  • 156,000 miles
The contact owns a 2000 Buick Lesabre. While the contact was driving approximately 55 mph, the vehicle unexpectedly increased acceleration up to 70 mph. The brake pedal was applied numerous times with extensive force and the vehicle continued to accelerate. The contact down shifted to a lower gear, followed by no response. The speed rate reduced between 10-15 mph when the gears were shifted into the reverse position which allowed the vehicle to stop properly while the brakes were applied. The vehicle was towed to an independent mechanic for storage due to the safety issue pertaining to the acceleration malfunction. The vehicle was not diagnosed or repaired. The failure mileage was approximately 156,000.

LeSabre 6-cyl

  • 66,000 miles
I placed the shift lever in reverse and depressed the accelerator pedal. The car accelerated rapidly. I depressed the brake pedal very hard and held it down. The car alternately stopped, accelerated, stopped, accelerated etc 3 or 4 times before coming to a full stop: Total distance traveled - approximately 30 feet. I repeated the above procedure in forward gear and got the same result. Prior to this incident the throttle system did not appear sticky or off-normal. Post incident, the throttle appeared slightly sticky. Approximately 18 months ago I reported a sticky throttle to my Buick dealer, they serviced the throttle system and the problem was solved. As stated above, the throttle did not give indication of a problem this time.

2000 Buick Lesabre experienced sudden acceleration on three occasions. The problem was intermittent. On one occasion, the consumer was slowing to stop behind another vehicle that had stopped at a stop light when the consumer experienced sudden acceleration and caused minor damage. The last time this happened, the vehicle had come to a complete stop at a signal when the sudden acceleration occurred. The dealer was unable to find the cause of the problem.
