Correction: Nova Bus will provide fleet operators with directives to inspect and tighten the various steering components fasteners to specifications.

• Engine#2011381October 26, 2011

  252 units affected

  On certain buses equipped with a Cummins engine, the V-band clamps used to connect the inlet and outlet cone sections to the Diesel Oxidation Catalyst (DOC) / Diesel Particulate Filter (DPF) include a T-bolt which can fracture and fail when subjected to stress or load. A fracture or failure of the T-bolt may cause the clamp to loosen and the inlet or outlet sections attached to the DOC/DPF housing to disconnect. Should this occur, hot exhaust gases can vent prior to exiting the tailpipe, creating a risk of combustion or damage to adjacent materials, which could result in a vehicle fire. If both clamps fail, the DOC/DPF housing could detach completely, separate from the vehicle, and strike another vehicle, stationary object, or bystander. These issues could result in property damage and/or personal injury. Correction: Cummins will install updated V-band clamps.

• Label#2011177April 26, 2011

  45 units affected

  Certain buses fail to comply with the requirements of Canada Motor Vehicle Safety Standard 120 - Tire Selection and Rims. The Cargo-Carrying Capacity label does not contain correct tire pressure information. The label incorrectly indicates tire pressures of 115 kPa / 793 psi, instead of 793 kPa / 115 psi. Improper tire pressure can lead to tire failure which, in turn, can result in a crash causing property damage and/or personal injury. Correction: Updated labels will be mailed to owners of affected vehicles, along with instructions for proper installation.

• Steering#2011110March 8, 2011

  On certain buses, the drag link fasteners may not have received adequate tightening torque during vehicle assembly. This could allow the drag link to disconnect, which could result in a loss of vehicle control. A loss of steering control could result in a crash causing property damage and/or personal injury. Correction: Dealers will tighten drag link fasteners to specifications. Note: This recall supersedes recall 2010311.

• Engine#2010389November 5, 2010

  1,215 units affected

  On certain vehicles, incorrect bolts were used on the engine supports and have not been tightened to proper specifications. The bolts may wear prematurely and subsequently break. When some of the bolts break, vibration and noise is induced in the structure which will prompt the driver to check his vehicle. If all bolts were to break at same time, the engine will always be supported by one end of the structure and the other end will be supported by the drive shaft causing enormous vibration and noise alerting the driver to park his the vehicle immediately in a safe area. Correction: Dealers will replace the engine mount fasteners.

• Steering#2010311September 15, 2010

• Brakes#2010226July 12, 2010

  2,071 units affected

  On certain buses, there may be interference within the V-BEA multiplex communication network. Whenever the parking brake, or the vehicle's brake interlock is applied, the Automatic Traction Control (ATC) system's sensors could falsely detect the movement of a wheel. The ATC system could misinterpret this situation as wheel spin, subsequently applying and releasing the applied brakes. The vehicle could then move unexpectedly and cause a crash resulting in property damage, personal injury or death. Correction: Reprogramming procedures will be provided to affected vehicle fleet operators

• Fuel System#2010065March 3, 2010

• Engine#2010021January 28, 2010

  172 units affected

  On certain vehicles, the flywheel housing support bolts may not have been tightened to proper specifications. As a result, the bolts may wear prematurely and break. Should bolts break, vibration and noise would be induced which will prompt the driver to check the vehicle. If all bolts were to break at same time, the engine would be supported by one end of the structure and the other end will be supported by the drive shaft causing enormous vibration and noise. Correction: Dealers will replace the rear flywheel housing support bolts and tighten them to proper specifications.

• Steering#2009253August 27, 2009
