Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was commuting. I gave my car regular oil changes and tune ups. Then the engine coils went out. The car would not go over forty. Replaced that. Heard funny noises coming from the engine. The car was at 70k at this point. The manufacturers warranty said to replace the timing belt at 110k. So I decided to hold off as that probably wasn't the problem and a manufacturer wouldn't lie to me as they are regulated by the government. Then I am driving and the car dies in the middle of a busy intersection. I get the car towed. …”
NHTSA complaint #10370509, filed 2010-12, 80 miles“While driving on a highway with cruise control active, I was unable to turn off the cruise control with the steering wheel control buttons. The cancel and set buttons had no effect when pressed. The car remained traveling at the set speed. Tapping on the brake pedal did cancel the cruise control.”
NHTSA complaint #11172999, filed 2019-01, 102,500 miles“The car was running fine until after a few hours of driving it just stopped running. This is the second time this has occurred. The engine RPM dropped to zero and the car coasted. After sitting for less than an hour the car started up again. I took it to the Kia dealer and they said, even though the car had less than 60,000 miles, they would have to diagnose the problem and charge us $200 to do so, and the electronic parts were not covered.”
NHTSA complaint #10470101, filed 2012-08, 51,000 miles“The contact owns a 2004 Kia Optima. The contact stated that the check engine light illuminated. The vehicle was taken to an authorized dealer where the contact was informed that the failure was a gas fume leak and the accelerator sensor needed to be replaced because it caused the vehicle to accelerate and decelerate without warning. The failure mileage was approximately 100,000. The current mileage was 129,548.”
