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.

2005 Buick Lacrosse was bought used with slightly over 44,000 miles back in may of 2008 and was taken to the dealership for acceleration and transmission shifting issues several times since purchase. Car would not accelerate, losing power while going up hills, bogging down while slightly accelerating to pass, and the transmission would shimmy between 1st and 2nd gears, and clunk when coming to a stop. Naturally, the dealership played the guessing game replacing the catalytic converter, the torque converter and sensor, and even re-programmed the computer, and could no longer duplicate any problems once they had run out of their options two months ago the car developed a clicking noise while turning the steering wheel either direction, the dealer was able to determine within an hour that it was the intermediate steering shaft and proposed lubrication to resolve the issue for a cost of over $300. Sounds like they were already aware of this popular issue.

2005 Buick Lacrosse transmission failed at 81,000 miles- took car to dealership before extended warranty expired with the hard shifting problem before the transmission went out they stated it wasn't the transmission- transmission had to be rebuilt at my cost $2,500. Per google search this has been a common problem other owners of the same car have had.

At times, car will not accelerate. When attempting to increase speed, usually when accelerating into high speed, the car does nothing for a few seconds, then it begins to buck, still with no speed acceleration. It has lasted from a few seconds to 10 minutes. It only happens periodically, and no trouble lights appear on the dashboard.

Car looses power while trying to accelerate. Have almost been rear ended on a couple of occasions. Once while on I-95 in Georgia, a semi-truck almost rear ended the vehicle. The dealership says it cannot duplicate the problem even though they say it could be the wireless accelerator they will not replace it unless they can personally duplicate the problem.

The vehicle had a hesitation upon acceleration between 40 and 60 mph. Also noise was coming from the engine. Especially on a cold start. Brakes were pulsating.

: the consumer stated while driving the vehicle surged. It was taken to an independent repair shop. The mechanic determined it was the transmission. The vehicle was taken to the dealership, were a diagnostic test was performed and no codes were found. While turning right there was a clicking noise in the front end.
