Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Car has intermittent problem with acceleration. Will go into a fail safe mode, wont accelerate past 40-60 MPH. I have had very close call on multiple accidents due to the fact I am unable to accelerate. My car lost power and could not pick up speed at all. This is a major safety issue and the car dealership will not help me.”
NHTSA complaint #11093798, filed 2018-05, 2,200 miles“On june 29,2020 my 2018 Hyundai Elantra with only 40,000 had a engine fire and totaled my entire car that was parked and turned off inside of my garage”
NHTSA complaint #11339703, filed 2020-07, 40,000 miles“While driving my car it just stops. I have been complaining to the local dealership for 1 year and they keep turning me away. My battery was replaced and that is it. I was told I was exaggerating that this was not happening. Yesterday was different from the other times it stopped. My car stopped on a busy highway and I almost ran off the side of the rode a cliff because the wheel and brakes locked up. No one is taking this serious. As I am driving the car will just shut off. The local dealership advised me to drive even further to get it fixed. How is this safe? …”
NHTSA complaint #11414653, filed 2021-04, 44,500 miles“The low tire pressure warning lights came on as I was driving down the highway and my tire pressure was displayed as 14 PSI on my back left tire. I pulled over and looked at the tire and it didn't seem low. I plugged my portable tire air pump in and attached it to the tire, and the gauge on the pump said 36psi, which is what it is supposed to be at. I got back in my car and started driving, and the car said the PSI was back to 36psi. Sounds like this is a common problem and Hyundai needs to address it. I even took picture of the warning when it came on for proof.”
NHTSA complaint #11206926, filed 2019-05, 13,000 miles“Passenger seat air bag indicator flashes and warning sound indicates seat belt is not buckled when nobody is in the seat. When accelerating, there are multiple hesitations where the car feels like it is in park or neutral. After about 15-30 seconds, the car starts accelerating normally”
