Front suspension noise due to broken sway bar links rusted front right and front left. Front brake lines and fuel line badly rusted but not leaking yet. If front fuel line leaks it will leak onto engine rear to cause fire. If front brake line leaks I will not be able to stop car. I had reported to NHTSA when my rear brake lines leaked preventing me from stopping in 2011 but luckily I was going very slow. My driver side window failed preventing me from opening window, needing replacement in May 2014.

Engine shuts off while driving, so far, only at lower speeds. Sometimes, by putting in neutral and turning key, engine starts again. Other times, it has to set for a while. Put new battery in 11/7/2013. Problem persisted. Three auto repair shops, including a Buick dealership, have checked it out, but it does not die on them in the amount of time its in their possession so I was told there was nothing they could do. Typically, it happens after it is driven at least 20 miles. Came very close to being rear-ended as I was unable to pull off the road enough to be out of the way on a road with hills and blind spots.

Vehicle had been decreasing in miles per gallon steadily, reason for taking it to the shop. Was told that the upper intake cover was cracked at some point in time. This could have ceased the engine due to antifreeze seeping into the crack.

Shortly after taking delivery of vehicle which had 60 miles on it, I noticed when accelerating from a stop or accelerating when turning the car lost power.I would press the gas and it wouldn't go.took to paul batt Buick & skill Buick many, many times, never found problem.at 30K miles, Buick said I should change fluid & check the pan fluid, which showed nothing.problem still occurs.this could be a hazard if vehicle behind me thinks I'm moving and car slows to a near stop w/O brake lights going on. I have 55K miles on it now & problem still occurs.neither Buick or the dealer has attempted to resolve this problem.skill Buick and paul batt Buick were less than helpful.
