Power Train Problems of Kia Motor Telluride - part 2

Borescope inspection of the engine shows multiple signs of internal mechanical failure involving oil control, piston ring integrity, coolant intrusion, and cylinder wall damage. Excessive oil buildup is visible above the oil control ring, far beyond what is expected at 59k miles. Cylinder walls show heavy polishing where cross-hatching should be visible, indicating loss of lubrication and abnormal wear. Carbon deposits are extremely thick; in several areas carbon has flaked off and been pulled downward into the cylinder, creating scoring. Straight vertical scoring marks cut through the normal diagonal honing pattern, confirming blow-by and damage to the cylinder sleeves. Evidence of coolant intrusion is present, including orange discoloration consistent with rust/coolant contamination, excessive moisture, and steam-cleaned areas of the combustion chamber. The intake valve and combustion surfaces appear abnormally clean, consistent with coolant steam-washing. This suggests head-gasket failure, a block or head casting defect, or ring damage (possible cracked scraper ring). Coolant in the cylinders can wash away oil from the bore, leading to rusted pistons and accelerated scoring. Multiple pictures show severe scoring and loss of lubrication. This compromises the ability of new pistons or rings to seal, meaning the cylinder walls would continue to allow blow-by, oil burning, coolant intrusion, and friction. Even attempting to polish or recondition these bores would enlarge them, causing piston flutter, noise, and long-term failure. Based on the level of damage, the engine is no longer safe or reliable. A seized piston could cause sudden loss of power at highway speeds, creating a safety risk. The observed defects indicate a potential manufacturing or casting issue that may affect other engines. The dealership and kia consumer affairs have been notified but there has been no replacement or resolution after 3 months of ongoing issues, and 8 weeks of holding my vehicle.

The vehicle decelerated in the highway, from about 70mph to 40mhp with no warning, no check engine light, and no previous symptoms, sounds or other indicators. The vehicle was brought to the dealer who advised the high pressure fuel pump went bad as well as the solenoid and ocv harness, causing oil to be forced through the harness. Kia refused to cover the repairs at 74k miles and it was fixed at the owner expense, even after kias long history of failed high pressure fuel pumps in many other models. We were in the fast lane and were almost hit by a semi, who was thankfully able to move over at the last minute, narrowly averting the deaths of both my children, myself, my nephew and brother at aprox 4am.

The Telluride has developed a shimmy. At first, the shimmy was noted at lower speeds, around 35 to 45 mph while under minimal load such as going uphill and slightly accelerating. The car was taken to the dealership. The tires were balanced. We were told no other problems. A month later, same thing, same result. We just took a 2700 mile trip. The shimmy is apparent at higher speeds and in all transmission modes of operation.

My torque converter is failing on my 2020 kia Telluride. This is a known issue among other owners of this model year, and I believe kia knows about it and is refusing to acknowledge because of how expensive it is.

The awd couplers continue to fail. We are waiting for the dealer to get parts in so they can be replaced again. The tech stated kia continues to install defective parts.

The contact's spouse owns a 2020 kia Telluride. The contact's spouse stated that while the vehicle was parked, the vehicle inadvertently rolled backwards and struck the contact’s aunt as she was exiting the vehicle. The contact’s aunt was taken to the emergency room by ambulance/helicopter, where she later succumbed to the injuries and was pronounced dead. The contact stated that the vehicle remained at the scene. In addition, before the incident, there was grinding coming from the gears. The contact was unsure what specific injuries were sustained. A police report was filed. The contact stated that the VIN was included in NHTSA campaign number: 24v214000 (power train); which the contact related to the failure. The contact had previously received the recall notification. The dealer was not contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 101,000. Parts distribution disconnect.

Car erratically shifts and provides more power to vehicle when it is not necessary. It often shakes in between shifting.

Summary of defect and repair history my 2024 kia Telluride ex awd has experienced repeated and ongoing transmission failures. The failures include the vehicle becoming stuck in 5th gear, unsafe acceleration characteristics, and loss of normal drivability. Two transmissions have been replaced, and the same defect continues to occur. The vehicle remains at the dealership today with the defect unresolved. Repair attempts and days out of service 1 transmission replacement 30 days returned but defect recurred. A warning lamp (check engine) did illumiinate after the first transmission failure, however did not for the second nor third failure. Failure was confirmed by kia dealership. 2 transmission replacement 47 days. Returned but defect recurred. Failure was confirmed by kia dealership. 3 current repair attempt 24+ not repaired. The vehicle has incurred three repair attempts and 101+ days out of service for the same defect. Failure was confirmed by kia dealership. Substantial impairment: use, value, and safety 1. Impairment of use ? the vehicle has been in the dealership’s possession for more than three months in 2025, making it unavailable for normal use ? driving attempts prior to service demonstrated lack of shifting, hesitation, clunking, and unsafe behavior ? the defect continues to occur despite repeated major repairs 2. Impairment of value ? a newer model vehicle requiring two full transmission replacement in one year and still malfunctioning has demonstrably reduced value ? transmission replacement history is discoverable and materially reduces market value 3. Impairment of safety ? transmission failure compromises safe acceleration, speed regulation, and predictable power delivery ? the failures occurred at low mileage, indicating a systemic nonconformity rather than normal wear, presenting an ongoing risk as a engineer with 20+ years of experience, I do believe the root cause is a wiring issue (e. G. Shorted wiring harness), not a transmission failure.

The check engine and oil pressure light will start to flash when starting to brake. While this is happening the car starts to shake, stall, and you struggle to accelerate. This has happened multiple times and the last time was in the middle of an intersection. Kia dealership did not fix the issue the two times I took it to the shop. The third time in they did some test and said it was an oil consumption issue and the piston rings in the SUV have failed and the car needed a new engine. This car is a 2020 Telluride with 78,759 miles on it. This issued started well before the 78,759 miles. Oil consumption has been a major issue with other kia models and they have not seemed to fix this issue with the Telluride. I believe they have replaced engines at an extremely high rate and now they are denying engine replacement under their warranty and stating piston ring damage is not covered under the warranty due to high oil consumption. You guys have issued a recall on 2021-2023 seltos and soul models for piston ring failure and now they do not want to start replacing Tellurides. There is a facebook page out there labeled kia Telluride issues with oil consumption being a big issue in the comments. Kia stating they will not cover the engine replacement is not only wrong is it a safety issue. I truly believe they know this is a serious issue and have not done anything to correct it. This vehicle is still under warranty and I am still in contact with the dealership to fix this issue.

For the past year to year ½ I have brought my car in for concerns with idle, hesitation when accelerating, stalling out, etc. This has put me in compromised situations when in traffic, at stop lights and when trying to accelerate to get on the highway. I was told it was fine, until it was not. Now my engine needs to be replaced. What I discovered in my car was their worksheet on issues that they never shared with me. Identified issues on this report: fault code 6, po300400 - history, cylinder misfire, po30500 - history, cylinder misfire po34100 when going back for a 'simple' 1000 mile oil check, I was told there was not enough oil loss to identify concern. When I checked my own oil after another 1000 miles, kia then pursued. In researching, there is a history of these engine problems and engines needing to be replaced with kia. This is unacceptable and has compromised safety and any value I hoped to have with my car.

The vehicle was parked(placed in park on gear shift) in a friends driveway, facing upward on approx. 15deg incline with the engine idling. My wife exited the vehicle and walked around the front of the vehicle to the houses front entrance where she spoke briefly with the owner inside the front door. On leaving the house the car was gone from where it was left parked. My wife found that it had rolled up the driveway incline until it hit a couple of pine trees at the top end of the drive and stopped. She opened the door and found the gear shift still in the parked position at which point she entered the car, placed it in reverse and backed out of the tree branches and took photos. The incident was immediately reported to kia America and the dealer. The vehicle has been at the dealer for 3 weeks now with no resolution, undergoing "testing". They say it is not operating the way it should be, but they have not been able to identify or correct the issue. Kia America has told me the issue has been elevated to kia factory tech support. Other than scratches there appears to be no major damage. Photos show driveway, trees that stopped the vehicle and debris and scratches.

This is a follow-up to complaint #11666572 regarding my 2020 kia Telluride (VIN: [xxx] ), with urgent concerns about ongoing safety violations and abusive conduct by greenway kia east and kia America. On June 26, 2025, kia America reversed its prior refusal and agreed to reimburse uber, rental, and towing costs—but only after I filed multiple complaints. Earlier, they claimed to have no influence over the dealership, which had refused all reimbursement after I complained about service manager gina. Worse, on June 27, the dealership responded via bbb telling me to contact gina again—the very person I formally complained about for unprofessional and negligent conduct. This isn’t just mishandling; it is degrading, retaliatory, and dangerous. Key safety/legal concerns: • my vehicle was returned on may 31, 2025, with dangerously low coolant, just days after engine replacement—posing a critical safety risk. • the service manager dismissed my concerns until I insisted, then acted with open disrespect. • repairs were withheld may 19–28 unless I paid $1,833. 77, despite warranty coverage. Only after I came in person on may 28 did they reverse and offer free service. • I was charged $580. 97 for a diagnostic test tied to a manufacturer defect that led to engine replacement—still not refunded. • the pattern of neglect, retaliation, and deception from both the dealer and kia America endangers drivers and violates federal safety standards. This dealer has acted with impunity since may 19, 2025. Their behavior is abusive, unsafe, and incompatible with their licensing. I urge NHTSA to investigate whether greenway kia east should retain its dealership license. Their conduct undermines public safety and federal standards. A full follow-up and attachments were sent to nhtsamedia@dot. Gov from [xxx] . Please contact me for documentation. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On [xxx], my kia Telluride received a warranty engine replacement at greenway kia east in orlando, FL. Just two days later, on [xxx], the engine overheated while I was driving with my young child. The temperature warning light came on. I stopped immediately and opened the hood — there was no coolant in the system at all. This failure occurred immediately after a major engine replacement, suggesting that the dealer failed to fill or properly check the coolant system. I was left stranded near a daycare and had to call a third-party tow truck because kia roadside assistance estimated a 90–120 minute wait. This put my child and me in serious danger. Despite the dealer’s clear negligence, I was sent an invoice for $1,833. 77, blaming me for the damage. Upon retrieving the car on may 31, 2025, I personally checked under the hood — the coolant level was still below the min line. When I pointed this out, the service manager said, “we’re not required to top it off, but if that satisfies you, we’ll put some in. ” this is extremely unsafe and irresponsible, especially after a critical repair like an engine replacement. Later, the dealership even claimed to kia America that the engine was not replaced under warranty, contradicting their earlier confirmation. This kind of conflicting information, combined with unsafe practices and disregard for basic safety protocols, raises serious concerns about consumer safety and the dealership’s integrity. To make matters worse, kia America closed my case ([xxx]) on June 10 without notifying me or giving me a chance to respond. I received only one dropped call from an unknown number, and no voicemail or follow-up communication. A formal complaint was mailed to kia America on June 11, 2025, and I am currently waiting for their response. On June 12, 2025, I also filed a complaint with the better business bureau (bbb). Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have a 2020 kia Telluride that I bought brand new from kia. I have performed regular maintenance on the vehicle and performed the repairs required by any recalls. When my vehicle surpassed 75k miles, the vehicle started having issues with excessive oil consumption. I had my vehicle serviced at 75k miles with the oil changed. When my vehicle was passed 79k miles, the vehicle started stalling, piston misfiring, and engine started vibrating. I took it into the dealer, and they performed diagnostic tests. The determined pistons were working fine but my oil level was very low. This was around 4k miles after my oil change. Kia requires oil changes every 7500 miles. I had the dealer change the oil. Once again, when my vehicle was approaching 4500 miles, the vehicle started to vibrate, piston was not filing properly. I checked my oil level, and it showed very minimal oil on the dip stick. The oil level was well below that was needed for the engine to properly operate. I put closed to 5 quarts of oil to get the engine to the oil level it needed. I am concerned that the excessive oil consumption can lead to the vehicle stalling on the road resulting in collision with other vehicles resulting in bodily injury or harm. According to kia the oil consumption is fine. How is consuming 5 quarts of oil in 4500 miles fine when the manufacturer states oil changes are required every 7500 miles? the engine itself has a capacity of 6. 9 quarts. At the rate my engine is burning oil, I would need over 7. 2 quarts of oil to drive 7500 miles. Additionally, having an engine continuously operating with low oil would result in engine damage and thousands of dollars in repairs. The problem I am having in my vehicle is experienced by thousands of kia Telluride owners. It's the same problem kia has had in the past with other models. Kia is trying to avoid repairing their defective vehicle and placing the burden on the consumer.

The front axels are leaking and the transmission is lagging/jerking while accelerating.

Windshield cracked from minor item being thrown up by car in front of me. Engine burns out no oil on dipstick with regular maintenance engine tick transmission slips axle boot ripped oil pan cracked due to it being faulty.

We have had multiple issues with this car. First the pearl white peeling off on hood and above the windshield. Second cv3 axles boots leaking on our vehicle and multiple others at the kia dealership. Third burnin oil even with good maintenance records. 3rd sunroof won’t open or close now for no reason at all. 4th back seat now attempts to fold at random times. Even with our kids in the seat. 5th oil housing leak. 6th cel comes on and off randomly causing it to run rough. 7th screen is now to have issues of not working right. We’ve had to pay out of pocket for multiple things. Including the paint. We’ve spoken to service department and common issue they don’t see why it’s not a recall by now. Dealership is no help. Beware.

The car is a 2020 kia Telluride. It was purchased in August 2023 at the time it was leaking oil took it back to the dealer and they replaced the housing put in a new filter and said all was good . For a year. It constantly needed oil took it back to the dealer, said that everything was fine. I would be driving and the car would stop. The oil lamp would come on and I would have to drive and put more oil in it every week. I was putting a quart of oil into the vehicle just about weekly because it seemed to be leaking oil and just a dying out. Just a few days ago after putting a quart of oil in I’m driving my vehicle and all of a sudden smoke comes out of the back a little bit out of the hood. It just stopped all the lights went on the car went dead. Had to call the police get the vehicle towed to the dealer at that point was told the engine had died. They want to put a new engine in the car which it’s a five year-old car. It should not need a new engine what is causing it to need a newengine. Ever since I purchased the car, it had oil problems so did the oil lead to engine failure. I know I’m not the only one that this has happened to every time I would take it back to the kia dealer. I was told everything‘s fine everything was not fine never got any warning lights or signals, except for when I was driving the car would literally sputter and stop at a light. I would have to restart it and then go get oil.

My vehicle has been repaired multiple times for leaking oil in different areas.

Car has been brought to kia for transmission issues multiple times and the associate tells me to just tighten the gas cap to get the light to go off. The car is not shifting properly and will "jump" or "lunge" forward while driving. I have noticed that the rpm's will jump and bounce around, seemingly down shifting, then shift again, and then down shift again, which causes jerking motion. The reason I initially took the vehicle in was for a "shake" or "wobble" when accelerating up a hill (semi steep incline) or at freeway speeds (55-70mph). In these instances, the vehicle will have a hard time shifting and temporarily lose momentum causing concerns for me and other drivers on the road. The transmission light will go on and I call kia to be told to tighten the gas cap. I recently brought it in for the third time and they diagnosed something different. I have mentioned the transmission each time, but they have focused on other items and not the transmission. I have had the shocks replaced, the tires replaced, alignment performed, and the problem still persist. However, the dealership will not look at the transmission and says that it is the other items, but the issue still remains after fixing the other items. The shock failure caused other items to wear out and the dealer should be on the hook for those items. I have brought the vehicle in dating to last year for the transmission issue with no help from the dealership. Please take action so that we don't lose our lives or put others at risk for injury.

Transmission constantly slipping after driving and transmission gets warmed up. Vehicle continues to rev up and enter high rpms before changing gears and then jolts the vehicle as changing gears. Also steadily leaking coolant fluids, have taken vehicle to the dealership as of now three times to have the coolant issue serviced. Repairs are still not complete to date.

Issue: engine stall & loud tapping/grinding noise vehicle only has 1,100 miles and has stalled about 5 times when slowing down to about 10mph & then accelerating again. Issue has also happened when going about 3mph & then accelerating. About 10sec stall & then vehicle takes off. Several of the stalls happened even though the auto/start switch was engaged to disable feature since I thought maybe a bad switch was the issue causing the stalls, but stalling happens with it on & off. Another issue engine makes a tapping noise when in gear & accelerating up to about 1200rpm. Issue has been getting louder since purchase. At 1100 miles started car & pulled into garage after vehicle set for about 2hours (75f outside), upon doing this the engine sounded terrible like there were a handful of marbles in the engine, super loud sound, at this point made appointment with dealer, but they are so backed up vehicle can't go in for service for about 2 weeks per no loaner car available until then, since it can take up to 1 week to get looked at. Will update with their findings but looking at form pages & you-tube videos it seems like the ongoing engine tapping complaint resulting in an engine replacement & maybe part of the 2024 recall valve spring breaking resulting in the loud marble sound I am hearing. Car stalling is a major safety concern since a few of the stalls happened when pulling in front of traffic going 60mph.

I’ve taken my vehicle to kia a few times about my transmission sputtering and the first time they told me I needed a transmission flush, I paid $250. 00 to have it done just to have it continue to happen and every time I bring it there they say they aren’t seeing or feeling anything. It’s still doing it. Also I opened my sunroof and it hasn’t been used much since I bought it in 2022 and now it’s stuck open. Took to the dealer just for them to tell me I have to pay $140 diagnosis fee and my warranty most likely won’t cover to fix it. I purchased the platinum bumper to bumper warranty!.

When you are stuck in the snow and start to spin, the awd kicks out and you cannot move. Very big issue for anyone that lives in an area that snow accumulates.

Cv axel vibration issues. Seems to be a common complaint on 2020 Telluride but no recall. Car is unsafe to drive.

The contact owns a 2022 kia Telluride. The contact stated that after his wife had parked the vehicle and left the front driver's side door opened while there were two passengers in the rear seats. The contact stated that his wife unloaded the vehicle and walked towards the front door. The contact's mother-in-law and daughter who were in the residence noticed that the vehicle was rolling back and alerted the contact's wife, who turned around and ran after the vehicle. The vehicle crashed into the rear passenger's side of another parked unoccupied vehicle. The vehicle continued to roll back until it crashed into a palm tree. The contact stated that none of the passengers occupying the rear seats sustained injuries. The vehicle was driven back to the driveway. The contact stated that the front driver's side door which was opened at the time of the incident, became bent and damaged. Additionally, the rear of the vehicle was damaged. The contact stated that the incident was recorded by his front door camera. No police report was filed. The vehicle was then towed to an autobody repair shop to be repaired. The contact stated that the recall of NHTSA campaign number: 24v214000(power train) was previously completed on the vehicle; however, the recall remedy failed to fix the failure. The dealer was notified of the failure, but no assistance was provided. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and a case was filed. The contact sent a recording of the incident to the manufacturer, but the manufacturer denied assistance. The failure mileage was approximately 36,000.

Component/system failure: the engine and lubrication system appear to be malfunctioning. The vehicle has repeatedly experienced sudden engine shutdown while stopped at traffic lights and during low-speed operation. The dealership has identified oil leakage involving the oil pan and oil filter housing and has indicated there may be an internal oil leak within the engine. The vehicle is available for inspection upon request. Safety risk: when the engine shuts off unexpectedly, the vehicle loses propulsion in active traffic. This creates a risk of rear-end collision and prevents immediate maneuvering out of traffic flow. The loss of engine power while stopped or moving at low speeds presents a serious safety hazard to myself and surrounding drivers. I am concerned that the suspected internal oil issue may lead to catastrophic engine failure while driving. Dealer confirmation / reproduction: the issue has been reported to the dealership multiple times beginning in January 2025. The vehicle has undergone multiple inspections and repair attempts, including partial fuel injector replacement, battery replacement, and an oil consumption test. The dealership has acknowledged oil leakage and has stated that replacing the oil pan gasket and oil filter housing may not resolve the suspected internal oil leak. The defect has not been permanently corrected. Inspection by manufacturer or others: the vehicle has been inspected multiple times by the dealership. The matter has been escalated to kia corporate for review. No police or insurance inspections have occurred, as no collision has yet resulted from the stalling events. Warning lamps / symptoms: during each stall event, the check engine light illuminates along with multiple dashboard warning lights. The stalling first began in January 2025. Oil-related concerns and possible oil loss were reported during prior service visits. The condition continues despite repair attempts.

While traveling at highway speeds between 65-75mph the vehicle with violently shake while shifting and then lunge forward. However, during the shaking the vehicle is hard to control and feels like it is going to just shut off. This scenario primarily happens on flat roads at the above mentioned speed. However, we have noticed an issue with the vehicle while turning corners and accelerating, as well as, when going up hills or steep highway sections. The vehicle has a v6 but seems to struggle shifting when trying to accelerate even to 40-50mph. In some instances the vehicle has labored up a hill and seemingly doesn't want to downshift and pick go faster. It seems that this issue has triggered a TSB from kia, but the issue has potential for elevated risks for other drivers on the road. If the vehicle is unable to maintain freeway speeds or climbing speed, then it poses a risk to traffic on either side of the road and the potential need to pull over. It seems that the vehicle loses power or momentum and would make it very dangerous to get off the road or onto the shoulder. The violent shaking could cause a driver to panic and lose control of the vehicle while at highway speeds and needs to be investigated.

Oil filter, housing leaks where it bolts to the motor this could become a fire hazard but the exhaust close to it.

Vehicle began to shake when approaching 40mph or greater. Mechanic at dealership stated bolt from driveshaft to rear coupler was missing with two other bolts loose. Missing bolt threads were rusted as if bolt was never installed from factory as vehicle only has 12,000 miles. No warning messages displayed, only symptom was vibrations when approaching 40mph or greater.

I was driving and stopped in the center lane and the SUV would not move. I was left in an unsafe position. I was there about 10-15 min and got pushed out of the road. I turned the SUV off and on a few times with no difference in response. I let the SUV sit there about another 5 min and was able to move the SUV and the problem has not occured today but it does seem to be shifting a little hard and have noted that recently. I saw something online about NHTSA id numbers 11425571 and 11354498. That might be relivent but I was trying to to find more information on those.

The vehicle intermittently fails to shift gears and loses acceleration without warning, creating a serious safety hazard. The problem began in October 2024 when the check-engine light first appeared and has continued since. Despite multiple repair attempts by the kia dealership—including replacement of the fuel pump, fuel pressure sensors, and ecu—the root cause remains undiagnosed, and the defect persists. When the vehicle was brought back in August 2025, the dealer’s latest recommendation on 9/30/25 was to replace the injector harnesses and front wire assembly, but they cannot guarantee this will resolve the issue.

High oil consumption. Oil needs added frequently or it gets low and car doesn’t run correctly. Transmission slips daily at low speed first thing in the morning. When making slow turns tires tires don’t seem to remain steady/grip. The car is hoppy like there is a traction problem. Tires have been replaced and issue remains.

There is an ongoing problem with the awd coupler on every model year of this vehicle and other kia/Hyundai awd vehicles. The problem occurs at lower speeds (35mph or less) while turning, and/or when starting from a stop turning either left or right. The vehicle produces a binding or slipping feel in the rear wheels along with a clunking noise from the rear of the vehicle. This is dangerous because the vehicle loses traction/power when its needed most during slit second decisions. Many of these couplers are failing early in the life of the vehicle. Mine is at 27k miles, however I believe the problem started long ago, closer to 15k miles. Kia knows about this issue but has failed to come up with a reliable solution. This is four model years now with the same issue. Kia has released TSB after TSB on this, and even recalled it early in the life of their debut model, the 2020. However, there are still reports of replacement parts failing again around the same amount of milage. It would be great if a wider recall can be issued to address this ongoing problem that seems to affect every model year so hopefully kia can find a more reliable, quality part to replace the consistently failing part.

Vehicle began having issues around 60,000 miles. Stutters and slips between 2nd and 3rd gear. When on an incline the issue is much more prevalent. On a steep incline, the vehicle is like lurching it is so prevalent and it feels as though the vehicle is going to give up. Around 45 mph, the vehicle begins vibrating; as speeds increase, the shaking (left to right) becomes increasingly violent. At times, it feels as though the vehicle is going to shake off the road. The issues I primarily when accelerating, and when the gas pedal is released, the shaking slows almost to a stop. Tires, balance, and alignment checked multiple times over the course of the issue and tires are changed seasonally. Took to dealership multiple times to be told there was no issue with the vehicle and it was operating properly. Just over 100k miles, back at the dealership and there is suddenly an issue found. Was told at dealership that passenger side front axle inner race is damaged and needs replaced. Took vehicle to local mechanic since dealership had jerked us around so much over the issues, not repairing, keeping car for extended amounts of time without a loaner vehicle, etc. Local mechanic did a lot of research. This is a common complaint of the Telluride and kia is aware but is not doing anything about it. Mechanics recreated issue immedately said rear driveshaft had movement it shouldn't and replaced. They also serviced the transfer case and transmission. There is a TSB issued on this, but research suggests that it is not resolving the problems and kia dealerships are not acknowledging the issue until out of warranty and TSB doesn't cover the repairs even though it is faulty manufacturing.
