165 miles and I got a service 4WD message

Yeah, we actually tested that scenario again. We turned the car off in 4auto and put it on. Well the problem didn't happen again. If it happens again I will open a case with GM.

No I said use in 4wd and before you turned off put back in 2wd. And make sure is in 2wd. And after you start the car put back in 4wd, works for me or maybe I'm lucky enough.
I have 300 + miles after last reset use every time.

Seems like a real hassle to have to remember to put in back into 2WD every time you turn the car off.

As I said, I tested this exact scenario with the dealer and it did not happen. I also have shut down my engine on Auto twice myself and it didn't happen anymore. Whatever they did to reset the computer seemed to have rectified it... for now.

 

[humer101]

They working on that for sure.

I just picked up my new LTZ yesterday. I love the retractable running boards and the new wheels, but haven't had the opportunity to run it in auto as yet. Mine was build in mid September so I have fingers crossed that it will be fine. Was happy that GM bought the original one back and stepped up to the challenge.
