What it says"Global Telematics Box Module (TBM) Firmware Over The Air (FOTA) Update 2023 - 2025 (JL) Jeep Wrangler 2023 - 2025 (JT) Jeep Gladiator This bulletin applies to vehicles built on or before May 05, 2025 (MDH 0505XX)… NHTSA’s full summary ↓

Jeep filed this with NHTSA as a service bulletin dated May 11, 2025, received May 14, 2025, about the electrical system. It names 6 model years (2023–2025). 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 communication
Built on or before 5 May 2025 “Built on or before May 05, 2025”

What 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.

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 database

Owners of the 6 model years this bulletin names have filed 1,533 complaints with NHTSA since 2015. 851 of them name Electrical System — 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.

On the 2024 Jeep Wrangler, the 64 owners who gave an odometer reading for Electrical System reported it at a median of 15,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Has Also stopped all the electrical with the engine driving down the road when my husband was returning from work, this is a safety issue please respond

Common questions

Source: NHTSA, 49 CFR 579.5

Is Jeep 08-155-25 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 08-155-25 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 08-155-25 cover?

The manufacturer filed it against 6 model years: 2025 Jeep Gladiator, 2024 Jeep Gladiator, 2023 Jeep Gladiator, 2025 Jeep Wrangler, 2024 Jeep Wrangler, 2023 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 5 May 2025 — the build date is on the certification label in the driver’s door jamb.
