My 2016 Colorado does not sit level when viewed from the rear. Took it back to dealer and they agreed. They contacted GM and they were told GM is aware of the problem and working on a fix. Does anyone have this issue? I love the truck but it looks odd. Does not seen to affect the handling. I am wondering what working on a fix means.

Good theory, thought about it, but it doesn't change with fuel level. 20 gals of diesel fuel only weighs 150 lb. unless the driver side of the motor is much heavier too because having the right rear high could mean the front left is low. My front left is my low corner and my right rear is my high corner. Kinda like when you load the back, the nose raises.

Ok not a full inch, found my measurement sheet

Before lift fender measurements:
RR 36.75"
LR 36.00"
LF 35.00"
LR 35.50"

3/4" higher RR 1/2" lower LF

After lift
RR 39.375"
LR 38.75"
LF 37.25"
RF 37.75"

Bout the same difference after lift

It did settle after some miles on the add a leafs, those are initial lift measurements before new tires

It seems that others have this issue also. I won't be adding a lift kit while under warranty. Did anyone else take theirs back to their dealer?

I've noticed that ours from the back, the drivers rear is lower and the passengers rear is higher. I haven't done anything about it yet though.

Just about the only thing you can do about it is to put a set of adjustable coil overs in the front.

I would not recommend putting a shim or anything under the leaf springs in the rear.

So did anyone ever come up with a solution to the tilt on the truck? Or is the adjustable coil covers on the front, it? I don't know if the tilt has gotten any worse, but I did notice it yesterday a little more, as where I was parked at was a split-level parking lot and I was standing below the truck looking up at it and you can definitely tell.

I saw a stock gasser today going down the road and it had the tilt BAD! Lol. It was that pretty blue color that I love.

Other than adjustable fronts, or spacers in the front to help offset, I can't think of another solution. I wouldn't want to shim the rear axle unevenly, but I wouldn't have a problem adjusting the difference out in the front suspension

I put a 1/2" spacer on the left front spring .(actually left the right side off, came as part of my leveling kit) Mine now measures exactly the came. I was nearly an inch low on the drivers side before.

Where at did you put it? I haven't done a leveling kit yet so I don't know where you would add a spacer at on the spring. Thanks.

I feel like a dumba*s, but I thought it was my driveway. But I have a fix! I decided to get a ZR2 diesel! Just hope it sits level or it will be the most expensive non-fix in my life!

After a 6000 ish miles road trip, my canyon level itself out. It squat a little bit now after carrying all the weight in the back, but perfectly level.
