Sorry to hear that. They have no respect for their customers.

Had the problem on Feb 2 and software was updated that date. Anyone whose software was updated 2/2 or later have the problem recur?

need 2WD to 4WD Auto explaination

I need to know when I put it in Auto is that for automatic switching from 2WD to 4WD High or is it for some sort of all wheel drive mode? I bought the car for safety for independent wheel for driving on ice as I need it. I have done the lemon law once before on my BMW I had. Out of the 2 years I owned it 1-1/2 years it was in the shop. I love this my Tahoe but if I have to keep taking it back for updates I guess I will use the lemon law.

PS we were on our way to Las Vegas a month ago and I had it in auto for 2 months with nothing happening. My husband had to ask if it ever switched in since the last fix and I said it was doing great. Low and behold we stopped in Kingman for gas and when he turned it back on it fell into 4WD "low" and we had to crawl to a dealership to get it fixed again. What a pain in the ass. So not safe when traveling either.

So the Auto function engages the front differential but keeps the clutch pack in the system engaged until the system senses rear whee slip. At that point the clutch disengages and sends power to the front wheels in addition to the rear. In 4hi the front get power all the time and the 2hi the front never get power and, because less of the drivetrain is engaged, you'll save a little bit of gas as compared to auto.
