2012-2020 Mercedes-Benz ML/GLE Recall 22V955: Fuel Pump

Recall 22V955 affects 348,183 2012-2020 Mercedes-Benz ML and GLE SUVs for water-damaged fuel pump control units. Repair is free at any franchised Mercedes-Benz dealer.

What's wrong?

The fuel pump control unit in these 2012-2020 Mercedes-Benz ML and GLE SUVs sits in the spare tire wheel well area. It manages electrical power and commands for the fuel pump, which sends fuel from the tank to the engine. When the unit works normally, the engine keeps receiving the fuel supply it needs while the vehicle is moving.

On affected vehicles, water can collect in the spare tire wheel well. Rear-area sealing does not meet specification, and water intrusion can come from different paths in that area. Once water reaches the fuel pump control unit, it can damage the electronics and interrupt fuel pump operation. That can cause the engine to stall while driving.

Owners can notice a damp carpet in the rear of the vehicle or hear water sloshing in the spare tire wheel well. A check engine light or another instrument cluster warning can also appear when the condition is present.

Who's affected?

Spans ML and GLE variants across the 2012-2020 model years, all tied to the fuel pump control module.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific SUV is included.

What's the safety risk?

Water intrusion can lead to an engine stall while driving, which increases the risk of a crash. Watch for damp rear carpet, water sloshing in the spare tire wheel well, a check engine light, or an instrument-cluster warning. Schedule the repair soon and use extra caution until it is complete. Repair is free at any franchised Mercedes-Benz dealer.

What should I do?

1. Check your VIN to confirm your 2012-2020 Mercedes-Benz ML550, ML350, ML250, AMG ML63, GLE450, AMG GLE63, GLE350, GLE400, AMG GLE43, GLE300D, GLE550E, Gle 550 E, Gle 350, Gle 400, or ML400 is included in this recall.
2. Contact a franchised Mercedes-Benz dealer to schedule the free water-drain-plug inspection and fuel-pump-control-unit repair that protects the unit from water in the spare tire well.
3. Bring the owner letter if Mercedes-Benz mailed one. If not, reference recall number 22V955 when you call.
4. Drive cautiously until the repair is complete, since an engine stall while driving raises crash risk.

What happens at the repair

At the dealer, a Mercedes-Benz technician installs a water drain plug, checks the spare tire wheel well for water intrusion, and replaces the fuel pump control unit if inspection shows damage. The recall repair is free, including parts and labor. Mercedes-Benz is providing reimbursement information to owners because some vehicles were previously subject to this condition before the recall notice. If you already paid for a related water intrusion or fuel pump control unit repair, keep your documentation and ask the service desk or MBUSA customer service how to submit it.
