2019-2026 Mercedes-Benz Recall 26V481: Door Lock Defect

Recall 26V481 covers 310,667 2019-2026 Mercedes-Benz vehicles for corroding driver-door lock micro-switches that can stop Auto-Park. Repair will be free once available.

What's wrong?

On affected 2019-2026 Mercedes-Benz vehicles, the driver's door lock contains a small microswitch that tells the vehicle when the driver's door is open. That signal helps shut down comfort functions after exit and helps trigger the electronic parking brake or Auto-Park feature when the vehicle expects the driver has left.

The problem is inside the microswitch housing. Because of a supplier development issue, moisture can enter the plastic housing under sustained heat, humidity, and condensation. When moisture reaches the electrical contacts, corrosion can keep the switch from reporting an open driver's door. If the vehicle does not see the door as open, the electronic parking brake or Auto-Park feature can fail to engage automatically, creating a rollaway risk under NHTSA campaign 26V481. The dealer repair is free.

Owners can notice comfort functions acting wrong after exit, such as the radio or lights staying on. That is the warning sign Mercedes-Benz identified before the parking-brake logic fails.

Who's affected?

Spans Mercedes-Benz A, C, CLA, CLE, GLA, GLB, and GLC lines from 2019-2026, all tied to the door lock microswitch.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.

What's the safety risk?

A vehicle rollaway increases the risk of a crash or injury. Before leaving the vehicle, confirm it is fully shut down and secure. If comfort functions, such as the radio, stay on after you exit, treat that as a warning sign and contact the dealer. Repair will be free at any franchised Mercedes-Benz dealer once available.

What should I do?

1. Check your VIN to confirm your 2019-2026 Mercedes-Benz model is included in this recall.
2. Watch for Mercedes-Benz's owner letter expected September 18, 2026, then contact a franchised Mercedes-Benz dealer for the free repair.
3. Ask the dealer to replace the driver's door lock, which fixes the corroded micro-switch that can stop Auto-Park from engaging.
4. Bring the recall notice if Mercedes-Benz has mailed one. If not, reference recall number 26V481 when you call.
5. Set the parking brake manually every time you park until the repair is complete.

What happens at the repair

The final dealer repair will be free once available. At the dealer, a Mercedes-Benz technician will replace the driver's door lock so the vehicle can detect whether the driver's door is open and apply the electronic parking brake or Auto-Park as designed. Parts and labor are covered under the recall. Mercedes-Benz used its standard reimbursement plan for this campaign. If you've already paid for a related door-lock repair, bring repair invoices or receipts to the service desk and ask how to submit documentation.
