Transport CanadaHigh Risk
Defect
On one vehicle, the front passenger seat belt buckle may become blocked after the automatic locking retractor (ALR) is used. As a result, the front passenger may not be able to use the seat belt.
Safety Risk
Not wearing your seat belt can increase the risk of injury in a crash.
Remedy
In the interim, if this problem happens, to reduce the safety risk, Mercedes-Benz advises that you can move the front passenger seat to the rearmost position to unblock the seat belt buckle until the recall repairs are completed. Mercedes-Benz will notify the owner by mail and advise them to take their vehicle to a dealership to replace the front passenger seat belt.
