Volkswagen bulletin V9324012073298_4

What it saysRange reduction / battery cell replacement NHTSA’s full summary ↓

Volkswagen filed this with NHTSA as a service bulletin dated Sep 30, 2026, received Oct 6, 2026, about the electrical system. It names 3 model years (2021–2023). 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 database

Owners of the 3 model years this bulletin names have filed 940 complaints with NHTSA since 2015. 470 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 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.

On multiple occasions, my brand new ID.4 has shut down while driving giving various error messages relating to the electrical system and safety features--including with the electrical system generally, with the "12 Volt electrical system", with the auto assist braking, with lane assist, etc

My instrument cluster and infotainment system went black while driving. This means that I had no access to my speedometer, which I believe is a safety issue. Additionally, I had no access to my range estimate or any other vehicle information. No backup camera, no lane assist, etc

On Saturday, February 4, 2023. At approximately 7am. I entered the vehicle to warm the car. (It was a cold day). I tried to exit the vehicle, but I could not exit the driver's side door. It was not opening. I tried many times via the door handle and the key fob. Neither worked.

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 579.5

Is Volkswagen V9324012073298_4 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 V9324012073298_4 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 V9324012073298_4 cover?

The manufacturer filed it against 3 model years: 2023 Volkswagen ID.4, 2022 Volkswagen ID.4, 2021 Volkswagen ID.4. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
