What it saysInspecting Cooling system for proper installation to prevent restrictions NHTSA’s full summary ↓
Volkswagen filed this with NHTSA as a service bulletin dated Feb 5, 2026, received Mar 3, 2026, about the engine. It names 5 model years (2023–2026). 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 5 model years this bulletin names have filed 568 complaints with NHTSA since 2015.
On long drives (1+ hour or more) my 2023 VW ID.4 Pro S (all electric) displays a "limited driving power" warning at random times, and the speed drops by half or more. This has happened on all long drives (5 separate days) and the car has been serviced by the dealer three times and they cannot find a solution.

Common questions
Source: NHTSA, 49 CFR 579.5Is Volkswagen V1923012072064_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 V1923012072064_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.

The manufacturer filed it against 5 model years: 2025 Volkswagen ID. Buzz, 2026 Volkswagen ID.4, 2025 Volkswagen ID.4, 2024 Volkswagen ID.4, 2023 Volkswagen ID.4. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
