My vehicle a 2011 Buick Lacrosse cxl 2.4L engine RPO laf. I have a problem with the engine making noise due to balance shaft chain special coverage recall 12313 where back then they included in the recall the balance shaft chain, tensioner, and also the engine mount high pressure fuel pump, then to say this bulletin has been revised to remove special coverage adjustment for the fuel pump that is now included in voluntary emissions recall 43180. Updates have been made to the part information, service procedure, and warranty transaction information sections. Please discard all copies of bulletin 12313B. Came the revised 12313B and now as of September 2016 revised again to 12313C. When you look at the 43180 it does not include the 2011 Buick Lacrosse with the same engine RPO laf. I've called GM various times and spoke even to the GM dealer, my car was even at the dealer sitting there for weeks to only say it's not covered that I have to wait for it to get recalled. My vehicle has the same exact symptoms, the oil smells like gas, and I can't shut off the vehicle, it stays running and the only way to shut it off is putting it on drive then shutting it off. All this due to on some 2010-2011 model year Buick Lacrosse, Chevrolet equinox, and GMC terrain; and 2011 model year Buick regal vehicles, equipped with a 2.4L engine (laf), the chrome layer on the balance chain pins may wear, allowing the chain to stretch. This would cause an engine noise, and if left untreated, could cause the chain to break, leading to engine damage. This is causing the engine to not run right and a hard time to accelerate GM case # 8-2573359821

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.

When turning left at a traffic light, my car lost power and I wasn't sure I was going to make it around the corner. After a few seconds my car regained power. 45 minutes later, I made a right turn into heavy traffic and then felt a sudden lurch. I looked in the rear view mirror and saw that my trunk had popped open. I managed to get off the highway, parked the car and turned off the ignition. I got out, closed the trunk, got back in the car, and fastened my seatbelt. Before I could close the door, the trunk popped open again. This occurred three times before the trunk finally stayed closed. A few minutes later, I parked the car, opened the door, started to get out and the warning chime sounded. I got back in and saw that the on the console shift lever that indicates your car is in park was lit up even though the car was turned off. In order to get the light to go off, I had to restart my car and then turn it off again. Next I pushed the onstar phone button and asked to call my home. I got a busy signal. I called a second time and my husband at the number I was calling, heard me telling onstar call my homeŁ but I couldn't hear him trying to talk to me. All of these things happened within 1 1/2 hours. The next day, I found that I could not lock the door by touching the lock spot on the outside door handle. Then I could not unlock the car door by pulling on the door handle when the key was in my pocket. I have had the car for 1 year and eight months and the driver's memory seat has often lost its memory. Sometimes just one button but most of the time both buttons. Prior to this I had been having trouble with my trunk. I'd leave my car parked in a public parking lot and come out to find my trunk wide open. On May 3rd the GM dealer replaced a part hoping to fix this problem.
