What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
One night shortly after I picked up my 2020 genesis g90, I was driving home on a city street when I noticed something wrong with my headlights. As I was driving I was trying to figure out what was wrong with them.
I have experienced stability issues with multiple Genesis & Hyundai's. I will send details once I have an ID Number. I have experienced everyone of of these complaints that are currently on your website.
The continental contriprocontact tires on my 2020 genesis g90 have a constant vibration. It feels like you are driving over rumble strips. On 2/12/2020 (1 week after purchase), called the dealer to report the problem. The dealer said they talked to genesis and genesis said they had no knowledge of a tire problem.
