I have had multiple issues with my 2012 Buick Lacrosse, it started sooner than this with my air deflector falling off at 75 mph and almost flipping my car. This time on July 30th my vehicle went completely out from the memory loss, the transmission just stopped working and I was stalled in one of the busiest intersections in my city. As I was trying to get my vehicle to move again the light turned red and an 18 wheeler almost broadsided me. I found out that back in may a safety recall was sent down on my vehicle. The ones with easiest the battery in the back can catch fire and cause problems. I did not even get my notice until I had picked my vehicle up and GM said they weren't going to send notices until they "had a problem" well parts on national back order due to the problem seems like a huge problem. GM keeps giving me excuse after excuse and does not want to help me in all the problems I have had. My air deflector falling off they said could not happen, I said it did and it is gone, can't reproduce something with nothing there. In front of my neighborhood a Cadillac escalade dropped his air deflector too, same side dropped, same side twisted off, nothing in the road to cause the problem and I have the proof yet GM doesn't care and still says it doesn't happen. My mechanic said if it is not installed properly they will just fall off, the air deflectors on GM products are held on by only 2 bolts, the other spots have never been bolted on, now I have a damaged vehicle and GM says it doesn't happen. I have almost been killed three times and my daughter once in this vehicle, how normal is that? please help!!

Un smooth shifting around 30 mph, causing the car to jerk or brake feels like the assist is not sensing, causing the had to dealership nothing they can do all check out but the problem is still there.

I parked the vehicle in parking bay at a gas station and went inside. I was in there approximately 3 minutes and a gentleman game into the building and asked did anyone in there own a Buick Lacrosse. I said it was mine, he told me it had rolled out of the parking bay towards his Mercedes, he had stopped my vehicle. I subsequently found I had turned the engine off while the vehicle was in drive so there was no braking effect. Where I had parked the pavement was a very gentle slope so I did not notice any movement of the vehicle when I alighted from it. This model has remote wireless key so you do not insert any key to either start or stop the engine. To start you have to have the key within the vehicle be in either park or neutral and depress the foot brake and then press the start button. What I have found is when turning off the engine the vehicle can be in any of the following, drive, reverse, neutral or park. So if you happen to be in anything but park and then turn off the motor then the vehicle is free to roll away with the possibility of it hitting something or worse still hitting a person. With all automatic vehicles I have previously owned you needed to put the vehicle in park before you could remove your key and after exiting the vehicle you knew it was effectively braked and was not going to roll away. I believe this matter needs addressing before it does result in a possible fatality. To alleviate the possibility of the vehicle moving either the engine/transmission management system needs to be altered so that you must put the vehicle in park before turning off the engine or at the very least there should be either an audible alarm or visual alarm to alert the driver that the driver has not left the vehicle in a safe condition. After contacting the dealer it was determined this anomaly applied to all of these vehicles.
