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 communicationSome 2020-2023 Ford and Lincoln SYNC3 equipped vehicles may experience an inaccurate notification in the FordPass®/LincolnWay® app indicating Vehicle Has Entered Deep Sleep Mode. Vehicle Has Entered Deep Sleep Mode message is expected if the vehicle has not been started for 14 consecutive days, battery voltage is at/below 9.5 volts or the body control module (BCM) 12 volt battery state of charge (SoC) drops below 50%. If the vehicle is going into deep sleep due to one of these conditions, follow normal Workshop Manual (WSM) Section 414-01 procedure to correct the concern. If the vehicle is going into deep sleep outside these conditions, this may be due to the telematics control unit (TCU) software. To correct this condition, follow the Service Procedure to update the TCU to the latest software. For claiming, use causal part 14G229 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

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 54 model years this bulletin names have filed 11,324 complaints with NHTSA since 2015. 1,738 of them name 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 2021 Ford Bronco Sport, the 67 owners who gave an odometer reading for Electrical System reported it at a median of 41,426 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Check engine light came on at 24k miles. Alert on Ford Pass app said the engine wasn't heating up to operating temperature fast enough. Had a second Alert come up the next time I drove the car saying there was an electrical issue in the vehicle causing anti lock breaks and other important driver assistance features to not work including…
2021 Ford EcoSport · Electrical System · filed with NHTSA Dec 7, 2023 · ODI 11558901
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
Vehicle wouldn't start using push button start, several modules/components reported errors: traction control, parking break, steering, shifting. The vehicle drove fine less than 24 hours prior to 3/3/2024. Following a week at the dealership, Ford Motor Company and the Ford dealership determined the main wiring harness was the culprit.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52307 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 52307 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 52307 cover?
The manufacturer filed it against 66 model years across 2 brands (Ford and Lincoln): 2023 Ford Bronco Sport, 2022 Ford Bronco Sport, 2021 Ford Bronco Sport, 2022 Ford EcoSport, 2021 Ford EcoSport, 2020 Ford EcoSport and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
