What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The check engine light came on in my car. I was waiting for the dealer to call me to fix it for the 3rd time. I was on my way home when every electrical option on the vehicle turned on- wipers, lights, dash lights, brake- which caused the car to brake- then it turned off and I had no brakes, the car had no steering,…
My vehicle will randomly have the check engine light come on, a service shifter light come on, and then lose the ability to steer. I have taken it to the dealership twice and told it was fixed. Now it is back at the dealership for the third time.
I recall turning the wheel and not getting any response…then jerking more out of fear which was to much and I ended up smashing into a guardrail. I had to leave it in Pennsylvania at a collision center for repairs. May 26 - Can repairs complete so I picked it up in PA and drove to Louisville. A 7hr trip took 2-days.
The back seat in my vehicle came off it's mounting points and partially exited the back window during a rear end accident. The seat was folded forward at the time so no one could have been sitting in it in that configuration but: - I don't have confidence that in the regular position it would have held in place with…

Trying to avoid a large dirt clump left in the road by the road maintenence crew I swerved to the left at 35 miles an hour and the esm/esc light came on and the jeep took over the car I could not apply the brakes or control the steering the speed did not deminish and the vehicle crossed an intersection rolling up an…
On the third try, the brakes failed again, causing an accident. My son was in the vehicle and kept asking why we were not slowing down and stopping. The vehicle did slow down, but not enough or in enough time.
When turning into a parking spot on an incline, I had slowed to start the turn. I then let off the brake a bit to be able to roll into the spot. The car then accellerated into the wall at the end of the spot damaging my bumper, scratching the car next to mine and also the wall I hit.
