Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My 2027 Rivian R2 experienced uncontrolled acceleration to approximately 95 mph in a 55 mph zone. The incident lasted approximately 50 seconds, with uncontrolled power output despite simultaneous hard braking. I pressed the brake pedal as hard as I could. Burning fumes developed while I tried to regain control. We have in-cabin video with audio. I provided Rivian more than 40 seconds of footage showing power-output and braking indications during my braking attempts. Near the end, I deliberately moved the drive stalk vertically upward, unlike my previous horizontal movements. …”

NHTSA complaint #11768472, filed 2026-10

“Uncontrolled acceleration for approximately 50-seconds. In-cabin video shows the immediate moment of power disengagement after an upward stalk motion occurs (that controls the vehicle's drive modes). Rivian's report omitted this, despite being sent the trimmed 1-second clip (should be watched in slow-motion and/or frame-by-frame to view the HUD and action). Speeds reached over 90-mph. HUD clearly shows simultaneous braking and power output. …”
