Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

The vehicle crashed into a rock. The air bags had not deployed. A police report was not filed and there were no injuries sustained. The vehicle was driven home.

Car was stationary in driveway car would not start and master warning light was on in addition to a warning saying "shift malfunction. When parking, park in flat place and apply parking brake securely" a buzzer was sounding. This indicates a shift control system error. The car would not start. Notified dealer and the car was towed. No error codes were found. The car started for the dealer.

This is an update to complaint number: 10809942. === I forgot to include this: *** besides the rolling backward problem I had, if one has a get-into-gear-and-go emergency, it is very likely that the car will not get into gear, you will not realize that, and when you step on the accelerator to go, the car will not move. Then you have to realize why it did not go and shift again. In case of an emergency, this delay may be critical.

The transmission gear shift is dangerously designed. The shifter will move into a gear positions even if it transmission does not actually shift into the gear. Whenever the handle is released, it springs back to the central position, whether the transmission is in gear or not, so the driver does not know if the transmissions is actually in gear or not--or if in gear, which gear. The driver is expected to look at the instrument panel so see what gear is highlighted in the display. I rented a Prius for a week and numerous times, I thought I had shifted into drive (or reverse), but when I pressed on the accelerator, nothing happened because it had not gone into the selected gear, and I did not know that because the shift lever always springs back to center position, whether the transmission is in gear or not. One time, at night, I was making a three-point U-turn, shifted into drive, turned the wheel to the left, stepped on the accelerator, and suddenly the car was turning to the right! panic'slam on the brakes. Then I realized the transmission had not shifted into drive and I was rolling backwards. If the driver feels the shift lever go into a gear, the car should be in that gear; if it does not go into that gear, then the shift lever should not move into the position; and once in gear, the shift lever should stay in position, not spring back to center.
