I pulled my 2022 Maverick into my parking spot at work and everything went dead. I had to use my key to open my tailgate. The tow service jumped the battery and it started, however, when they went to take it off the tow truck at the Ford dealership, it had to be jump started again. I was told the battery was bad and they changed it.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 54621 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 54621 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 54621 cover?
The manufacturer filed it against 4 model years: 2025 Ford Maverick, 2024 Ford Maverick, 2023 Ford Maverick, 2022 Ford Maverick. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
