I have had 2 fail so far but my problem was they failed in unlocked position. I was locking the car but both back doors remained unlocked. sounds like a safety recall GM!!!!! after all you made 1.3 billion in profits last year.

Re: Tahoe Door Lock Actuator Problem, Solution
 

I think they have replaced the old ones with an improved one. Because when mine failed two weeks ago after traveling with passengers trying to pull the handle while the lock is still engage, they actually replaced the whole lock assembly(?).

Re: Tahoe Door Lock Actuator Problem, Solution
 

I asked both GM and my dealer if they have improved the actuator. Both said no.

Judging by amount of repeated failures being posted on edmunds thread, i'd say they are still using that chinese motor.

Re: Tahoe Door Lock Actuator Problem, Solution
 

with the current manufacturing trend, chinese made is the new quality worldwide, from phones, to tv to everything electric, computers, too.

Re: Tahoe Door Lock Actuator Problem, Solution
 

I thought that Gruven sounded familiar;) I think I've ordered there before.
Anyways, If mine go bad I'd like to be able to replace the bad parts. Would you be willing to sell the motors, or give out the manufacturer info?

Re: Tahoe Door Lock Actuator Problem, Solution
 

Bummer. Last week the truck was in for lock actuator replacement. The rear left one was gone. The driver one is dying and I'll send it to you when it does.

Re: Tahoe Door Lock Actuator Problem, Solution
 

I have this same problem for the first time. My truck is at the dealership. It was under the used car warranty, but the dealership is saying I went over on miles. The service writer told me that the sales manager and the service manager were "going to take the night to sleep on it." After sleeping on it, the sales manager decided not to fix it. Clearly they do sometimes handle these problems for people, but not me. I have called GM and the person I talked to said she would definitely take care of this for me. After she got the run around in regards to speaking to the service manager (he was allegedly in meetings) she escalated the claim to a specialist who had the authority to authorize the repair. The specialist called me today (day 3) and basically said she would call the service manager tomorrow (day 4 - why not today) but that she couldn't really do anything to help me. I can't seem to get a hold of Katie (our GM specialist on this board) and the specialist I spoke with said there is no one else to help me, so I guess I am off to the NTSB website too. I honestly believed in fixing each customers vehicle as it occurred, but if they won't, time to let the NTSB create a recall.

Off topic, I also have an issue related to the defective software revision they put in my truck, and they won't update it to the revision that fixes the error with the previous revision. They programmed an error into my truck, and won't fix it?


WOW!

I may just return the truck and sell my trailblazer and avalanche.

Re: Tahoe Door Lock Actuator Problem, Solution
 

What is the error? Once the dealer plugs in and contacts the "mother ship", he is highly restricted in what can be put in.

Any error would be system wide. Care to explain please?

Re: Tahoe Door Lock Actuator Problem, Solution
 

The error is absolutely system wide. Surely you realize that anytime there is a software revision it is essentially to correct an error in the previous version, even when they call it a "customer enhancement." The situation is still that the previous software was "undesirable."

In this case, the error is related to maintaining a charge in the 12 Volt battery. when we talk about reasons that the truck will switch into battery mode or ICE mode, one variable that was not previously considered was the SOC of the 12 Volt battery. It was always assumed that as the ICE ran in the normal course of vehicle use, the 12 Volt battery would remain charged. In some cases that does not happen, and multiple errors can occur ranging from the stabilitrak off on the DIC to the full set of errors that goes with a dead 12 Volt battery.

This is what was explained to me by the woman at GM customer service. I subsequently searched for info on it and found an extensive write up on this issue on this site, and more concise write ups on other sites.

Re: Tahoe Door Lock Actuator Problem, Solution
 

Did someone tell you that the ICE needs to be "running" to charge the 12V system?

If so they are flat wrong. In fact the 12V system voltage increases in auto-Stop.

Don't believe me? Plug a volt meter in the 12V cig ltr jack and watch. The SOC of the 12V battery has absolutely nothing to do with ICE on or off.

Hi Winchester_Fire,

I have sent you a direct message and am catching up on this thread today (many apologies for my delay!), and I'm so sorry to hear about your frustration. I look forward to investigating on your behalf and working towards a resolution.

Best,

Katie

Re: Tahoe Door Lock Actuator Problem, Solution dang!
 

I had a problem that was fixed under warranty and now I am on vacation and wouldn't you know it, my pass. side failed. I may be sending you one to keep for swapping as I won't replace it till I get home next week.

Re: Tahoe Door Lock Actuator Problem, Solution
 

Hillbilly,
I am not sure that anyone told me that, or that I said that. Perhaps what I said could be interpreted to mean that. I don't recall it that is true or not, but I can check. Putting a volt meter on the cigarette lighter would not tell you much. First, the values would be inaccurate due to the resistance of the 20 gauge (off the top of my head) wires that feed them. If you were just looking to see if the voltage was higher or not, it would not prove anything. Unless GM manufactured a vehicle that had 12 Volt outlets that only got power when the vehicle was running on ICE, then there would have to be a way to power the outlets when under battery power. the obvious answer would be to take power from the hybrid battery and put it through a voltage regulator to give 12 volts to the outlets. That would certainly result in a higher voltage than a typical ICE would give. With a running engine, a typical ICE would power the outlets through the alternator more than the battery (when running). The other two options would be that the power is derived from a generator on the electric motor or an alternator on the ICE. Each of those would have their limitations. An unlikely setup would be similar to that of an outboard marine motor. Anyway, I will find out and let you know. In the end, the software update did not fix the Stabilitrak light.

Re: Tahoe Door Lock Actuator Problem, Solution
 

How about selling just the motor or posting a source for those of us willing to repair them ourselves? Not that big a deal to drill the rivets out then tap and reassemble per my post and video here:

Re: Tahoe Door Lock Actuator Problem, Solution
 

Yes pls email paul@gruvenparts.com

Keep in mind we had to design the new motor for increased durability, then buy 1,000 ea CW and CCW rotational versions of these since its a special design which is not available anywhere, so I had to invest a lot of $ to do this. We also had to buy a mill run of the gear since that is special, too. GM made nothing simple about this lock actuator and definitely did this to make you keep buying new 1s.

Re: Tahoe Door Lock Actuator Problem, Solution
 

you will need to apply as vendor to advertise on this site? FYI!

Re: Tahoe Door Lock Actuator Problem, Solution
 

Understand all that, but how about responding to my e-mail about what you will sell the motors with gear for to those of us willing to undertake the repair?

Re: Tahoe Door Lock Actuator Problem, Solution
 

I must be having email issues, can you please resend it - Paul@gruvenparts.com, please also cc the shop email - pi2060@yahoo.com

We have had a server issue and some emails apparently did not come through.

Ive updated the original post in this thread with many more part numbers. This issue is very widespread, it affects most GM products from 2007-2014. Please read the 1st post on this thread for all details.

Re: Tahoe Door Lock Actuator Problem, Solution
 

Im also curious to know if the 2015 have started having this problem...

Re: Tahoe Door Lock Actuator Problem, Solution
 

Anyone driving a 2015, and any issues yet with faulty door locks, or cracked dashes ?

I have the 2015i escalade platinum. Hopefully no door lock actuator problems yet.
