What it saysThe Customer May Complain About a Popping Noise, Grinding Noise, or an Intermittent No Reverse or Forward Transmission Engagement. NHTSA’s full summary ↓
Stellantis filed this with NHTSA as a service bulletin dated Sep 30, 2026, received Oct 7, 2026, about the power train. It names 62 model years across Jeep, Ram, Dodge and Chrysler (2018–2027). 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 62 model years this bulletin names have filed 17,013 complaints with NHTSA since 2015. 2,001 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 2018 Jeep Wrangler, the 86 owners who gave an odometer reading for Power Train reported it at a median of 30,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Common questions
Source: NHTSA, 49 CFR 579.5Is Stellantis S2621000004 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 S2621000004 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 S2621000004 cover?
The manufacturer filed it against 62 model years across 4 brands (Jeep, Ram, Dodge and Chrysler): 2023 Chrysler 300, 2022 Chrysler 300, 2021 Chrysler 300, 2020 Chrysler 300, 2019 Chrysler 300, 2018 Chrysler 300 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
