2011 Prevost X3-45 Coach Recall

On certain vehicles, if the front bearing on the alternator fails, the alternator belts could continue to turn the alternator. This could cause the alternator bearing to overheat.

An overheated alternator bearing could create the risk of a fire.

Prevost will notify owners by mail and instruct you to take your vehicle to a Prevost service center to replace the alternator belts. To reduce the safety risk, Prevost recommends that you should inspect the front bearing on the alternator regularly, and not operate the engine with a defective alternator.

On certain vehicles, the steering drag link turnbuckle may crack and fracture over time. If this were to occur, it could result in a complete loss of steering control, which would create a risk of a crash causing injury and/or property damage. Correction: Dealers will replace the steering drag link.

A failure of this component (steering) may increase the risk of a crash or injury.

On certain vehicles, the Vehicle Certification Label contains incorrect front and rear tire pressure rating. The correct tire pressure rating is 120 psi. Incorrect tire pressure information may lead to overinflation of tires and could affect vehicle stability, braking and traction, potentially resulting in a loss of control or increased braking distances. This could result in a crash causing injury and/or property damage. Correction: Dealers will replace affected labels.

A failure of this component (label) may increase the risk of a crash or injury.

A failure of this component (suspension) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain vehicles, the engine calibration for the “limp home” mode was inadvertently set too high at 1750 rpm instead of 1200 rpm. Should the “limp home” mode be activated, the increased idle speed may cause sudden and unexpected acceleration, which could result in very high vehicle speeds and make it difficult to slow or stop the vehicle if the transmission is not shifted into neutral. This could result in a crash causing property damage and/or personal injury. Correction: Dealers will install updated engine calibration software.

A failure of this component (other) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain vehicles, the thermal detector could become damaged, causing inadvertent activation of the Automatic Fire Detection and Suppression System (AFSS), which would result in engine shut down. Loss of vehicle propulsion, in conjunction with traffic and road condition, and the driver’s reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will insulate the AFSS thermal detector.

A failure of this component (other) may increase the risk of a crash or injury.
