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.

I was on my way to work when the vehicle in front of me came to a complete stop. I was approx. Three car lengths behind her (which is plenty of distance at 25mph) when I applied my brakes though nothing happened. They made a grinding noise (like the pads were gone, but they are new ceramic pads). I ended up hitting the vehicle in front of me. I got a citation for following to close, which is $260, my insurance was increased by over $100 a month, I had to pay for her car plus $3750 of damage on mine. She didn't have insurance and was driving on a suspended license.when I told the officer what had happened with my car he just looked at me as if I was stupid. This is a major problem that is and has cost people a lot of money, not to mention being without a vehicle.

As I was driving down the highway I accelerated to pass and it seemed as if my throttle shorted out. My car's RPM's dropped and I started to decrease speed. I removed my foot from the accelerator and it seemed to catch again, but as I pushed the pedal again my accelerator went out for a second time. At this point and my engine shut down. I shifted into neutral and tried to restart my car multiple times while rolling with no success. I had to try to maneuver my car through traffic with no power, rolling at a speed of about 40 miles per hour and decreasing rapidly while on the highway with a speed limit of 65. After I made my way over two lanes to the shoulder I tried to restart my car and it would catch and then turn off. I waited a few minutes and tried again, it started as if nothing had happened and I continued on. I could not take my car to the shop but planned to take it the next Monday. On my way home on a Sunday evening I was driving on one of the busiest streets in arlington, tx and the car started to shut down on me again. I pulled over and turned the vehicle off and waited a few minutes as I have done before and headed home. As I was driving again the car's throttle went out completely and I could do nothing except roll down the street. As I pushed the throttle my car would not exceed 2,000 RPM's and the max speed was 25 mph. I made it to a safe spot after rolling for about 2 miles at 12-20 mph on a 45 mph road. I had to wait until Monday before I could have someone tow it away. The salesman and I did the research on the Scion Tc and assured me before purchasing the car, that acceleration was not a problem. I was concerned due to the problems Toyota was having however I did not see any recalls or major problems except airbags, windows, and the sunroof recalls. I was expecting a great car, with great safety features and durability but issues with a throttle body going out while on the highway is a major concern that needs to be investigated.

Occasionally while stopped at red light, my engine will rev unexpectedly without my me touching the gas pedal, this has caused my car to jerk forward on several occasions and has almost made me hit the car in front of me and worst it has forced me into the middle of intersections.

The contact owns a 2005 Toyota Scion. The contact stated as she started the vehicle it accelerated and would not stop as she depressed the brakes the vehicle finally stopped. The vehicle was towed to a mechanic. After a diagnostic test they stated that they could not repair the failure and the vehicle should go to the Toyota dealer for repair. The vehicle was then towed to the dealer and after running a diagnostic test it showed that the actuator needed to be replaced. The repair cost was $1,000 and the contact wants a reimbursement since her model should be recalled but it does not appear on the recall list. The Toyota manufacturer could not be reached and this has been going on for over a month. The failure mileage was 47,574.
