Read by machine from the document NHTSA serves (13 pages), read Sep 29, 2026. A part number is shown only where it matches Volkswagen’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 49 model years this bulletin names have filed 6,418 complaints with NHTSA since 2015. 872 of them name Forward Collision Avoidance — 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 2019 Volkswagen Atlas, the 16 owners who gave an odometer reading for Forward Collision Avoidance reported it at a median of 15,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The vehicle’s Forward Collision Avoidance system (Front Assist) and Automatic Emergency Braking (AEB) intermittently malfunction while driving. On at least three separate occasions during clear, dry weather with clean sensors, the AEB system engaged full hydraulic braking unexpectedly with no obstacles ahead—once while utilizing Adaptive…

2021 Volkswagen Jetta · Forward Collision Avoidance · filed with NHTSA Mar 12, 2023 · ODI 11511441
This defect causes multiple, non-periodic, but repeated, "Travel assist unavailable" audible and visual alarms at seemingly unrelated and unpredictable times while driving. My favorite times are when you start making a turn after coming to a full stop and it alarms, asking you to take your eyes off the road and look at the dash.

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 V4521012062957_7 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_7 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 V4521012062957_7 cover?
The manufacturer filed it against 49 model years: 2023 Volkswagen Arteon, 2022 Volkswagen Arteon, 2021 Volkswagen Arteon, 2020 Volkswagen Arteon, 2026 Volkswagen Atlas, 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.
