What's wrong?
The right front fender liner on these 2021 Mercedes-Benz Sprinter 1500, Sprinter 2500, Sprinter 3500, and Sprinter 4500 vans is the plastic shield inside the wheel opening. It keeps road spray and debris away from nearby parts. The front brake hose is a flexible line that carries brake fluid to the front brakes when you press the pedal.
On affected vans, the fender liner and body shell do not leave enough clearance around the brake hose. The liner can touch the hose as the van moves and the front suspension works. That contact can rub the hose, chafe through its outer surface, and damage the line that holds brake fluid pressure.
Before failure, the driver can notice longer brake pedal travel and a soft brake pedal. The instrument cluster can also show a red low brake fluid warning message.
Who's affected?
The same right fender liner is involved across Mercedes-Benz and Freightliner Sprinter van classes, with both hydraulic brake hose and body structure listed for the affected vans.

What's the safety risk?
A damaged brake hose can leak brake fluid, lengthen stopping distance, and increase crash risk. Watch for longer brake pedal travel, a soft pedal, or a red low-brake-fluid warning message. If these signs appear, stop driving and call a Mercedes-Benz dealer for guidance. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2021 Mercedes-Benz or Freightliner Sprinter 1500, Sprinter 2500, Sprinter 3500, or Sprinter 4500 is included in this recall.
- Contact your nearest franchised Mercedes-Benz dealer to schedule the free repair.
- Schedule the front fender liner and brake hose inspection, fender liner trim modification, and brake hose replacement if the liner has contacted or damaged the hose.
- Bring the recall notice if Mercedes-Benz has mailed one. If not, reference recall number 21V933 when you call.
- Drive cautiously until the repair is complete. Leave extra stopping distance and avoid hard braking.
What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the front brake hose condition and its clearance from the front axle fender liner. The technician modifies the fender liner trim and replaces the brake hose when inspection shows damage or inadequate clearance. Parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, since all involved vehicles remain covered by that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.

Frequently asked questions
What is recall 21V933?
Recall 21V933 covers 98 2021 Sprinter 1500, Sprinter 2500, Sprinter 3500, and Sprinter 4500 vehicles with front axle fender liner clearance that can let the liner contact and damage a brake hose. A damaged hose can leak brake fluid and extend stopping distance.
What should I do if my 2021 Mercedes-Benz Sprinter is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 21V933. If it is, contact a franchised Mercedes-Benz dealer to schedule the inspection, fender liner trim modification, and brake hose replacement if needed. Reference recall number 21V933 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. Mercedes-Benz dealers will inspect the brake hose clearance, modify the fender liner trim, and replace the brake hose if needed free of charge.
What is the safety risk?
The safety risk is longer stopping distance from a damaged brake hose. If the fender liner contacts the hose, the hose can leak brake fluid, which can make the vehicle need more distance to stop and increase crash risk.
