Corrective Actions: Thor Motor Coach will notify owners by mail and instruct you to bring your motorhome to a dealer to inspect the exterior ladder. It will be reinforced or relocated, as necessary.

On certain motor coaches, the windshield wiper system could have been installed incorrectly during the assembly process. If one or both windshield wipers were to fail during use, a driver's visibility could be restricted, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect and replace the wiper system as necessary.
- Accessories#2018397
13 units affected
On certain ACE 27.2 motorhomes, the rubber liquid propane (LP) hose may sag and rub on the right rear tire. This could cause a propane leak, which, in the presence of an ignition source, could result in a fire causing injury and/or damage to property. Correction: Dealers will inspect the routing of the rubber LP hose and repair 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.

- Visual System#2017434
33 units affected
On certain motorhomes, the windshield wiper system may have been incorrectly installed and secured. This could result in the wiper system being loose, which could limit the driver’s visibility under certain conditions which may increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the wiper system to verify that the original recall repair was completed correctly, and will repair as necessary. Note: This recall supersedes recalls 2017-078 and 2017-172. A portion of vehicles repaired under the previous recall will require re-inspection and repair.
- Visual System#2017172
454 units affected
On certain motorhomes, the windshield wiper system may have been incorrectly installed and secured. This could result in the wiper system being loose, which could limit the driver’s visibility under certain conditions which may increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the wiper system for correct installation, and if required, the wiper nut(s) will be tightened to specification.
- Accessories#2016383
289 units affected
Certain motorhomes may not comply with Canada Motor Vehicle Safety Standard (CMVSS) 302 – Flammability of Interior Materials. The shower door installed in the vehicle does not meet the requirements of the standard, which could enhance the spread of a flame in the event of a fire. This could result in injury and/or damage to property. Correction: Dealers will replace the shower door with a material that meets the requirements of the standard.
- Seats And Restraints#2016268
7 units affected
Certain motorhomes may fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 210 – Seat Belt Anchorages. During production, the floor that was installed did not have the proper reinforcement brackets and plates, and as a result, the seat belt anchorages located in the slide out of the motorhome fail to meet the attachment strength requirements of the standard. This could result in seat belts detaching from the vehicle in a crash, thereby failing to properly restrain occupants and would increase the risk of injury. Correction: Dealers will install the required reinforcement brackets and plates to insure the seat belt attachments meet the strength requirements of the CMVSS 210 standard.
- Electrical#2013217
763 units affected
On certain motorhomes, the Battery Control Center (BCC) could fail while the vehicle is underway. This would cause the engine to stall and all electrical components to become inoperative. Engine stalling would result in a loss of vehicle propulsion. Failure of the lighting system may result in the following road users being unaware of the driver intentions. It could also compromise the driver’s ability to see the road and its users, as well as reducing vehicle conspicuity during hours of darkness. In conjunction with traffic and road conditions, and the driver’s reactions, these issues could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will correct the BCC electrical connection to the chassis.
- Other#2012058
144 units affected
On certain motorhomes, the cable for the transmission range indicator "PRND321" on the instrument cluster may be damaged by a sharp edge on the shift lever arm. If the indicator cable is cut, the indicator will remain in the "1" position (first gear) regardless of what gear is actually selected. With no gear indication, the operator may inadvertently select an incorrect gear, increasing the risk of a crash causing property damage and/or personal injury. Correction: Ford dealers will replace the transmission selector arm and indicator assembly.
