2011 Buick LaCrosse with only 59k miles stalls on me in the middle of rush hour. Luckily I was driving on the slow lane at 65 mph or a pile up accident would of occurred if driving in the fast lane or middle lane. While driving the AC was on and I started to smell burned like plastic odor. Then all of a sudden the door locks went crazy locking and unlocking and the car stalled. It started back up on its own. Got off the highway to check under the hood and couldn't see anything wrong. I started to get back on the highway. I was driving home and had 56 miles to go and again at 10pm on the highway, 32 miles to get home the car stalled on me again. This time everything turned off, everything locked up and had a chance to steer it to the edge of the road. I had to call a tow truck because car wouldn't start. They took the car to a Buick retailer and they said they couldn't find nothing wrong because no codes were shown. I will not drive car again. This is a serious issue and seen many complaints about this and nothing has been done or recalled. That day me and my family and others in the highway could have caused serious injuries or deaths.
