KIA Complaints

While driving on the interstate at 70 miles an hour on cruise, I turned off cruise control in order to take control of my vehicle in order to change lanes and my car immediately took back the control and accelerated and then abruptly hit brakes at 70 miles an hour throwing me forward hitting my head which caused unconsciousness and when I came to, My air bags had deployed and my car was total lossed. Due to the state of shock and a concussion, I thought the car had hit an eighteen wheeler which was the last thing I remembered seeing in front of me due to the damages to my car. However, the truck was not there and my car was against the wall where it had stopped. I don’t know if something like debris came from under the truck that was in front of me causing the sensors to engage due to the abrupt stop causing me to hit my head and knocking me on conscious. No other vehicle was at the scene and my car had significant damage causing it to be a total loss.

While driving on a sunny day on a 35mph road, my dashboard reported “Check Electrical Vehicle System”. A red battery symbol appeared and my cruise control disengaged with a message “requirements not met”. When I got home I read my 12 volt battery monitor that reported the battery was 11.99v and only had a 60% state of charge. Just prior to this short drive from home, my battery was 12.77v and had a 100% state of charge. I put in my ODB reader and it provided two error codes: P1A9096 and P1A961C. The first error code is the result of an ICCU failure in its DC to DC circuit (the one that charges the 12V battery from traction battery). Using a battery charger, I was able to fully recharge the 12volt battery. My monitor says that it’s healthy with 100% state of charge. Turning the car back on resulted in a rapid drain of the battery from 100% to 93% in just five minutes while parked. The electrical system failure warning lights are still lit. I’m having my car towed for repair. If this failure had occurred more than 10 minutes from my home, I would’ve been stranded.

137,000 Miles, regular oil changes every 4,000 miles,even adding 2 quarts during the 4,000 miles it would still come up short by 1 quart. Started throwing p0018 timing code,high pressure fuel pump on front blew off the valve cover,Im assuming due to jumping out of timing,as the high pressure pump sits ontop of one of the Camshaft rollers. Engine started knocking and is now useless.

When driving the cluster screen goes black and remains black until like 24hours later when buttons on the screens reappear. When it happens the odometer reading, speed reading does not appear. This issue started happening when I passed 40000 miles on the vechile

My rear passenger side window would not go up or down & the motor would run when the button was pressed. That was in January 2026. Now April 2026, my driver's side rear window will not go up or down.

The contact owns a 2017 Kia Niro. The contact stated that while driving 60 MPH on the highway, the vehicle jolted and shook abnormally. The electrical system warning light illuminated, and the vehicle lost partial power. The engine and hybrid warning lights were illuminated. The vehicle was coasted off the roadway to a gas station. The vehicle was towed to the local dealer, where it was diagnosed with a blown high-voltage fuse. The vehicle was repaired with a higher voltage fuse. The manufacturer was contacted and opened a case. The approximate failure mileage was 101,000. The VIN was not available.

The contact owns a 2013 Kia Optima. The contact stated that while his son was driving approximately 35 MPH, there was an abnormal metal-on-metal sound coming from the vehicle, and the vehicle stalled. The contact drove out to the location and became aware that the oil and the battery warning lights were illuminated. The contact attempted to restart the vehicle, but the vehicle failed to restart, and the starter motor was smoking. The contact stated that prior to the engine failure, the starter motor had been replaced. The vehicle was towed to the independent mechanic who had recently replaced the starter motor. The mechanic diagnosed the vehicle and informed the contact that the engine had seized and needed to be replaced. The mechanic informed the contact that the VIN was included in NHTSA Campaign Number: 17V224000 (Engine and Engine Cooling). The contact called the local dealer and the manufacturer but was informed that the vehicle would not be repaired. The failure mileage was approximately 130,000.

Driving on the highway with no obstacles or vehicles in proximity, the sunroof spontaneously shattered. If we had the sunroof visor (slide cover) open to let in light, we would have been rained down on by thousands of glass shards while driving at highway speeds. Luckily for us, the cover acted as a barrier from the glass. This part of the sunroof is over both driver and passenger seats. The vehicle was driven to the dealership which was very close to the occurrence location and the dealership would not inspect vehicle but did do a work order stating that they would not cover exploding glass. Dealer stated that we needed to contact our insurance company but I have held off due to feeling like it would be a fraudulent claim of damage since it was not caused by an object striking our vehicle. We have documented 24 calls to case manager with Kia and no action or returned calls to date. (04/07/2026). On a call with the Kia 800 number, the customer representative acknowledged he had heard of numerous problems with the sunroofs exploding for no apparent reason. The vehicle had been parked inside our garage and not moved or driven since the incident waiting for someone to investigate or inspect our vehicle.

As I was driving on the turnpike the car engine literally just shut down on me! It could have caused a serious accident. This is the 3rd time when driving the car just stopped on its own on me! Gas tank full, oil good and battery good, but the engine is not! It gave me NO WARNING either. THIS SHOULD BE A RECALL. I could have been hit all 3 times! Family came to help and tried to jump it and it wouldn't start so I had to get it towed. Dates happened March 28, 31st and April 6, all 2026. Also the key fog lock is defective! It works when it wants too.

My Kia Sportage has developed a loud engine knocking noise, which I understand is a known issue with Kia engines. I am concerned that this indicates internal engine failure and could lead to sudden engine seizure while driving, creating a serious safety hazard. The dealership denied repair assistance due to lack of oil change records, but the issue appears consistent with widespread engine defects reported in similar vehicles. I am requesting investigation into this issue due to the safety risk it poses.
