Whenever we fuel our 2011 Buick Lacrosse cxs it would not fully start and after several attempts, it would run the battery down. After the second incident, it was observed that if we rapidly pump the accelerator while the vehicle was trying to start it would pick up and fully start. This is what we have been doing and is still doing, regardless of the fuel station (exxon-mobile, shell, murphy/walmart, citgo, chevon, valero, fuel depot, ect.). here is a list of things we have attempted: 1) with the gas tank at about half, open the gas tank put the gas pump into the tank, don't pump any gas, close the tank, start the vehicle (maybe opening the tank was the culprit): All is fine. 2) with the tank at about half, full the tank (different station), start the vehicle: All is bad. 3) with the tank at about empty, full the tank (different station), start the vehicle: All is bad. 4) with the tank at about quarter, full to half tank (different station), start the vehicle: All is bad. My conclusion is that the vehicle is creating the problem and needs to be corrected. Before reaching this point, I had to call for road service twice. In the first case the vehicle was towed to a dealership and they found nothing and the second we jumped the vehicle.

Twice after filling up with gas, my car was oils not start at the pump. Each time I had to wait several minutes before it would actually start. The second time it happened, I waited, it started then immediately quit again. There is a very hard start when it attempts to start as well. The engine light came on then immediately went off. I took the car directly to the dealership where it had to remain running until they could get it in. This was 540P on Friday, May 25th before a holiday.

The contact owns a 2011 Buick Lacrosse. The contact stated that the vehicle began to leak fuel from under the housing unit. Whenever the contact attempted to accelerate from a stop, it would jerk and hesitate before accelerating. The contact took the vehicle to the dealer where it was diagnosed, but not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 33,000.

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
