What's wrong?
The shower curtain in affected 2012-2017 Thor Motor Coach Ace, Road Bear Rental, Citation, Four Winds, and Siesta motorhomes is an interior material near the shower area. Its normal job is simple: contain water while staying flexible, secured, and resistant to ignition under the federal flammability standard for interior materials.
On these motorhomes, the flexible PVC used to make the shower curtain does not meet FMVSS 302. That standard covers how interior materials resist burning when exposed to an ignition source. If flame reaches the curtain, the curtain can catch fire instead of slowing or resisting ignition as designed.
There is no warning sign before failure. The curtain will not look or feel unsafe before an ignition source exposes the problem. Treat the issue as a material defect, not a wear item or maintenance issue.

- Bring the recall notice if Thor Motor Coach mailed one, or reference recall number 16V571 when you call.
- Keep ignition sources away from the shower curtain area until the fire-retardant curtain is installed.
What happens at the repair
At the dealer, a Thor Motor Coach technician replaces the shower curtains with fire retardant curtains that meet the recall remedy. The replacement curtains and labor are free under the recall. Thor Motor Coach has a general reimbursement plan on file for owners who already paid for this shower curtain repair before the recall work was completed. If that applies to you, ask Thor Motor Coach customer service or the dealer service desk what documentation is required for a reimbursement claim.
