Example complaints

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

“I've had my car for less than 2 years and the battery completely drained/dead. Hyundai refuses to cover it under the 3 year warranty due to my car having over 36k miles. The car was brand new when I purchased it and I've never had a car battery died so fast ever in my life. Also, sometimes the backup camera won't turn off and will stay on even after driving frond for more than 10 minutes. It will only turn back off if I turn the car completely off and then back on again.”

“The system that malfunctioned was the brake light(s) and/or electrical components which started a fire in the trunk of my car on 2 separate occasions. On one of the occasions, the top break light in my trunk apparently blew out without my knowledge, it wasn't until my two kids in the backseat started to smell smoke that I pulled over and tried to figure out where the smoke was coming from. When I opened my trunk, I noticed the top break light had burned through the encasement and the wiring was dangling in my trunk which caught a plastic bag on fire. …”

“My 2018 Hyundai Accent caught fire in motion on the way to get gas on June 21, 2021. The car had no recalls and no electrical issues prior to the explosion. Fire department ruled the accident as electrical, I had the vehicle for 6 months. A loud explosion sound came from the hood, it started smoking and we pulled the car off the road, moments later it caught fire and created an explosion spreading from the hood to the back of the car. Because i dont have a car, I had temporarily close my small online business, this has been a nightmare.”
