When my car was in reverse motion, I stepped on the brake pedal, but the car did not stop. I stepped on the brake pedal numerous times, but the brake did not function. My car backed into the front of the car in line behind me damaging both vehicles. The automatic emergency braking system did not activate, and there was no rear collision warning sound or message. …”
NHTSA complaint #11684842, filed 2025-09“Hit a deer that impacted the passenger side of the vehicle.

The passenger airbag did not deploy, nor did emergency braking or collision avoidance warning go off as deer was crossing from the left (driver) side to passenger side where it impacted. No injuries, but car had to be towed due to front damage. Lexus has no fix for the airbag sensor recall for almost a year now.”
