Mercedes Door-Lock Recall Covers 310,667 U.S. Vehicles
Mercedes-Benz is recalling 310,667 vehicles in the United States because moisture may affect a microswitch in the driver-door lock, according to a July 31 Kelley Blue Book report. If the vehicle does not correctly recognize that the driver door has opened, automatic parking functions may not operate as expected. Owners should check the specific vehicle identification number rather than relying only on model year.
The recall covers 29 Mercedes-Benz vehicle lines from model years 2019 through 2026, according to the report. A broad year range does not mean every vehicle in those lines is included. Production dates and component records determine the affected population, which is why a VIN search or an official recall notice is more reliable than a general model list.
The issue involves the housing around a driver-door lock microswitch. Moisture can enter, leading to corrosion and an incorrect door-status signal. In certain circumstances, the electronic parking brake or an automatic Park function may not engage when the driver exits. If the vehicle is not otherwise secured, unintended movement could occur.
Possible clues include comfort features behaving differently after the driver exits, such as the radio or lights remaining on. Those signs are not a diagnosis, and a vehicle can be included without displaying an obvious symptom. The report says Mercedes-Benz had identified 176 field cases involving comfort-function concerns and no U.S. rollaway reports at the time of filing.
The NHTSA campaign record for 26V481 is the federal reference for the recall. Mercedes-Benz plans to replace the driver-door lock on affected vehicles. Recall repairs are performed without charge to the owner, but parts scheduling and notification timing can vary, so owners should contact an authorized service location after confirming VIN eligibility.
What Mercedes-Benz Owners Should Do
Check the VIN through the Mercedes-Benz recall lookup or NHTSA. VIN records may take time to update around the filing date, so repeat the check after receiving a manufacturer letter or if the campaign initially does not appear. Keep the recall notice with the vehicle records until the repair is documented as complete.
Until the vehicle is inspected, use deliberate parking habits. Stop fully, select Park, apply the parking brake manually and confirm the vehicle is secure before releasing the brake pedal or exiting. On a slope, use the parking brake and orient the wheels as recommended in the owner’s manual. Never rely on an automatic convenience feature when the vehicle’s status is uncertain.
If a warning appears or the vehicle behaves unexpectedly, stop in a safe location and consult roadside assistance or a qualified service professional. Owners should not disassemble the lock or attempt an improvised electrical repair. The recall remedy is designed around the identified component and should be recorded under the VIN.
The NHTSA SaferCar app can send recall alerts after a user enters a VIN or scans a vehicle barcode. It is useful for households with multiple vehicles, but owners should still keep contact information current with the manufacturer and respond to mailed notices.
Recall status should also be checked during a used-car purchase. Shoppers can review the used-vehicle selection and ask for VIN-specific recall documentation before completing a transaction. An open recall is not the same as a condition diagnosis, but the repair status belongs in the ownership plan.
Current owners can organize follow-up through the service and ownership-cost resources. Anyone considering a different vehicle can also obtain a trade-in estimate; recall status should be disclosed accurately and should not be confused with an unsupported claim about the vehicle’s overall condition.
The owner-focused response is simple: verify the VIN, apply the parking brake manually, schedule the no-cost remedy if included and retain the repair record. There is no need for alarm, but automatic parking behavior should be taken seriously. More recall explainers are available through the automotive news resources.
