What's wrong?
The battery isolation manager or battery isolation relay in these 2020 Thor Motor Coach motorhomes sits between the battery cables and the motorhome's electrical system. Its job is to manage how the chassis battery and coach batteries connect, so charging and 12-volt power are controlled without draining the wrong battery bank.
On affected Chateau, Daybreak, Four Winds, Freedom Elite, Majestic, Outlaw, and Quantum motorhomes, the battery cable connection at that manager or relay is loose. Thor Motor Coach traced the problem to the way the part is mounted and how the cable ring connectors bend as the other cable ends are connected to the chassis battery. A loose high-current battery connection can arc, overheat, and damage the isolation manager or relay.
There is no warning sign before failure. Thor Motor Coach did not identify a dashboard message, noise, or other early cue, so owners should not wait for a symptom before arranging the free recall inspection and repair.

What's the safety risk?

What should I do?
- Check your VIN to confirm your 2020 Thor Motor Coach Majestic, Daybreak, Chateau, Outlaw, Four Winds, Freedom Elite, or Quantum motorhome is included in this recall.
- Contact a franchised Thor Motor Coach dealer to schedule the free lock-washer installation that secures the loose battery cable and checks the BIM or BIR.
- Bring the recall notice if you have it, and reference recall number 19V609 when you call.
- Avoid unnecessary use until the repair is complete because the loose connection can arc and increase fire risk.
What happens at the repair
At the dealer, a Thor Motor Coach technician installs lock washers to secure the battery cable to the battery isolation manager or battery isolation relay. If the cable was loose, the technician also replaces the BIM/BIR. The recall repair is free, including parts and labor. Thor Motor Coach's general reimbursement plan covers eligible documented out-of-pocket repairs tied to this defect. Bring prior repair paperwork to the service desk when you arrive.
