Mercedes-Benz C 300 Recall 18V839: Seat Belt May Not Tighten in a Crash, Raising Injury Risk

NHTSA campaign 18V839, reported November 27, 2018, 4,969 vehicles potentially affected.

What this recall means for you

Certain 2019 Mercedes-Benz vehicles may have a seat belt buckle that can incorrectly detect a properly fastened belt as unfastened. When this happens, the seat belt pre-tensioners may not activate in a crash.

If the pre-tensioners do not activate during a collision, the seat belt may not tighten as intended, which can increase the risk of injury to occupants.

Mercedes-Benz USA will notify owners, and authorized dealers will replace the seat belt buckles free of charge. Owners can contact Mercedes-Benz USA customer service at 1-800-367-6372, referencing recall number 2019020012. You can also check your vehicle's VIN for open recalls.
