What the bulletin says

What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 1,148 complaints with NHTSA since 2015. 622 of them name Electrical System, 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.
On the 2022 Ford Maverick, the 28 owners who gave an odometer reading for Electrical System reported it at a median of 36,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
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.

I started the Car and it made loud boom boom sounds like as if I was at a loud concert for about 10 seconds. That stopped but then loud static or electrical sound continued even after car was turned off. Re started and the sound continued. The initial sound shook me and wife. Where wife refuses to get back in.

The plastic cooling system overflow expansion tank sign is stress cracking in the inlet tubing at approximately 8K miles. It has gotten worse with my odometer at 12K now. I have not contacted Ford regarding a warranty replacement because they would just replace it with the same defective part.

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 55157 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 55157 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 55157 cover?
The manufacturer filed it against 3 model years: 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.
