Jeep filed this with NHTSA as a service bulletin dated Sep 11, 2026, received Apr 29, 2026, about the electrical system — 2 documents under this number: 08-178-26 and 1 more. It names 1 model year (2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Flash: Power Liftgate Module (PLGM) Update Customers may comment on one or more of the following: ● The power liftgate chime remains active continuously and does not stop after the liftgate is closed or after an ignition cycle. ● The vehicle will not start due to a discharged battery. NOTE: Battery discharge caused by a continuously active liftgate chime or liftgate remaining open for an extended period. The following PLGM software enhancements are available with this software release: ● New Diagnostic Trouble Codes (DTCs) have been added to the PLGM to report out-of-range ambient temperature and the PLGM being left in plant mode. This bulletin involves reprogramming the PLGM with the latest software.

Read by machine from the document NHTSA serves (2 pages), read Oct 5, 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. Listings and prices on eBay Motors are the seller’s.

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
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 9 complaints with NHTSA since 2015. 2 of them name Electrical System, Structure — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
I was driving the vehicle in heavy traffic, at the speed of 1-3 mph, then stopped at a stoplight, when the hood latch spontaneously disengaged, allowing the hood to pop open. There was seemingly no reason this should have happened.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep 08-178-26 REV. A a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 08-178-26 REV. A repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Stellantis warranty extension on file lists the ones Stellantis has filed.
Which vehicles does 08-178-26 REV. A cover?
The manufacturer filed it against 1 model year: 2026 Jeep Cherokee. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built on or before 23 Jul 2026 — the build date is on the certification label in the driver’s door jamb.
