What it said before
Nothing has changed while we have been watching. We last read the wording of this campaign on 10 September 2026, and it matched the copy we already held.
That copy hashes to 13b10c7f74b0ac16dd693043d37f573b…, so if it is ever edited the change is provable rather than a matter of memory.
This is one of 815 notices in the record whose component field names power train. Across that group the median wait before owners were written to was 42 days.
Last checked . No change has been recorded in the wording.
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 2024637, recorded 24 October 2024 (within a week of the American filing)
- European Union: Safety Gate alert SR/01871/26, published 26 June 2026, raised by Germany (the Commission’s own page) (20 months after the American filing)
Matched on N242454440, 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 13b10c7f74b0ac16dd693043d37f573b…. 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.
