NHTSA complaint #11301083, filed 2020-01, 85,000 miles“First in line while stopped at a left-turn light on a city street. Light turned green, began to accelerate. Mid-way through the turn, heard a pop , lost steering control, and the rear end spun car into the curb. Keep in mind this is a 4-wheel-drive car. When the car came to a stop, the nose of the car was resting on the front passenger tire and wheel. The right-rear wheel was scratched and abraded all around because it was still spinning when it hit the curb. The front right wheel has damage only on half of it because it stopped spinning when the nose dropped onto it. …”

Luckily I was able to push my car to the exit and get off of the freeway to wait for the flatbed to pick me up. It is available to be inspected it’s just parked until I can get it fixed, the part is $1800 and I have not been able to afford it. I had a mechanic come and look at it and I was told what part it is. …”
