Owner complaint summary

The Automatic Emergency Braking (AEB) system activates unexpectedly and dangerously. Incident 1 5/7/2026: While driving approximately 2 mph in a drive-thru and rounding a curve, the vehicle suddenly applied full braking without warning. The braking force was severe enough that I struck my face on the steering wheel and my child was thrown forward in a secured car seat. Incident 2 5/19/2026: While merging onto a busy road behind a semi truck, the vehicle again applied sudden hard braking after I safely merged. This caused the vehicle behind me to nearly rear-end me, creating a high-risk traffic situation. These events occurred with no obstacle or reason that would justify emergency braking. In addition, the vehicle developed a coolant leak around 20,000 miles, raising concerns about overall reliability and potential related system issues. The unexpected braking presents a serious safety hazard and increases the risk of rear-end collisions and injury. The vehicle is being brought to a dealer for inspection, but the issue is intermittent and may not be easily reproduced.
