Stellantis bulletin 111406

Stellantis filed this with NHTSA as a service bulletin dated Apr 8, 2026, received Apr 22, 2026, about the engine. It names 24 model years across Jeep, Ram, Dodge and Chrysler (2024–2026). 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.

One page for every brand it was filed under. Each brand’s bulletins: Jeep · Ram · Dodge · Chrysler.

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 24 model years this bulletin names have filed 2,229 complaints with NHTSA since 2015. 919 of them name Engine — 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 57 owners who gave an odometer reading for Engine 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.

The contact owns a 2024 Ram 1500.

Additionally, the hazards lights failed to engage as needed.

2024 Ram 1500 · Engine · filed with NHTSA Nov 6, 2024

I was driving the Jeep on Route 35 in NJ when all of a sudden, the car lost power, jerked forward thrusting be towards the windshield. The "D" on the gear shift started blinking and the check engine light went on. The dashboard message indicated something along the lines that I had to put the car in parking "P".

2025 Jeep Wrangler · Engine · filed with NHTSA Oct 21, 2025

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 579.5

Is Stellantis 111406 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 111406 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.

Which vehicles does 111406 cover?

The manufacturer filed it against 24 model years across 4 brands (Jeep, Ram, Dodge and Chrysler): 2026 Chrysler Pacifica, 2025 Chrysler Pacifica, 2024 Chrysler Pacifica, 2026 Chrysler Voyager, 2025 Chrysler Voyager, 2024 Chrysler Voyager and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
