Picked up truck today. All shocks were replaced and it drives substantially better - not near as stiff. Technician said this is likely only a band aid - that they will stiffen up over time and it will likely go back to the way it was. Yet again I was told "this is what you get when you get a vehicle with MRC". That is really NOT what I want to continue to hear! Number one, it is a standard feature on a Denali XL so it's not like I had an option and number two there is no disclaimer whatsoever anywhere about the implications of having a vehicle with MRC (VERY stiff ride)! Had I known, I would have never bought this truck. And again, GMC could have easily remedied this with a couple of electronic suspension settings rather than it being only a default. Enough ranting from me...we'll see what happens. I will update everyone periodically.


My SWB denali has MRC and I hate it. Ride blows. Its the only reason I ordered 20" wheels for it instead of the standard 22's.

But I gotta ask...Didnt you realize how ****** the ride was when you test drove it? I did but I was willing to suffer through it because for me the pros outweighed the few cons...

It drove great for first several thousand miles - estimated 6K. Tech said that is not uncommon - that suspension stiffens up over time. Each truck is different regarding how long it takes. So no, had it driven like this from day one I would have never bought it.

Interesting. I agree with you, I wish they had added adjustments to it like with the esky

What are you implying? That there is a fix for this, service department just hasn't found it yet? Maybe old shocks were damaged and these new ones won't stiffen like originals did?

All I'll say is you think you have problems now.... wait till it hits 40k your just at the tip of the iceburg. When ours hit about 45k miles it started having a sharp vibration that would carry through the truck way after you hit a bump. The dealer took care of that when they replaced the transmission at 50,000 miles. The truck has been going south since the 40k mark and talking to other people they have similar experinaces. I almost wonder if the Denali package was a mistake it seems as though these are the WORST of the crop. I can't even remember all the problems this truck has had because it has has too many. I apologize for all the negative attitude.

Your 2011 Avalanche doesn't have MRC. And what you said about your Escalade doesn't make any sense.

I've seen it in other threads. If a tow or transportation company winches the vehicle down too tight it'll damage the sensors in the shock that put it in stiff mode. The vehicle will stay in that mode leading to poor ride quality.

Look it up. There are several threads out there in the internet.

Doesn't happen to me but it seems practical enough.
