COMPLAINT ALLEGATION SUMMARY:
The lawsuit, filed in the United States District Court for the District of New Jersey, is captioned Chen v. Volkswagen Aktiengesellschaft, et al., No. 2:26-cv-05409 (D.N.J.). The complaint is filed on behalf of a class of all persons or entities in the United States who purchased, leased, or own model years 2023-2025 Volkswagen ID.4s designed, manufactured, marketed, distributed, sold, leased, warranted, and/or serviced by VW.

Specifically, the complaint alleges that 2023-2025 Volkswagen ID.4s, manufactured and sold by VW, have been built with defective high-voltage (“HV”) batteries that are susceptible to misaligned electrodes that can lead to thermal events and fires (the “Battery Defect”). On January 18, 2024, VW first learned of a battery fire involving a vehicle that was charging. After conducting an on-site investigation, VW concluded that the origin of the fire was within the HV battery. From July 2024 through December 2024, VW received three additional reports of fires originating from the HV battery in Volkswagen ID.4s. It was not until December of 2025—nearly two years after it first learned of a battery fire in one of these vehicles—that VW initiated a safety recall related to the Battery Defect, identifying a “quality deviation (mis-aligned electrode)” that “[i]n certain situations…may lead to a fire.” On January 21, 2026, VW issued further safety recalls related to the Battery Defect involving thousands of Volkswagen ID.4 vehicles and disclosed that there have been “thermal incidents outside the ranges identified by the [HV battery] supplier”, but that VW still has not determined “a clear root cause for these incidents.” The complaint alleges that the Battery Defect poses a clear and significant safety risk given the possibility that these vehicles may suddenly and unexpectedly catch fire, as well as poses a potential risk of fire damage to personal property.
