Mercedes-Benz Recalls Vehicles for Radar Sensor Software Error

Mercedes-Benz is recalling 2019-2020 vehicles because a software error in the radar sensor may impair Active Brake Assist, increasing crash risk.

What this means for you

Our assessment, not the agency’s: severity 3/5 (High).

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: The recall involves a safety system impairment that increases the risk of a crash, but the source text does not report any specific injuries, fatalities, or agency classification of 'death/serious injury reported.'
