Trunk randomly opens. It has happened many times and my key fob is not in my pocket. I keep it on a clip on my purse when not in use. Once I noticed the alert in my car popped up on my display while driving @ 55 MPH and I did stop and closed the trunk. Most of the time car has been stationary. Once it must have been opened during the night and it rained. Whole trunk was very wet. Several time while at work and my car was parked in the parking lot--had someone tell my my trunk was open.

First issue car will shut off driving down the freeway doing 60 70 miles an hour it will just shut off and I have to coast to the side and wait and wait till it starts again very dangerous. Next issue is the airbag light flashes on and off I'm assuming do I do to a pressure sensor in the passenger seat which I have a daughter that sits in the passenger seat and I don't know if the airbag is working or not. Next problem are the door locks they lock they don't lock the left rear does not work I have to manually pull it up and push it down if I want it locked the key fob warning is always on my dash saying key fob battery is low I replaced it I replace the key fob itself it just works when it wants to. Next problem the check engine light comes on goes off comes on goes off and therefore I cannot use my remote start if the check engine light is on it has been checked there's nothing wrong with the car nothing shows up if you check the gauges I don't know what to do I paid a lot of money for my remote start cannot use it and I'm in minnesota. I need my car fixed it's reliable it's a good car it's what I drive it's my car I have a daughter's life at stake in my car I expect it to be trusted in the car that I bought after reading all the complaints on the site regarding the same issues that my car is having I am hoping literally hoping that your company is willing to fix these issues in my car and all the other people that are waiting in line cuz this is ridiculous

All 4 windows in the vehicle go down when the driver and key fob are no where near the car. Only 1 time has this happened while the driver and key fob have been in the car and the driver was not touching the fob. In this case the driver put up the windows, opened the door, during which the windows went back down. All other instances the windows went down in various locations with no commonality (my parent's house while we went shopping, the gym, walmart.) this has occurred I believe 6 times over 3 months. The vehicle was purchased april 2017 and has under 11,000 miles. Twice this has occurred and during or immediately following a rainstorm. Once causing extremely soaked seats and I don't know how the inside electronics, such as radio and GPS were not ruined. The first time my car was loaded with over $500 in toys and thankfully none stolen.

Key fob with "switch blade" type of key breaks off leaving key stuck in the ignition. I turned the key to start the vehicle and the key snapped. I read on forums this happens with a lot of people.

What is wrong
This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Risk
If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy
GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1‑800‑521‑7300 (Buick), 1‑800‑458‑8006 (Cadillac), and 1‑800‑222‑1020 (Chevrolet). GM's number for this recall is 14299.

Electrical systemReported June 12, 2014 · 14,765 vehicles affected
What is wrong
General Motors LLC (GM) is recalling certain model year 2014 Buick LaCrosse vehicles manufactured April 30, 2013, to September 1, 2013. In the affected vehicles, a wiring splice in the driver's door may corrode and break, resulting in the absence of an audible chime to notify the driver if the door is opened while the key is in the ignition. Additionally, the Retained Accessory Power (RAP) module may stay active for ten minutes allowing the operation of the passenger windows, rear windows, and sunroof. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 114, "Theft Protection and Rollaway Prevention," and 118, "Power-Operated Window, Partition, and Roof Panel Systems."
Risk
Without an audible indicator, the driver may not be aware that the driver's door is open while the key is in the ignition, increasing the risk of a vehicle rollaway. If the passenger windows, rear windows, and sunroof can function when the vehicle is turned off and the driver is not in the vehicle, there is an increased risk of injury if an unsupervised occupant operates the power closures.
Remedy
GM will notify owners and dealers will inspect the driver door window motor harness, and replace the electrical splice, as necessary, free of charge. The recall began August 2014. Owners may contact Buick customer service at 1‑800‑521‑7300. General Motors number for this recall is 14235.

Remedy
GM will notify owners and dealers will test the GCM and replace it, as necessary, free of charge. The recall began on June 11, 2013. Owners may contact GM at 1‑800‑521‑7300. GM's recall campaign number is 13136.

A software problem may cause the transmission to inadvertently shift to Sport mode removing any transmission-related engine braking effect.
Risk
