Volkswagen recalls 22,524 ID.4s over battery fire risk and tells owners to cap charging at 80%

Volkswagen is recalling 22,524 ID.4 electric crossovers in the United States over a potential high-voltage battery fire risk, and it is asking owners to limit charging to 80% until a permanent fix is available. The recall covers 2023 to 2026 ID.4s built between January 1, 2023 and February 1, 2025, according to Volkswagen's Part 573 safety recall report filed with NHTSA. The affected batteries were supplied by SK Battery America, which is based in Commerce, Georgia. Volkswagen's internal number for the campaign is 93EX, and NHTSA lists it as recall 26V630.

The unusual part is that Volkswagen does not know what is causing the problem. Its recall report states that the root cause is unknown, but that in certain high-voltage batteries within the affected population, certain charging profiles combined with a state of charge over 80% may trigger thermal propagation, a process where heat from a failing cell spreads to neighboring cells and can result in a vehicle fire. Because the cause is unidentified, the remedy is still under development. A Volkswagen dealer notice dated October 6 put it bluntly: repair not yet available.

The recall population is narrow by design. Volkswagen estimates that only 0.1% of the recalled vehicles actually carry the defect, which works out to roughly two dozen cars out of the 22,524. The automaker built the list from assembly records, battery traceability data, supplier production records and available charging data, excluding ID.4s whose cells were produced outside the suspect range or whose recent charging data fell below a defined threshold that the report does not disclose. The dealer notice also counts a further 5,633 ID.4s from the 2023 to 2025 model years in Canada.

The investigation moved quickly once it started. On June 17, 2026, while reviewing battery thermal events in the field, Volkswagen saw preliminary data pointing to a possible link between thermal events, specific isolation-resistance values and DC charging ratios, and its Product Safety Committee ordered a field study of complete battery systems from vehicles not covered by earlier battery recalls. The committee reviewed the results on September 21, asked the cell supplier about its production measures and a potential clean date, and decided on September 23 to recall the vehicles even without a root cause. Volkswagen cites 22 claims from US customers between January 18, 2024 and August 7, 2026, though a separate summary of the NHTSA notice puts the figure at 23 claims over the same window.

In the meantime, owners get interim protections. Every affected owner will receive a warning sticker reminding them not to charge above 80%, and depending on vehicle configuration and online connectivity, some ID.4s may have their maximum state of charge capped at 80% in software. Interim notification letters are expected to mail on November 27, 2026, with follow-up letters once a remedy exists. VINs covered by the recall have been searchable on NHTSA.gov since October 6, and owners with questions can call Volkswagen at 800-893-5298. No reimbursement plan is offered because the affected vehicles remain within the new vehicle limited warranty period.

This is not an isolated event. According to a detailed review of NHTSA filings, this is the fourth ID.4 traction-battery recall Volkswagen has filed since December 2025, and all four name SK Battery America as the supplier with the same three battery part numbers. Recall 25V836, filed December 3, 2025, covered 629 vehicles with misaligned electrodes and a module replacement fix. Recall 26V028, filed January 21, 2026, covered 670 vehicles with a second shifted-electrode condition. Recall 26V030, filed the same day, covered 43,881 vehicles responding to self-discharge deviations with a battery health check and software. The earlier 26V028 campaign also told owners to set an 80% charge limit, avoid Level 3 DC chargers and park outdoors after charging.

For context, EV battery fires remain statistically rare. An EV FireSafe report verified 511 EV battery thermal runaway incidents worldwide from 2010 to June 2024, which one outlet estimated at roughly a 0.0013% chance of an EV fire, and about 15% of incidents in that report's most recent 12-month period occurred while charging. Still, the pattern across four recalls tied to one supplier, with the newest one lacking a known cause, is worth watching. The claim window in the new report opens on January 18, 2024, the same date an earlier recall's chronology gives for its first thermal event, a vehicle charging at a Level 3 DC charger in Illinois, which suggests the investigations may be connected.
