On [XXX], at approximately [XXX], I was driving my 2026 Volvo XC90 (VIN: [XXX], mileage: 12,393) westbound on [XXX], at approximately 50 mph. While travelling on a straight road, with vehicles passing in the adjacent left lane and no apparent hazard ahead, my vehicle suddenly initiated extremely aggressive automatic emergency braking. A collision warning and audible alert occurred almost simultaneously with the braking. The deceleration was so severe that my seatbelt locked, throwing me forward against the restraint and causing physical pain. The brakes then released, and the vehicle continued normally. I was driving manually, without adaptive cruise control or Pilot Assist engaged. This appears to be a false activation of the automatic emergency braking system. The unexpected braking created a serious risk of a rear-end collision. I have reported this incident to Volvo and requested a full investigation. I am asking NHTSA to investigate this potentially dangerous safety defect, including possible sensor, radar, camera or software malfunctions.
