My car has this issue that when I am slowing down it will automatically shift to park and will not let me shift to drive until I turn the car off and on.

This puts not only me, but the person behind me at risk. I took the car to a mechanic and he stated that there was no recall for this issue but that I should contact you (NHTSA). The mechan…

The vehicle felt like it was all over the road at highway speeds. Took it to a mechanic and the rear subframe had become weakened with premature rust. The mounting point for one of the rear suspension arms had broken off of the subframe and was making contact with my gas tank. I called the dealer to see if there were any recalls. No recalls for this issue however there are a few reports on this website. I have also been on forums for my vehicle and it is a VERY common problem on these vehicles. From what i gather this is a widespread iss…
