Owner complaint summary

During snowfall, the front camera becomes obstructed, leading to a malfunction in the smart brake system. When this occurs, an alert appears indicating a “Smart Brake Failure,” accompanied by an audible warning and the illumination of the check engine light. The vehicle then exhibits unpredictable behavior, including unintended braking and sudden acceleration, creating a hazardous driving situation. The only temporary resolution is to restart the vehicle; however, the check engine light remains on for several days before eventually turning off. This issue occurred while I was driving on the highway on February 19, 2025, posing a significant safety risk. This is not the first time the car has done this.

This is an owner complaint filed with NHTSA (ODI #11643730). It is not automatically an official recall, investigation outcome, or manufacturer admission unless the complaint text itself describes one.
