I have possibly a relasted/similar problem. Just traded our 07 Suburban LTZ for an 07 LT (purchasing this used vehicle was much cheaper than buying out our lease on the LTZ). The new LT we picked up is loaded with all the same options as the LTZ but is simply missing the chrome exterior trim package... no biggie.
Anyway, after leaving the lot we noticed the "Service Rear Park Assist" message, which the dealership now says that our Platinum extended warranty plan does not cover. In addition, when you turn off the vehicle while playing a DVD, the rear LCD screen does not turn back on when you turn the car back on. The only way to turn it back on is to eject the DVD and start it all over again... and the kids have to suffer through the previews all over again! Further, the steering wheel controls only scroll through the same Fav page of radio channels, not through the entire 6 pages worth of saved Fav channels.
Anyone experience similar issues? Think this is related to the fix described on the previous posts?
We are absolutely livid with the dealership (Harold's Chevrolet, Angola, IN -- a 3-hour drive from our house in Indy!!), as they have told us that the "Manual" says this is how the system is supposed to operate! Give me a break!! We just traded the identical vehicle for this one, and the other one did NOT operate that way. Further, they tried to BS us and tell us that "some" vehicles might be made differently from others... OK, "whatever"! Clearly there is something wrong with a connection somewhere or with the brain of this system it would seem.
Any ideas?

I don't know if this is related to the same problem my tahoe has but my dealer replaced the ignition switch and the radio including the entire wiring harness to the radio. This has been several months ago, so far I have not had any problems but in the past it has gone up to six months without acting up. The reason they replaced the radio and wiring harness is because all of the audio in the vehicle including the rear parking assist beeps are controlled through the radio. You might mention this to your service department. Hope this helps.

For what it's worth and to document the problem, I have an 05 Tahoe that just had a complete shutdown while driving home last weekend. I tried to jumpstart and did not work. I had it towed to my mechanic who's been trying to find the problem. He installed a shop battery to see if he could get it started but that did not work. He said he was able to get the foglights on but nothing else. It sounds like a complete electrical mess. At this time, all I know is that I need a new battery. I have no solution yet but wanted to get it documented. I will continue to monitor this forum for any assistance.

....and for what it's worth....a complete electrical shutdown is usually much easier to troubleshoot and fix, than a sporadic/intermittent failure. Not that I'd wish a failure on anyone, but if you had to have one, your's is the kind to have (except for the required tow).

I have an 01 Tahoe that has been having complete electrical failures for years now. I rebuilt the Positive battery cable end and that helped for awhile. Now it is back to intermittent failures again. These COMPLETE electrical failures usually occur at low RPMs but sometimes have happened at highway speeds. My mechanic cannot figure it out. Anybody please let me know if you have found a solution. Love the vehicle excepting this problem..... and it's a big problem!

Did you read thru the old posts here? This topic is ringing a bell that I've read before on one of these Edmunds forums on either Suburban or Tahoe. Somehow I remember reading something about a particular ground post that either gets loose or needs to be cleaned off.
Seems like 3 -6 months ago timeframe, but I could be way off.
