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.

I have recently moved to Pennsylvania, a state with many hills, and have found that on icy hills, the traction control causes the engine to shut down entirely when the wheels slip. This creates a very dangerous situation where there is no power at all to the wheels, causing the car to slip backward on the ice. I live on a steep hill and my car has almost rolled off the hill three times due to the failure of the traction control / engine. The Prius, unlike many other cars with traction control, has no traction control shutdown/override switch. In researching this online, many other owners report the same problem. Toyota refuses to acknowledge that there is a problem. This is very dangerous.

I have a 2007 Toyota Prius that is approaching 36,000 miles soon. Its brakes stutter when I try to come to a smooth stop. Its engine also vibrates excessively as if its misfiring, when idling. The symptoms do not happen all the time, but they happen frequently. I have taken the car to the local dealership several times, but they have not been able to fix the problems permanently. After my most recent visit to the dealer, they claimed they could not replicate the brake stutter symptoms and that the car\'s computer had no record of it misfiring. If you do a google search on the internet about "2007 Prius brake stutter problems", it appears to have happened to many other people. Please help. I want the problem fixed, or the vehicle replaced. There has been no physical damage nor crashes nor injuries. However, I am concerned that such symptoms detract from the value of the automobile, or at worst may result in an actual crash and injuries later on. The symptoms are a distraction and annoyance while driving.

The contact owns a 2007 Toyota Prius. The contact stated that whenever the front wheels began to spin in icy or snowy conditions, the engine completely shut off. The failure occurred multiple times while trying to drive up a hill or an inclined driveway. The dealer inspected the fuel injection system on several occasions and was unable to find the cause of the failure. The manufacturer stated that the vehicle was designed in such a way that the engine would turn off to avoid damaging the stability control system. The vehicle has not been repaired. The current mileage was approximately 36,000. The failure mileage was approximately 2,000. Updated 3/16/10 updated 06/29/10

Indicator lights flashed. Malfunction indicator lamp stayed on. At 2,644 miles, 12 V. battery dead & replaced. I was told to keep the gas tank half or a quarter full or the reserve gas tank would cause the car to run on battery. The battery might have died because the car sat too long before it was sold/at 8,879 miles, I went in. After filling the gas tank & taking out the nozzle, gas spewed & bubbled out. The car stalled while driving slowly & while in park. Indicator lights flashed. The malfunction indicator lamp and master warning lights stayed on. It took 5 min. To turn off the car. I started the car. Those lights stayed on. I was told I left the "trunk door" open & ran down the battery. (not true.) there is a gasket around the access hole and if a person "is a little bit off, " the gas will regurgitate. (I was not " off" & did not top off the tank.) they reprogrammed the computer. The gas tank had not been filled so I knew they did not fill the gas tank and try to recreate the situation as they said they would. I bought gas at a different pump. I stopped at a stop light. I could feel a loss of power in the car. When I pushed the gas pedal, the car would not move. I turned the car off and on 3 times before it would move. It crept slowly through the intersection as the traffic signal turned red. I took the car in at 8,936 miles. I was told if my problem is associated with the battery that was taken out of my car, it is not at repair person's responsibility because he did not touch my battery. When a battery is disconnected for a certain amount of time, if something is not reset, it could cause problems. Then, he said no trouble found/my car stalled and/or had a loss of power. I took it in at 9,014 miles. No trouble found. I was told that my problems could have been caused by a faulty gas pump overfilling my tank. The gas station is new. The manager said the pumps were inspected. If there were a faulty pump, everyone would have problems.
