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.

The power door locks do not work. You have to manually lock them. They are suppose to automaticaly lock when the vehicle reaches 5 miles an hour for safety and they do not. One door lock was replaced under warrenty without my knowledge but now the other 3 are not working properly. The mechanic said that this has been a known problem with the Tahoe. It is over $200 per door to replace. This vehicle is not even 5 years old and is under 30,000 miles.

The doors on my vehicle still fill up with water and switches have shorted out. It is an ongoing problem and I have to check for water in the doors every time it rains. The 2010 date is when the dealer first replaced shorted switches in the door. The dealer said it was a rare occurrence at the time, but now there is a major recall for similar problems, but the Tahoe is not included.

While I was driving the air conditioner blower quit blowing and today when I went to a dealer for help he told me how to diagnose the fan relay, but it performed correctly. He also told me that he has seen before on the Tahoe the A/C fan harness has melted before on this type of vehicle.

I bought this vechicle as a used car in June 2010. Before I left the dealership with the car I had to request that one door lock be fixed because it was not locking automatically. That door was fixed (driver side back door). Since then I am having trouble with the passenger side rear door and the driver door not locking on a consistent basis. The driver door seems to lock and unlock correctly part of the time when the weather is cool; however, in the afternoons and during hot weather, the door very seldom responds to the automatic locking/unlocking. After reviewing this website, it is apparent that this make and model of vehicle has been reported to have consistent problems with the locking system that the manufacturer has not been required to address at their expense. Consumer safety laws should apply to locking systems that do not function properly. A known safety hazard is unlocked doors during impacts. Since this vehicle is problematic in this regard, the manufacturer should be responsible for not only providing improved parts but, also, for replacing those parts at the manufacturer's expense.

Hi I purchase 2008 Chevy Tahoe brand new. How I called last year to GM support as for this my door lock problem. They told me we will take care of this just take it to nearest dealer which was 220 miles away from where I live. ( and I was told they will take care of it. ) support dept got me an appointment set everything up. I drove in to dealership they look at all my complains. And got me quote for all the repair needs to be perform. Door lock problem is a know issue to GM I am not the only one who's affected. But dealership told us. That GM would not pay for repair. How would you feel drive 220 miles and get quote in your okay it's going to be $480 per door to fixed. My question if was not going to take care of this repair why would send me to dealership to have fixed.that trip cost me over 300 bucks not to mention all of the frustration involved. Wasted my 1 1/2 days. I have been watching people complaining on edmunds and GM is answering emails. But none of them is getting any help, if GM is not going to stand behind of their product why would respond to emails. This is not done. I happened 2 months after warranty was expired. I bought my truck when GM was in trouble. I don't think that these giant company's care. That does tells me one thing stay away from GM. I would own another GM product in future or ever and pass on this to others. One thing I would like point is that. This door lock problem GM should look into little too closely. This is safety issue. It should recalled and have it fixed immediately without any further delays. Thanks

The passenger door would not lock or unlock, with the remote or by using the drivers door, nor would it lock when putting the vehicle into gear. This is the second time this has happened. So now if you think you are safe, your are not. They put onstar in your vehicle to keep you safe how does that help if you are hi-jacked at gun point" you thought all doors locked when you put it in gear all but the one door that failed because of a poor design. Or your child falls out of the vehicle while going down the freeway and because the lock failed due to poor design. Please help us with these poor designs on Chevy vehicles. I have had nothing but problems with this vehicle. Clunking noises starting now when I turn corners. Dealership states that is normal. Omg! are they insane" I know that is not normal because it was making that noise when I purchased it. Everything starts going right at the time of the warranty ends. Poor window designs the windows are so loose they could possibly fall out when going down the highway.

I have owned this Tahoe for about 6 months now and I am going to replace the second door lock actutor now. I have done some research and this seems to be a chronic problem. This really is a safety issue for several reasons. When the first one failed it was the drivers front door, it failed in an unlocked position. Thats great, we could still open the door. But so could a carjacker! we drove this way for a month before we found that the drivers door didn't lock. Now we are having a similar problem, but now it is the passanger rear door. It is intermittent in it's occurance but it is consistently in the locked position, I am going to replace this now since we know about it, but if we have an accident and one has failed in the locked position and we dont know about it. We will be unable to get our children out in a timely manner. I really think this should be addressed.

I have had all four doors in for repair at one time or another. First it was the rear left door which would not open from the outside. Same door still does/does not open. Second door was theright rear which dropped down when you opened it. Third door was the drivers door which would not open. Had to insert car key to open. Fourth door was the front passenger door which would not open. Each time the door lock actuator was changed. But now I'm still having trouble with the left rear door sometimes opening, sometimes not opening. If I had a child in a infants seat in that rear seat, I may or may not be able to get to him/her in a emergency. I believe this is a safety problem.

While driving on the interstate all of the dash board instruments lost power, the door locks actuated as rapidly as possible, the four wheel drive engaged, and the engine temporarily lost power, & all the dome lights came on. The entire episode lasted approximately five seconds outside of the four wheel drive would not go back into two wheel until the vehicle was shut off and the ignition turned on. This type of scenario has occurred now four times. At one point the vehicle locked itself while shut off with our two year old child in the car stuck in his car seat. The vehicle is going in tomorrow for the fourth time and the mechanics have not been able to replicate the problem. The most recent event was preceded by the rear door refusing to open prior to departure, the headlights flickering, the radio panel shutting off, and when the headlights were switched from dim to bright the door locks again actuated at a high rate, the entire instrument fell dead, the engine briefly lost power & the air bag lights went on and off for about twenty seconds. Once the major failure happened the radio and instrument panel would go dead about every five minutes. Once we reached our destination I shut the car off and went to start it the next day and it had similar problems.

While the vehicle is in motion, the door locks begin to cycle (up and down), the clock resets itself to twelve, static runs through the radio, the console lights (lighting, engine ck, stability control) flicker on and off and the transmission downshifts at will. The effect on the transmission is of particular concern because at highway speeds the vehicle abruptly slows down causing a potential hazard for the driver, its occupants, and others. Once the vehicle ignition is turned off, all power inside, dome lights, radio, etc turn off and the vehicle will not restart until the battery cable is moved back and forth and a connection is reestablished. This is the second time I have taken the vehicle to the dealer and they have been unable to replicate the malfunction.

Tahoe 4WD 8-cyl

  • 5,200 miles
The passenger side factory installed trailer wiring harness is defective because it is pushed in under and to the rear of the spare tire. Accident - coming onto highway 152 with a trailer, which is a left lane entry onto a two lane headed East. Everything inside was working; passenger side signal was indicating properly, but unknown to me the signal was not working on the trailer. As I moved over to the outside lane to give faster vehicles room to pass in the fast lane (left) the car behind me did not see my signal (because it was not working on the trailer, but was on the Tahoe) and had to slam on his breaks and skidded darn near into me. This is really dangerous and is a flaw in the manner in which the wiring harness is squeezed into the tiny space at the rear of the spare tire. I traced all the wiring and it is in the harness since I could not get a current flow reading from the connector/tit that is for the passenger side signal and stop lights. Yes, I did check the fuse and it is fully functional. I fully expect to hear from you since I cannot find a satisfactory place to call Chevrolet; all they want to do is sell you another vehicle. Thanks.

The auto door locks went out on my 2008 Chevy Tahoe lt just after 36,000 miles. The dealer wants to charge me $500 to fix it. There appears to be many GM vehicles with this same problem. This is a safety issue with children in the vehicle. A recall needs to be issued on the auto door locks.

On the last one it was scary I was driving on the highway at about 70 mph when the stability trac light came on and then my car shut down pulled over to the side and the car was dead had it towed to the dealer and the car started with no problem, I refuse to take the car and I called GM tech support and they took over my case with the dealer directly after 8 days at the dealer the GM tech calls me and said there was a bulletin tac #11062498 to replace all battery cables on the car, positive & negative battery cables, starter cables, alternators cables, and cables that go to the main fuse block. I've had my car back now for 1 week and so far it starting good. If my problem still continues to occur I will have no chose but to file for lemon law.

All of the indicators in the instrument cluster sometimes read '0' upon initial startup. Sometimes by turning the ignition off, withdrawing the key, and open/close the door then restarting the vehicle the problem corrects itself. However this procedure may be repeated up to 15 times before problem is corrected or, more often, it isn't corrected.
