What's wrong?
The diesel fuel pump on the 2019 Mercedes-Benz Sprinter 1500, Sprinter 2500, Sprinter 3500, and Sprinter 4500 sits at the fuel tank and helps move fuel from the tank into the diesel fuel system. A bayonet lock holds the pump against the tank, much like a twist-lock cap. When that lock is fully closed, the tank and pump seal together during driving and refueling.
On affected Sprinter vans, that bayonet lock was not fully closed and locked during manufacturing reassembly. A loose lock leaves the seal between the fuel pump and fuel tank incomplete. Diesel fuel can leak from that joint, and during refueling the station pump can keep flowing after the tank is full, which can cause diesel fuel to overflow.
If this problem is present, you can see fuel droplets on the ground near the van or smell diesel fuel around it. Those signs mean fuel has escaped from the tank area.

What's the safety risk?
Diesel fuel leaking from the vehicle can make the road slippery and increase the risk of a crash. If you see fuel droplets on the ground or smell diesel near the vehicle, avoid driving it and call the dealer. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2019 Mercedes-Benz Sprinter 1500, Sprinter 2500, Sprinter 3500, or Sprinter 4500 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free fuel-pump bayonet-lock inspection and locking repair that fixes the fuel-pump-to-tank leak path.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 19V798 when you call.
- Avoid topping off the diesel tank until the repair is complete, and stop driving if you smell fuel or see a fuel leak.
What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the bayonet lock between the fuel pump and fuel tank, then locks it if needed. The recall repair is free, with parts and labor covered. Out-of-pocket repairs already paid are handled through the existing new vehicle warranty, not through a separate reimbursement program, because all involved vehicles remain under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.

Frequently asked questions
What is recall 19V798?
Recall 19V798 covers 4,987 2019 Mercedes-Benz Sprinter 1500, 2500, 3500, and 4500 vehicles with diesel fuel systems. The bayonet lock between the fuel pump and fuel tank was not locked during manufacturing, so diesel fuel can leak or overflow during refueling.
What should I do if my 2019 Mercedes-Benz Sprinter is on this recall?
Check your VIN to confirm your specific van is included in recall 19V798. If it is, contact a franchised Mercedes-Benz dealer to schedule the fuel pump bayonet lock inspection. The dealer will lock it as needed, and the recall repair is free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. For recall 19V798, Mercedes-Benz dealers will inspect the bayonet lock on the fuel pump and lock it as needed free of charge.
What is the safety risk in recall 19V798?
NHTSA campaign 19V798 says a diesel fuel leak can create slippery road conditions and increase crash risk. The same defect also affects refueling, since the station fuel pump can fail to stop automatically once the tank fill level is reached, causing fuel overflow.
What if I bought the Sprinter used?
The free recall repair still applies. Recall eligibility follows the VIN, not the first owner. Check your VIN to confirm whether your 2019 Mercedes-Benz Sprinter is included, then reference recall 19V798 or Mercedes-Benz recall number VS3KRAFMOD when you call the dealer.
