Tl* the contact owns a 2009 buick lacrosse. When the contact started the vehicle, the check engine and service trac system warning indicators illuminated. Also, the vehicle would not exceed 15 to 20 MPH when the accelerator pedal was depressed. The contact took the vehicle to an independent mechanic where the accelerator pedal was replaced, but the failure recurred. The dealer was not contacted. The manufacturer was made aware of the failure and started an investigation. The manufacturer informed the contact to call the federal safety agency to file a complaint. The failure mileage was 99,000.

This has happened twice. Twice I was going about 55 or 60 miles per hour and suddenly I had reduced power. This happened in july and then several months ago. My engine light has come on and codes show that p1125, accelerator pedal position sensor fault, and p2138 accelerator pedal position performance. I recall I got a letter from gm about this matter, but I can not locate at this time..

Car was towed to auto repair shop where the airbag light and check engine lights were illuminated. Have had four diagnostics performed and problem not found. Advised a complete tear down of passenger seat would need to be done to locate issue which is costing me an exuberant amount of money for something that should be fixed on a recall.

This has happened numerous times. The first time the check engine light came on, I don't recall the message I actually got; but I took it to a dealership and they replaced an emission control item which seemed to do the trick for awhile. Eventually, as I was driving along some time later, the message "reduced engine power" came up; and I could feel the engine immediately start to drag. In about 30 seconds to a minute, "traction control off" or something similar comes up. I stopped to look at the manual which said to shut the engine off, wait a few minutes, then start the car and this would clear the code so that the car would run normally. I did this, and I saw that the car was operating more normally but the "check engine light" stayed on. After several stops and starts, the light went off. This has happened more times than I can count. On 6/3, I took it to a dealership because it seemed to be happening more frequently. The only thing they could find that might be causing it did not seem to be the problem, but they worked on the x101 connector and test drove it 16 miles w/o a problem. Two days later while driving to work (after driving about 20 min.), the same thing happened again. Another garage where I had my oil changed ran the codes and found that p1125 - fuel & air metering and p2138 throttle/pedal position were listed. I gave this info to the buick dealer to see if the problem could be fixed. The car is no longer under warranty except for emission controls, so I paid for the work. They were not sure that the problem was repaired. It turned out that it wasn't. Now, what? Do I just keep taking it back and paying for things to be tried?
