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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

When braking while the vehicle is going over a bump or depression in the ground, the vehicle lurches forward. Instead of stopping the vehicle seems to accelerate forward. This happens consistently in this setting.

Excessive oil consumption. Recently I notice oil pressure low light lights frequently. It used the oil was changed every time the maintenance light come up. About every 5000 miles. Now the low oil pressure comes almost every 1000 miles. The car only has 89K miles.

The contact owns a 2011 Toyota Prius. The contact stated that while driving approximately 75 mph, the vehicle would independently shift from drive into neutral after driving for a long distance. The contact restarted the vehicle and it resumed normal function. The vehicle was taken to the dealer. The technician diagnosed that the accelerator pedal and the brake pedal were depressed simultaneously, sending the vehicle into automatic override. The manufacturer was not notified of the failure. The approximate failure mileage was 20,000. Updated 5/5/15

My 2011 Prius II intermittently goes into reverse when I shift into drive. Approximately 10 times now since beginning. Twice it has gone into drive when I have shifted into reverse.
