IMPORTANT SAFETY RECALL
This notice applies to your vehicle: «VIN»

Dear «Owner_name»:
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. Thor Motor Coach
(TMC) has decided that a defect which relates to motor vehicle safety exists in certain model year 2020/2021 Chateau, Daybreak, Four
Winds, Freedom Elite, and Quantum motorhomes. As a result, TMC is conducting a safety recall. We apologize for any inconvenience
this action may cause you; however your safety and continued satisfaction are of the utmost importance to us.
It has been discovered that on certain model year 2020/2021 Chateau, Daybreak, Four Winds, Freedom Elite,
and Quantum Motorhomes built on a Chevy chassis, expansion and contraction of the plastic body of the
BIM (battery Isolation Manager)/BIR (Battery Isolation Relay) from heat in the engine compartment causes
it to be susceptible to moisture inside the body, which in turn produces arcing of the internal components.
This internal arcing can cause heating, or the possibility of a fire.
TMC has contacted your selling dealer and has instructed them on how to replace the BIM/BIR. This will
be done at no cost to you the owner. The remedy should take approximately 45 minutes to perform.
At your earliest convenience, please contact your dealer and schedule an appointment to have this remedy
completed. To locate the nearest authorized TMC service center, please visit

Thor Motor Coach (TMC) decided that a defect which relates to motor vehicle safety exists in certain models of the below listed motorhomes.

The required action is to replace the BIM/BIR with a Trombetta solenoid.
