    "Service 4WD" - Master Thread

    My Yukon Denali has been in service 3 times for the "service 4wd" issue and still no fix. What the dealer told me is that the problem is coming from starting or turning off your car while in the "auto" position. He said you can switch to auto after you start as long as you switch back to 2 wheel...

    165 miles and I got a service 4WD message

    I'm sorry to hear about your situation. It seems as if you have been very patient throughout this whole process. My Denali has been in service 4 times total and 3 times for the service 4wd and still no fix. I am about to start the lemon law process since GM does not seem to care about us...

    I have been running in auto since it is the rainy season in Florida now and heavy downpours appear out of nowhere. I dropped mine back off at the dealer today. I will post any updates as I get them. 5500 miles and this is the third time in service on a car with a 74k msrp.

    I picked mine up yesterday and "service 4wd" just came back after about 50 miles of driving. It feels like it is stuck in 4 hi. Back to the dealer Monday morning. Very frustrating!!

    Today is day 3 in the shop for mine and I have not heard from the dealer yet. I think I want to get in line on the "buy back" program.

    Did they offer this or did you request the buy back? Did they even determine what the problem is? Mine is in service now for the same issue.

    Dropped mine off at the dealer this evening so I will post as soon as they fix. I also asked them to fix drivers seat right this time and also asked them to look at exhaust rattle on cold starts. All of these problems on top of the 8spd tranny coming out a few months after I bought mine is a...

    165 miles and I got a service 4WD message

    I just got a "service 4WD" light on my 15' Denali with 5400 miles. Very frustration after I just fixed my drivers seat with heater hose and clamps after dealer failed to fix. I have had a 07' Avalanche, 09' Denali and a 11' Denali and never had any problems. Very dissapointing.
