KIA Complaints

The vehicle was being driven on a highway when it became unresponsive to input from the accelerator pedal and the car's dashboard indicated an electrical system failure. There were no indications of problems with the car before the electrical system failure warning appeared. The car coasted to a stop on the side of the highway, where it was disabled (i.e., it would not shift into drive or reverse). The car was towed to a Kia dealership, where it has been for more than five weeks. The dealership replaced the ICCU but that did not resolve the problem and the car remains non-functional. The Kia dealership is waiting for the delivery of additional backordered electrical system parts to see if they resolve the problems.

Adding to NHTSA Safety Issue ID # 11685509. The car was taken back to the dealership on 9/8/2025 and the maintenance department was showed were the Junction box that controls a lot of safety features could be the issue and why normal diagnostics tools used could not isolated the issue to it. Online research shows that this Junction box is a common issue and an undiagnosed issue with major safety issues. Actually the maintenance department had no clue as to were it was even located on a 2019 KIA Sonata. Please look into this issue. I am having mine replaced but it will take a week to do it. It maybe because of the unavailability because of quality fixing the issue.

Sluggish acceleration, after I got an oil change a few weeks ago. No warning lights whatsoever, I’m thinking it’s the transmission , taking awhile to speed up especially on highway

Low beam headlights would work and some times not work and then one day they stopped working completely. We've had everything checked out and there is no explanation as to why this is happening. Replaced headlights, relays, and checked wiring.

My car has stop many times in highway running 55mph or 30 mph. It will completely stop my car has almost 15000 miles a 2021 kia seltos. I turned in my car to the kia dealershop to get check and they diagnosed a lot for so many things and have me pay to replaced the car’s battery. I had my 3year olf child when that happened The dealer just pushed it that it was the battery but its not. My car has only 15000 miles. they also ordered a pad crash main even whwn there was no accident happened. It is a critical safety of my component. For a very low milage car that has so many problem i think this is not good. The engine will stop when i pressed the brake and automatically refresed all warnings will show mainly engine light. it wont turn on when i pressed the button. It happen many times

The contact owned a 2013 Kia Optima. The contact's son was driving at 35 MPH when smoke was emitting from under the hood. The contact's son pulled over to the side of the road and immediately exited the vehicle. The contact's son opened the hood, and smoke was emitting from the engine. No warning lights were illuminated. The contact's son did not sustain any injuries. The police or fire department was not called. The vehicle was towed to an independent mechanic, who diagnosed that an electrical fire had started in the engine and damaged the engine. The vehicle was not repaired. The manufacturer was not notified of the fire. The contact stated that the engine was replaced in 2018 or 2019 due to an unknown recall. The contact did not notify her insurance company. The failure mileage was approximately 190,000.

We own a 2021 Kia Telluride which we bought new, have changed the oil as expected and had the 100,000 mile check completed. It now has about 116,000 miles and has been a great and safe car, until now. On a random trip home, traveling on a busy highway, we had to pull over because we suddenly lost power. Our children were in the car and this was very dangerous on a very busy highway. We had it towed to our local garage and was told it was down 3-4 quarts of oil which wrecked the engine and we would need a new one! There were no warning lights for the engine or the oil at all. We are currently having the engine replaced at our very hefty expense as we have no other choice. I see this is quickly becoming an issue with the 21 Telluride and I hope that Kia will do something about it!

My problem is with the headlights, in that the condenser lens for the low beam lights has clouded so badly that driving at night has become so dangerous. I have changed the bulbs twice in an effort to correct the problem to no avail. And with the sealed unit not able to be disassembled to clean the lens, my only option is to replace the units at approximately $800 each. This condition in my opinion should not have occurred.

Brakes failed with unintened acceleration. We were stopped behind a truck at a stoplight when the the vehicle accelerated with a foot on the brake. We had it towed from the scene of the accident to our local dealership for testing. They had the vehicle for 4 weeks. Kia customer care was not responsive to our calls and emails or the dealerships. The dealership could not confirm the cause without their cooperation. The police were called to the scene of the accident and there is a report. The vehicle has been looked over by the service department at our local Kia lot. It was appraised for cost of damages by the collision center.

The contact owns a 2018 Kia Stinger. The contact stated that while driving at various speeds, the vehicle hesitated and jerked abnormally while accelerating.

The contact was informed of the NHTSA Campaign Number: 23V634000 (FUEL SYSTEM, GASOLINE). The contact was informed that parts were not yet available. The failure mileage was 115,000.
