KIA Complaints

My 2017 Kia Sorento has developed intermittent safety-related engine issues that have resulted in loss of acceleration and stalling. December 2024: After a two-hour drive, the vehicle stalled and would not restart. Roadside assistance confirmed the engine oil level was low, despite no external leaks. After approximately two hours, the vehicle restarted. [XXX]: After driving about 30 minutes and parking for 10–20 minutes, the engine started with loud rumbling/knocking noises, and the accelerator was unresponsive. The problem resolved only after shutting the car off and restarting. Video is available. The Kia dealer performed a rod bearing test which passed, but the symptoms match early failure stages of the known Theta II engine defect covered under Kia’s lifetime warranty (PI1802 settlement). Kia attributes the issue to “low oil” as a maintenance problem, but the oil consumption appears to be internal and abnormal. This defect creates a serious safety risk because it causes sudden loss of power, which could lead to an accident if it occurs while driving in traffic.

When traveling on the highway, the vehicle would not shift into a higher gear limiting the control of the vehicle to accelerate to the flow of traffic. The transmission would not shift for approximately 1/4 of a mile and was stuck at a max speed of ~35 mph and it would not accelerate. This loss of control almost caused an accident and put my family and self at extreme risk. Eventually the vehicle did finally shift gears allowing us to accelerate with the flow of traffic (60mph) This issue with a delay in shifting gears has intermittently happened on prior occasion when accelerating from a full stop, however, this was the first time it happened at an accelerated speed. The vehicle is not safe to operate and was towed to a service center; however, the issue is intermittent and not easily reproducible -- making it even more dangerous as you do not know when it will happen next.

My car lost power on [xxx]..Called a tow truck to come and pick it up. cone to found out my engine was blown. Taking it to a kia dealership on 09/12/2025 to get a diagnostic test done on it. I have all my paperwork. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 Kia Telluride. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The contact stated that the check engine warning light had previously illuminated; however, the warning light then turned off independently. The vehicle was taken to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 63,000.

VIN# [XXX] My recall has not been repaired because Kia claims the repair parts have not been made available to them yet. This recall is from Sept. 2023. Why hasn't this been taken care of yet? Ridiculous & DANGEROUS!! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2021 Kia Forte VIN# [XXX] 107,000 miles While driving my Kia Forte on [XXX] i experienced a sudden noise without warning just 2 months to the exact date after an oil change. The vehicle became unsafe to operate and could not accelerate properly. In some cases it would no have it would feel like it was losing power and creating a scary and dangerous situation. A certified mechanic diagnosed there was no oil in my vehicle which matches the oil consumption defect identified in Kia's Theta II GDI engine recalls and nationwide class action settlement. Kia has acknowledged in public filing that is defect poses a risk of engine seizing and fire. Although my VIN is not currently listed under any active recall, my vehicle exhibits the exact same defect pattern as recalled vehicles, including sudden loss of power at highway speeds which is a significant safety hazard. Manufactures Response: I contacted Kia Corporate to request an engine replacement consistent with the recall and the settlement remedies and they refused to cover the repair solely because my VIN is not included in the recall list despite the defect being identical. Safety Concern: The sudden loss of power creates a risk of rear-end collisions, loss of control and potential fire. This defect can be life threatening and should not be excluded from recall coverage simply due to VIN range. Requested Action: I am requesting that NHTSA investigate why vehicles with identical engine defects, including mine have been excluded from recall coverage and compel Kia to provide a no-cost repair.

While driving at random times, there is no acceleration while pressing the gas pedal. The battery shows low charge and gradually goes down instead of up. Sometimes the “check hybrid system stop safely” warning light comes on. Our safety was put at risk because it has happened while trying to merge on to the freeway or when there is no shoulder or area to stop safely. Since we can only glide no more than 30 mph we can easily cause an accident if we are not able to exit the road safely. We have taken the van in for inspection to two different Kia dealers and they are not able to find anything wrong. We were stranded 2 hours from home and had to take an uber because the van would not accelerate fast enough to drive on the freeway. The check hybrid system light has turned on at least 3 times but the dealership says there is no record of any warning lights turning on. We took a picture of the light while it was on the last time. This problem has occurred over 8 times putting our lives at risk.

Power train incident - • transmission holding gears, jerking between shifts, gear shifted into S mode on its own and stuck there, unresponsive acceleration, locked up steering/inability to turn the steering wheel and total loss of drive power. • happened while merging onto a highway in one of two split lanes for highway access. A merging semi truck in the other merging lane almost ran into me because I could not give it gas. Me and a local police officer who saw me broke down and stopped to provide additional cover, were nearly hit several (6) times from other vehicles and semi trucks due to malfunctions happening. • diagnosed by Kia dealership and was told there was a major electrical failure which caused the electrical oil pump to fail and need a new transmission. Although my VIN doesn’t list recalls, similar issue to the recall on my same year/make/model under NHTSA Campaign Number 21V519. • Warning lamps/messages shown in photos attached. __________________________________ Forward Collision warning incident - • front forward safety system light appeared on dash, then moments later a warning appeared and the vehicle braked on its own detecting a vehicle in front of me when there was not another vehicle in front of me within vision!! • happened while driving in a 55mph zone, a vehicle was driving behind me when this occurred and that vehicle almost slammed into the back end of mine causing a crash. • problem not yet inspected on vehicle due to blown transmission from above incident and inability to start/move the vehicle.

Engine started running rough, took it to a shop and was told that oil has been going through the exhaust and has clogged up the catalytic converter. Advised the engine must be replaced. Contacted a second shop and was told the same thing. Have been advised this is the same failure as the current recall for 2021 to 2023 but ours is 2015 and isn’t covered. Looking for guidance. Thank you.

Parking lights stay on, change brake light switch but the hole that the switch goes in is not aligned with the brake stopper to turn off the stop brakes, therefore it remains on. Battery needs to be unplugged to keep from draining. The mechanism to stop the lights from remaining on is somehow shifted to no longer turn off the brake lights.
