Example complaints

Engine: “I went to work at 5 in the morning, I turned the heater for the first time after last winter. I noticed that the heater was struggling to warm the cabin. After 10 minutes driven I got an overheating alert on the dashboard. I pulled over on the freeway shoulder and it started to notice a lot of steam coming from the exhaust and a really strong coolant smell. …”

NHTSA complaint #11549170, filed 2023-10

Electrical system: “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

Other or unknown: “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

Fuel system: “On July 15th I was driving away from work and my car suddenly stopped accelerating. I was able to get it towed to a body shop I previously had it repaired at. They said the battery system was blowing a fuse when it would become undrivable. They took it to the local Hyundai dealership where they applied a new software update related to the battery management system. This did not solve the issue, it continues to stop while in traffic and the dealership refuses to do anything to figure out the cause.”
