What it said before
This campaign is in the register but not yet in the dated wording archive, so we cannot yet say whether its text has moved. It enters the archive on the next pass.
This is one of 1,836 notices in the record whose component field names electrical system. Across that group the median wait before owners were written to was 41 days.
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 2019670, recorded 23 December 2019 (3 years before the American filing)
Matched on 22523, 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.
