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. When rolling to a stop, I've had a few instances where the car shifts to park and the car behind me almost hits me due to the car shifting on its own and not allowing me to proceed with the flow of traffic. 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 mechanic stated that the component that might be failing is the electrical ignition switch, basically telling the car that there is no key in the ignition. There are no warning lights or any other indication. This has happened to me a multiple times. When this happens, since I am not at a complete stop, it shifts to park and grinds my transmission. This causes the car to abruptly stop without having my foot on the brake to warn the drivers behind me.
The air suspension intermittently drops the car, resulting in a warning light that says car too low, pull over. You have to stop the car wherever it happens immediately as the car is so low it rubs the wheels on the wheel wells. I've had to stop on the side of two different freeways and up in the mountains when it was 10 degrees outside. It will usually raise back up if you turn the car off and on several times, but sometimes it may take much longer for it to raise back up. Sometimes when I come out in the morning the car has lowered as well.
Airmatic suspension failure. Car has excessive lowering after overnight period of sitting and uneven ride.
