The side crash sensor connectors may come loose, which could delay the activation of airbags and seat belts in a side impact crash.
Airbags and seat belts that don't function as intended can increase the risk of injury during a crash.
What to do
Dealers will inspect and replace -- as necessary -- the side impact crash sensors free of charge.
Owner notification letters are expected to be mailed September 10, 2021.
Owners may contact MBUSA customer service at (800) 367-6372.
