What owners report
On August 17, 2025 I rearended a vehicle in front of me who jammed on their brakes for no apparent reason. We were the only two vehicles in the area. Upon impact, the following airbags deployed....steering wheel, driver knee airbag. I sustained injuries to my lower extremities from the exploded knee airbag which contained metal components that impaled my skin. I continue to receive treatment for multiple injuries and the wounds that have not healed. My safety was at risk due to the metal components (shrapnel) deployed via the exploded knee airbag. I also sustained injuries my left wrist from the steering wheel airbag, and my left chest from the tightening of the seatbelt. The local M

Driveshaft broke, peeling rims
The seats on both the passenger and driver size has split at the seams. They began to appear in 2012. The battery failed and the car would not start. Periodically the car starts up slow. The car bucks in a hard motion when trying to accelerate. The car makes a grinding noise, with a dragging feeling, while driving. Mechanics cannot figure out what or where the sound and feeling is coming from.
