I'd posted in another thread that was kind of brought back from the dead, but I wanted to start my own because from reading through all the different forums, not just tahoeyukonforum.com, this seems to be a more common problem than most might realize. Mine is 2011 Yukon Denali, bought new with 5 miles on the ODO in February of 2011. So, here is my issue:
Lights flicker at night, and sometimes the whole electrical system shuts down and "reboots" (stereo shuts off and comes back on, guage cluster goes blank and then comes back with all kinds of warnings like airbags, etc). The thing runs fine through it all and the engine doesn't skip a beat. I found by mistake that if I touch any of the window buttons in the wrong way (like if windows are already up but I hit the UP button), it shorts out everything almost every single time. And I don't mean "hold down" the button; I mean just touching it once real fast. Funny thing is that it won't do that at idle sitting still. The car has to be moving, and then it will do it every single time. What a piece of crap. Off to the wild goose chase of a dealer not being able to figure it out. But at least it does it all the time now so they'll be able to replicate the problem. A few months ago, it was intermitent. I made an appointment once and it stopped doing it about two days before the appointment so I cancelled. Fast forward a few months to now. Now, it does it every time I drive it. And at night, it's a safety issue for sure. I hope it doesn't stop as soon as I make the appointmet this time.
I'll update the dealer's response and attempt to replicate/fix as soon as I take it in.
Anyone else having these issues here?
