Correction: Daimler Trucks North America authorized service facilities will replace the throttle pedal.

• Steering#2016304June 14, 2016

  19 units affected

  On certain motorhomes, the power steering fluid temperature may exceed the hose material rating. This could cause the power steering hose to rupture without warning during low-speed driving. A leaking power steering hose could result in the loss of power steering assist and increased steering effort, which depending on the driver's reactions and traffic conditions, could increase the risk of a crash resulting in injury and/or damage to property. Correction: Dealers will replace the affected power steering hose with one that has a higher temperature rating.

• Brakes#2016205May 9, 2016

  100 units affected

  On certain motorhomes equipped with a heavier weight adjustable 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.

• Accessories#2015573November 25, 2015

  93 units affected

  Certain motorhomes may have been manufactured with a refrigerator equipped with a travel latch that could inadvertently activated without the users knowledge.

Correction: Dealers will replace the wiper blades with a new updated model.

• Electrical#2014425September 30, 2014

  133 units affected

  On certain motorhomes, the refrigerator heated water line circuit breaker may have the wrong size amperage rating and the 12 volt thermostat and 12 volt heated water line could also be wired incorrectly, causing it to have the incorrect wiring or no power. The incorrect circuit breaker amperage rating could increase the risk of a fire causing injury and/or damage to property. Correction: Dealers will check circuit breaker amperage and correct any wiring issues for thermostat and/or heated water line.

• Accessories#2014066March 4, 2014

  65 units affected

  On certain vehicles equipped with Frigidaire KG series microwaves, a defect in the microwave oven keypad could cause the oven to activate without pressing any keys.

• Electrical#2012425December 12, 2012

  66 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.
