Volkswagen Group of America is recalling 22,524 model year 2023–2026 ID.4 electric vehicles because the high-voltage battery may experience thermal propagation and catch fire. Until a remedy is available, owners are advised to limit charging to 80%. In its Part 573 Safety Recall Report to NHTSA, the company states that the root cause is unknown. However, certain charging profiles combined with a state of charge above 80% may trigger the failure. Volkswagen estimates that 0.1% of the recalled vehicles have the defect.
Highlights
- 22,524 vehicles: 2023–2026 ID.4 models produced from January 1, 2023, through February 1, 2025.
- 80% charging limit: Owners are advised not to charge above 80% until the remedy is performed.
- 22 claims: Volkswagen identified 22 U.S. claims from January 18, 2024, through August 7, 2026.
- November 27, 2026: Interim owner notification letters are expected to be mailed.
What Causes the ID.4 Battery Fire Risk?
According to the filing, in certain high-voltage batteries within the recall population, specific charging profiles combined with a state of charge over 80% may trigger thermal propagation. If thermal propagation occurs, it may result in a vehicle fire.
The battery supplier is SK Battery America Inc. of Commerce, Georgia. The recall covers three high-voltage battery part numbers:
- 11K.915.599.A
- 11K.915.599.D
- 11K.915.592.D
Volkswagen determined the recall population from vehicle assembly records, battery traceability information, supplier production records and available vehicle charging data. Vehicles outside the population either contain cells produced outside the suspect range or have recent and complete data showing charging usage below the defined threshold, the company reports.
How Volkswagen Identified the Defect
On June 17, 2026, during an ongoing review of high-voltage battery thermal events in the field, preliminary data pointed to a potential influence from specific isolation-resistance values and DC-charging ratios. The Volkswagen Product Safety Committee then ordered a field study of complete battery systems from vehicles not included in its previous HV battery recall campaigns.
The committee reviewed the study results on September 21, 2026. It requested additional information from the cell supplier on production measures and a potential clean date. It also ordered analyses of vehicle charging behavior and of what an interim 80% state-of-charge cap would require.
On September 23, 2026, the committee decided to conduct a voluntary safety recall. The root cause remains unknown, but the decision was based on the field situation and the potential safety consequences of a high-voltage battery failure.
What Should ID.4 Owners Do?
The final remedy is still under development. As an interim risk-reduction measure, all affected owners will receive warning stickers to place on the vehicle reminding drivers not to charge the battery above 80%. Depending on vehicle configuration and online connectivity, some vehicles may also be configured to cap the battery’s maximum state of charge at 80%.
The filing does not issue a Park Outside or Do Not Drive advisory. Volkswagen will not offer a reimbursement plan because the affected vehicles are still within the New Vehicle Limited Warranty period.
Recall Schedule
Dealer notification was planned for October 6, 2026, the same day affected VINs became searchable on NHTSA.gov. Interim owner letters explaining the safety risk are expected to be mailed November 27, 2026. Additional letters will follow once the remedy is available, under a phased recall.
Volkswagen’s number for this recall is 93EX, and the NHTSA recall number is 26V-630. Owners may contact Volkswagen customer service at 1-800-893-5298.
