Owner report 11749901 · 2026-07-13 (July 13, 2026)

Owner report 11742258 · 2026-06-05 (June 5, 2026)
My auto assist emergency braking function has triggered 3 times over the last few months with no other cars or hazzards near me. There was not warning. Each time it caused sudden unexpected severe jerking. More importantly, had there been a car behind me, it would have run into me and caused an collision. I reported this to the dealer who was unable to replicate the problem so it returned my car without a solution. I have notified MBUSA.
