What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2023-2024 Escape/Corsair vehicles equipped with a 1.5L or 2.0L EcoBoost engine, 2024 Mustang vehicles equipped with a 2.3L EcoBoost engine, and 2024 Nautilus vehicles may exhibit an engine misfire condition with diagnostic trouble codes (DTC) P0301, P0302, P0303 and/or P0304 set in the powertrain control module (PCM). If the codes are stored in the PCM, remove and inspect the condition of all the spark plugs. If all spark plugs are found to be free of damage, replacement of the spark plugs is not necessary. Refer to the Workshop Manual and perform normal diagnostics. If any spark plugs appear to be damaged, use a borescope to inspect the condition of the cylinder walls. If the cylinder walls are scored/scraped/damaged, replace the long block engine assembly (6006) to resolve this condition. If the cylinder walls are not scored/scraped/damaged, replace the damaged spark plug(s) and advise the customer that engineering is investigating this issue. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available.

What owners reported
Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 383 complaints with NHTSA since 2015. 59 of them name Engine — 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.
In Lincoln's own words the lithium batteries are flawed and can cause a short circuit which can lead to a fire. This could lead to grave danger to life. I keep my car in my garage which could lead to a house fire and harm to my family. Their original temporary fix was to set the charging system to stop at 80%.
2024 Lincoln Corsair · Engine · filed with NHTSA Sep 9, 2026
On May 10 a lighted wrench appeared on the instrument panel. The car felt as if I was loosing power. May 12 I got in the car, the wrench and check engine lights were both on. Called the dealer service department. They told me the car is not safe to drive as it cannot accelerator and will go into "limp mode".

2023 Ford Escape · Engine · filed with NHTSA Nov 26, 2024
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 SSM 52630 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 52630 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 52630 cover?
The manufacturer filed it against 6 model years across 2 brands (Ford and Lincoln): 2024 Ford Escape, 2023 Ford Escape, 2024 Ford Mustang, 2024 Lincoln Corsair, 2023 Lincoln Corsair, 2024 Lincoln Nautilus. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
