Mercedes-Benz is recalling 4,969 2019 vehicles because seat belt pre-tensioners may not activate in a crash, increasing injury risk.
What this means for you
Our assessment, not the agency’s: severity 4/5 (Severe).
The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.
Our severity reasoning: The recall involves a structural vehicle defect where safety restraints may fail to deploy, which aligns with the rubric criterion for 'structural vehicle defect' or 'significant injury' risk.
Plain-English summary
Mercedes-Benz USA, LLC is recalling certain 2019 model year vehicles, including the C300, C43 AMG, E450, E53 AMG, S450, S560, S63 AMG, S65 AMG, and Mercedes-Maybach S560 4Matic and S650. The recall covers a total of 4,969 vehicles.
The defect involves the seat belt system, where a correctly fastened seatbelt may be inaccurately detected as being unfastened. This error prevents the seat belt pre-tensioners from activating in the event of a crash. If the tensioning does not activate, it can increase the risk of injury to occupants.
Mercedes-Benz will notify owners, and dealers will replace the seat belt buckles free of charge. The recall began on March 18, 2019. Owners may contact MBUSA customer service at 1-800-367-6372 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
