2021 Mercedes-Benz GLB250 and AMG GLB35 airbag mounting defect
Mercedes-Benz is recalling certain 2021 GLB250 and AMG GLB35 vehicles because the driver-side window airbag may not be properly mounted to the A-pillar, which could prevent proper deployment during a crash.
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: This recall involves a concrete safety defect—improper mounting of a critical safety component (driver-side window airbag) that could prevent proper deployment during a crash. The rubric criterion 'risk-of-harm products where injury has not yet been reported' applies, as no crashes, injuries, or deaths are documented in the source text.
Plain-English summary
Mercedes-Benz USA, LLC is recalling certain 2021 GLB250 and AMG GLB35 vehicles. The driver-side window airbag may not have been mounted correctly to the lower area of the A-pillar. These vehicles fail to comply with Federal Motor Vehicle Safety Standard 226, which governs airbag ejection mitigation.
As a result, the driver-side window airbag may not function properly during a crash, increasing the risk of injury to the driver.
Dealers will inspect the mounting of the driver-side window airbag and repair it as necessary at no cost to owners. Owner notification letters were mailed in December 2021. Owners may contact Mercedes-Benz USA customer service at 1-800-367-6372 or the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153).
