What's wrong?
The CCP1 port on the 2020 Wonder W24MB, W24RTB, and W24FTB is an electrical connection located on the driver's seat base of the Ford Transit chassis. It is part of the interior wiring system and has to stay clamped tightly so current flows through the intended connection instead of through loose contact points.
On affected Wonder motorhomes, the CCP1 wire connection was not tightened to the required 35 in-lb torque value during manufacturing. The build instructions did not list that torque requirement for the 2020 Ford Transit chassis, so the installer left the connection finger tight. A loose electrical connection can lose solid contact and short circuit.
The warning sign is physical, not a driving symptom: the nut on the CCP1 connection is finger loose instead of properly torqued. A dealer or service technician checking the driver's seat base would find the loose connection before it is corrected.
Who's affected?
Covers three Wonder W24 configurations from the 2020 model year, all tied to the same CCP1 port wiring.

What's the safety risk?
NHTSA campaign 20V370 says a short circuit at the CCP1 electrical connection increases the risk of a fire. The issue is a loose connection nut, so schedule the dealer repair soon and have the connection tightened to specification. Repair is free at any franchised Wonder dealer.
What should I do?
- Check your VIN to confirm your 2020 Wonder W24MB, W24RTB, or W24FTB motorhome is included in this recall.
- Contact a franchised Wonder dealer to schedule the free CCP1 electrical-connection tightening that corrects the loose seat-base connection and fire risk.
- Bring the recall notice if Triple E mailed one. If not, reference recall number 20V370 when you call.
- Drive cautiously until the repair is complete, and stop using the motorhome if you notice signs of an electrical short.
What happens at the repair
At the dealer or an RV service center, a Wonder technician tightens the CCP1 electrical connection on the driver's seat base to the required 35 inch-pounds specification. The recall repair is available, and parts and labor are free. Triple E also sent owners a standard procedure for the same torque repair, but the dealer or service center path keeps the work documented. If you paid for this repair before the recall notice, Triple E says the retail owner or servicing center will be reimbursed for repair costs. Bring the repair invoice and any related paperwork when you arrange service.
