Rear passenger door electric lock actuator failed resulting in no way to open the door without manually unlocking it from the inside. In the even of an emergency, there would be no way to open the door from outside of the vehicle or from the lock switch on the driver door. In addition, there is no key lock on this door from the outside. I have learned that this is a very common problem on 2008 Chevrolet, which has cost consumers a huge amount of money in addition to subjecting them to serious safety concerns. I was the victim of a theft when a passenger did not manually lock the door and several days later when I was parked in a parking garage someone entered my vehicle and stole personal property. This would not have occurred if the lock actuator had functioned properly and locked the door when I locked the others. To date, Chevrolet has acknowledged this issue but refused to do anything to correct it without an approximate charge of $300 - $400 per door.

Power locks are failing for second time after replacing. The actuators do not last over 2 years. Each door costs $300 to repair. There are thousands of posts on the internet with this problem in multiple models and years. This needs to be a recall.

This is the 3rd time this happens to my vehicle and I get it repaired. When I got my Tahoe with 0 miles it already had this problem and I had it fixed, I thought no big deal of it. Then with time I find out it is a common problem with my vehicle. I did some research and this is a very common and pricey problem. The door locks on my Tahoe go out, they don't go up or down automatically and this is an issue to me because I have children in the back with an unlocked car. Three of my doors are currently out and I don't have $940 to fix it. My passengers are not safe because the door locks are a major problem. Please help us out!

The door locks have gone out on my 2008 Tahoe approximately 6 months ago. Our children cannot open the doors to get in our out of the vehicle. The only door that will currently work is the driver door, which only works with the key. The Tahoe has a factor installed alarm system / key fob system, and does not control the doors to lock or unlock. You have to use the key to unlock the driver door, then manually open the passenger and rear doors from the inside, as well as manually lock them from the driver side.

The locking mechanism on my Chevy Tahoe 2008 ltz no longer works on the passenger side door. The electronic lock/unlock door mechanism no longer locks or unlocks the passenger door as well as the key remote no longer locks or unlocks the front passenger door. It sounds like from reading the other numerous complaints regarding this issue I can expect the rest of the door locks to quit operating at some point. This is obviously a real safety concern.

The company I work for purchased four 2008 Tahoe new. All have had door lock problems. Mine just happened on both driver side doors and it cost $741 to have fixed today at Chevy dealer. I believe the other 3 Tahoe were under warranty at the time, but not sure. The Tahoe I drive was not under warranty. As others have said, you cannot unlock the rear doors since there is no key, and the manual button is not near the pillars so you cant reach it from the front doors. Its a bad situation if you needed to access the rear doors.

I have taken my 2008 Tahoe ltz to the GMC dealership multiple times to repair the door locks / outer door handles. I have had two of the door locks replaced because they will not unlock when I hit the unlock button on the doors or the key fob. This is a major defect in this vehicle. It is a safety conern because I have a small child and I am afraid if I were to have an accident and I try to unlock the doors they will fail and I will be unable to get my child out without crawling over the front seats to manually unlock the lock. The same with the outer door handles breaking. I have had two of those replaced. I had to crawl over the passenger seat at one point to be able to get in the vehicle until I could get it to the dealership. I have searched the internet and see there are several complaints about these issues, yet there are no recalls. Please help us.

To whom it may concern; I am writing because I have had similar problems with the door locks on our 2008 Chevy Tahoe. We have had a problem with the door locks in the past as we have had to literally climb out of the window to get out of the vehicle. We have been experiencing problems with the door locks again and took the vehicle to the Chevy service this morning. Their customer service rep said the charges are $300 plus. The vehicle has only 84,470 miles. This problem is huge considering that you can not get out of the car once a lock completely fails in that you have to climb out of the window to get out of the car. Also the front driver side window has been making grinding noises when it is used open and close. As this is also another similar issue that others have complained about. My question is why is this so hard to recall and fix" being that we spent good earn money to buy this vehicle and very much loyal to Chevy's vehicles. What happened to taking care of your loyal customers" a recall should be indeed initiated to settle these repeated issues with these vehicles so customers can feel that chevorlet is indeed loyal to their customers as we are loyal to purchase their vehicles. Money isn't everything however taking care of your customers can go a lifetime. It starts with the customers first.

Failure of all four power door locks on my 2008 Tahoe. At almost exactly 3 years and 30,000 miles of ownership, the door locks of my, purchased new, 2008 Tahoe ltz began to fail. All four locks failed within 12 months of each other. The vehicle had less than 40,000 miles and four years of service at the last and final (4th) failure. Concern: (#1) there is only one manual keyed entry located on the vehicle which is the drivers door. In the event of an emergency and total electronic lock failure, the only passenger door access would be through the drivers door utilizing the key and manual lock/unlock feature. If the manual lock were to also fail, there would be no way to gain access to the vehicle through any of the four passenger doors. Restricted access to the vehicle could cost the life of a child, adult passenger or pet trapped in the vehicle. The system could be designed safer with a redundant manual lock located on another door. Additionally, the electronic locking mechanisms currently installed are inadequate and unsafe. The common failure of these systems eliminates the argument of electronic redundancy for the system since the installed product is faulty and unreliable. Why should we be forced to accept these unsafe products/designs on our vehicles? concern: (#2) the cost of replacing a lock has been quoted between $250 to $450 per lock from different facilities. The pricing may influence a generally safe mined person to postpone a repair which impacts the redundancy feature of the electronic system. Note: These locks typically begin to fail immediately after the warranty expires. And, GM corporation is unwilling to help with the cost and wasted time to deal with the issue. Further investigation by the NHTSA is warranted and I feel a recall should be mandated.

To whom it may concern; I am writing because we have problems with the door locks on our 2008 Chevy Tahoe. We have had a problem with the door locks in the past as we have had to literally climb out of the window to get out of the vehicle. It happened while on a boat ramp so it was an incredibly memorable event. We have been experiencing problems with the door locks again and took the vehicle to the Chevy service this morning. Their customer service rep called us to let us know that all 4 door locks needed to be replaced. The charges are $350 for the front doors and $250 for the back doors. Needless to say we are not happy about having to pay for any additional door lock work on this vehicle. The vehicle has only 70,000 miles. This problem is huge considering that you can not get out of the car once a lock completely fails in that you have to climb out of the window to get out of the car. We request that a recall be initiated as soon as possible.

I currently own a 2008 Chevy Tahoe. Today 1-17-13, I had to have the power door lock actuator replaced for the 5th time on this vehicle. Every door has been affected at least once with today being the right rear door having to be replaced for a second time. From what I have read numerous times online, this seems to be a recurring problem for the GM SUV products starting with the 2007 model years. GM has yet to address this issue with a recall, however I feel as well as many other owners of these vehicles that this could cause a serious issue if the vehicle is hit from the side or a water related accident occurred with the vehicle being submerged and not being able to get out. 1 or 2 instances in a 4.5 year period I could understand but 5 in a 4.5 year period involving every door is not a coincidence. The replacement cost is well in excess of $200 and as such I can understand why GM would be reluctant to act. Does it have to take a death or 2 for GM to realize that this is a serious issue and needs to be addressed. If you build a vehicle such as this and charge in excess of $50,000, then I as the purchaser have every reason to expect that these types of issues would be resolved by using quality parts and not junk. Please investigate this issue and you will find a whole lot of customers of these products who are highly upset and want something done to resolve this serious issue. Thank you.

First problem was the vehicle would not crank. The vehicle had to be jumped off and then it cranked quickly. While driving the vehicle, the window control, speakers and heater would go in/ out of operation. The speakers in all four doors would go out then come back on at different times. Sometimes they would work all at once, other times one, two or even three may come on and off. The heater would come on blowing some times then cuts off again and again. The heater blower would also blow at one speed then blow at another speed without anyone changing the settings. The window controls will make the heater blow stronger, then when the window control is released it will cut the heater off. The rear passenger window controls will not work at all. The rear passengers also can not get out of the vehicle. The vehicle has to be open from the outside for individuals sitting in the second row seats. The only control that will work the rear passenger windows is the driver side control. The vehicle also has a light smoke smell coming from the vents. The passenger side door in the front will open for the passenger sometimes then at other times someone will have to open the door from the outside. The vehicle will not crank back up after been cut off, it always has to be jumped off. The battery is drained everytime the vehicle is sitting down and not being operated. The vehicle was taken to the dealership numerous times without being fixed. GM corporation was called and I was informed a recall was on some vehicles but not others. I was told that my vehicle was not listed as one thou. The dealership checked my vehicle and informed me that my vehicle didn't have any issues but then on a second request they informed me that my vehicle had a bad battery and was having firing trouble. They also informed me that I was not covered by my warranty.

While driving the vehicle, the stopped blowing and then begin to start blowing about 20minutes later. The vehicle also begin to smell of smoke at one point. The control buttons for the rear passenger windows stop working. The speakers begin to go in/ out of play and the rear windows would only work from the driver's door control. The window button then begin to control the level that the hat would blow at. Door controls stop working for some doors at a stop and the door would only open from the outside. After starting the vehicle, the door would then begin to work again. Electrical controls for the child proof were inoperable for backseat passengers. Speakers going in/ out of play while driving and the heater blower also going in/ out of working condition. Window control would make the speakers come on/ off at times. Battery would be drain from electrical problems and need a jump-off to begin back working. Battery, starter and alternator checks at dealership were perform with no problems noted but vehicle would still do unfamiliar things such as heater blower, speakers and control switches performing at their own times. Heater voltage draining the battery and also causing electrical problems. Vehicle will not perform as expected due to malfunctions of electrical modules and unknown control modules affecting the heater, speakers, windows and doors.

Drivers door and back hatch will bounce back open and not catch and then the door lock will not unlock to open the door by remote, door panel lock or by hand trapping person in the vehicle. Spoke to GM, they know this is an issue but unwilling at this time to put out a bulletin or recall.

After vacating the car through the front driver's side door, the electric door locks on the rear doors did not operate while my grandchildren were in the Tahoe. The doors would not unlock either with the fob or the electric switch in the Tahoe. This incident was very scary and could have been serious. Fortunately, I was able to reenter the Tahoe through driver's door, start the car, lower the rear windows, manually unlock the doors, and remove my grandchildren. Had this been an emergency, serious problems could have occurred. As a result of this problem, which has recurred many times, I am not willing to drive with my grandchildren in the Tahoe, unless an adult is available to accompany them in the rear seat.

5/31/2011 driver door lock actuator failed, door would and alarm would not set. Fixed under warranty. Rear left and front right failed within a year. Both were replaced at no charge out of warranty at 45000 miles, approx. October 23 2012, rear right lock actuator failed. Not sure how long it was not working, but the vehicle was parked and driven with the door unlocked, unknown to me. I find this to be a very unsafe condition, and with the number of complaints on this issue I'm surprised no injuries have been reported. Thefts, kids opening moving vehicle door, carjacking are all things that come to mind. Why is there no recall? clearly a safety issue, and not isolated to just a few vehicles.

Door locks on passanger side faulty.

1. door locks failed. Have been replaced multiple times. As a result, my [xxx] old baby got locked in the car in 100 degree weather in August. It continues to be an issue and often I have to resort in climbing through the back tailgate. 2. stabilitrack and traction control lights flash. Sometimes after these lights flash, my vehicle will go into "reduced power mode" on its on which is very dangerous going 65 mph or pulling out from somewhere. 3.my wipers work when they want to...ever since the two recalls Chevrolet released, the work intermittently when they want to. 4. major electrical issues with these vehicles....I have replaced the battery four times and something continues to drain it.

2008 Chevrolet Tahoe 4X4 V8 5.3L, check air bag light came on during a routine drive and no bags deployed. Checked with dealer and they wanted $300 to clear fault code B0083 for a front sensor. Looked online and many other GM vehicles have had similar issues with this safety related device. Since it is of safety concern and there has never been an accident with the vehicle I would like the NHTSA to investigate GM airbag sensor component failures of vehicles with less than 150K miles.

The doors fill with water after it rains. The water doesn't drain and begins to smell like mold in the car. Now, the electrical system for the windows and door locks is acting strange.
