general problems of the 2006 Lexus GS300

While bringing the car to a stop, I am experiencing a very hard downshift from 2nd gear to 1st gear. This hard downshift is so abrupt that it feels as if you were rear ended. Research shows this being an electronic failure in the electronic control module backed with hundreds of complaints of this exact issue to this particular year, make and model. In several cases, mentions of a class action lawsuit against Toyota/Lexus have been mentioned. It's a costly, yet unnecessary repair caused by a flawed design within the electronic componentry. . Considering the reoccurrence of this issue on a mass scale, it may be one best addressed via recall.

The contact was driving 40 mph and applying the brakes as she approached an intersection, the vehicle did into respond and the contact crashed into the rear of another vehicle. The contact stated that the frontal driver and passenger air bags did not deploy. A police report was available. The vehicle was taken to the dealer who performed a diagnosis on the brake system and air bags but did not locate a failure with either. The driver sustained injuries to the back and neck. The rear passenger sustained injuries to the nose and back and the front passenger sustained injuries the breast due to the grip from the seat belts.

I drive a 2006 Lexus Gs300. Last fall,as I backed out of my parking space - in a building - my car "took off" and hit a cement wall. ( at first, I thought I hit the gas pedal in error however, after what happened next, I knew that was not the case. Fortunately, there were no pedestrians in the parking lot. ) I put the car in drive and it "took off" again. Luckily, I hit a cement parking bumper that stopped me. All this took place in maybe 15 seconds or so. Not realizing there was anything terribly wrong with my car, I steered around the bumper. The car continued to accelerate and I was headed for another cement wall. I was applying my brakes with all my effort and finally I came to a stop a few feet from the wall. Shaking, I drove my car directly to the Lexus dealer and told him what happened. (at that time I used the term "take off" as I hadn't heard about all the acceleration problems) he ran my car through a computer check and assured me that he could find nothing wrong. Several weeks later a friend asked me what kind of car I drove and told me about all the problems Toyota was having. I drove my car back to the dealer and asked him to recheck the car. He did, and again assured me that there were no problems. We bought this car used less than 1 year ago with just 12,000 miles on it. It occurred to me that it was possibly traded in because it had accelerated when the last owner had it. The dealer checked and said there had been no previous acceleration problems. One last bit of info. . . . I'm not really sure the exact month I experienced the problems. And finally, even though I have not had any acceleration problems since last fall, I am still nervous every time I drive my car. Please advise. Thank you.
