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. *tr
