Read by machine from the document NHTSA serves (8 pages), read Sep 30, 2026. A part number is shown only where it matches Jeep’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported

NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2018 Jeep Wrangler, the 88 owners who gave an odometer reading for Electrical System reported it at a median of 18,570 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
