Owner report 11728525 · 2026-04-01 (April 1, 2026)
My SUV pulls hard to the right when braking at speeds above 50 mph and much more on the interstates at 65 mph and above.

The vehicle has been to the service department numerous times....at first they suspected a braking issue and have had both calipers repl…

I was driving north on [XXX] when I felt a slight pull to the right. I figured it was my lane assist even though I was in my lane. Seconds later it felt like if someone was in my passenger seat and just yanked my steering wheel to the right hitting the guardrail. My whole tire and the assembly was off but everything was still intact to the tire. The tie rods, axle, ball joints, the whole assembly. During investigation I was told by the mechanic that the stabilizer bar was a clean break. There was damage to the front end and all down the side. I…
