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 (unsecured battery bracket) that can lead to injury by impairing post-crash safety functions or creating a road hazard, meeting the criteria for a Severe rating.
Plain-English summary
Mercedes-Benz USA, LLC. is recalling certain 2018-2019 C300, C300 4MATIC, and C43 AMG 4MATIC vehicles. The recall involves a defect where the mounting bracket for the 12-volt battery may not be secured. This issue allows the battery to shift, which could disconnect the terminals in the event of a crash.
The defect poses a safety risk because a loss of power from the battery can impair post-crash functions, such as communicating with emergency services and activating hazard lights. Additionally, the battery may detach and become a road hazard. Either of these scenarios can increase the risk of injury.
Mercedes-Benz will notify owners, and dealers will replace the battery mounting bracket free of charge. The recall began on October 18, 2019. Owners may contact MBUSA customer service at 1-800-367-6372 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
