What it said before
Nothing has changed while we have been watching. We last read the wording of this campaign on 17 September 2026, and it matched the copy we already held.
That copy hashes to e8c6fd4136c685c7368a72406e21d437…, so if it is ever edited the change is provable rather than a matter of memory.
This is one of 145 notices in the record whose component field names fuel system, other. Across that group the median wait before owners were written to was 35 days.
Last checked . No change has been recorded in the wording.

The copy quoted above hashes to e8c6fd4136c685c7368a72406e21d437…. 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 25V440 · how the whole register is watched
447 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 Freightliner Cascadia, in all seven, is kept on that vehicle's own page, with the newest in each.
