An electrical short could result in a vehicle fire causing property damage and/or personal injury. Correction: Authorized repair facilities will inspect and, if necessary, reroute the grid heater relay ground wire.

• Engine#2011338September 13, 2011

  400 units affected

  On certain school 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.

• Accessories#2011142March 29, 2011

  On certain vehicles equipped with an MBE900 (EPA04 and EPA07) engine, the intake air grid heater may short circuit and fail. This could result in a vehicle fire causing property damage and/or personal injury. Correction: Dealers will install an additional external relay to prevent battery connection to the grid heater when the vehicle is not running and when grid heater control signal is absent.

  On certain vehicles, the weld around the steering shaft tube, which joins the splined tube to the non-splined intermediate tube, may be mislocated. An improperly located weld bead may allow the splined tube and non-splined tube to rotate relative one another during a low speed, high torque turn, resulting in a possible separation of the tubes. This could cause a loss of steering control which could result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the steering shaft.

  On certain school buses equipped with a hybrid transmission with PARK feature, the reverse idler shaft may contact the PARK feature and the two components may bind, preventing the PARK feature from engaging. Should an operator place the transmission in PARK and exit the vehicle without properly applying the parking brakes, the vehicle could roll away, which could result in a crash causing property damage, personal injury or death. Correction: Dealers will install a reverse idler shaft retention kit.

  On certain vehicles, the stop lamps may operate intermittently during light braking applications. Failure of the brake lamps to illuminate when the brakes are applied may result in the following road users being unaware of the driver's intentions, increasing the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the hydraulic brake light switch assembly.

  On certain school buses, the switch used to detect the position of the air operated front entrance door may malfunction, causing the warning lights and crossing arm to operate improperly. The malfunction of warning lights increases the risk of injury or death to students during the loading/unloading process. Correction: Dealers will replace the affected switch with a more robust unit.

  311 units affected

  On certain vehicles, the right front crossover brake line may have been installed incorrectly. As such, the brake line may contact nearby components, eventually causing a brake fluid leak which could result in a reduction of braking capability. Increased stopping distances could result in a vehicle crash causing property damage, personal injury or death. Correction: Dealers will inspect and, if necessary, replace the brake line fastening clamps.

• Suspension#2009341December 1, 2009

  506 units affected

  On certain vehicles, fasteners used to connect the rear suspension spring to the suspension hanger bracket may not have been torque to specification during vehicle assembly. Under torqued fasteners may loosen and fall out, allowing the rear suspension to become misaligned. This could result in a vehicle crash causing property damage, personal injury or death. Correction: Dealers will torque fasteners to specs.

  552 units affected

  On certain vehicles, the adjustable brake pedal arm may loosen, rotate around its shaft, and swing in front of the accelerator pedal. Should the brake pedal arm contact and engage the accelerator pedal, it could result in extended stopping distances and a vehicle crash causing property damage, personal injury or death. Correction: Dealers will install a C-clamp assembly to the brake pedal arm.

  On certain school buses, a production change may end-up reducing the effective life of the stop arm lights. Should the lights fail, visibility of a stopped bus would be affected. This could increase the risk of a child or pedestrian being struck by a passing motorist, causing severe personal injury or death. Correction: Dealers will replace the safety stop arm light kit.

  On certain buses, the entrance door glass may be inadequately bonded to the door frame. As such, the glass may separate from the door assembly and strike a vehicle, property, or a bystander, which could result in property damage, personal injury or death. Correction: Dealers will affect repairs.

• Steering#2009223July 21, 2009

  158 units affected

  On certain vehicles, an incorrect weld on the steering shaft tube assembly may allow the splined tube and the non-splined tube to rotate relative to one another during a low speed, high torque turn, possibly resulting in a separation of the two tubes. This could result in a loss of steering control and a crash cause property damage, personal injury or death. Correction: Dealers will inspect and, if necessary, replace the steering shaft assembly.

• Brakes#2009173June 9, 2009

  40 units affected

  On certain vehicles, a quick release valve (QRV) contains a rubber diaphragm that may delaminate and cause leakage, a restriction, or blockage of the airflow, thereby affecting pressure delivery and release to the foundation brakes. Air trapped in the spring brake chambers could cause the parking brakes to apply slower than expected, which could allow the vehicle to roll away causing a risk of property damage, personal injury or death. Correction: Dealers will inspect and replace defective quick release valves.

  On certain buses, passenger clothing (drawstrings, straps, etc.) could become caught as the passenger exits the front door of the bus. If this happens and goes unnoticed by the driver before he/she pulls away, the passenger could be dragged by the bus, causing serious injury or death. Correction: Dealers will inspect and, if required, relocate the handrail.
