KIA Complaints

While driving approximately 70 mph on the highway returning from Door County, 20 miles north of Manitowoc, on a clear day with temperatures in the mid-to-upper 70s and no other vehicles nearby, the panoramic sunroof glass spontaneously shattered with a loud noise. The middle portion of the glass was sucked outward/up and away from the vehicle. The sunroof had not been used (or we are unsure if it was ever opened more than once or twice since acquiring the vehicle). Immediately afterward we heard significantly increased wind noise. We pulled over, went to a car wash, vacuumed all small glass pieces from the vehicle, and duct-taped around the inside seam to prevent any remaining shards from entering the cabin. The vehicle is only a few months old. No impact, debris, or external object was involved. Photos of the damaged roof and remaining frame have been uploaded.

The contact owns a 2012 Kia Sorento. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that the vehicle failed to exceed 20 MPH. There were several unknown warning lights illuminated, and the air bag warning light was also illuminated. The contact received notification of NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic). The vehicle was taken to the dealer, and the recall repair was performed. The failure reoccurred six months later. The vehicle was towed to the dealer. The contact was informed that the failure was caused by wiring issues with the front passenger's seat. The vehicle was not yet repaired. The vehicle was towed to an alternate dealer. The vehicle had not been diagnosed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 227,079.

On July 14, 2026, the vehicle's engine was replaced by an authorized dealership under an official Kia recall. On August 16, 2026, while driving on the highway, heavy smoke suddenly began emitting from the engine compartment. When attempting to slow down, the braking system suffered a total loss of power and failed completely. To stop the vehicle, it had to be steered into the highway median to intentionally scrape against it to force a stop. Immediately upon exiting the vehicle, heavy flames were observed under the engine compartment before completely engulfing the front of the car. The fire department extinguished the fire, and the vehicle is a total loss.

The contact owns a 2012 Kia Optima. The contact stated that while idling or while driving, the message "Hybrid Warning System - Check Brake - Stop Driving Immediately" was intermittently displayed. The contact stated that while driving and depressing the brake pedal, the vehicle failed to respond as intended, causing the braking distance to become extended. The vehicle was taken to the dealer, where the contact was informed that the vehicle could not be diagnosed because the message was no longer displayed. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Car has been degrading and fully depleting batteries, one per year, since car was purchased new. Some undiagnosed electrical drain is resulting the car not starting, either at home or at a stoplight when 'auto-stop' causes the car to stop and restart in traffic. Vehicle has been to dealership to investigate a cause 4 times without a conclusive finding for the cause of the draw. Short battery life and repeated battery failure, paraticularly when the car will not re-start at traffic light stops, is a safety hazard for users of the vehicle. More detail available upon request.

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.

The brakes failed; they felt spongy, as if my foot were pressing directly against the road. The car accelerated and I headed toward a wall; the sensors didn't stop the vehicle. It came to a halt against the wall after the impact. I was on my way to the repair shop for a scheduled appointment due to electrical problems.

The transmission pump on my transmission just went out randomly last week. The power in my car went into limp mode and the car won't drive properly now. The car was being driven at the time this happened, and my husband had to pull over, as the car wouldn't work. I had this looked at by an auto body shop and they diagnosed it with this, which is to be found that there is a recall on my specific year and model of car for this issue as well. For about a month prior, we had noticed a few "stutters" when driving the car. After I hit 100k miles on the car, it was doing it almost daily.

I charged my car at a level 3 fast charger on a road trip. After completing my charge, the AC stopped working. The fan worked but it was only blowing hot air. Normally this would be a nuisance, but the day was about 114 degrees and the car’s interior was probably close to 140 degrees. I was driving on the interstate so it was very hard to keep the windows down. The lack of HVAC made the car difficult to operate and if my family was in there would have been a safety hazard. I took it to the dealer who initially thought it need the coolant to be recharged. It turns out that the inverter for the A/C died. Apparently this has some connection to the known issues with the ICCU, which in my case just blew out and was replaced a month and a half prior to this incident.

ICCU failure. I charged overnight at my home L2 charging as usual. I backed out of my garage and heard a loud pop. Almost immediately an “check electrical” warning came up. The car went to turtle mode and then completely died. The car was towed and I was informed the ICCU needed to be replaced. The car had all previous checks on ICCU performed (per mailed recalls) and was updated and passed each time.
