Chevy Tahoe Door Lock Problem



  • IF you scroll down through these posts on chevy tahoe door lock problems, one man fixed his and he told me how in the posts. I haven't done my yet, they work sporadically and I roll the window down vs. Climbing over seats. Hope that helps.
  • Had the same door lock issue. Thank goodness three of the four failed under warranty. When they were fixing the third one ( three seperate trips) I asked the dealer to go ahead and change out the fourth because there was an obvious defect. They would not do so. Low and behold 10k miles after the warranty expired the fourth one went out and same ol' $400.00 story. I havn't changed it out yet becasue i have not been able to swallow the issue yet. I bought an 08' LTZ 2500HD the same year and only one of the 4 has gone out so far. Crossing my fingers. I wa certainly dissappointed that they wouldnt cover the 4th under warranty after teh other three failed under warranty. I have a fleet of 80 pickups, 50/50, ford/chevy. Still no consideration. I am not sure which one i will reconsider next time the manufacturer or the dealer.
  • I think I'll try to replace my door locks on my own....after I come to grips with the expense! Let's hope its not too involved. Has anyone ever tackled this job before? :mad:

    Haven't ever had to do it on either of my Suburban's (knock on wood). But have replaced them before on my Vette, and a couple on Chrysler T&C. Take off the inner door panel.
  • Hi, I am in the military stationed in Germany with my 2008 Yukon. I only have about 24000 miles on it and already one of the door actuators has failed and a more are sticking. It is to the point that sometimes I have to enter the car from the front passenger side. While my vehicle is still under warranty, I was told by the dealer I purchased it from in the US that the warranty would not be honored in Germany. There is a Chevrolet dealership in the town I live in, however. Is there anyway I can get this issue resolved under warranty here? It sounds like at least a $1200 problem, if I can even get it done. Thank you for your time.

  • I will send you an email on this. Thanks for the response!
  • I recently purchased a 2008 Tahoe and am rewarded with 2 doors (both left side doors) that now refuse to auto open. Should have consulted this forum before buying or stuck with my gut and purchased foreign. I loved my 99 Tahoe with 154,000 miles and am sick after reading this forum. Sounds like the manufacture should have addressed the problem a long time ago. Keep this thing going and maybe GM will get the message . Ralph

    I purchased my 2008 Tahoe in Oct 10 with 37427 miles; at 42000 miles (January) the front 2 door locks stopped working. In March I took it to the dealer to have the recall addressed and the day before I was to leave it the back passenger door lock stopped working. I was quoted by the dealership a price of almost 900 to have the three doors fixed. This is my first Chevrolet Tahoe and I thought I was upgrading from my ford explorer which had almost 100,000 but it never gave me any problems. Have any notices been issued by GM to address this problem or offer some kind of discount to have these locks replaced?
  • :) :) :) We'll no longer have to worry about Chevy's poor service and unreliability... Got rid of the 08 Tahoe!!!! Happy, happy, joy, joy!!!!!!!!

    I would like to get more specific information from you regarding this issue. In order to do some further research, it would be very helpful to have the VIN, current mileage, full name, address and best contact number for our records sent to me in an email. Any assistance you can provide would be greatly appreciated. Thank you.

    Have you spoke with a dealer about your concerns?

    We’ve got an 08 tahoe hybrid with 26k miles still under factory warranty and all 4 door locks have quit. We have had drivers front and pass front repl. under warranty, now the back 2 are dead as well.

    GM customer service : Christina, Caron, it is encouraging to see you posting on here (if you are not just bots) and I hope you will follow through. Yes I have informed my dealer (Jim Ellis, Atlanta) about this issue and I will remind them again when I bring it back in for the next round of door lock replacements. They told me they are breaking on every Tahoe (and many other models) and there was no better version to replace with. You need to make the engineers at the tech center in Warren aware of this issue ASAP and have dealers start swapping in a better mechanism during the repairs. Ive got 3 kids and driving down the road with unlocked doors is very dangerous. It’s a deal breaker in a $20k car let alone a $50k car. I would be happy to go over this with you or any GM engineers in detail as Im an automotive and aerospace mech. Engr too. Please feel free to contact me directly. Paul at gruvenparts dot com. I can provide my VIN, ect..

    Aside from the door lock issue, this car has made me proud of GM. The fit/finish on the body and interior are good. The ride is excellent considering its very low tech body on frame. The hybrid system works quite well and seems to net us about 18 mpg in our mostly city driving. Comparitively, the Ford Expedition of same year got us 12 mpg so this is a ~30% improvement.

    Fix the door locks and its almost worth the hefty price tag. I couldn’t stand the thought of looking at an Odessy or Sienna and thankfully this vehicle has done us well. Ive got faith in GM but I will be renewing the warranty next year.

    We have a 2009 Suburban that we bought last May 2010 (Certified Used Car). When we first
    looked at the vehicle I noticed that the right rear door lock did not work and told the salesperson. We ended up buying the vehicle a few weeks later and they apparently had fixed it.
    Starting in December the the right rear stopped working, then soon afterwards the front right, and then the rear left. So only the driver's door lock works now. We drive a lot so it was out of the original warrenty and certified used car does not cover it. Currently have 60,000 miles, started going out at 38,000 miles. Finally took it todealer to have it looked at as it is a pain with two kids in car seats to have to roll down the windows to unlock the doors and is dangerous when they do not lock. Anyway, got the estimate and dealer wants $850 to fix the three and got charged $75 to tell me that.

    I asked the Service person if they did a lot of this lock repairs and he told me "you are the third one that has came in today." Wow was all I could say.

    I think Chevy needs to recall this.
    I have turned it in to the NTSB as a safety issue. They recomend that anyone who has the problem do the same. There are two many of these problems with a too high cost to fix for GM to not help out.

    I also contacted NHTSA to report this problem as I believe it to be a safety issue as well. Here is the contact information and I encourage all to do the same. If you go to their website you can submit an email directly, or if you prefer, call them.

    Here is my email :

    Dear NHTSA :

    I own a 2008 Chevy Tahoe Hybrid with 26k miles. The front door lock actuators failed at 12k miles and were replaced under warranty. The rear door lock actuators failed at 25k miles. The faulty door lock actuators prevent locking or unlocking of the doors from the drivers seat. As I have small children, I feel it is a safety issue to drive with unlocked doors. After researching this issue I’ve discovered the problem to be widespread on a number of Chevrolet vehicles. Please reference the following internet forum discussions :

    I suggest the NHTSA look into this issue and mandate the installation of a more reliable door lock actuator. Please let me know how I can be of further assistance in this matter.

    FYI - I did receive a call and email from GM regarding my post shortly after making it. The representative who called provided instructions on how to schedule a service visit at the dealer. I already know how to do that, what I was asking for is a FIX to the problem, not merely another faulty replacement door lock actuator. I was contacted again shortly after via email by another representative who said :

    The best way to make GM aware is to have a case set up with GM Customer Assistance.
    Either you can call and do this or I can do it for you. Please let me know how you
    would like to proceed.
    GM Customer Service

    I asked her to set up a case for me regarding this, will let you know if anything comes of that … c’mon GM, fix this problem. This truck is great but we need working door locks!

    Thanks for attaching all of the NHTSA contact information, I should have done that. Hopefully all of those that have the same problem will turn this matter in. If enough people act, it will get taken care of.

    I also love the Surburban, in fact it is the third one that I have owned and the others did not have any major problems and I drove the other two for over 200,000 miles. We traded a Toyota Sequia in when we got this new Suburban that had 175,000 miles and it never had one problem and the certified used car warrenty was 100,000 miles bumper to bumper. We decided to give the suburban another try for the room.
    Just can't really stomach paying $1,000 to have the door locks fixed.

    I just got back from my dealership - to have my door lock fixed (twice now). Luckily I'm under 36,000 miles. GM definitely has an issue that should be taken care of. May I suggest some type letter to all owners stating that GM will take care of these locks up until 72,000 miles --- or else replace all locks with something DECENT! Other than that - I love my 2008 Tahoe (except the overdesigned auto temp control). PLEASE give us basic slide controls on the higher end models. I need simplicity - not confusion. :)
  • a2ta2t Posts: 19
    Glad it was at least repaired under warranty. I received a email back from NHTSA saying they are looking into it. Will update when I hear more.

    GM reps : do you have anything to report to us regarding switching to more reliable door lock actuators yet ?

    RE : auto climate control – I think its kind of nice, whats difficult to understand ? Set it to temp, chose A/c or no, Aux (rear) or no, pretty simple (when its working correctly). No ones doing slide cables anymore, but yes those are simple to work with. You might need to step back a few decades (or a few more decades if it’s a Mercedes)

    Anyone see the latest from consumer reports naming Tahoe hybrid the Worst Vehicle for 2010 ? I can see beating up on it from a price standpoint, the truck is $10K too expensive, but its not a bad vehicle. If fuel hits $5/gal it will make a lot more sense over a 12 mpg Expedition. Hope GM gets the nagging issues taken care of…

    If you have not already done so, you should turn it in to the NHTSA using the links in the posts above. It is a short process.
