A correctly fastened seatbelt may be inaccurately detected as being unfastened, preventing the seatbelt pre-tensioners from activating in the event of a crash.
If the seat belt tensioning does not activate in the event of a crash, the risk of injury can increase.
What to do
MBUSA will notify owners, and dealers will replace the seat belt buckles, free of charge.
An interim letter will be mailed beginning January 25, 2019, to notify owners of the issue. A second letter will be mailed once remedy parts are available.
Owners may contact MBUSA customer service at 1-800-367-6372.
