Volkswagen filed this with NHTSA as a service bulletin dated Aug 24, 2023, received Sep 1, 2023, about the seat belts. 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 1,714 complaints with NHTSA since 2015. 988 of them name Electrical System, Engine — 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 27 owners who gave an odometer reading for Electrical System reported it at a median of 12,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

2022 Volkswagen Tiguan · Electrical System · filed with NHTSA Sep 16, 2022
After noticing an oil leak and blue smoke in my 23 VW atlas, I took it to my local dealership in Tupelo, MS. I realized there was an open recall for the PCV Valve / Oil separator under code 10LP. However, the bad PCV valve also caused the timing chain cover to go bad. The dealership called me back and said VW would not cover this issue.
2023 Volkswagen Atlas · Engine · filed with NHTSA Jul 20, 2026
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.

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 VIN4APIN20230824 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 VIN4APIN20230824 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.
Which vehicles does VIN4APIN20230824 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.
