Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Engine oil consumption: more than 1 quarter every 1,000 miles but the mechanic did not find any leaking. The vehicle has total 55,000 miles and I drive about 1000 miles/month on freeway and local streets. I also found many reports on the websites and many Hyundai dealers had tested the oil consumption and waiting to the response from Hyundai headquarters.”
NHTSA complaint #11322288, filed 2020-04, 50,000 miles“While I was traveling along a rural road at approximately 40 MPH my car engine shut off abruptly and without warning. There was no pull off and I was left on the road in the flow of traffic. The car will not start and had to get towed back to my place of residence. Checked for error codes but none were found.”
NHTSA complaint #11292469, filed 2020-01, 78,322 miles“I was sitting still at a traffic light at a very busy intersection and the car just turned off and wouldn't turn back on. I just sat there trying to get it to start but no go. Meanwhile cars were whizzing by me and I was afraid I'd get hit if I got out. After almost 20 minutes I was able to get the car started.”
NHTSA complaint #11221889, filed 2019-06, 85,020 miles“Wind deflector previously fixed twice before via recalls came loose again. I was on the interstate with the sunroof open. Had to hold it down to prevent damage until I could get off the freeway safely. Had to manually hold it down as I closed the roof while outside of the car.”
NHTSA complaint #11328681, filed 2020-06, 109,000 miles“I was admitted into the hospital, where I had surgery and was told I had a hemorrhagic stroke. October 2015, I had 2 more strokes and surgeries. I never had a history of strokes, and was wondering could this be a part of an environmental issue with the chemical exposure from the new vehicle? Any useful information would be greatly appreciate.”
