The 2011 Buick Lacrosse with a 3.6 had popping sound upon starting when car was 5 days old; brought to dealership and was asked if I was sure it was my car. They checked vehicle and could find nothing wrong. The problem is intermittent. It popped upon starting 8-9 more times in 3 weeks. Upon leaving a restaurant, the vehicle would not start & had no power; onstar was of no use. Dealer had car towed to them; kept car for 10 days and put 160 miles on it and I was told that they reprogrammed 3 computers but could not replicate the popping sound. I picked up my car and discovered that it had been hit while at dealership. Dealership had car painted. I got my car on Tuesday, Thursday it popped twice. Returned car to dealer again. They told me to pick car up that they could not find a problem. They found that the exhaust expanded upon starting and made a poofing sound. They said that there was nothing more they could do. I have been in touch with Buick executive offices. The car has 1087 miles on it. It had 287 when I purchased it and they put 160 miles on it when they had it. I've only had the car 6 weeks and 2 of those weeks it has been in the shop. They refuse to give me another vehicle like the one I have or give my money back. What options are left?? lemon law. I don't really want to do that. I love the ride of the car and the features, but I cannot enjoy it at all and do not feel safe driving it.
