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.

The contact owns a 2005 Acura TL. The contact was driving approximately between 40-45 mph on normal road conditions and suddenly, there was a slow power response and the transmission failed without warning. The driver was able to pull over to the side of the road. The vehicle was towed to an authorized dealer. The failure was contributed to the transmission which required replacement.

On 9/15/09, while pulling into a parking lot in a parking garage at work, my 2005 Acura TL accelerated (on its own) and crashed into the concrete barrier causing the air bag to deploy. I did not have my foot on the gas pedal and the car mat was not stuck under the gas pedal. I was coasting into the parking space when the car "took off" and accelerated into the barrier in front of the garage wall. For about the last two years or so, the transmission on my car would regularly cause the car to accelerate for a short time right after the gas pedal is pushed. It "jerks' forward when going at low speeds. It happens regularly/daily. I brought this to the attention of my Acura dealer on two occasions when I brought my car in for service. They told me there was nothing wrong. After the accident above, I told them to check out the problem and they told me nothing is wrong. I am still waiting for my car to be repaired from the accident and I am concerned that it is unsafe to drive. The impact of the incident resulted in bruises and neck and shoulder injuries.

We've serviced our vehicle regularly and as recently as 2 times in the last year at the dealership (once for service and the other for a recall) and 1 time at an independent transmission shop. The service people at Honda found the fluid to be good and said "the transmission does not need service... have it checked at approximately 62,000miles, which we did. We had the transmission completely flushed and the fluid replaced at approximately 62,000 miles. The car is a 2005 Acura TL. It was out of warranty with approximately 75,000 miles on the vehicle. We were driving on the freeway when a nearby motorist directed us to pull over. Apparently there was smoke fuming from the vehicle. At that point there were severe power fluctuations and the car rev'd over 5000 rpms. The transmission had discharged a tremendous amount of fluid and nearly caught on fire. We had the vehicle assessed independently and then at the Acura dealership in montclair. Both found the transmission to be completely burnt and inoperable. There is a serious problem with the design of the Acura TL transmission that can lead to accidents and/or car fires.

I was driving on the highway (684south), and my car's automatic transmission failed on my 2005 Acura TL. As I stepped on the accelerator, the car had no motion. I pulled over immediately, and I called aaa to tow my car. The company that towed my car had inspected my car the following day and informed me that I was in need of a new transmission. I had then called aamco in mahopac, NY, that specializes in transmissions, to get a second opinion. After making a transcan, they informed me that the torque converter failed, where it caused a great amount of heat affecting the turbine assembly causing the gears and converter clutch to break down. I was informed that this was a common problem in many cars made by Honda and Acura. Therefore, I am respectfully asking your organization to investigate if there are other complaints similar to mine. I am the second owner of the car, which I purchased at 25,000 miles, and when this problem occurred, it happened at 75,000, where I was driving for approximately for about one hour on the highway.
