Volkswagen filed this with NHTSA as a service bulletin dated Jul 31, 2023, received Aug 4, 2023, about the electrical system. It names 9 model years (2022–2023). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

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 9 model years this bulletin names have filed 1,760 complaints with NHTSA since 2015. 602 of them name Electrical System, Structure, Exterior Lighting — 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 2023 Volkswagen ID.4, the 28 owners who gave an odometer reading for Electrical System reported it at a median of 12,800 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 simply shuts off with no warning or reason. I should NOT have to explain to anybody how this is a safety hazard to the driver and others around the vehicle. It shuts down while in a car wash and the vehicle is in Neutral. Thus, I have to brake, place the trans in Park then manually restart. The same happens at Stop Lights.

Common questions
Source: NHTSA, 49 CFR 579.5Is Volkswagen VIN4APIN20230731 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 VIN4APIN20230731 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 VIN4APIN20230731 cover?
The manufacturer filed it against 9 model years: 2023 Volkswagen Atlas, 2022 Volkswagen Atlas, 2023 Volkswagen ID.4, 2023 Volkswagen Jetta, 2022 Volkswagen Jetta, 2023 Volkswagen Taos and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
