Transport Canada recalls

Engine#2014090March 24, 2014
157 units affected
On certain vehicles equipped with Cummins compressed natural gas engines, incorrect engine ECU programming could cause the exhaust system temperature to become elevated during cold weather operation. This could also cause flames to be emitted from the exhaust. As a result, nearby combustible material could be ignited, increasing the risk of a fire, injury and/or damage to property. Correction: Authorized Cummins service facilities will update software programming.
Engine#2014052February 21, 2014
123 units affected
On certain vehicles equipped with Cummins ISL engine, the exhaust pipe may disconnect from the muffler/catalyst. If this occurs on a twin-steer configured vehicle where the vehicle is operated from the right side, the operator may be exposed to carbon monoxide, which could result in asphyxiation or carbon monoxide poisoning. Correction: Dealers will install a different length exhaust flex pipe and a turbocharger outlet pipe to reduce rigidity of the exhaust to address this condition.
Suspension#2012065February 20, 2012
182 units affected
On certain trucks, the front axle beam may have been manufactured incorrectly. In certain application the load on the axle could allow stress cracks to form which, over time, may cause the axle beam to fail. This could result in a vehicle crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if required, replace the axle beam.
Electrical#2011148April 1, 2011
109 units affected
On certain vehicles, the rearview mirror switch (mounted on the dashboard) may overheat, causing the plastic to melt. An overheated switch may not allow rearview mirror remote adjustability and, as such, the driver may not have full use of the mirrors. In addition, excessive heat can cause smoke within the instrument panel, which could distract the vehicle operator and result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect the rearview mirror switch and install a relay wiring harness. Switches that show signs of overheating will be replaced.
