The problem
Mercedes Benz USA LLC (MBUSA) is recalling certain 2017-2018 GLC43 AMG, 2016-2018 GLC300 4Matic, 2016-2018 GLC300, 2018 GLC63 AMG 4Matic, and 2018 GLC350e 4Matic vehicles. The seat belt latch plates (the parts that insert into the buckles) for the outboard rear seats may retract into the interior paneling, preventing the occupants from being able to use the seat belts.
The risk
If the rear seat passengers cannot fasten their seat belts, they have an increased risk of injury in the event of a crash.
The fix
MBUSA will notify owners, and dealers will install a buffer to the c-pillar paneling, free of charge. The recall is expected to begin May 14, 2018. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2018030012.
