Latches/locks/linkages: doors, lock

NHTSA campaign 26V481000 · reported July 24, 2026 · Mercedes-Benz USA, LLC · 310,667 vehicles potentially affected

The problem

The fix
Dealers will replace the driver's door lock, free of charge. Owner notification letters are expected to be mailed September 18, 2026. This will be a phased campaign, with the remedy becoming available in different phases based on model and model years. Owners may contact MBUSA customer service at 1-800-367-6372.
