Jeep filed this with NHTSA as a service bulletin dated Jun 18, 2026, received May 20, 2026, about the power train — 2 documents under this number: 21-041-26 REV. A and 1 more. It names 9 model years (2021–2025). 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.

Read by machine from the document NHTSA serves (2 pages), read Sep 29, 2026. A part number is shown only where it matches Jeep’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.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 databaseOwners of the 9 model years this bulletin names have filed 4,219 complaints with NHTSA since 2015. 588 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 2021 Jeep Wrangler, the 17 owners who gave an odometer reading for Power Train 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.
Svc 4wd light went on in the car after start-up, and i tried to reverse from my parking spot with the wheel turned and it felt like the emergency brakes were on. I stopped to check and they were not. i tried to reverse again and the car starts making a grinding noise and jerking motion as it pulls out slowly.
2022 Jeep Wrangler · Power Train · filed with NHTSA Oct 27, 2022
On 10/10/25, my 2025 Jeep received an over-the-air (OTA) software update intended for the Uconnect infotainment system. Following the update, the vehicle experienced a complete powertrain failure. It became undrivable, shut off entirely, and refused to shift out of park.
2025 Jeep Wrangler · Power Train · filed with NHTSA Oct 14, 2025
Only 500 miles on vehicle, went off-roading for the first time and within a short time after climbing a steep hill, smoke came from under vehicle and clutch went to floor and stayed. Turned Jeep off, pumped clutch which seemed fine but smoke continued for a minute.
2021 Jeep Wrangler · Power Train · filed with NHTSA Feb 14, 2021
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 Jeep 21-041-26 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 21-041-26 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 21-041-26 cover?
The manufacturer filed it against 9 model years: 2025 Jeep Grand Cherokee, 2024 Jeep Grand Cherokee, 2023 Jeep Grand Cherokee, 2022 Jeep Grand Cherokee, 2025 Jeep Wrangler, 2024 Jeep Wrangler and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built on or before 19 Mar 2025; built on or before 8 Apr 2025 — the build date is on the certification label in the driver’s door jamb.
