What's wrong?
The driveshaft on 2020 Prevost X3-45, H3-45 Vip, and H3-45 buses is the rotating shaft that carries engine power through the driveline to the wheels. Clamp bolts hold the driveshaft connections tight so the shaft stays aligned while it turns under load. That clamp pressure matters because the driveline is moving whenever the bus is being driven.
On the affected buses, the problem is not a defective driveshaft part. The clamp bolts were tightened during assembly with a tool that was not torque controlled, after a new assembler was assigned to that workstation. Without the correct torque, the bolts can loosen as the vehicle moves. A loose driveshaft connection can create vibration and unsafe driveline movement if it is not corrected.
Owners or drivers can notice vibration from the driveshaft during vehicle movement as the bolts loosen. That vibration is the warning sign to report before the bus is driven farther.
Who's affected?
Covers X3-45, H3-45 Vip, and H3-45 coaches, with the same driveline component listed for each model.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
A separated driveshaft connection can cause loss of drive. A detached driveshaft section can also become a road hazard, and either condition increases crash risk. If you feel new vibration while the vehicle is moving, slow down, stop where safe, and contact a Prevost dealer. Repair is free at any franchised Prevost dealer.
What should I do?
- Check your VIN to confirm your 2020 Prevost X3-45, H3-45 Vip, or H3-45 is included in this recall.
- Contact a franchised Prevost dealer to schedule the free driveshaft clamp-bolt repair that properly tightens the driveline connection.
- Bring the recall notice if Prevost mailed one. If not, reference recall number 19V900 and Prevost recall SR19-43 when you call.
- Drive cautiously until the repair is complete, since a separated driveshaft connection can cause loss of drive or create a road hazard.
What happens at the repair
At the dealer, a Prevost technician replaces the driveshaft clamp bolts and tightens them to the correct specification. The recall repair is free, with parts and labor covered. Prevost has a general reimbursement plan on file for owners who already paid for this same driveshaft clamp bolt repair before the recall notice. Bring repair invoices and payment documentation to the Prevost service desk, or contact Prevost customer service to ask how to submit the claim.
