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 1c99106a8d772e5328c65cd6492fbcd6…, so if it is ever edited the change is provable rather than a matter of memory.
This is one of 175 notices in the record whose component field names parking brake. Across that group the median wait before owners were written to was 49 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 2025351, recorded 25 June 2025 (within a week of the American filing)
Matched on N252503010, 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.
