What owners reported
Source: NHTSA complaint databaseOwners of the 44 model years this bulletin names have filed 6,409 complaints with NHTSA since 2015. 727 of them name Service Brakes — 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 44 owners who gave an odometer reading for Service Brakes reported it at a median of 14,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The brake pedal failed and went to the floor; the vehicle would not brake. The service center identified the issue as a problem with the master cylinder. The vehicle had been serviced at an authorized service center every 10,000 miles. This incident occurred while driving and posed a threat to life and safety; the vehicle is a 2025 model

I do not feel safe with my Vehicle. I purchased new and at 16,550 Miles it needed new rear rotors and pads. Again at 38417 it needed new rotors and pads. I drive the car softly and am not heavy on the brakes. This seems to be a known issue and the dealership says I should be prepared to replace rotors and pads this frequently.

Common questions
Source: NHTSA, 49 CFR 579.5Is Volkswagen V4521012062957_5 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 V4521012062957_5 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.

The manufacturer filed it against 44 model years: 2023 Volkswagen Arteon, 2022 Volkswagen Arteon, 2021 Volkswagen Arteon, 2020 Volkswagen Arteon, 2019 Volkswagen Arteon, 2025 Volkswagen Atlas and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
