Recall 23V879 affects 26 2023-2024 Fccc MT50E and Saf-T-Liner C2 Jouley electric buses for loose inverter-cable fasteners. Repair is free at any franchised Fccc dealer.
Fccc is recalling 26 2023-2024 MT50E and Saf-T-Liner C2 Jouley electric buses because the high-voltage inverter cable has a securement problem that can cause loss of drive power. That loss of power increases crash risk, and the Fccc dealer repair will be free once the remedy is available.

What's wrong?
The high voltage junction box on the 2023-2024 Fccc MT50E and Saf-T-Liner C2 Jouley electric buses is the power distribution unit for the propulsion system. It routes high voltage battery power through the inverter cable, and the inverter turns that power into the electrical output the drive system uses to move the bus.
In affected buses, the fasteners at the joint between the high voltage inverter cable and related hardware were not tightened to the required torque. Torque is the measured tightening force that keeps an electrical joint clamped. If that joint is loose, the cable connection can lose proper contact, and the bus can lose drive power.
There is no warning sign before failure. The recall filing reports no warning or detectability, so an owner or operator should not expect a light, sound, or change in driving feel before the connection problem shows up.
Who's affected?
Covers the MT50E and Saf-T-Liner C2 Jouley across the 2023 and 2024 model years, both tied to the same electric propulsion system component.
| 2024 Fccc MT50E | electric propulsion system |

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
There is no warning sign before the vehicle loses drive power. If propulsion drops out, steer out of traffic when safe and call a franchised Fccc dealer. A loss of drive power can increase the risk of a crash. Repair will be free at any franchised Fccc dealer once available.
What should I do?
- Check your VIN to confirm your 2023-2024 Fccc MT50E or Saf-T-Liner C2 Jouley is included in this recall.
- Call Fccc customer service at 1-800-547-0712 to confirm whether the dealer inspection and fastener tightening is open for your VIN.
- Contact a franchised Fccc dealer after Fccc confirms the repair is open; the dealer secures the high-voltage inverter cable fasteners to help prevent loss of drive power.
- Bring the owner letter if you have it. If not, reference recall number 23V879 when you call.
- Drive cautiously until the repair is complete, and pull over safely if the bus loses drive power.
What happens at the repair
At the dealer, an Fccc technician will inspect the high voltage inverter cable fasteners and tighten loose fasteners as needed to secure the cable. The final dealer repair will be free once available. Do not assume the dealer can complete it until the repair is open for your VIN. If you already paid for a related repair before the owner letter, the reimbursement plan directs owners to seek reimbursement through authorized dealers. Bring the repair order and payment documentation to that dealer so the claim can be reviewed.
