My front cap has been leaking for about a year, and I have had it "repaired" three times already under warranty. It is still leaking, and, in fact, it may be getting worse. This cap contains, among other things, a nearly queen-sized bed for sleeping. I have read on Thor forums that countless other owners are having similar problems, which stems from the front cap not being secured/installed correctly. This includes missing seals and/or missing screws. My fear is that this cap will continue to sag/loosen and eventually fall/break off while I am driving, or while someone is sleeping in this area. This potentially could result in fatalities / loss of human life.

- Risk
- Improperly assembled recliner mechanism may have reduced strength and may not adequately restrain an occupant in a crash, increasing the risk of injury.
- Remedy
- Ford has notified TMC owners, and Ford dealers will inspect the seat structures and replace them, as necessary, free of charge. The recall began October 21, 2019. Owners may contact Ford customer service at 1‑866‑436‑7332 or TMC customer service at 1‑877‑855‑2867. TMC's number for this recall is RC000178.
