What owners reported
Source: NHTSA complaint databaseOwners of the 75 model years this bulletin names have filed 8,442 complaints with NHTSA since 2015. 2,154 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.
On the 2018 Volkswagen Atlas, the 66 owners who gave an odometer reading for Electrical System reported it at a median of 19,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
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.

Carnet in-car system doesn't work. Brought home the new 2019 Tiguan with only 5 miles on it and when I pushed the carnet buttons....nothing. Contacted the dealer and the service department took two days to try to fix it. I was told there was no fix. It's a software problem and VW must come up with a fix. Over 2 months later, still fix.

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 VOS-26-15 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 VOS-26-15 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 VOS-26-15 cover?
The manufacturer filed it against 75 model years: 2023 Volkswagen Arteon, 2022 Volkswagen Arteon, 2021 Volkswagen Arteon, 2020 Volkswagen Arteon, 2019 Volkswagen Arteon, 2026 Volkswagen Atlas and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
