• Lights And Instruments#2023698December 22, 2023

  55 units affected

  Issue: On certain vehicles, the tail lamps don't turn on when the daytime running lamps (DRLs) are on. Canadian regulations require that, if a vehicle has dash backlighting, the low beam headlamps and tail lamps must automatically switch on when it's dark or the tail lamps must stay on at all times. Safety Risk: Driving without tail lamps in low light conditions could make the vehicle less visible and increase the risk of a crash. Corrective Actions: Prevost will notify owners by mail and advise you to take your vehicle to a Prevost service center to update the vehicle software.

• Brakes#2023641December 1, 2023

  19 units affected

  Issue: On certain buses equipped with the optional driver assist system, the front radar sensor may be blocked by the front bumper trim panel. As a result, the system may not detect when there is an obstacle in front of the bus and would not automatically apply the brakes. The system may also activate automatically and apply the brakes without an obstacle. Safety Risk: Vehicle safety systems that do not work correctly could increase the risk of a crash. Corrective Actions: Prevost will notify owners by mail and advise you to take your bus to a Prevost service center to inspect and, if necessary, replace the front bumper trim panel.

• Electrical#2023608November 10, 2023

Prevost will also inspect and, if necessary, replace any damaged components.

• Lights And Instruments#2023378July 12, 2023

  60 units affected

  Issue: On certain buses, the right-front turn signal lamp could fail when the turn signal or hazard warning lights are turned on. Safety Risk: A turn signal that doesn't work may cause a person not to recognize when a driver intends to turn or change lanes. A hazard lamp that doesn't work could make the vehicle less visible. Both could increase the risk of a crash. Corrective Actions: Prevost will notify owners by mail and provide you with directions for completing the recall repairs. The repair will include installing improved headlight wiring.

• Lights And Instruments#2023379July 11, 2023

  31 units affected

  Issue: Certain buses were built with daytime running lamps (DRLs) that don't turn off when the fog lights are switched on. Canadian regulations require the DRLs to turn off when the front fog lamps are switched on. Safety Risk: Daytime running lamps that stay on in foggy conditions could cause glare and reduced visibility. This could increase the risk of a crash. Corrective Actions: Prevost will notify owners by mail and advise you to take your bus to a Prevost service center to update the daytime running lamp software.

• Lights And Instruments#2023154March 20, 2023

• Engine#2022191April 14, 2022

  1,219 units affected

  Issue: 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. Safety Risk: An overheated alternator bearing could create the risk of a fire. Corrective Actions: 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.

• Powertrain#2019642December 17, 2019

  7 units affected

  Issue: On certain buses, the driveshaft clamp bolts may not be properly tightened. As a result, the driveshaft could detach. This could cause a loss of power to the drive wheels and disable the bus. It could also cause the driveshaft to detach completely from the vehicle. Safety Risk: A bus that is disabled could result in a transfer of passengers in an uncontrolled environment, which may create a risk of injury. Additionally, a driveshaft that separates from the vehicle could create a hazard for others nearby and increase the risk of a crash.

Correction: Dealers will inspect and, if necessary, replace the drag link turnbuckle assembly.

• Other#2013059February 19, 2013

  465 units affected

  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.

• Lights And Instruments#2013017January 17, 2013

  10 units affected

Correction: Dealers will insulate the AFSS thermal detector.

• Other#2012203July 5, 2012

  98 units affected

  On certain vehicles, a component of the Automatic Fire Detection and Suppression System may have been installed incorrectly and could contact or rub against brackets and clamps. As a result, the system may inadvertently activate causing, amongst other things, the engine to stop. Engine stalling would result in lost vehicle propulsion which, 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 inspect and, if necessary, replace the linear thermal detector.

• Other#2012191June 28, 2012

  400 units affected
