Owner complaint summary

This problem first occurred on a state highway in [XXX] in 2023 and again in 2026 (this incident.) While driving south on XXX, there was an undulation/slight bump in the interstate while in a mild right hand curve. My vehicles brakes engaged without my input and slowed me down from 70mph to 35mph with traffic behind me. My gas accelerator and brake pedal were unresponsive from user input. At no point was my vehicle out of control to trigger such aggressive braking from my ESC, ERM, or ABS. The concern here is that thankfully this was on dry roads and traffic was far enough behind me to avoid a collision. My concern is this happening in winter weather/icy/wet roads, or with significant traffic behind me causing a possible high speed rear-end vehicle accident. There was a safety recall for ESC/ABS a few years ago on my vehicle that I dealt with through the dealer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
