2020 L5P Denali Steering Wheel Shake / Wobble

Hello all! I bought a 2020 Denali L5P a few weeks ago. I've put 350-400 miles on it and it drives like crap. At highway speeds (65-80) the steering wheel shakes back and forth/vibrates. The first time I took it back to the dealer they put 2 new tires on it and road force balanced all of them. Picked it up, but the ride was just as poor, if not worse. Brought it back to the dealer today and test drove 2 other new Denali L5Ps they had on the lot, and they drove just as bad and had the same steering wheel wobble.

The dealer just called after having it for a few hours and said "this is a known issue to GM and they don't currently have a solution". Has any other new 2020 owners experienced similar problems or have any solutions? I'm hoping its just the crappy stock Goodyear Wrangler trailrunner's that these trucks are coming with???

I test drove a 2020 Chevy LTZ about 10 miles a few weeks ago. It drove and rode great but I never looked to see what kind of tires it had.

Hope it works out for you because that is a really good looking truck. I think powerhaulic is right.

As I said in the PM, the Goodyear tires are the main source of the vibrations. The Goodyear Trailrunners are notorious for vibration/balancing problems across many other brands of vehicles that use them as OEM.

This issue has nothing to do with tires. There is a steering calibration coming to fix. Should be available in about two weeks for service.

With the strike going this fix will be available in two weeks? Is it just a engineering fix or a parts fix?

Just test drove one last week and it was an awesome drive/ride, couldn't get the grin off my face with the new ride & transmission making the new truck throttle response feel more like the 2006 lbz I had but with all the amenities of the new ride and quiet cab and features... Truly an enjoyable experience, now I'm trying to figure out if it is worth cashing in some investments and buying it outright rather than financing the difference between the 2017 3500 SRW Denali and the new one. No GM incentives yet and no low interest rates...........at least here in Canada.

I have about 3k on my 2020 now and I have noticed a small vibration. I took my rims and tires off my LML when I traded it in so I am taking it in on Friday to have them rotate and balance again plus do Fox shocks, Sulastic Shackles and a steering stabilizer to see if that corrects it for me. Again, mine was very mild and the ride overall has been great.
