Mercedes-Benz Cabriolet rear headrests may be mounted incorrectly

NHTSA campaign 21V406000 · Reported 2021-05-28 · Mercedes-Benz USA, LLC

medium How serious is it? About this label

Incorrectly mounted headrests could move or detach from the seat during a crash, increasing the risk of injury. The notice does not tell owners to stop driving.

What's wrong, in plain English

The rear headrests in these convertibles may not have been attached to the seatbacks correctly at the factory. The guide bushings that hold a headrest in place can be wrong or poorly assembled, so a headrest could shift out of position or come off the seat during a crash, which is exactly when a back-seat passenger needs it most. A dealer will inspect the rear seatback guide bushings and replace them if necessary, at no cost to you.
