Mercedes-Benz USA (MBUSA) is recalling 26,584 model year 2018-2019 C300s, C300 4MATICs, and C43 AMG 4MATICs.
The mounting bracket for the 12-volt battery may not be secured, allowing the battery to shift, possibly disconnecting the terminals in the event of a crash.
Loss of power from the battery can impair post-crash functions, such as communicating with emergency services and activating hazard lights. The battery may also detach and become a road hazard. Either can increase the risk of injury.
What to do
MBUSA will notify owners, and dealers will replace the battery mounting bracket free of charge.
The recall is expected to begin October 8, 2019.
Owners may contact MBUSA customer service at (800) 367-6372.
