Followup to earlier issue of wheel squeaking. Again, could not fix it, but this time, the noise did not come back, or so I think. Could actually be the warm summer weather. Car suspension was uneven and car started tracking to the left. Dealership acknowledged the issue and fixed the suspension height and made sure the steering wheel stayed true and center.
