KIA Complaints

My 2021 Kia Seltos (manufactured April 2020, ~94,000 miles) has the 2.0L Nu MPI engine affected by a known piston oil ring defect. Symptoms include piston noise, excessive oil consumption, rough idle, reduced power, and codes: P1327 (PNSS-detected knock), P0304 (cyl 4 misfire), P0017 (crank/cam correlation error). These indicate progressive cylinder wall scoring from improperly heat-treated rings, risking seizure or fire. Service history shows: • SC209 (Safety Recall 21V-259) inspection in Jul 2021. • SC209A (PNSS software update) in Feb 2022—explains why P1327 now triggers. • Other campaigns: anti-theft (CS2309/CS2312), AWD ECU (SC242/SC297), ECM logic (SA463). The defect progressed despite early recall work; dealers deny full engine replacement, citing prior completion or shifting coverage. SC209 has no mileage limit—progressive damage qualifies for re-inspection (vibration test, bore scope, compression) and free long block replacement if confirmed. You’ve faced loaner return demands before 2-week period, goodwill denials, and inconsistent coverage. The issue aligns with NHTSA concerns (e.g., AQ25001 on similar recall effectiveness).

While actively parking, my car accelerated and slammed into a wall an arm's length away. The collision was impactful enough to cause my seatbelt to engage and slam into my sternum. While attempting to turn off the car, the computer system glitched, engaging all three different drive modes (N, R, D). The breaking command I gave the vehicle was ignored, and the vehicle accelerated into the parking garage wall. No front collision assist or safety feature engaged. The vehicle is currently at a repair shop with the damage cost totalling $17K. The MFR recently inspected the car in Decemeber when the lease expired and I purchased the vehicle. Prior to that in October, the car came to a full stop and turned off on the highway.

The contact owns a 2014 Kia Sedona. The contact stated that while driving in sunlight, the contact became aware of bubbles on the windshield, causing blurred vision while driving. The dealer was notified of the failure, but the vehicle was not inspected. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 127,000.

The contact owns a 2013 Kia Optima. The contact stated that while his wife was driving approximately 55 MPH, the vehicle stalled but restarted. The check engine warning light was illuminated. The contact stated that the failure was related to TSB: PI2002 / PI2002A. The contact discovered there was an issue with the damage to the connecting rod bearing. The vehicle was taken to an independent mechanic who determined that the battery needed to be replaced. There was an abnormal sound when the vehicle was started. The contact stated that there were metal shavings in the oil and the control valve. The vehicle was towed to the local dealer, where a broken valve and lifter were found, and the dealer determined that the engine needed to be disassembled. The dealer stated that there were metal shavings in the oil and the control valve. The vehicle was not repaired. The manufacturer was contacted and confirmed that there was no repair under recall for the failure. Additionally, the manufacturer requested the oil change records. The failure mileage was approximately 200,776.

The vehicle experiences a sudden and complete loss of power while driving. Specifically, the vehicle loses the ability to accelerate. During these incidents, the battery indicator shows critically low battery levels despite there being sufficient gasoline in the vehicle. The exact component causing the malfunction has not been identified by the dealership, as they report no diagnostic codes are present. The vehicle is available for inspection upon request. This issue has occurred multiple times while driving on highways at speeds where surrounding traffic is traveling approximately 55 mph or higher. This has also happened while pulling out into traffic, causing near misses of an accident. When the malfunction occurs, the vehicle rapidly loses acceleration capability and slows down to approximately 20 mph. This creates a dangerous speed differential between my vehicle and surrounding traffic. It becomes extremely difficult to safely maneuver into the breakdown lane due to the inability to accelerate. This situation creates a significant risk of rear-end collision or multi-vehicle accident. The dealership has been unable to reproduce the issue during service visits. However, the vehicle has been brought in multiple times for this same concern. The dealership has stated that no diagnostic trouble codes are stored, and therefore they cannot identify or repair the root cause. I have multiple videos documenting the issue occurring while driving. The vehicle has been inspected multiple times by the authorized Kia dealership service department. This issue has been occurring since July of 2025. Video Link: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Shifter Lock is engaged and would not shift from park unless I bypass the lock by pressing the release. It was a recall item, I had it replaced, but if failed a few days later. I called the dealership, I told them about the problem. They told me they replaced it and I could bring it in for a $200 diagnoses fee, but it would not be covered as it was replaced already. I was made to feel like I was the one that was causing it to fail. I have the paperwork but am not sure on the accurate date.

ICCU unit lost power and the car was unable to drive. Luckily I was parked when it happened but if I had been driving it would have been very dangerous. The part was replaced under warranty but they said it could happen again which really scares me.

The contact owns a 2023 Kia Sorento. The contact stated that while his wife was driving 10 MPH, after making a left turn, the sunroof shattered with the sunroof cover closed. The vehicle was steered to the side of the road and inspected, but the contact was unaware that the sunroof had exploded. The vehicle was taken to the residence, where the contact’s husband became aware that the sunroof had shattered. The contact had not sustained any injuries. The vehicle was then taken to a dealer, where it was diagnosed that the sunroof had exploded and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was approximately 39,000.

After having my information panel replaced apx. a month later the airbag for passenger seat illuminated and has not gone off.

The paint is peeling off the roof and front of vehicle. The car is (2019) out of the 3\36 warranty and the dealer says there is nothing they can do to help me. I asked the service writer if this is a common problem with these vehicles. His comment was what color is your car (it is white) he said the white cars are having a major problem with paint peeling.
