Jeep filed this with NHTSA as a service bulletin dated May 21, 2026, received Mar 25, 2026, about the forward collision avoidance — 3 documents under this number: 08-114-26 (2 filings) 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.

Read by machine from the document NHTSA serves (3 pages), read Sep 29, 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.

1. Deceptive Failure of Equipment: The "We Owe" document is a binding contract proving the dealer was required to deliver a functional towing infrastructure. By installing a physical 7-way plug housing but leaving the internal wiring dead, Dewey CDJR did not just break a contract—they created an undeclared equipment hazard. 2.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep 08-114-26 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 08-114-26 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 08-114-26 REV. A cover?
The manufacturer filed it against 1 model year: 2026 Jeep Wrangler. 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 17 Mar 2026 — the build date is on the certification label in the driver’s door jamb.
