The contact was able to veer to the side of the road. The vehicle restarted independently after 10-15 minutes.

The vehicle was taken to the dealer on two occasions, and the dealer retrieved diagnostic test codes: p2138 and p2122. The dealer replaced the throttle body and the accelerator pedal; however, the failure persisted. The contact stated that the failure mainly recurred while making left turns. The manufacturer was notified of the failure and informed the contact that they could only assist after the vehicle had been taken to the dealer.

Tl the contact owns a 2010 Buick Lucerne. The contact stated that the vehicle did not pass inspection due to engine mount failure.

The dealer was not contacted. The failure mileage was 61,000.

Engine mount had to be replaced twice since I have owned this vehicle, the first is listed above, the second time is sept, 24, 2012 and the mileage on the vehicle is 31,000. This is unusual and make me wonder if the part is deflective. A vehicle less than three year old has two engine mounts replace. This to me is a safety issue, what if more than one breaks or all of the engine mounts break then the engine will fall out of the vehicle which is unsafe. Please investigate to see that this is not a common issue with the 2010 Buick Lucerne.
