2006 Buick Lucerne Fuel system Problems

“Vehicle is a 2006 Buick Lucerne cx with 40,000 miles. About 2 months ago it started to go dead without any warning. The first occurrence was jan 15, 2014 with my wife driving. The next shutdown on mar 4, 2014, occurred in rush hour traffic. There was an audible signal accompanied by a service traction control warning, followed immediately by a throttle control warning and complete engine shutdown. I was able to coast across 2 traffic lanes into a parking area with great difficulty while steering and braking without power assist. Tried to restart the engine but got ?throttle disabled?

“This has happened at least 4 times. We asked the Buick dealer if there have been any complaints and they said no. It has happened the last 4 years and again today and it is kind of scary as it could be dangerous if we didn't put our foot on the brake firmly when it happens. What happens is if we are pulling into a parking place or our garage slowing to a stop the accelerator goes down on its own and if we did not put our foot on the brake it would take off on its own. It last only a few seconds maybe 5 or so and then it stops. We have checked the floor mat and this is not the problem.”

“I own a 2006 Buick Lucerne. The vehicle slows as if it is going to stall and cut off, it picks up speed on its own ,and when stopping the vehicle cuts off. It presents a safety hazard in that most of my traveling is done via the expressway. When the car slows down I am at the mercy of the driver behind me. If he is going too fast and tail gates then I am sure to be rear-ended. I have taken this car to the dealership five times,and they could not duplicate the problem. Diagnostics showed nothing. Service department manager drove vehicle while in shop for fifth time and experienced the problem. …”
