Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“While driving home my vehicle began to smoke and leave fumes within the car. I pulled the vehicle immediately to inspect to find that my kickplate was on fire from below the kickplate. I pulled the panel off and doused out the flame. Now with the vehicle home I do not feel safe driving this vehicle knowing something like this is even remotely possible.”

“I was driving home from work tuesday evening, then I noticed my head lights flicker twice. I thought nothing of it then they suddenly shut off. I flipped the switch back and forth until it turned on. Then 5 minutes into the drive they completely shut off again but this time they never came back on. I had to drive 10 minutes to my house with my hazards. I got pulled over but luckily my brother is a cop and I was able to provide his gold card and got a pass from a ticket. The next day I checked all the relays and fuses in the car hoping one had burnt out, but that was a negative. …”

“There’s something drawing the battery AMPS down. This has been an ongoing problem for the last 6 months. Per Kia techs, it was my battery and grounds needed cleaning. Battery changed, techs cleaned all the grounds the problem still exists. I was informed that it was the alternator, new alternator installed. Problem still remains. A new starter installed, problem still exists.”

“Kia has issued a partial recall, NHTSA Recall Number 23V652000, but has still not established a remedy so that dealers can alleviate the problem. The current recommendation is to not park my car in a garage or near other objects. So, it is a potentially dangerous situation and the delay in Kia's finding a remedy is unacceptable. I have contacted two dealers and their hands are tied until they are told what to do.”

“My entire Dash went Black. I could not see speed, gas level, milage. This is an extreme Hazard! I brought the car into Crown KIA in Clearwater to run a Diagnostic Check for 0.5 hour at $150 and they could not find the problem. I had no money to pay for additional time! I did research on this and found that this is a common problem with KIA's no matter what year!! Just because my particular VIN # is not on the recall should not absolve KIA from their duty to provide a safe reliable car!”
