What's wrong?
The rear junction box on the 2021-2022 Prevost X3-45 Commuter is an electrical connection point near the back of the coach bus. It holds heavy battery and starter harness cables, which carry high current between the charging, starting, and power distribution parts of the bus. The cable has to stay clamped tightly so current flows through the connection instead of heating it.
On affected buses, a nut on the rear junction box was not tightened correctly during assembly. Because the nut is loose, the cable can move and lose solid contact with the terminal. That poor contact adds electrical resistance, and resistance turns current into heat at the junction box. The issue is an installation problem, not a bad harness by itself.
There is no warning sign before the junction box overheats. The bus can look and run normally until the loose connection heats up.
Who's affected?
The scope spans 2 model years for the same commuter bus model, with electrical system harness parts identified for each year.

What should I do?
- Check your VIN to confirm your 2021-2022 Prevost X3-45 Commuter is included in this recall.
- Contact a franchised Prevost dealer to schedule the free rear junction box cable tightening that secures the loose cable and reduces the fire risk.
- Bring any Prevost owner letter to the appointment, or reference recall number 22V179 when you call.
- Keep the coach out of service and call Prevost if the rear junction box shows heat, smoke, or a burning smell before the repair.
What happens at the repair
At the dealer, a Prevost technician properly tightens the cables on the rear junction box and checks the related nut so the cable connection stays secure. Parts and labor are covered under the recall, so the repair is free. Prevost has a general reimbursement plan on file for owners who already paid for the same rear junction box cable repair before the recall work. Contact Prevost customer service or ask the dealer how to submit documentation for review.
