NHTSA filing tells ID.4 owners to cap the charge at 80%

The instruction in Volkswagen's newest ID.4 recall is aimed at the charge, not the parking brake. Owners of certain 2023 through 2026 models are being told to leave the top of the battery unused until the company has a repair. The filing does not tell them to stop driving.

National Highway Traffic Safety Administration campaign 26V630, received on 30 September 2026, covers certain Volkswagen ID.4 vehicles from those four model years. The summary is short: the high-voltage battery may fail and lead to a vehicle fire, and a fire raises the risk of injury. Volkswagen's number for the campaign is 93EX. The vehicle identification numbers involved became searchable on NHTSA.gov on 6 October 2026.

The remedy language is an interim rule. "Owners are advised to only charge their vehicles to a maximum of 80% battery capacity until the repair has been completed." NHTSA says the repair itself is still under development. Interim letters are expected to be mailed on 27 November 2026, with further letters once a remedy exists. Until those letters, the public instruction is the 80 percent ceiling, and Volkswagen customer service is listed at 1-800-893-5298.

Two fields on the same record are easy to miss. The campaign is not marked as a park-it order or a park-outside order, and it is not marked as an over-the-air update. The filing does not say the car will refuse a charge past 80 percent by itself. As written, the owner has to keep the session at or below that line.

InsideEVs reporter Nico DeMattia, in a piece carried by inkl, put a population on the campaign: 22,524 ID.4s from the 2023 through 2026 model years. The same account says Volkswagen estimates that 0.1 percent of those cars are actually affected, and that the company says incidents can happen above that state of charge. The percentage is an estimate of how many packs fail, not a reason to ignore the ceiling. The advice applies to the recalled group while the repair is unfinished.

NHTSA's public summary and the InsideEVs account agree on the 80 percent step. They do not carry the same detail. The summary served by NHTSA's vehicle-recall API does not include the 22,524 figure or the 0.1 percent estimate. Those come from DeMattia's reading of the recall documents. NHTSA's summary does not name a cause. A separate campaign, 26V030, filed on 21 January 2026, covers a high-voltage battery that may overheat in certain 2023-2025 ID.4s. That is an earlier filing, not this remedy.

Owners can look up the car now. NHTSA says the VINs have been searchable since 6 October, so the useful check is whether this vehicle is inside 26V630, then whether charging is being stopped at 80 percent. A session left to run to full, because that is how the car was last set, is the mistake the filing is trying to prevent. There is still no repair. The ceiling is the safety plan on the page, and it stays there until Volkswagen says the remedy is ready.
