Ford bulletin TSB 24-2185
What it saysThis article supersedes TSB 23-2335 to update the TSB title, vehicles affected and parts list. NHTSA’s full summary ↓
Ford filed this with NHTSA as a service bulletin dated Jun 7, 2024, received Jun 12, 2024, about the power train. It names 9 model years across Ford and Lincoln (2020–2023). 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 (12 pages), read Sep 30, 2026. A part number is shown only where it matches Ford’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 4,205 complaints with NHTSA since 2015. 681 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 2020 Ford Escape, the 78 owners who gave an odometer reading for Power Train reported it at a median of 46,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Transmission realized a catastrophic and destructive failure. The vehicle immediately lost power and speed. Scattering debris and transmission fluid on the highway. Causing a safety concern for me and other drivers. Confirmed by a dealer. Inspected by the dealer. I experienced irregular transmission shifts and shuttering at times.
2021 Lincoln Corsair · Power Train · filed with NHTSA Nov 11, 2025 · ODI 11698723
In three occasions the automatic transmission has stopped working, operating under normal city driving conditions. Turning the car off and on again, it has worked properly. The car has less than 4000 miles. I took it to the Ford repair shop and there is a defect in the hybrid transmission, and it will take 4-6 weeks to be solved.

The wrench icon which refers to the Powertrain system keeps coming on. I received a message from the Ford pass system that there was (Fault) in the Powertrain system. That power was reduced. Further it said to see a dealer right away. All of the Ford Dealers in my area are all booked up

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 Ford TSB 24-2185 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 TSB 24-2185 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 TSB 24-2185 cover?
The manufacturer filed it against 9 model years across 2 brands (Ford and Lincoln): 2023 Ford Bronco Sport, 2022 Ford Bronco Sport, 2021 Ford Bronco Sport, 2022 Ford Escape, 2021 Ford Escape, 2020 Ford Escape 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: 2021-2023 Bronco Sport: built on or before 30 Nov 2022; 2021-2022 Bronco Sport: built on or before 28 Feb 2022; 2020-2022 Escape/Corsair: built on or before 30 Apr 2022 — the build date is on the certification label in the driver’s door jamb.
