While driving on I95 in Georgia on the way to Florida 12-28-08 my 2003 Buick Lesabre transmission started bucking and jolting car as it shifted. Took to garage and it was determined that the torque converter locked up, this car had the transmission oil replaced at recommended 50,000 miles, besides the 2200 dollars to replace transmission we had to get hotel room, meals and a rental car to continue trip as the replacement transmission could not be delivered right away.

This incident is regarding a sudden transmission failure on a 2003 Buick Lesabre, purchased in may of 2003. In January of 2008, with 47,692 miles on the car, the transmission suddenly failed while the vehicle was in use. There was no warning before the incident - the vehicle lurched, bucked, rapidly picked up speed and rapidly lost speed without warning. This situation was incredibly dangerous to both myself, passengers and other motorists. My remedy was to immediately pull over and turn off the engine. The service manager at the vehicle repair center explained that this is a common problem with post-1997 Buick, in which there is a typically faulty transmission. He cited that he may see close to 100 similar cases per year. In fact, while I was discussing my car with him another post-1997 Buick came in with the same problem. It seems that a chronic manufacturer's defect exists that affects the safety of the vehicle, and it has not been addressed by the manufacturer with a product recall or warranty concession for people who have experienced transmission failure.

The vehicle eventually accelerated; sometimes taking 15-30 seconds and up to five minutes. The vehicle has been to the dealership five times.
