Should I avoid them for repairs or just tell them to reflash the transfer case? This is crazy to still have this issue

I have the last update yesterday they do for me, I just bring for regular service and they update with the latest version.<br /><br />
Hope work now.<br/><br/>

I have a 2015i Yukon Denali and today was my day to join the 4-wheel drive problem family-848 Miles<br />
Got up and hopped in to to work and went down the drivewy 35 feet turned left to go down the street and felt the steering jerk like it does when in 4 -wheel drive on pavement<br />
Pulled over and checked the position of the switch which was in 2 wheel drive<br />
Looked at the dash and saw service 4 wheel drive<br />
Drove a little and found it was truly in 4 -wheel drive high<br />
Made an appointment for Thursday<br />
I'll let you all know what happens<br/>

This guy post this before in the 4wd master thread. Good luck guys

In the dealer with oil change and the guy told me is 4 recalls in the 4wd. Is crazy when this going to end, the grinding noise when the car is in auto or 4wd is very bad. <br />
They have to come with the solution soon isn't right. <br />

Just saying driving on dry pavement in any kind of 4wd may not be the best and may have led to the failure. We get up to a foot of snow at a time here so I'm aware of snowy conditions. With that said I never drive 200 miles with 4wd in auto or anything else. I keep it in 2wd until the conditions ask for 4wd then I do what needs to be done but never for 200 miles.

Good thing you're under warranty I guess.

It doesn't hurt it at all to drive on dry pavement in 4auto. It's not like 4lock.
I left my wife's previous Tahoes in 4auto all winter long without issue.

Is that how 4wd High is suppose to operate?

Thought this problem was fixed for the 2015i vehicles

I have 2015i Denali, since the day 1 i had it in Auto mode, drove highway speeds, about 300 miles total on dry roads, another non highway 300 miles on wet or icy, and local driving 500miles total on snowy condition. Never got any warning nor problems.

After reading the thread did some donuts on parking lot on Auto and system ABS seems to be working more that other systems, won't let me do full donuts like my Dodge Charger. Threw it on 2WD steering on acceleration seems to be pretty slippery. I'm in Erie, PA so i don't want to take a chance - threw it back on Auto and will forget about it until its April, death tolls due to bad weather here was just about over 20 , so you got the idea of how bad it is here, and we don't consider its snowy and dangerous conditions until we get about 3 feet of snow and gets compacted into nice mini ice rinks by traffic lights due to cars dripping water from exhaust and mufflers etc

Some guys don't even drive the cars because they have lease and they short in miles some of the cars are parking all the time.
Some of them do not find out maybe after months of use. You will see. [emoji19]
My have the latest updates and auto or 4h is a grinding noise from the transfer case is very annoying but we have to live with this up to they fixed. [emoji19] [emoji368] [emoji361]
