Although correctly fastened, the front seat belts may be inaccurately detected as being unfastened, which may cause the electric PRE-SAFE-function and the pretensioner to be deactivated.
Thus, these devices may not deploy during a crash, increasing the risk of injury.
What to do
MBUSA will notify owners, and dealers will inspect the front seat belt buckles, replacing them as necessary free of charge.
The recall is expected to begin December 31, 2019.
Owners may contact MBUSA customer service at (800) 367-6372.
