What it says"FCA CARIBBEAN WARRANTY BULLETIN ID-24-16 Addition of Rear Axle / Differential Assembly for 2019 - 2024 RAM 3500 Cab Chassis (DD) to the Powertrain Service Center (PTSC) Pre-Authorization Program" NHTSA’s full summary ↓

Ram filed this with NHTSA as a warranty extension dated Sep 11, 2024, received Sep 17, 2024, about the power train. It names 6 model years (2019–2024). A warranty extension is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

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 569 complaints with NHTSA since 2015. 173 of them name Power Train — 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 2022 Ram 3500, the 13 owners who gave an odometer reading for Power Train reported it at a median of 16,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

The transmission lost gears 1 through 4 on the freeway in traffic. We were going approximately 25mph in the fast lane when it happened. We were lucky enough to have enough speed to make it to the shoulder, but were left stranded on the shoulder. Truck is at dealer needing a transmission replacement that can't be ordered at this time

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 Ram 100494 a recall?

No. A warranty extension 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 100494 repair free?

A warranty extension is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.

Which vehicles does 100494 cover?

The manufacturer filed it against 6 model years: 2024 Ram 3500, 2023 Ram 3500, 2022 Ram 3500, 2021 Ram 3500, 2020 Ram 3500, 2019 Ram 3500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
