Rear door lock unlock mechanism malfunction. Locks but won't unlock and will not open from the inside. In the event of an emergency someone can get stuck inside the car because the door wont open. And no, the child safety lock is not engaged.

Was driving on freeway with cruise control on then suddenly the cruise control disengaged. When I looked in the rear view mirror I noticed that my 3rd brake light was coming on by itself and staying on and I was not pressing brake. Brakes come on and stay on when not pressing brake pedal and turn off when brake pedal is pressed. Makes other cars behind me think I'm braking when I'm not and when I do brake it looks as if I'm not braking. Risk getting rear ended because of this. Safety issue.

First front passenger side door lock stopped working. The left rear passenger lock stopped working and now right passenger door lock does work. All locks do not respond to fob or switch activation. Locks do not respond to placing the car in drive and do not lock automatically.

The first incident occurred while under warranty Nov 9th 2009 when the door lock became unresponsive. They replaced free of charge. Today the remaining 3 do not work. When I start the car and drive off, it is my belief based on normal operation of these locks, that my doors are locked and passengers are safe. The reality is just the opposite. Not only does it become a safety issue as described, but it also becomes an issue when you park your car, lock your doors with the remote, and walk away with confidence that your car is locked when in fact it is not due to the faulty cheap product used in this car, and others manufactured by GM. When I went online to research, I was surprised by the number of people on various blog sites complaining of the same issue. I contacted GM and the best they offered was to replace all 4 locks for half price. That is $500 instead of $1000. While I appreciate their offer, I know for a fact a replacement actuator costs between $5 and $10, and it's not entirely about the money. It's a matter of right and wrong, safe and not safe. This issue in my mind is more about the safety of people thinking they are safely locked in their car by a system that is designed to do exactly that. This is not optional equipment either. These locks are standard equipment that I expect to work and keep me and my family safe much in the same way I expect my brakes to stop the car. I would like to see this became a recall on this and other vehicles like it. Thank you for your time.

1st incident (2/4)- vehicle was placed in park. Driver's side door would not open. Door unlocked as it should but door remained shut. Had to exit vehicle out of passenger door. Tried opening door from outside, remained shut. Left vehicle for 20 minutes, returned and tried opening again would not open with remote. A few hours later, door opened like nothing happened. 2nd incident (2/17)- same as before. Turned on and off car again still could not open door. Exited out of passenger door. Came back to car after 2 hours and door would not open. Arrived home 20 mins later, it opened. Tried closing door and it would not close. After 4 tries, it finally shut and was able to lock car. Since then I hear air coming in the car while driving but have checked the windows and they were all up. Also noticed static in radio while driving. It would stop and start again really quickly. A lot of static when playing MP3. 3rd incident (2/19)- same occurrence as before. Driver side door would not open; started working again after a few hours. Door would not lock until after a few tries. Continued static in radio even after door issue. 4th & 5th incident (3/4 & 3/5) - same occurrence. Driver side door would not work all day. 6th incident (3/5) - door would not open this morning. 30 mins later it opened. 5 hours later after taking it to Firestone to check out problem, door would not open. (locked technician inside the car). Technician referred me to GM dealership for further diagnostics. He suggested it might be an electrical issue. This is really frustrating. Dropping vehicle off tonight to be seen on 3/6.

Cruise control became disengaged while driving on the highway and would not re-engage for the remainder of the trip. Also, the brake lights have reversed functionality; brake lights will not illuminate when pressure is applied to the brake but will remain illuminated when no pressure is applied.
