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.

Daily driver of the vehicle for two years was easing into a parking space and applying the brakes when vehicle surged forward over a curb eventually crashing into a tree. After the vehicle went over the curb it went through a chain link fence and down a steep embankment leading to a great deal of chaos and confusion as to whether the brakes continued to be applied, but the driver Is confident that the brakes were being applied when the initial surge occurred. The driver's spouse experienced a similar event about a month earlier when driving about 2 mph down a long driveway. In this instance the engine revved to a higher speed when the brakes were applied but the brakes did stop the car before the engine speed returned to normal.

I was turning into a 10 feet deep strip parking lot and the Lexus IS250 (2010) I was driving suddenly accelerated and crashed into a parked car. I do not recall either stepping on the accelerator or the brake. The distance from turning into the parking lot and the car I hit was approximately 5 feet. I did not have time to react. The airbags opened and the front was massively damaged.

IS 250

  • 9,200 miles
I purchased a Lexus is350C on Feb 12, 2010. On July 29, 2010 with a little over 9,000 miles on the vehicle, I was getting on the freeway at whipple headed North on 101, I accelerated really hard to avoid oncoming traffic. When I let up on the accelerator the car lost power! I couldn't accelerate or keep up with traffic. The engine was running like there were several cylinders not working. The antiskid and check engine light came on. I drove to the hillsdale shopping center and parked the car. When I restarted the car it ran ok. I drove the car directly to the Lexus service department for a repair. The service department had the car for about a week but could not reproduce the problem. They returned the car to me with no solution to the problem. I am very concerned that this Is a serious safety problem with Lexus, Toyota Is sweeping under the carpet. I could have been killed if the other drivers had not been driving safely. When I spoke to Lexus corporate they stated there was nothing they could do.
