Ram filed this with NHTSA as a service bulletin dated Dec 4, 2024, received Dec 10, 2024, about the power train. It names 1 model year (2024).

Quoting the number at a service desk can save a diagnosis.

Read by machine from the document NHTSA serves (2 pages), read Sep 30, 2026. A part number is shown only where it matches Ram’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.

NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
Came to a stop sign, waited for traffic to clear to turn left as I floored it started moving and then all of a sudden loss acceleration and notice rpm ramped up to 7k. As in was just coasting I notice only my rpm would go up but the truck wouldn’t move. Lucky I coasted to the side of road and shifted to park.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ram 18-085-24 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 18-085-24 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 18-085-24 cover?
The manufacturer filed it against 1 model year: 2024 Ram 1500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
