Ram filed this with NHTSA as a service bulletin dated Oct 21, 2024, received Oct 23, 2024, about the power train. It names 2 model years (2023–2024). 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 owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 283 complaints with NHTSA since 2015. 44 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.
The contact owns a 2023 Ram 1500. The contact stated that on three separate occasions, while driving at various speeds, the vehicle downshifted to the first gear inadvertently. The vehicle was steered to the side of the road and restarted. The vehicle was taken to a dealer however, the failure could not be replicated.

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.

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 579.5Is Ram S2403000006 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 S2403000006 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 S2403000006 cover?
The manufacturer filed it against 2 model years: 2024 Ram 1500, 2023 Ram 1500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
