Issue: On certain travel trailers, the frame rail may not be properly supported where the draw bar is attached. As a result, the frame could bend, which could cause poor vehicle handling. Safety Risk: A sudden change in vehicle handling could increase the risk of a loss of control, and may result in a crash. Corrective Actions: Keystone will notify owners by mail and instruct you to take your travel trailer to a dealer to add reinforcement plates to the frame.
- Electrical#2019426
266 units affected
Issue: On certain motorhomes, there may be a loose connection between the battery cables and the Battery Isolation Manager (BIM) or the Battery Isolation Relay (BIR). A lose connection could cause a premature failure of the BIM/BIR and/or cause electrical arcing (sparks). Safety Risk: Electrical arcing could create the risk of a fire. Corrective Actions: Thor Motor Coach will notify owners by mail and instruct them to take their vehicle to a dealer to install lock washers to secure the battery cable to the BIM/BIR. The BIM/BIR will be replaced as necessary.
- Suspension#2018302
34 units affected
On certain motorhomes, the rear axle U-bolts may not have been properly tightened during installation. These bolts could loosen or break, potentially resulting in a separation of the rear axle from the vehicle. This could cause a loss of control and increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect and tighten the U-bolts as necessary.
- Accessories#2017613
6,579 units affected
On certain motorhomes equipped with Kidde fire extinguishers with black plastic handles and valves, the fire extinguishers may become clogged or require excessive force to activate. Also, the nozzle may detach from the valve assembly with enough force that it could cause injury, and fail to discharge. In case of fire, failure of the extinguisher to function could result in injury and/or property damage. Correction: Owners will be provided with instructions on how to inspect the fire extinguisher to see if it is recalled. Replacement fire extinguishers will be supplied by Kidde directly.
