I have an 09 that has the same issues and I need assistance. Because the Chevy dealer (Lakeside Chevrolet in Warsaw) can't find anything wrong, they are going to replace the ignition switch because they "think" that may be what's causing the issue. Is replacing this a waste of time? Will replacing this resolve the following issues with my 09 Tahoe LTZ:
1. Periodically, the door locks will cycle up and down and the power on the dash (radio, etc) goes black and the vehicle sputters like it's going to die
2. After that happens, and the vehicle comes out of this state, if you smash down on the pedal the whole thing will happen again
3. Sometimes, the vehicle won't start (nothing happens)
4. The CD player sounds like the motor inside is constantly running
5. The vehicle will completely die when putting the car in park and shutting off the engine (no power....nothing)
We've already replaced the battery and still have the aforementioned problems.

I'm having the same problems with the 'service 4wd' light and transmission going into 4 low.... plus a bunch of other weird stuff, did you ever get a fix for those issues?

I did not. The ignition switch was a huge fail. On the way home last night, the vehicle did some really wacky things when I used my turn signal. That made me angry enough that I disconnected the battery overnight to reboot the computer. I haven't driven it today, so I don't know if that helped or worked.

I cannot tell you what a relief it is to find someone else having gone through the same issues with a 2009 tahoe. the dealership here looks at me like i'm crazy and told me all they could suggest was to replace the bcm. finally took it to a specialty shop and they've had it several times for weeks on end during the past 4 months.
I realize it's been a month since you said that you haven't had any problems, I'm checking to see if the vehicle is still working properly? I'm heading to the mechanic as soon as I hear your response!

I have lodged a complaint with the Office of Defects Investigation (ODI), the National Highway Traffic Safety Administration (NHTSA), and the U.S. Department of Transportation (DOT) via the Safercar.gov website. This vehicle is just to unsafe to drive and the manufacturer needs to recall and repair. It's not my fault the vehicle is this way and we're obviously not the only ones having these issues.

I'm having some of the same problems with my Tahoe. Mines the same year and LTZ...the problem started after I took it to the dealership to have a cracked dash replaced. They ran my battery down so I had to replace it. In the last couple of weeks the screen has turned white 4 times. I have to restart the motor to get the screen to work, all my saved radio stations and all have to be reset. It's at the dealership now. They can't find the problem since they haven't seen it happen. After reading this I wonder if my saved addresses are still ther. I'll look at that tomorrow when picking it up. The tech said it wasn't showing a code so nothing is wrong. Why would the radio/navigation system show a code if they knocked a wire loose or something like that? I've never been more frustrated with them it's like they don't believe me!!!!!

Do you have a reference number or anything for those complaints? Because I will gladly add my name to them. Just dropped my tahoe off at the mechanic again today. It was dead all weekend after an eventful saturday afternoon trying to drive home. sunday brought the same issues. today when the mechanic is open...doesn't do a thing. Still hopeful for resolution, but remain doubtful.

Yes, my 2009 Tahoe is running great. No problems since the specialty auto electric shop worked on it.

Would it be possible for you tell all of us who are having problems, what the specialty electric auto shop did to resolve your issues?

The one thing that most of these electical problems have in common is the GMLAN system. Other than that, each problem will most likely its own unique solution although it will probably be related to correcting a GMLAN component problem. In my 09 Tahoe's case, it was several components that were either a mismatched component or components that needed a software update. The only way to find out is for a qualified technician with a Tech 2 scanner to spend the time to check each component in the GMLAN serial loop to make sure it is, first, the correct component and, second, has its latest software update. Most dealer mechanics are NOT going to go thru this kind of problem solving process. Of course we wouldn't even be having these kinds of problems if the GMLAN system was engineered properly and had better troubleshooting protocols for the "color by the numbers" technicians at the dealerships.
