Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

The secondary alternator (Balmar model XTMS 170 K6) overheated and failed. An RV Mechanic and a licensed professional engineer is saying luckily there was no fire. After some research, this seems to be a common issues with these Balmar alternators. The same alternator is installed on certain Winnebago RVs (Revel and Ekko) and they have issued various bulletins (23V-663) noting that the secondary Balmar alternator setup could experience severe thermal runaway. If left unaddressed, the extreme heat poses a severe fire risk. Thor has explained that because Winnebago is a larger company that Balmar has stepped up for their demands on a recall but Thor hasn't been able to get Balmar to issue a recall for the same alternator installed on Thor vans. Documentation on other reports of the same issue for your reference. - January 22, 2025 — Complaint 11637674: A 2022 Sanctuary owner reported repeated secondary alternator failures. - June 17, 2026 — Complaint 11744782: Another 2022 Sanctuary owner alleged improper grounding of the Thor-installed secondary alternator, repeated failures, and fire risk. - February 4, 2025: A 2024 Sanctuary owner reported two secondary alternator failures within nine months. The second failure allegedly shredded a belt and disabled engine cooling.

Thor company of Indiana is the after market uplifter of a Ford Transit 2022. The Sancuary is teh model. The red power wire that connects from the secodnary altrnator in the enginne area runs along the inside f the front right tire to the chassi house battery in the back o the VAN. The power wire is incorrectly routed and the tire rubs up againsit it and rubs against the wire casuing damage and saftey issue. All of the 2023 models appear t be involved from a small sampling of owners on a facebook THOR sancuary owners forum. Thor refuses to issue a recall and refuses to facilitate the wire being replaced. They instead try to get you to take the van to the dealership and have it spliced instead. I would imagine there are some people that do not even know o the safety issue.
