What's wrong?
The LPDM relay on the 2018 Ic Bus Ce is an electrical switch inside the liquid propane gas fuel system. On buses with the 8.8L LPG engine, that relay controls power to the propane booster pump and scavenge pump. Those pumps keep fuel moving at the pressure the engine needs to run.
In the recalled relay, an adjustable spring controls how firmly the electrical contacts touch. That spring was misadjusted at the relay manufacturer. When contact pressure is wrong, the relay can lose contact and shut off power to the fuel pumps. If the fuel pumps stop, the engine can stumble or stall during operation.
There is no warning sign before failure. The bus can run normally until the relay loses contact, so a driver is not given a clear symptom before the fuel pump stops.
Who's affected?
The electrical system and fuel pump are both listed for the same 2018 Ic Bus Ce buses.

Not every 2018 Ic Bus Ce bus is on the list. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
If the fuel pump stops, the bus will stall and increase the risk of a crash. There is no warning sign before failure, so take any stall seriously and schedule the relay replacement soon. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2018 Ic Bus Ce is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free LPDM relay replacement that fixes the fuel-pump relay failure.
- Bring the recall notice if one was mailed. If not, reference recall number 18V127 when you call.
- Limit bus use until the repair is complete, since a stopped fuel pump can stall the bus.
What happens at the repair
At the dealer, an Ic Bus technician replaces the LPDM relay for the propane booster pump and scavenge pump. The replacement parts and labor are free under the recall. If you already paid out of pocket for an LPDM relay or related fuel pump repair before the owner notice, the Ic Bus standard reimbursement plan applies. Follow the reimbursement instructions included in the customer notification and keep repair paperwork for the claim.
