Ford filed this with NHTSA as a service bulletin dated Jun 11, 2024, about the power train. It names 8 model years across Ford and Lincoln (2021–2024). 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 2021-2024 F-150 and 2023-2024 Expedition/Navigator vehicles equipped with a 3.5L EcoBoost engine may exhibit a rattle/scraping noise from the bellhousing area on start-up. This may be due to the torque converter studs contacting the engine-to-transmission spacer plate (separator plate). To correct this condition, remove the transmission and flexplate and inspect the engine-to-transmission spacer plate and torque converter studs for wear/damage. If wear/damage is found, replace the engine-to-transmission spacer plate. Refer to Workshop Manual (WSM) Section 303-01 Engine - 3.5L EcoBoost (BM), Removal and Installation, Crankshaft Rear Seal. When reinstalling the starter motor, make sure the starter is flush with the engine-to-transmission spacer plate prior to tightening the studbolts. Failure to do so may result in damaging the newly installed engine-to-transmission spacer plate.

What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 3,041 complaints with NHTSA since 2015. 969 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 Ford F-150, the 88 owners who gave an odometer reading for Power Train reported it at a median of 58,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Passenger side rear axle retention bolt sheared off. Discovered during routine maintenance / tire rotation. Unknown how safety was at risk -- dealer told me once discovered that the vehicle would be repaired under warranty, and they could do in 24 hours, so no discussion about unsafe to drive as others have reported they were told.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52610 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 SSM 52610 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 SSM 52610 cover?
The manufacturer filed it against 8 model years across 2 brands (Ford and Lincoln): 2024 Ford Expedition, 2023 Ford Expedition, 2024 Ford F-150, 2023 Ford F-150, 2022 Ford F-150, 2021 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.
