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 was driving on a local country road at about 15-20 mph (having just come out of a sharp turn). When I stepped on the accelerator after the turn, it suddenly began to "gun", at which point I stepped on the brake and to my horror got no response. I kept my foot on the brake, but the accelerator continued to rev or gun horrifyingly and the car continued to speed up. At another sharp turn I went off the road and sideswiped a tree, drove through the bedroom of a house (in one wall and out the other) and finally stopped in another tree. After an hour of police, fire, and other emergency personnel attempting to extricate me from the car, they had to remove the roof of the car to get me out of the vehicle. I was airlifted to the nearest hospital with a trauma center, where I was diagnosed with a fractured sternum, three broken ribs, two fractured vertebrae, and a lacerated liver. I was in the hospital for three days, after which I was released with a custom-fitted back brace that I was required to wear for the next six weeks. Fortunately, I was not permanently injured, but I suffer back pain regularly as a result of the fractured vertebrae.

Please note that I have 2 Lexus is 350's and have filed complaint for one (ODI number 10315495). I am making complaint for my other is 350 since the recall applied to both. Lexus has not acted timely in determining and announcing a remedy for my vehicle in relation to the safety recall. I received a letter from Lexus usa in late 9/2009 or early 10/2009 advising me of a safety recall related to my vehicle. Recommendation from Lexus at the time was to remove driver side floor mat. Lexus letter documented that they would notify me as soon as a campaign remedy is available. It is now 5 months after notification of safety recall and according to phone conversation with my Lexus dealership service manager and Lexus usa customer service no campaign remedy for my vehicle has been determined by Lexus. These phone conversations were yesterday, 3/1/2010. Lexus has not acted timely in determining and announcing a remedy for my vehicle in relation to the safety recall.

Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6) approximately 1st week of January, 2010, auto demonstrated several periods of idling rough while stopped at traffic lights or stop signs. Beginning of 2nd week of January, 2010, I was driving my auto on a cold, dry day and stopped at stop sign and stopped at traffic light and auto demonstrated 2 episodes of unintended excessive acceleration lasting approximately 1-3 seconds, then immediately demonstrated approximately 30 seconds of unintended acceleration, and then resumed normal acceleration for 5-6 miles. The first episode of previous described acceleration issues, occurred after I had left my garage and drove for 1 mile. The second episode of previous described acceleration issues occurred after I had driven the auto for approximately 5-6 miles. On 01/13/2010, I took auto to dealer, for routine service and asked them to check acceleration issues that had recently occurred. Service tech no codes pending, current or in history. Sales manager said these issues could have been caused by my auto being parked in warm garage and then driving in cold weather. Note that my auto 2007 Lexus is 350 was on recall list and there was no driver floor mat in my auto at time of described acceleration issues. Lexus had advised me by letter to remove driver side floor mat. On 2/23/2010, I experienced identical acceleration issue as described previously. The weather was warmer than day of previous episode and roads were dry. I left my garage and drove 5-6 miles and stopped at stop sign. In the direction I was going the road was slopping slightly downhill at stop sign so I applied slight pressure to accelerator when proceeding through stop sign intersection. My auto demonstrated the same sequence as previously described acceleration issues. I did not have driver side floor mat. Tech found no problems. Dealer opened the case [xxx] & advised fts. I called Lexus customer service and was told someone would call me.
