Power Train Problems of Kia Motor Sorento - part 1

I am reporting a serious safety defect regarding my 2022 kia Sorento hybrid (mileage: 91,661). The vehicle was diagnosed with an internal short in the egr (exhaust gas recirculation) control unit (error codes p0404, p049d). Upon inspection, significant engine oil intrusion was found inside the egr unit. The egr system is designed to handle exhaust gases only; the presence of liquid engine oil indicates a critical failure in the powertrain system (likely the pcv system or turbocharger seals) which is forcing oil into the intake/exhaust tract. Safety risk: this defect causes the egr system to short-circuit, which can lead to unpredictable engine performance, reduced power, or sudden engine stalling while driving. Any sudden loss of power on a highway poses a severe risk of a rear-end collision. Furthermore, oil intrusion into electrical components increases the risk of thermal incidents or localized fires within the engine bay. Despite the vehicle being within the 10-year/100,000-mile powertrain warranty, the dealership (suntrup kia south) is refusing coverage, claiming the egr is not a powertrain component, while ignoring the fact that a powertrain failure (oil bypass) is the root cause of the damage. I request NHTSA to investigate this "oil intrusion into egr" issue as it appears to be a systemic defect in kia’s hybrid powertrain that compromises vehicle safety.

Car is in shop 3rd time 2020 Sorento with 2. 4l thete ii gdi engine. In may e went in p1326 code of death, knocking and blinking light. They put a band aid on. Back in September more issues, oil gasket valve cover and 4 spark plugs. Another bandaid, westarted seeing oil, I thought we were nuts because it was just fixed. Check engine light cane on, read 4th spark plug shot that they put in on 9/25. Tatvfirst rried sating 300 for plug and done. Then day after head mechanic says we need a new engine but all receipts not available. They're not filing a claim for an engine, these engine are blowing up and failing everywhere they just haven't gotten to year 2020 yet in law suits or settlements. When p1326 originally happened we were on the highway and it just decellateared and loud knock! luckily we were okay and got over fast. With each issue car was immediately brought back to the kia dealer, the sane dealer I bought the car new off lot in 2020.

This incident started within the first 100 miles of ownership. The dealership hasn’t been able to recreate the incident. I put my 2025 kia Sorento in the “automatic” drive position. I start driving and my transmission won’t shift gears. I looked down at my dashboard and it shows the vehicle is in “manual” drive gear 1. I look at my gear shift and it shows the vehicle is in “automatic” drive position. If I push the vehicle to its redline or approximately 5000 rpm’s the vehicle shifts and dashboard changes from “1” to “d”. In summary my transmission is malfunctioning and shifting intermittently on its own from automatic to manual drive and the gear shifter is always in the automatic shift position. This happens several times a month. I video taped the incident because the dealership didn’t believe me when I told them this keeps happening.

Based on my best assessment, the issue appears to be related to the transmission pump. The vehicle experienced transmission malfunction consistent with a failing transmission pump. This vehicle has an active federal safety recall listed under its VIN; however, the local dealership in puerto rico refused to honor the recall and attempted to charge for the repair.

Today is 12/15/2025 about a month or 2 ago I was on the highway coming from south carolina to north carolina when the engine revved up unexpectedly without input. It has hda2 and that was doing most of the work. The vehicle started to speed up beyond the set limit and once I hit the brakes and manually shifted I was able to regain control. Last week the vehicle made a small noise that I wasn’t sure about. I called the dealership thinking that it could be a transmission problem. When I called they didn’t seem concerned and asked me to bring it in Monday (today). I had no lights or error codes (and still don’t) on the dash and they did not recommend that I don’t drive it so I continued using the car. Last night it made a horrendous noise started revving on its own and shifting very hard ans if something was coming apart. This morning on my way to the dealership the car completely seized up at an intersection. The car has 47900 miles on it. It’s a 2025 and the transmission seems to have completely blown. Ive read online several complaints about the transmission on these vehicles and think that they may be a major concern. For a new car to have this type of issue locking up while on public roads and smoking is absolutely a hazard. My only saving grace is that it happened at an intersection and not on the highway where an accident would have been inevitable. Please look into the dct transmission on kia Sorentos. Particularly x-line sx prestige models. It is a highly unsafe vehicle. Another issue that the car is having is a clicking noise on the steering column that seems to be getting much worse over time and im afraid will result in loss of steering. Im having them check it out as well. The vehicle never showed a malfunction and I’ve attached a screenshot of the app showing it in perfect health despite being undrivable. I still have no invoice and no police report was made.

On 3 separate occasions, while idling, the engine will sputter as if it’s about to cut off. The rpm will rise and fall and the engine will rev up and down and finally it will quiet down. Once the light is green, it is able to drive as normal. At the next light the same thing happens and the engine revs up and down sounds like it’s about to die. At a certain point the car will lose propulsion,(hard to notice at first when it’s stop and go traffic) even with the pedal all the way down, making it difficult to drive at a safe speed. The car will operate this way in a very limited capacity w stuttered propulsion for a minute or two then a warning symbol and alarm sounds letting me know there is a safety issue with the hybrid system and to stop safely. The car then becomes completely unresponsive and you must stop immediately and shut the car off. Once restarted the car jolts back up and operates somewhat normally.

Incident #1: [xxx] the vehicle would not accelerate after coming to a stop at an intersection. The vehicle would not exceed 20 mph with oncoming traffic from both the east and west as I was turning west from a north bound road. On coming traffic was traveling between 45 and 50 mph. I was clearly nearly broadsided. The car displayed flashing lights on the dash as I was attempting to accelerate. Depressing the accelerator did not increase my speed. The car kept at a 20 mph speed for the 1/2 mile I traveled to pull off the road in a safe location, causing traffic to be disrupted until I could pull off the highway I had the car towed to the kia of round rock dealership November 17th. The car remained at kia until December 3rd where they were unable to duplicate the problem. I requested the problem be referred to kia in California. Kia of CA was totally unresponsive when the problem could not be duplicated. Incident #2 [xxx] vehicle failed to respond to accelerate after stopping before attempting to enter a four lane highway. (no traffic was visible. ) the car would not accelerate more than 20 mpr, the speed limit was 55 mph. For the 1. 5 mile trip home, I turned on my hazard lights, kept to the right and flagged traffic around me. The car never exceeded 20 mph.

While driving from phoenix to tucson in midday traffic, the vehicle displayed a "check transmission" error message. Immediately following this warning, the vehicle experienced a significant loss of motive power while navigating a busy intersection. The car would not shift gears appropriately to maintain speed or move out of the path of traffic, which created an immediate risk of a collision. I was able to avoid an accident, but the vehicle's inability to accelerate or change gears left me stranded in a hazardous location. Component failed: transmission/transmission control module. Safety risk: the sudden loss of power in an intersection put me and other drivers at risk of a high-speed side-impact or rear-end collision. Warning symptoms: the "check transmission" message appeared moments before the failure. Inspection status: we have had the recall taken care of on January 25 , 2023 with 8810 miles at peoria kia initially. The incident happened on December 6, 2025 and the vehicle was taken to royal kia on December 6, 2025 for inspection. ".

Car has 77,593 miles. The oil light came on only at idle. Immediately hauled to dealership and was told it was a faulty pressure switch and not covered by the warranty even though its part of the powertrain and the earlier models had the same problem and were extended. Should I expect every 77,000 miles or so to have to spend $1700? the tech said no because they are replacing the known faulty switch with new version of it.

The contact owns a 2022 kia Sorento. The contact stated that upon starting the vehicle, the vehicle failed to accelerate while depressing the accelerator pedal. There was no warning light illuminated. The contact restarted the vehicle; however, the failure persisted. The contact called a mobile mechanic to the residence, and the mechanic diagnosed the vehicle with a defect in the transmission. The mechanic informed the contact that there was a recall on the model vehicle related to the transmission. Upon investigation, the contact discovered NHTSA campaign number: 22v760000 (power train); which was linked to the failure. The contact called several dealers in the area and was informed that the vehicle was not included in the recall. The manufacturer was notified of the failure, and the contact was provided with the same information as the dealer. The vehicle was not repaired. The failure mileage was approximately 55,000.

Vehicle: 2025 kia Sorento (leased) VIN: [xxx] mileage at failure: 11,345 incident dates: March 23, April 27, November 28–December 1 type: loss of power / electrical failure / safety hazard complaint description: I am reporting repeated electrical failures and complete loss of power in my 2025 kia Sorento that created unsafe situations for myself and my children. The first failure occurred on March 23, approximately 2½ weeks after leasing the vehicle. The vehicle died without warning and had to be jumped. I brought it to the kia dealership, but service would not perform a diagnostic without an appointment and sent me home with no repair. The second failure occurred on April 27. This time the vehicle was completely dead again. Kia’s service manager retrieved the vehicle from my home, diagnosed a failed battery cell, and replaced the battery. The third failure occurred between November 28 and December 1. The vehicle was again completely inoperable. I attempted to jump the vehicle on multiple days, but it would not hold a charge. I was stranded without transportation. The interior doors and trunk would not unlock because the power locks failed, and my belongings and large business related were inaccessible. Headlights flickered like a strobe light before the vehicle lost power entirely. Kia towed the vehicle from my home on December 1. These repeated electrical failures have resulted in multiple incidents of being stranded, including with my children, and have caused loss of use of the vehicle for several days. The defect is unpredictable and creates a serious safety concern, especially because the vehicle can lose power without warning and I am unable to unlock the doors. This raises a serious safety concern when transporting children. I am requesting that NHTSA document this as a potential electrical system safety defect.

Our 2016 kia Sorento had 86k miles on it, loud knocking began and days later catastrophic engine failure. Rods and bearings are busted on my 3. 3 liter, v6 gdi engine. It died while my wife was driving it to the dealership. Estimated repair is 19k, metal shavings in the oil. It is available for inspection. My wife was driving it on the highway when the engine failed. Dealer confirmed the rods and bearings were broken.

The vehicle is a 2016 kia Sorento equipped with a 2. 0l turbo theta ii engine subject to the ksds (knock sensor detection system) safety recall. The original engine was replaced at approximately 70,000 miles under kia’s engine service program. The replacement engine currently has approximately 32,000 miles. The vehicle developed internal engine damage diagnosed by a kia dealership as a burnt exhaust valve. A burnt exhaust valve indicates abnormal combustion conditions such as lean operation, pre-ignition, detonation, timing deviation, injector malfunction, or lubrication failure. These are conditions the ksds recall was intended to detect and mitigate. Kia consumer affairs denied warranty coverage, stating that the extended warranty applies only to rod bearing failure and that no further escalation would be pursued. Kia consumer affairs declined to escalate the matter for district parts & service manager review and directed the owner back to the dealership. During the prior engine replacement, the dipstick was observed to be glued in place, raising concerns regarding oil level accuracy and lubrication integrity on the replacement engine. This complaint is submitted due to concern that a ksds safety recall-related engine failure involving abnormal combustion was not properly reviewed or escalated, and that recall procedures were not administered in accordance with their intent.

Beginning at approximately 750 miles on a brand-new 2025 kia Sorento hybrid ex, the vehicle experienced a flashing check engine light accompanied by severe shaking while driving, rough idling, loss of power, and loud engine/exhaust noise. The vehicle became difficult and unsafe to operate due to the vibration and reduced drivability. These symptoms appeared suddenly on November 22, less than three weeks after purchase. The vehicle was taken to the dealership on November 24. Their technician retrieved diagnostic codes p0300 (random misfire) and p0304 (cylinder #4 misfire) and identified a failed ignition coil on cylinder #4. The coil was replaced, and the dealership reported the issue resolved. However, less than 24 hours later, with the vehicle still under 800 miles, the exact same symptoms reoccurred: heavy shaking while driving, vibration while idling, loss of power, and unstable engine operation. This indicates the underlying issue may be more serious than a single coil failure. The problem has been reproduced and confirmed by the dealership, and the vehicle is currently back in their possession for further inspection. A loaner vehicle was issued because the vehicle was not safe to drive. The sudden shaking, engine misfire, and loss of power created a significant safety risk, especially if this failure were to occur at highway speeds or while turning across traffic. Given the extremely low mileage and recurrence immediately after repair, this may indicate a broader defect affecting engine performance or ignition components in this model. The vehicle remains available for inspection by NHTSA, the manufacturer, or investigators.

Car is losing power, won't go into gear, slipping.

The contact owns a 2017 kia Sorento. The contact stated that while driving at an undisclosed speed and attempting to accelerate, the vehicle was shifting extremely roughly. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission due to the vehicle not receiving a required software update. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was 141,128.

Engine has a leak, the engine oil sensor was defected ,front axel leak and needs replacement.

I am reporting a serious defect involving my 2017 kia Sorento 2. 4 liter gdi engine (VIN [xxx] ) at approximately 84000 miles, while still under the powertrain warranty, I brought the vehicle to the dealership from which I purchased it (hutchinson kia in macon GA) due to engine hesitation and abnormal performance. I was initially told the engine might need replacement, but the dealer later claimed the issue was only a relay/software problem and performed a software update (likely the ksds knock sensor update) at approximately 94000 miles, the engine suffered a sudden catastrophic failure while driving on the interstate, the failure was abrupt and created a dangerous situation in traffic. The vehicle is now inoperable. The engine is equipped with the theta ii gdi engine, which has a documented history of bearing and connecting -rod failures, fires and sudden engine seizure. Kia is refusing to cover the failure, even though the symptoms began during warrantly and the ksds update was reportedly completed. This appears to be consistent with the widespread theta ii engine safety defect previously investigated by NHTSA. The sudden failure of the engine posed a significant safety risk to myself, passengers and other motorists. I am requesting the NHTSA review the incident and evaluate whether kia is properly honoring required safety-related engine replacements for thet ii gdi equipped vehicles. Thank you.

Our 2025 kia Sorento has exhibited several issues with shifting into gears especially from 1-2 gear there is hesitation, hard shifting, where it has delayed engagement, rough or jerky shifts, and a feeling of power loss while driving. It has a hard time getting into 3rd gear and just stalls, dragging at 1st/2nd when attempting to accelerate and coming down from 4th gear back into 2nd and 3rd. A "check transmission' warning light has appeared on the dashboard. This is teh second time we have had this issue. The car only has 16k miles on it, we have had it for 12 months exactly now and only drive it locally.

My vehicle has a slow speed pick up and I’m getting code p0018 and has very rough idling !.

The manufacturer was made aware of the failure. The contact referenced an unknown recall with a similar failure description; however, the VIN was not included. The failure mileage was approximately 109,200.

The vehicle is shifting weird out of first, knocking sound. A code of p1326 skds is showing on diagnostic. This was supposedly repaired by kia a few months ago from a recall. I am questioning if they corrected and inspected the recall appropriately, due to this being the issue. The car is now unable to be driven because I do not want to do more damage.

My 2016 kia Sorento sx awd shows a noticeable delay in the powertrain when shifting from park into first gear. The car hesitates before moving, which affects drivability and feels like a transmission lag. I consider this a safety issue because the delay could cause the car to stall unexpectedly. I’m especially worried about driving with my children or merging onto highways, where a stall or hesitation could lead to loss of control and increase the risk of an accident.

On 10/3 driving at roughly 60mph on the freeway, when going to accelerate, the vehicle would not accelerate with no power going to the engine. The gas motor was not engaging, and the car rapidly decelerated to around 20mph in an incredibly unsafe situation. Coasting it off the freeway, it was towed to the local kia dealership. No warning lights or any indicators went off during that event. 10/9/2025, I picked up the vehicle after they replaced the high-pressure fuel pump and high-pressure fuel line, I noticed the battery was very low and thought it would charge while driving. As I left the dealership, the vehicle did not engage the gas engine and quickly avoided acceleration - no power was going to the engine. The battery reached a catastrophic low, and the engine failed in a busy intersection - creating another extremely unsafe situation - as I was turning around to return to the dealership. This time the hybrid system warning system went off and the battery and oil lights went on. While waiting for the tow truck, the vehicle would not turn off. It is currently with the dealership, 41k miles on vehicle, 1 year old.

After driving the kia Sorento and parking it for a little bit then restarting it again the transmission jerks very hard at times and sometimes it’s moderate. Its an on going issue. It starts happening after the car is being driven but on a cold start like overnight while its parked and the next day you turn the car on you dont feel anything until you start driving it then parking it and turn it off to go inside the store or something and once you come back out to start it you will feel it. My car only has 45k miles on it.

Vehicle is showing symptoms and issues related to a recall on 2021 kia Sorento transmissions. The vehicle hesitates shifting gears and there is no manual shifting mode available. Vehicle also has issues when accelerating due to the hesitation in shifting the gears. This vehicle was not included in the recall for this issue however it is the same issue as the recall describes.

My check engine light came on and my SUV started sputtering so I pulled over called my husband who came and had it towed to langdale kia of valdosta, GA.

The contact owns a 2025 kia Sorento. Upon starting the vehicle and shifting into reverse(r); the vehicle failed to respond with the message "service in" displayed on the instrument panel. The contact repeatedly depressed the accelerator pedal, but the vehicle failed to respond. The contact placed the gear shifter back into park(p) and then shifted back into reverse(r) and the vehicle started to accelerate slightly before coming to a complete stop with the accelerator pedal depressed. After repeatedly depressing the accelerator pedal, the vehicle jolted backwards. The contact decided to park(p) the vehicle and scheduled an appointment with the dealer for service. The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was 4,850.

The safety hazard began with a pattern of ignored warnings by the authorized dealer network. On Aug 15, 2025, I brought the vehicle to luther kia of bloomington for a check engine light. The dealer simply cleared the code without diagnosis, failing to catch early signs of engine trouble. On sept 22, 2025, the engine failed again. I drove the vehicle in unsafe "limp mode" to luther Nissan kia [xxx] ). They found the engine was "4 quarts low on oil" (severe starvation just 37 days after a dealer oil change). Despite this catastrophic finding, they failed to diagnose the root cause and released the unsafe vehicle to me after selling only a spark plug replacement. On sept 26, when I attempted to pick up the vehicle, the check engine light was flashing immediately at handover. I refused to take the unsafe vehicle. The dealer then replaced an oil control valve (ocv) and released the vehicle to me again later that day. After this second "repair," I drove the vehicle for only a few miles before the engine failed again with a check engine light. The dealer has since admitted in writing (bbb complaint #xxx) that the engine was "deprived of lubrication" due to the initial low oil condition. By ignoring early warnings and releasing a vehicle with a dying engine twice, the dealer put me and other motorists at risk of a sudden loss of power at highway speeds. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

2022 kia Sorento under 86,000 miles is jerks intermittently but no codes are being shown. Currently at the dealership and tech suspects transmission, which has been reported by numerous consumers of this issue but the recall was only applied to certain kia Sorentos and it should be broader.

2022 kia Sorento lx started off with rpm acceleration randomly. It progress and started happening multiple times during a ride. Took it to jake sweeney kia dealership, they were not able to pick up on any codes. They said they tried a flight recording and couldn’t record data, but not even 15 minutes off the lot the symptoms proceeded. Now the vehicle is trying to shift gears while in drive. I’ve provided videos and the dealership responded back and said, “after speaking with my manager about this situation I can't really do too much until it becomes a constant issue. I know that isn't what you want to hear but at this time without a check engine light or it happening all the time there isn't much I can accomplish for you. ” not only is this a safety hazard for myself and my child this is negligence on kia and jake sweeney kia florence.

The vehicle is jerky, loss of power, jolts, and very high concern of safety while in use.

There is an electronic glitch with the gear shifting system where it will randomly / sporadically not allow shifting from reverse to drive and provides the error message "gear already selected. " this has happened numerous times and resolves itself after 1-2 minutes. However, the vehicle remains in the wrong gear (reverse) while waiting, creating a significant safety issue. I purchased this vehicle brand new from kia coughlin in dublin, OH. After two service visits where they were unable to recreate the problem (it happens randomly / sporatically), they have not provided resolution or a way ahead. I have multiple videos of this issue taken while it was happening.
