What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2024 F-150 vehicles may set diagnostic trouble code (DTC) P0534:00 in the powertrain control module (PCM) when a diagnostic self-test is performed. This may be due to the PCM responding to large changes in ambient temperatures from warm to below freezing when the vehicle has less than 62 miles (100 km) and still in a rapid learn mode for the ambient air temperature logic. The rapid update to the temperature can result in the vehicle setting this DTC. DTC P0534:00 does not affect vehicle drivability and has no effect on vehicle operation. No additional diagnostics or service is required for this condition at this time. DTC P0534:00 is a background diagnostic code for service only and does not illuminate the malfunction indicator lamp (MIL), powertrain malfunction indicator (wrench), or provide any indication to the vehicle operator. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q2 2024. Replacement or reprogramming of the PCM will not resolve this condition. Monitor OASIS for additional informati

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 232 complaints with NHTSA since 2015. 67 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.
A Powertrain Malfunction/Reduced Power light showed up on my 2024 Ford F150 4x4 (9700 miles) and again and several other times including today. I immediately took it to Ford of Columbia in Columbia TN, and the diagnoses that there was an issue with the Gear Shift Lever Module (Part #RL3Z7210AD) and it was ordered.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52309 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 52309 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 52309 cover?
The manufacturer filed it against 1 model year: 2024 Ford F-150. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
