What it saysSome 2020-2024 Escape and Corsair Vehicle equipped with the 8F35 or the HF45 transmission may exhibit a click or ting noise during acceleration from a stop, or in some cases during the end of a stop event. NHTSA’s full summary ↓
Ford filed this with NHTSA as a service bulletin dated Jun 3, 2024, about the power train. It names 10 model years across Ford and Lincoln (2020–2024). 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 the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.
Some 2020-2024 Escape and Corsair Vehicle equipped with the 8F35 or the HF45 transmission may exhibit a click or ting noise during acceleration from a stop, or in some cases during the end of a stop event. This may be due to the front half shaft sticking to the wheel bearing surface. To correct this condition, perform the Service Procedure below to lubricate the halfshaft and wheel bearing hub assembly mating surface.

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 10 model years this bulletin names have filed 3,237 complaints with NHTSA since 2015. 419 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.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 24-2139 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 24-2139 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 24-2139 cover?
The manufacturer filed it against 10 model years across 2 brands (Ford and Lincoln): 2024 Ford Escape, 2023 Ford Escape, 2022 Ford Escape, 2021 Ford Escape, 2020 Ford Escape, 2024 Lincoln Corsair and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
