Tl* the contact owns a 2008 buick lacrosse. While driving approximately 50 MPH, the accelerator pedal depressed independently and the vehicle accelerated without warning. The brake pedal had to be depressed with extreme force in order for the vehicle to stop. The vehicle was taken to a dealer where it was diagnosed that the throttle body failed and needed to be replaced and the ecu needed to be reprogrammed. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.

While driving, the engine light came on, followed shortly thereafter by the traction control light.then the engine began to lose power and the accelerator pedal did not work. A notice appeared on the dash control: "engine power reduced" and "service traction control". If I held the accelerator pedal down all the way to the floor, after about 5 seconds the car began to accelerate quickly. I could then maintain speed by alternately stepping on and releasing the accelerator pedal quickly. Accelerating from a stoplight is a very slow and disruptive (to traffic) process. This has happened multiple times and has failed several attempts at repair. On some occasions, the car has begun to accelerate on its own during this period of malfunction, such that I have had to ride the brake pedal. On some occasions this problem has remedied itself after a couple of days, with turning the engine on and off to reboot. The problem can last for days at a time. I have replaced the throttle body sensor to no avail. Interestingly, I also owned (until last week) a 2007 lacrosse which does the exact same thing, and has also had the throttle body sensor replaced with no luck. I have seen multiple descriptions of this by people online, describing exactly the same conditions and warnings. This is a significant safety issue when it happens, as I cannot safely accelerate in busy traffic, and the car slows down to speeds unsafe for the conditions. I find it difficult to believe gm does not know about this, in that I have had the same problem with 2 lacrosses. Thank you.

Tl* the contact owns a 2008 buick lacrosse. While driving approximately 40 MPH, the engine stalled. The vehicle was towed to the dealer where it was diagnosed that the coil and mother board needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was taken back to the dealer where it was repaired, but the repairs were unknown. The manufacturer was notified of the failure. The approximate failure mileage was 136,000. The VIN was not available. Updated 11/09/15*lj the consumer stated at the time of the first coil replacement, he asked the dealer if it was a common problem and the dealer stated it was not. After the first incident in 2012, in which the coil and mother board were replaced, the exact failure occurred in 2015. The consumer was informed the coil and mother board need to be replaced at a cost of $700. During both incidents, the vehicle shut down while in the midst of driving. Updated 01/05/16.

After having a gm dealer (roberts-robinson buick gmc - excelsior springs, mo.) repair the factory recall key issue. The car still stalls at hiway speeds. Was told it was the "powertrain control module", finally, after 3 visits to the dealer. I've read hundreds and hundreds of complaints on-line with owners of buick products similar or the same having the same issue. This would seem to be a very serious health hazzard. Although my dealer has done all they could and have been very accomodating, it would be beneficial to all that is having or has had this problem to get help from gm since this seems to be a very wide-spread & common problem.

I was traveling at 35 MPH when the vehicle just stopped running. I had all I could do to get the vehicle stopped and off the road because neither the brakes or power steering would work.

The engine died without warning and would not restart. Fortunately, I was on a quiet street and so I could stop curbside. Lights etc. Worked but power steering, power brakes, engine were all dead. The cause was a cracked ignition coil that shorted and "fried" the ignition module. This was an original-equipment part, probably a delphi gn10123 (from my internet research; I could be wrong). Had this happened on a high-speed road, the results could have been disastrous.
