“My car is a Hyundai sonata hybrid (non plug in) 2020. the issue I have is that when the car transitions from electric motor to the gas engine there can be a small delay resulting in the car not picking up and causing me to almost get hit in different scenarios. (I have not had this checked with a mechanic, Also there was no warning signs from the car indicating that there was a issue)”
NHTSA complaint #11490241, filed 2022-10“My car's battery dies 2 or 3 times every week. I have to enter into the the car with the manual key that is inside the key fob then hit the 12v rest button to start my car. I have been to two Hyundai dealerships and they both tell me nothing is wrong. I just picked it up a week a go and it has died twice since I picked up. I see many complaints on reddit about the same issue, even some with car dying while driving. This is a serious that Hyundai needs to figure out.”
NHTSA complaint #11555368, filed 2023-11“I have a 2020 Hyundai Sonata limited, recently at 68,089 miles on the odometer my wife was driving and got an engine overheat light and noticed thick white smoke puffing out the exhaust pipe. I told her to pull over when she called me and have it towed to the dealer. Soon after I went to the dealer to look at it because they were saying it would be weeks before they could look at it, and I noticed the coolant reservoir was empty. So, I filled up the reservoir and took it home. …”
