Vehicle driver side back door would not unlock using remote control. Cost over $300 to have Chevrolet dealer fix. Now in Feb 2014 with 7600 miles it started not working on the passenger side back door stop working with remote control. All other locks would open but not the rear door at that time. It appears their are issues with these door locks. The door locks will only open manually when they fail which is a pain due to the size of the vehicle.

Our actuators failed on 3 of my doors of my 2009 Chevy Suburban. If you use the remote only the drivers side rear door locks and/or unlocks. If you use the unlock/lock power button only the drivers side rear works. You must use the key to unlock the drivers door and you must either open the window to manually unlock the other doors or reach across the car to unlock the passenger side locks. We contacted GM and they sent us to have a diagnosis done which cost us $99. They estimated the cost to be $900 and told us we were responsible because our warranty ended at 36,000 miles. This is a safety concern. In an accident I wouldn't be able to get to any passengers including my children nor could emergency personnel. I could easily be car jacked or have my belongings stolen due to the locks not working. If my small child choked or had a medical emergency I could not reach them. I watch stories every day on the news of awful people taking or assaulting women by breaking into their cars and hiding in the back seats. This car cost well over $50,000 and this should be a safety recall. There will be a tragedy if this is not fixed.

The door lock on the driver side second row would not unlock when the car was parked either by the inside unlock mechanism or the remote control door unlock button. Had to manually unlock in from the inside which was difficult because of having a carseat back there. Should there have been an issue where I needed to get my child out in a hurry, there could have been a major issue.

The door locks intermittently work. Seems to happen to a lot of people. Safety issue. Can't get in or out of vehicle. We had one fixed and now all of the doors are doing it. Sometimes the car locks itself.

The lock on the passenger side door stopped working by the unlock button or the automatic entry button. Had it repaired to the tune of $500. Now both back door locks need replacing. Dangerous if kids unable to get out of the car.

About a year ago the rear passenger door lock wouldn't work, now all door locks will not lock or unlock with remote or switch. Also will not lock/unlock when put into gear or back into part. Locks move slightly when you push the button but will not fully engage or disengage when manually pushed. No recall data available but I see many complaints.

Door locks no longer working on driver door, front passenger, and now rear passenger. Dealership says all three need replaced. Driver door went first, then front passenger, and then rear passenger. I have found several postings related to multiple door lock failures - not just single locks, but many cases of 2-4 locks failing on a single vehicle. Locks are very expensive to replace (especially in quantities of 3 or 4) and represent a safety issue if the doors cannot be secured.

The contact owns a 2009 Chevrolet Suburban 1500. The contact stated that the front passenger and rear driver side doors were defective and would only open when pulling the latch manually. The vehicle was taken to the dealer but was not repaired. The failure mileage was 57,000 and the current mileage was 58,600. The VIN was unavailable.

2009 Chevy Suburban currently has 57,000 miles. Starting around 30,000 miles the automatic locks started to stop working. Now the passenger front, passenger rear, and drivers side read door locks do not work. They do not lock or unlock while pushing the switch on door or using the remote. Took to dealer today and was advised that the cost to repair would be $875. Researched the item and it seems to be an ongoing and frequent problem over the past few years, yet GM is not doing anything about it. This is a safety concern to those of us who have children as the doors to do not automatically lock like they are supposed to and they can be unlocked while the vehicle is in motion. I think that this is an issue that needs to be investigated due to the high number of complaints that have been made, the high number of repairs that have taken place for this, the high cost to correct the problem, and the safety issue that it can cause.
