What's wrong?
The dash illumination dimmer on the 2020 Prevost H3-45 and X3-45 is supposed to let the driver lower or raise the brightness of the instrument-panel controls and indicators. That dimmer uses a potentiometer, a small electrical control that changes resistance so the lighting level changes instead of staying fixed. At night, the driver relies on that adjustment to keep the controls readable without excessive glare.
On affected coaches, the potentiometer and related wiring were not installed after the supplier discontinued the component. Without that control in the circuit, the dash illumination stays at its highest brightness setting. The controls and indicators still light up, but the driver cannot reduce the intensity to match nighttime driving conditions.
The warning sign is present as soon as the coach is started in nighttime conditions. The driver will notice the controls and indicators are very bright and cannot be dimmed.

What's the safety risk?
At night, the highest dash brightness can reduce the driver's outside visibility and increase the risk of a crash. If the controls or indicators look unusually bright after startup, lower speed, leave extra space, and schedule the recall repair soon. Repair is free at any franchised Prevost dealer.
What should I do?
- Check your VIN to confirm your 2020 Prevost H3-45 or X3-45 is included in this recall.
- Contact a franchised Prevost dealer to schedule the free potentiometer and wiring repair that lets the driver dim the dash illumination.
- Bring the recall notice if Prevost mailed one. If not, reference recall number 19V777 when you call.
- Limit night driving until the repair is complete if the dash illumination is stuck at full brightness.
What happens at the repair
At the dealer, a Prevost technician installs the missing potentiometer component and the required wiring for the dash illumination controls. That repair restores the driver's ability to adjust the brightness of the controls and indicators instead of leaving the dash at its highest brightness setting. Parts and labor are covered under the recall, so the dealer repair is free. Prevost also lists SR19-42 as its internal recall number for this repair.
