Ford bulletin TSB 24-2046
What it saysThis article supersedes TSB 23-2350 to update the Issue statement and the Service Procedure. NHTSA’s full summary ↓
Ford filed this with NHTSA as a service bulletin dated Feb 23, 2024, received Mar 7, 2024, about the electrical system. It names 21 model years across Ford and Lincoln (2017–2023). 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.

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.
This article supersedes TSB 23-2350 to update the Issue statement and the Service Procedure. Some 2017-2020 F-150, 2018-2021 Expedition/Navigator/Mustang, 2019-2023 Ranger vehicles equipped with a 10R80 transmission may exhibit a harsh/delayed engagement and/or harsh/delayed shift, an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module (PCM) or transmission control module (TCM). This may be due to the transmission solenoid ID strategy, sticking valves in the main control valve body and/or axial movement of the CDF clutch cylinder (7H351) sleeve.

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 21 model years this bulletin names have filed 8,767 complaints with NHTSA since 2015. 4,662 of them name Power Train, Electrical System — 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 Ford F-150, the 334 owners who gave an odometer reading for Power Train reported it at a median of 60,350 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The collision warning doesn't warn sometimes. Nothing goes off when Im approaching and or have slammed on my breaks to avoid a collision. Sometimes it goes off at a great distance when it doesn't make sense to go off. I just bought the car used and have noticed this a lot. Also sometimes lane departure corrects and sometimes it doesn't.
2020 Lincoln Navigator · Electrical System · filed with NHTSA Sep 2, 2025 · ODI 11684616
The contact owns a 2023 Ford Ranger. The contact stated while driving at an undisclosed speed, the vehicle inadvertently decelerated to 40 MPH, and the vehicle then shifted into 4WD-Low independently. As a result of the failure, the vehicle dramatically decelerated and skidded to a complete stop. The 4WD warning light was illuminated.
2023 Ford Ranger · Power Train · filed with NHTSA Mar 28, 2025 · ODI 11651300
Ford is aware of a design defect that causes the vct system to wear out within a short amount of time in brand new expeditions. When the vct system wears out, the vehicle immediately transitions into "limp mode" , which causes the vehicle to immediately (unsafely) decelerate to a speed of 15mph (or less on hills), creating dangerous…

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 24-2046 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 24-2046 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 24-2046 cover?
The manufacturer filed it against 21 model years across 2 brands (Ford and Lincoln): 2021 Ford Expedition, 2020 Ford Expedition, 2019 Ford Expedition, 2018 Ford Expedition, 2020 Ford F-150, 2019 Ford F-150 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
