What owners reported
Source: NHTSA complaint databaseOwners of the 12 model years this bulletin names have filed 221 complaints with NHTSA since 2015. 51 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.
My car randomly has a battery charging fault. An alert stating “stop safely 12V battery critical charging fault” will just pop up while driving and then put the vehicle in turtle mode. This is an intermittent fault and is likely a false indication. This could cause an accident because it causes the car to slow down.
2025 Volvo XC40 · Electrical System · filed with NHTSA Jan 27, 2026 · ODI 11713785
There are 2 very serious safety issues that are extremely dangerous with this car. #1 - The Automatic Intervention Rear Brake Auto Brake engages for no reason when there is nothing behind the car. It happens when I am backing up very slowly. It throws me forward and then thrusts me back into the headrest.

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 Volvo 37376 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 37376 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 37376 cover?
The manufacturer filed it against 13 model years: 2024 Volvo C40, 2023 Volvo C40, 2022 Volvo C40, 2026 Volvo EC40, 2025 Volvo EC40, 2025 Volvo EX40 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
