Recall 12V303 affects 400 2007-2011 Prevost X3-45 and H3-45 coaches for an accelerator-pedal sensor defect. Repair is free at any franchised Prevost dealer.
Prevost is recalling 400 2007-2011 X3-45 and H3-45 coaches with Volvo D13 engines under recall 12V303 because the accelerator pedal throttle position sensor can stay at idle. When that happens, the coach stops responding to accelerator input and can stop in traffic, increasing crash risk; the dealer repair will be free once available.

What's wrong?
The accelerator pedal on 2007-2011 Prevost X3-45 and H3-45 coaches with Volvo D13 engines uses a throttle position sensor. That sensor turns pedal movement into an electrical signal for the engine controls. When the driver presses the pedal, the engine control system uses that signal to increase power.
On affected coaches, the sensor can become inoperative because it sends a permanent idle signal. In plain terms, the engine controls keep reading the pedal as if the driver is not asking for acceleration. The pedal itself is the driver's command, but the engine stays at idle instead of responding to that command.
There is no warning sign before failure. The driver is most likely to notice the problem when pressing the accelerator and the coach does not pick up speed as expected.

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 failed accelerator pedal throttle sensor can make the vehicle stop responding to accelerator input. If that happens in traffic, the vehicle can come to a stop and increase the risk of a crash. Schedule the recall repair promptly and avoid continuing a trip after any loss of accelerator response. Repair will be free at any franchised Prevost dealer once available.
What should I do?
- Check your VIN to confirm your 2007-2011 Prevost H3-45 or 2009-2011 Prevost X3-45 coach is included in this recall.
- Contact Prevost customer service at 1-418-883-2888 to confirm repair scheduling for your coach.
- Schedule the free accelerator-pedal throttle-sensor replacement that fixes the idle-signal fault and restores accelerator response.
- Bring the recall notice if Prevost mailed one. If not, reference recall number 12V303 when you call.
- Drive cautiously until the repair. Leave extra space and move out of traffic if the coach stops responding to accelerator input.
What happens at the repair
The current remedy status is not listed here. The listed repair is straightforward: once the dealer repair is available for your VIN, a Prevost technician replaces the accelerator pedal throttle sensor. That repair addresses the permanent idle signal that can leave the throttle position sensor inoperative. Prevost's filing says owner notices began on July 13, 2012. The final dealer repair will be free once available, with parts and labor covered under the recall.
