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 889e2004e174d1357098b022579c52bc…, so if it is ever edited the change is provable rather than a matter of memory.
This is one of 93 notices in the record whose component field names vehicle speed control. Across that group the median wait before owners were written to was 37 days.
Last checked . No change has been recorded in the wording.
How to cite this record
Quoting the wording on this page means quoting a version, so the date belongs in the citation:
CarsMultiverse, recall 25V138, wording as read on 17 September 2026. https://carsmultiverse.com/recall/25v138/
The copy quoted above hashes to 889e2004e174d1357098b022579c52bc…. 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.
