I am new to the forum. We have a 2020 Bolt Premium. I noted some what I perceived as excess tire wear. I decided on a courtesy alignment check at Les Schwab Tires. I was surprised to find that camber was way off on booth from tires. Additionally, the alignment technician stated that camber was not adjustable.
The car has not been in a collision and we don’t recall any major pot hole hits.
We will take it to the dealer to check for bent parts. The caster and toe were within specification.
Has any run into a similar problem with wheel camber.
Thanks for any input.

What was the tire wear you noticed? What about tire rotation? Did you get a printout of the alignment specs?

Tire wear was on the inside edges.
Left from camber was -2.4 degrees and right was .9 degrees. Tires rotated at 7500, 15,050 and last week at 21,250. Bought a tread gage and I estimated that I would get about 30 thousand miles before they would get to about 3/32 in. I prefer replacing a little early.

It could be bad bushings somewhere.
You could get some camber bolts like these to get them back in alignment, but seems weird it would be that far out of spec.

Chevy Bolt Camber Bolts EZ CAM XR (14MM - PAIR) - spc81260

EZ Cam XRs are designed for non-slotted struts. They allow both positive and negative camber changes up to approximately 1.75° (depending on vehicle) by replacing the upper O.E. strut/spindle bolt. This easy to use adjuster provides built-in adjustment over the life of a vehicle just by rotating...

Thanks for the input. Will have the Chevy dealer check everything. However, without a collision or hitting a massive pothole; I don’t understand why both sides can be off. We will start by checking the alignment again to be sure. I read mixed reviews on camber adjusting bolts in terms of strength and will they slip. I know that modified car use them when suppension is changed so perhaps I’m overly cautious.Hopefully collision coverage will apply if something is bent.

I have used them in the past on some tracked cars. If torqued properly, I have never had them slip. As you said, you should definitely have the dealer check it out. It is possible there is some defects in the strut itself as well. To me that would be a warrantied item (assuming you are under the mileage).

Yes it is still within the warranty period. Hopefully the dealer will have another Bolt within specification to compare good measurements of components. Your mention of bad bushing is possible. There might have been a bad batch of bushings in the control arms. The spindle bolts appear to be splined. I not sure if the tab of the camber adjustment bolt washer would have a problem. If the hole in the strut is spined versus the female splines in the spindle. I’m learning more than I expected on what started as a simple alignment check.

They could possibly shift the subframe to bring things into spec considering one side is negative and the other is positive.
