke and that I would need to wait to see if it happens again. The next day, the exact same thing happened while merging onto the interstate on a tight onramp in congested traffic. This time, I had significant difficulty getting safely to the side of the road and came extremely close to being struck by another vehicle. Again, I had to put the vehicle in park, turn it off, and restart it. The following day, I returned the Telluride to the dealership. It has been there for over a week. They seem to know this is a common issue with Tellurides but they've indicated that kia has not provided guidance on addressing this specific issue. As a result, they could only respond to the code that was generated- which indicates an electrical control issue. I've contacted kia and I'm waiting to hear if they can provide a fix that can guarantee I'm not put into another dangerous situation. If an older person or teenager had been in the situations I had been in, I can nearly guarantee there would've been a very serious and potentially fatal accident. Please help us address this issue!.

The engine just quit when making a brake stop. The rpm went to zero. The car did restart but failed a second time after a few feet of travel and the brakes were applied. There are at least two occasions when the issue occurred within the past two days.

Xxx while returning home, we were crossing a 2 lane bridge between [xxx] and [xxx] heading south, an audible alarm sounded which surprised us and then a message appeared that stated "engine off! shift to p or n, then start engine". Once I was able to refocus my attention to the road, I was then able to turn on my hazard signals, stop the car, shift to park and restart the car. This all happened with traffic behind us and passing us in the opposite lane. There was no shoulder for us to use to get out of the way. I should also mention we were traveling a slight incline up as we were crossing the bridge. This was the second time this has happened and again it forced my attention away from the road so that I could address this issue. Fortunately, this all occurred at low speed, approx 30-35mph. Also, luckily I was able to get my hazard signals on quickly to avoid being rear ended by the sudden occurrence of this issue. I cannot imagine what would have happened if I had been on the interstate going 70+ mph. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Xxx while returning home, we just turned right onto [xxx] heading south, an audible alarm sounded which surprised us and then a message appeared that stated "engine off! shift to [xxx], then start engine". This same problem had just occurred not 10 minutes earlier while crossing the bridge into [xxx] from [xxx]! again, once I was able to refocus my attention to the road, I was then able to turn on my hazard signals, stop the car (no power brakes), shift to park and restart the car. With this occurrence we were fortunate there was no traffic on the street at the time. We were traveling at about 30mph. This was the 3rd occurrence of this problem within 30 days and then again the second occurrence within 10 minutes on the same day! this is really unnerving to have your engine turn off suddenly and without any warnings! just a sudden audible alarm, followed by a message, completely out of the blue! I cannot imagine what will happen should this occur at higher speeds? or in heavier traffic? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Loss of oil that is going out the heads and exhaust. This causes loss of power. Oil light doesn’t come on. This happened twice. Once in March and we took it to the dealership to have it fixed. Unfortunately, the issue wasn’t fixed and it happened again in August.

My 2021 kia Telluride has developed progressively worsening engine problems without any warning lights ever appearing that may present a serious safety concern. Approximately two months ago, the vehicle began experiencing significant engine shaking and rocking. Maintenance and repairs were performed, and the symptoms temporarily improved. The engine symptoms later returned. The vehicle began making a noticeable ticking noise that progressively became much louder and occurred both while idling and during acceleration. The vehicle subsequently shut off after being driven to an independent mechanic. Multiple warning/diagnostic alerts appeared, and the vehicle would not remain running when restarted. The mechanic checked the engine oil and found it essentially empty. Approximately 4½ quarts of oil were added. The ticking noise continued despite the addition of oil. Later that same day, the engine developed a pronounced knocking noise that continued while driving. There was also a hot smell, and I had noticed discolored smoke coming from the exhaust. The vehicle is currently parked and is available for inspection. I have stopped driving it because I am concerned about an engine failure and the possibility of the vehicle shutting off or losing power while being operated. The vehicle has been maintained and I have documentation of its maintenance and repair history. The underlying cause of the severe oil loss and engine symptoms has not been determined.

When driving, the vehicle will randomly shut off. Every warning light and alarm goes off. A message displays on the dash to put the vehicle on p or n to turn it back on. This happens unexpectedly. It's happened about 16 times on the road and 2 times on the highway. This is a huge safety issue. We notified kia in February of 2026, it's gone to the service department three times for this specific issue, but they are unable to recreate it and no codes are stored for them to see what it is. We have recorded the vehicle acting up once it's shut off. This is very dangerous that a new vehicle randomly shuts off, and no one knows what is causing it. Now, it's at the shop for the fourth time. This time the kia engineers have asked the service shop to replace the engine harness along with some sensors and send it to them. We have recordings from kia corporate stating they dont know what it is. We even have a service tech stating that there are others with this issue but no solution has been uncovered.

This started may 8th and is still going on. Engine randomly shuts down while driving. Vehicle alarms and message says engine off shift to p or n then start engine. No warning, happens about once a week. Very scary when in traffic and I cannot move because my engine randomly shuts down. The dealership has had it 3 different times totaling 6 weeks and 5 days and cannot duplicate it.

The car has stalled numerous times on the roadway while driving. The issue has been identified as an oil consumption issue. There was no low pressure warning light or other warning indicating that there is an oil pressure issue or any other early warning of an engine stall. The dealer has indicated that a complete engine replacement is required to correct the problem. Based upon research, there has been a significant amount of complaints pertaining to this issue. This same oil consumption and engine stall issue was part of a class action settlement by kia, however this particular kia model was not covered in the litigation.

2025 kia Telluride, rental vehicle, 29,450 miles at failure. Driving xxx w toward the [xxx] exit with my wife and two children (ages [xxx] and [xxx]), the cluster lit with simultaneous failures: electric power steering, electronic parking brake, abs, stability control disabled, tire pressure monitoring, forward collision-avoidance, lane keeping, master warning. I photographed it. Nothing about how the vehicle drove had changed. At highway speed traveling straight, steering effort felt normal. There was no progressive degradation and no warning I could feel. I noticed a slight difference changing lanes for the exit. On the ramp itself, a banked turn taken at speed, the wheel required extreme force to turn. The loss of assist was undetectable until significant steering input was actually required, which happened mid-maneuver on an interstate ramp. I am a large, physically strong adult and forced the wheel through the turn. I do not believe a smaller, older, or weaker driver could have completed it, and a crash at that interchange seems a likely outcome for many drivers. Stopping on an interstate shoulder with two young children seemed more dangerous than continuing two miles to the airport exit, so I continued, with abs and stability control also inoperative. The vehicle developed harsh, jerky shifting and audible clunking. In the rental return lot the wheel would not turn far enough to complete a tight turn. I shifted to reverse; the vehicle did not move, then shut down completely and would not restart. With the vehicle dead the front doors opened, but the rear doors and liftgate would not, and the windows were inoperable. My children were confined inside roughly 10-15 minutes at 86f until an employee climbed in from the front and released the rear doors from inside. The inability to open rear doors or the liftgate from outside after a total power loss is a serious defect in its own right. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle is burning a significant amount of oil leading to it becoming dry. I am seeing a lot of people complaining about this issue but there has not been a recall sent out.

Over the course of two days, the engine stalled when decelerating at intersections three different times. The engine died with warning lights on the dash and a message: “ engine off! shift to p or n then start engine. ” I had to completely stop, shift gears, and then restart the engine, then back to drive. This happened at or near intersections, creating a significant hazard for myself and others around. Dealer has not been able to identify or replicate the issue. I have safety concerns about driving the vehicle. The third time happened without auto hold or auto start/stop on.

I am reporting a safety concern involving my 2022 kia Telluride ex with approximately 95,000 miles. The vehicle has experienced intermittent rough running, significant loss of engine power, stalling, and recurring check-engine warnings. During one incident, the vehicle started, sputtered, and shut off. The engine oil level was found to be extremely low despite the vehicle having received an oil change approximately 2,000 miles earlier. After adding approximately one quart of oil, the vehicle was able to start and remain running. The check-engine light subsequently illuminated and kia connect reported diagnostic code p000a00. The warning light has intermittently turned off, but the fault remained stored in the vehicle's computer and was later confirmed by a kia dealership. I brought the vehicle to an authorized kia dealership because of the oil loss and drivability concerns. The dealership documented that no external oil leak was found and stated that the engine was likely consuming excessive oil. An oil-consumption test was initiated. According to the dealership's subsequent documentation, after approximately 1,000 miles the engine was more than two quarts low on oil. During this process, the vehicle continued to experience drivability concerns including rough running/stalling and poor engine power. I am concerned that the vehicle may stall or experience significant loss of motive power while being driven in traffic. I routinely use this vehicle for commuting and transporting my family. Kia ultimately declined warranty coverage based on insufficient maintenance documentation. I am not submitting this complaint to dispute the warranty decision. I am reporting the underlying safety concern because the vehicle has experienced stalling/loss of power together with substantial engine-oil consumption, and the underlying mechanical cause has not been clearly resolved.

I purchased this 2021 kia Telluride new and have had it routinely serviced and maintained by authorized kia dealerships. At approximately 60,000–80,000 miles, the engine began consuming excessive oil. I reported the condition to the kia dealer at approximately 80,000 miles, while the vehicle was still within kia's 10-year/100,000-mile powertrain warranty. The dealer initially recommended a tune-up, but the oil consumption continued. During a later visit, the dealer identified an issue involving the oem oil-filter housing and replaced the affected component. Despite this repair and continued maintenance, oil consumption progressively worsened. The vehicle now has approximately 160,000 miles and requires approximately one pint of oil every 2–3 weeks. The current diagnosis indicates potential internal engine damage, including cylinder-wall scoring that may allow oil to bypass the piston rings and burn in the combustion chambers. I have been advised the engine may require replacement at an estimated cost of approximately $13,000. My primary concern is that this condition began and was reported to kia while the vehicle was still under the powertrain warranty, but the repairs did not correct it. Continued excessive oil consumption and internal engine damage create a safety concern because they could result in low oil pressure, engine seizure, stalling, or sudden loss of propulsion while driving. The vehicle is available for inspection, and its maintenance history, prior complaints, dealer repairs, and current condition are documented through kia dealership service records.

This is an update to my original NHTSA complaint (id 11755209) regarding an intermittent no-start/no-crank defect on my 2023 kia Telluride (VIN [xxx]). Since my original filing, the identical defect has recurred twice more, on xxx — once at approximately 1:01–1:30 pm est and again at approximately 5:03–5:17 pm est, the same day. In both incidents, the dashboard and infotainment system powered up normally, but the vehicle would not crank, consistent with all prior occurrences dating back to xxx. This brings the total documented occurrences to six between xxx and August 8, 2026, including two in a single day. In both August 8 incidents, my wife was stranded and had to be picked up because the vehicle would not start. This follows a dealer-confirmed and dealer-executed starter replacement (kia of cleveland, ro dated xxx, part #36100-3l160) that was performed after the dealer duplicated the fault on the vehicle and on a bench test — and a 4th recurrence on xxx, just 10 days after that repair. I have video evidence of all four August incidents (xxx, and the two on xxx showing the instrument cluster and infotainment fully powered with a no-crank condition. I am providing this update because the frequency of occurrences is escalating — two failures in a single day — despite a repair that was physically confirmed by the dealer's own testing. This strongly suggests the actual root cause (potentially an immobilizer/Smart-key system fault, ibu communication failure, or intermittent wiring/ground fault) has not been correctly identified, and the defect continues to pose an unreasonable stranding risk to occupants. I am concurrently pursuing a vehicle replacement request with kia America under customer care case #26211382. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving, car alerted “engine off! shift to p or n, then start engine”. I had to immediately pull to the side of the road and follow instructions. Due to previous unresolved issues car has had I recorded the message car was giving.
