The same recall in other countries
This campaign carries a manufacturer code that also appears in another country’s register, which means the same defect was recalled there too.
- Canada: Transport Canada recall 2026312, recorded 26 June 2026
Matched on F1035, the manufacturer’s own number for this campaign, which is the only field the registers share. Exact match, nothing paired on brand and date. The two dates are adjacent instruments rather than the same one, so a difference of a day or two means nothing.

The copy quoted above hashes to ba9ce6d61b2b2792dd270f78f2a991bc…. If the notice is reworded later, that fingerprint will not match, which is how a reader checks that the quotation was of the version we say it was.

The wording we hold for 26V408 · how the whole register is watched
83 days after this was filed with the regulator, the register still carries no date for the letter to owners. The sixty days 49 CFR 577.7 allows have passed. A blank there is a gap in the record, which is not the same as a gap in the post: where this maker stands on the sixty days.
This notice names one vehicle among several registers that have written about it. Every notice this site holds for the Thomas Built Buses Saf-T-Liner HDX2, in all seven, is kept on that vehicle's own page, with the newest in each.
