Silverado and Sierra Vibration Problems, 2013 and 2014.

Model: Silverado & Sierra

Problems: Vibration

Model Year: 2013 & 2014

Summary: I know this is going to look suspicious being only my third post but I wasn’t sure what forum to join at first. I have noticed a shake or vibration in my new 4×4 crew 5.5 box 5.3 truck it seems to come and go and has been a pain to pin point what makes it happen. I can feel it in the steering wheel, seat and sometimes the gas petal but mostly in the steering wheel. It seems to be most noticeable going up or down hill with very light acceleration but can do it on level ground at cruise speed too. And the fun part is it doesn’t always do it to make it more of a challenge to diagnose it.

Brought it to the dealer last week and I thought the mechanic was going to think I was crazy but he did feel it too which was a relief also the service writer test drove it after they balanced and rotated the tires and he said its slight, but he felt it too. We scheduled it to come in tomorrow and are opening a warranty claim. I have very little faith that its going to get fixed because of the nature of the vibration and it being so new that there probably isn’t any info out there on what it could be. I really don’t know what they can do tomorrow other then make phone calls. If I had to venture a guess I’m going to say its in the transmission or possibly the engine.

We also have a 2012 equinox and on the same roads there’s no vibration at all.

Also I have the z71 and man does that thing ride STIFF! Every repair strip in the tar is felt hard! Anyone know if it just takes some miles to get the shocks broke in (2600 on it now)? My 04 was a z71 too and rode much, much softer then this.
