Example complaints

Visibility (wipers, defrost, mirrors): “This car was purchased in charlotte nc in winter of 2018. In november of 2019, while driving down the road with no cars in site, we heard a loud pop. We couldn't figure out what the noise was because it sounded like a rock hit the windshield but we didn't see anything. We couldn't figure out where a rock could have come from as their were no cars on the road. That afternoon we pulled back the roof screen to find that the glass panoramic roof had cracked all of the way back. The crack started in the upper left corner of the car in the curve of the top. …”

Air bags: “On july 15, 2020, I was involved in a one car accident. The car left the roadway on a curve when I lost consciousness due to a medical issue, and slid down an embankment into a tree. The tree prevented a total rollover and the car was at a 45 degree angle. I was thrown against the driver's side door and sustained injuries. The side airbags did not deploy, neither did the front airbags. The car was totaled. The side airbags are supposed to deploy in a side impact or rollover situation, both of which occurred. …”

Brakes: “Stopped in traffic on a slight downgrade for a long period of time. Brake pedal was applied firmly, when the truck in front of me would release the pedal slightly to allow the car to drift forward. After several times there were no breaks and the car drifted into the truck in front of us. Had car back to dealer 2 times they claim they can't find anything wrong with it.”
