While driving on the highway at 60 mph, warning on dash came on saying “engine power reduced” and drop down speed to around 25 mph and I could not accelerate more than 25 mph on the highway which could have caused an accident because of the traffic flow behind me. I put a code scanner under the dash and it read code P2138, Throttle pedal position sensor switch.

Driver side headlamp draws moisture, keeps blowing bulbs at 104.99 a pop. Water gets in the headlight assembly and shorts out the ballast. This happens even when driving down the road at random. It could be pitch black and suddenly you have no headlights and are forced to drive with only fog lamps

Preparing to park into a parking space in an off street parking lot the vehicle forcefully and rapidly accelerated on its' own and crashed into a fence. I was not accelerating. I attempted to stop the car using the brakes but they did not engage quickly enough to stop the rapid, forceful, and without warning acceleration. Buick has been contacted about the defect. Buick ran extensive diagnostics on the car and denies there is a defect. Police came to the scene and advised that given the 2 other incidents that I have experienced, the car is unsafe to drive given potential damage to others. A police report was filed.

The diagnostic tip has the technician inspect the high pressure fuel pump body markings to confirm it is an original manufacture part. If it is not an original manufacture part, they should install one and evaluate the vehicle.

This Preliminary Information communication provides information to the technician about vehicles that have had multiple repair attempts that are being performed on customer’s vehicles that exhibit vibration conditions without utilizing the support of General Motors Technical Assistance Center. If valid vibration frequency or Road Force Variation data has been collected and a repair attempt does not correct the customer complaint, contact General Motors Technical Assistance Center for further support. For any vehicles that remains unrepaired after being at the dealer for three days or more and a related bulletin or PI is not found, contact General Motors Technical Assistance Center for further support.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
