This vehicle stalls/cuts off while driving. It can occur while driving or taking off from a stand still. It maintains a stored history code p0014 and after service will reappear. Especially dangerous while driving in the national capital area. Buick has a notice about the engine control module and that has to be reprogramed for that vehicle model and my VIN number falls within that bulletin. The problem is that it doesn't work and the vehicle shuts off at a moments notice. Right now I'm afraid that my life or someone else is ir real danger. Unfortunately I'm not the only one. While searching for a solution I found numerous owners with the same problem/ same complaint. I hope it doesn't take the loss of life to address this issue.

2011 buick lacrosse (60,000 miles - properly maintained by 73 year old man) broke down on interstate hwy. While vacationing in knoxville, tn - buick begins to stall and the engine light came on (was flickering and no acceleration). We stopped immediately at a gas station and called aaa - who towed us to a certified aaa repair/tow company. We initially suspected it would be the fuel pump or filter . Mechanic in knoxville who is a ase certified mechanic for 40 years said it wasn't the fuel pump so he put his diagnostic tester and determined there were more problems and started to take apart the engine....and found the main valves were broken and fell into the pistons. Engine failure and he said in his 40 years this had happened only 3 times but not on a 2011 car with only 60,000 miles. He said if we would have continued driving, the whole engine would have blown up. Called the local buick dealership and found out no recall, nor did we have the extended warranty (a big mistake - and we loved the lacrosse thinking it would last a long time). Looked up blue book value - worth $11,000 (with running engine) and a new engine would be approx. $8,000 and would take a week to replace. Sold the car to the mechanic in knoxville, tn) and purchased a new toyota avalon in knoxville. Very very disappointed in g.m.
