What owners reported
Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 101 complaints with NHTSA since 2015. 49 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.
To start, have requested the vehicle paperwork many times and the dealership has failed to give me a copy. The real problem started when i took my EV to get checked as the battery was not lasting long, they said it was normal, took it again as it stopped charging on type 1 and 2 chargers, they now said it was the Onboard charging module.

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 Volkswagen 5.6 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 5.6 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. Every Volkswagen warranty extension on file lists the ones Volkswagen has filed.
Which vehicles does 5.6 cover?
The manufacturer filed it against 4 model years: 2025 Volkswagen ID. Buzz, 2026 Volkswagen ID.4, 2025 Volkswagen ID.4, 2024 Volkswagen ID.4. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
