• Brakes#2016593November 25, 2016

  46 units affected

  On certain motorhomes equipped with a heavier weight adjustable offset foot pedal, the brake activation signal to the motorhome’s brake lights and to certain towed devices may not deactivate when the motorhome service brakes are released. This may cause the motorhome brake lights to potentially remain illuminated, which would result in the following road users being unaware of the driver's intentions. Additionally, if the brakes of a towed vehicle were to remained engaged, it could result in a loss of vehicle control. Both of these conditions could increase the risk of a crash causing injury and/or damage to property. Daimler Trucks North America authorized service facilities will replace the torsion spring of the pedal assembly with an improved spring.

• Steering#2016592November 25, 2016

Correction: Dealers will inspect and, as necessary, replace the steering gear mounting bracket, or install a support bracket.

• Electrical#2013009January 14, 2013

  153 units affected

  On certain vehicles, the connector for the brake and cruise control signal diode jumper assembly may come loose, resulting in a possible intermittent or continuously open circuit. Two circuits are potentially affected. One circuit disengages the cruise control with brake pedal application, and the other circuit illuminates the brake lights with brake application. Failure of the cruise control to disengage, or of the brake lights to illuminate when the brake pedal is depressed, could result in a crash causing property damage and/or personal injury. Correction: Dealers will verify that the locking tabs on the diode jumper assembly connector are fully engaged and locked into place.

• Engine#2012443December 21, 2012

  68 units affected

  On certain vehicles equipped with Cummins EPA 2010 ISL engines, insufficient shielding is installed between the exhaust pipe and the floor.

  Certain motorhomes equipped with a Spartan chassis may experience an unintended increase in vehicle speed after the cruise control is set. Then, if the brake is applied and released, cruise control function may resume and the vehicle speed may continue to increase. An unexpected moderate increase in vehicle speed may go unnoticed by the driver and, depending on traffic and road conditions, and the driver's reactions, could result in a crash causing property damage and/or personal injury. Correction: Owners are advised to contact Spartan Motor Chassis, Inc. at 800-393-8861, to locate an authorized repair facility. The remedy consists of replacing the cruise control switch and reprogramming the control module.

• Engine#2011358October 4, 2011

  10 units affected

  On certain motorhomes 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.

• Brakes#2011320August 25, 2011

  118 units affected

  On certain motorhomes, 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.

• Accessories#2011050February 2, 2011

  598 units affected

  Certain refrigerators used in Recreational Vehicles (RVs) contain either a sensing algorithm or a thermal switch to interrupt power when it detects high temperatures that could lead to a fire. An insufficient response time can result in the power not being shut-off in sufficient time to prevent a fire, which could result in property damage and/or personal injury. Correction: Dealers will install a thermocouple with a faster response time for all refrigerators with a sensing algorithm or a thermal switch.

  On certain motorhomes, the Atwood 35-series range oven, model number beginning with RV1735, RV2135, RA1735, or RA2135, may develop a small crack within the line delivering gas to the oven cavity burner. A propane leak, in the presence of an ignition source, could result in a fire and/or explosion, causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the oven supply tube.

• Brakes#2010007January 18, 2010

  28 units affected

  On certain vehicles equipped with an adjustable brake pedal assembly, a drive pin that is below specification may become disengaged from the brake arm, causing separation or loosening of the pedal from the remainder of the assembly. If the drive pin becomes disengaged from the brake pedal assembly it could result in a loss of vehicle braking function and/or cause the brake pedal to interfere with the throttle pedal. Either condition could result in a vehicle crash causing property damage, personal injury or death. Correction: Dealers will install a secondary pin retention system.
