What's wrong?
The fuel feed line on the 2014 Mercedes-Benz E350 carries gasoline from the fuel system toward the engine. At the hose connection, the end of the metal line is supposed to have a double flare, a shaped lip that helps the hose connection stay tight and sealed under fuel pressure.
On the affected cars, a manufacturing process at the fuel-line plant left the line with a single flare instead of the specified double flare. That smaller connection shape does not secure the hose and line the way the design requires. The joint can loosen or leak at the fuel feed line connection, especially once the system is under normal operating pressure.
The warning sign listed for owners is fuel odor. If you smell gasoline around the vehicle, treat that as the warning sign for this defect and have the fuel line connection inspected under recall 15V792.

What's the safety risk?
A wrong fuel feed line fitting can let fuel leak or allow the line to disconnect. Fuel near an ignition source increases fire risk, and a disconnected line can stall the vehicle and increase crash risk. Fuel odor is the warning sign. If you smell fuel, stop driving and call the dealer. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2014 Mercedes-Benz E350 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free correct fuel-line installation, which fixes the incorrect flare fitting that can leak fuel or disconnect.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 15V792 when you call.
- Avoid driving with a fuel smell, visible fuel leak, or stalling before the repair. Ask the Mercedes-Benz dealer for guidance before moving the vehicle.
What happens at the repair
At the dealer, a Mercedes-Benz technician installs the correct fuel feed line, replacing the line built with the wrong flare fitting. The recall repair is free, with parts and labor covered. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain under warranty. Ask the service desk how that warranty coverage applies if you have prior repair paperwork.
