What's wrong?
The diesel fuel tank on the 2017-2018 Roadtrek E-Trek and RS Adventurous stores fuel for the engine and should remain sealed during filling, parking, and driving. On motorhomes with the driver's-side second row captain seat option, the seat pedestal is mounted through the floor above the frame area near the tank. Those mounting holes are supposed to stop before reaching the tank.
On affected motorhomes, an assembly operator drilled deeper than the work instructions allowed while installing that seat pedestal. The drill passed through the lower side of the frame member and into the OEM Mercedes diesel fuel tank on some units. A punctured tank cannot hold fuel as designed, so fuel can leak during or after filling and the tank must be replaced.
Owners can notice the problem at the fuel pump. The warning signs are a strong diesel odor during filling and diesel spilling onto the ground below the vehicle after the tank is filled.

What's the safety risk?
A damaged fuel tank can leak diesel fuel and increase the risk of a fire. Watch for a strong diesel odor during fuel fill or fuel spilled on the ground after filling. If either sign appears, stop using the vehicle and call the dealer before refueling again. Repair is free at any franchised Roadtrek dealer.
What should I do?
- Check your VIN to confirm your 2017-2018 Roadtrek E-Trek or RS Adventurous is included in this recall.
- Contact a franchised Roadtrek dealer to schedule the free diesel-fuel-tank inspection and replacement when required.
- Bring the recall notice if Roadtrek mailed one. If not, reference recall number 18V528 when you call.
- Ask the dealer to inspect for fuel-tank damage from the second-row seat pedestal installation, since a damaged tank can leak fuel.
- Avoid parking near heat sources or open flame until the fuel-tank inspection and repair are complete.
What happens at the repair
At the dealer, a Roadtrek technician inspects the diesel fuel tank for damage from the driver's side second row seat pedestal installation. If the tank is damaged, the technician replaces it. The inspection and any needed tank replacement are free under the recall. Roadtrek has a general reimbursement plan on file for owners who already paid for a related diesel fuel tank repair before the recall notice. Bring repair paperwork and payment records to the service desk, or contact Roadtrek customer service for the reimbursement process.
