Volkswagen batteries at risk of catching on fire.

The Non-Financial Ledger

Imagine you buy an electric car because you want to do the right thing. You’re paying a premium for cleaner transportation and the promise of modern technology. A major selling point is the fast charger — VW told you, repeatedly, that the car charges from 10% to 80% in about 30 minutes at a Level 3 DC station. You bought that promise. You built your life around it. You charge the car overnight in your garage because that is the obvious thing to do with an electric vehicle you park at home.

Then a letter arrives. It tells you the battery in your car can catch fire. It happened to other people’s cars — not just while charging fast, but while the car was just sitting in a parking lot, not plugged in at all. One happened while someone was driving. The letter tells you to stop using Level 3 fast chargers. Stop charging past 80%. Don’t charge it indoors overnight. Don’t leave it in your garage while it charges.

That is your garage. The one attached to your house. The one where your family sleeps thirty feet away.

Now you’re doing nightly math about risk. You’re calculating whether you can make your morning commute on 80% of a battery you can’t top off quickly. You’re researching outdoor extension cords. You’re explaining to your partner why the new car has to stay in the driveway all night in the rain. You are, in the language of the lawsuit, no longer able to “safely park [your vehicle] in your own garage.” But you still owe the monthly payment. You still owe the insurance premium. Nothing about the financial obligation changed. Only the product underneath it did — and Volkswagen knew that before you signed the lease.

Plaintiff Robert Warren leased a 2023 ID.4 in February 2024. He received a recall notice in March 2025. Technicians installed a software update. They did not replace his battery. He continued to drive a car with a battery that, by VW’s own admission, may contain misaligned electrodes capable of causing a fire, with a partial software patch standing between him and an uncontrolled thermal event.

Plaintiff Timothy Chen leased a 2025 ID.4 in August 2025 — more than a year after VW had confirmed the root of the problem was in the HV battery, and months before VW finally issued any public recall. He had no way to know. The information was in VW’s exclusive possession. VW used it to keep moving cars off the lot.

Legal Receipts: What VW Put in Writing

The following are direct quotes from official NHTSA recall filings and the class action complaint. No paraphrasing. No spin. Just what VW and its battery supplier put on the record.

“Individual battery cells in certain high-voltage (HV) battery cell modules . . . may contain misaligned electrodes . . . . In certain situations, a misaligned electrode in the HV battery cell may lead to a fire.”
— Recall 25V-836 (Dec. 15, 2025) and Recall 26V-028 (Jan. 21, 2026)

• VW used the word “fire” in its official recall filing. This is an admission, in regulatory documents signed under federal law, that the defect carries a fire risk.
• The phrase “in certain situations” does not limit the risk to charging or high-speed use. As the complaint documents, fires occurred in parked vehicles that were not charging at all.

“there appear to be thermal incidents outside of the ranges identified by the supplier as potentially having a defined hardware anomaly.”
— Recall 26V-030 (Jan. 21, 2026)

• This admission means that fires were happening in vehicles that VW and its battery supplier had not already flagged as defective. The known-defective population was not capturing all the problem cars.
• VW simultaneously admitted it still had not determined “a clear root cause” for these additional incidents, meaning it launched the biggest of its three recalls without fully understanding what it was recalling.

“self-discharge detection software would have triggered a warning in advance of at least three known incidents but that certain vehicles lacked the SDD software.”
— Recall 26V-030 (Jan. 21, 2026)

• This is a documented admission that a safety system capable of warning drivers before a fire was not installed in all Class Vehicles. Three incidents could have triggered warnings before they escalated. They did not, because the software was absent.
• The complaint argues this software should have been installed in all Class Vehicles before sale or lease, given established knowledge about EV battery fault detection requirements.

“The recall population was determined by production records. The supplier of the high voltage (HV) battery identified battery cells within a production period where a quality deviation (mis-aligned electrode) has been confirmed.”
— Recall 25V-836

• VW’s first recall was limited to a specific production window defined by the battery supplier’s records. However, Recall 26V-030 later admitted fires were occurring outside those flagged ranges, which means the production-record-based population was under-inclusive from the start.
• The first recall covered only 629 vehicles. The third recall covered 43,881. The gap between those numbers represents the vehicles that continued to be driven by unknowing owners during the months VW took to expand the recall scope.

Public Deception: What They Sold You vs. What They Knew

VW built its marketing for the ID.4 around the battery and its charging capability. Those same features were the ones hiding the defect.

• What VW claimed: The ID.4 features fast DC charging as a standard, premium capability — “SK On cells and modules charge 10% to 80% in about 30 minutes when charging at 170kW or higher.” This was specifically referenced in dealer marketing materials and the 2025 Retail Order Guide. What was happening: VW knew from January 30, 2024, that using a Level 3 DC fast charger on one of these vehicles had resulted in a confirmed battery fire. It continued marketing DC fast charging as a key selling feature after that date, for months, without disclosing the fire risk.
• What VW claimed: The 82 kWh battery in the 2023 ID.4 provides an EPA-estimated range of up to 275 miles when fully charged. What was happening: Owners were eventually told to cap charging at 80%, reducing effective range and making the advertised range figure unachievable under the recall’s own safety guidelines.
• What VW claimed: The ID.4 is “the future of driving” with “charged up style, energized handling,” marketed as safe and technologically advanced with two years of complimentary Electrify America DC fast charging network access included. What was happening: VW was simultaneously investigating multiple fires traced to the HV battery and had not disclosed the Battery Defect to consumers, regulators, or the public.
• What VW claimed: The HV Battery Limited Warranty covers defects in material and workmanship for 8 years or 100,000 miles. What was happening: The complaint alleges VW never intended to repair or replace the Battery Defect during the warranty period, and as of filing, had provided only a software update rather than battery replacement to affected owners including Plaintiff Warren.

Profit-Maximization at All Costs

The complaint documents a pattern of decisions that prioritized continued sales over disclosure of a known safety hazard.

• VW confirmed a battery fire on January 30, 2024. It did not raise the issue to its own Product Safety Committee until November 26, 2025. That is approximately 22 months of confirmed knowledge with no internal escalation to the body empowered to issue recalls. During that period, VW sold tens of thousands of additional ID.4 units — 17,021 in 2024 alone, and 22,373 in 2025.
• The complaint directly alleges that “VW knowingly, actively, and affirmatively omitted and/or concealed the existence of the Battery Defect to increase profits by selling and leasing additional Class Vehicles.” It further alleges that “Defendants intentionally concealed that the Battery Defect presents a safety risk to consumers . . . and the public.”
• The complaint states that “the delay, inconclusiveness, and under-inclusiveness of VW’s recalls have allowed Defendants to maximize sales of the Class Vehicles.” The first recall covered 629 vehicles. Within weeks, that number expanded to 629, then a parallel recall added 670 more, then a third recall swept up 43,881 total — a number that was presumably knowable earlier had VW moved faster to investigate its own supply chain.
• VW’s initial Recall 25V-836 did not schedule owner notification letters until January 30, 2026 — more than six weeks after the recall was initiated. Owners of vehicles identified as defective continued operating those vehicles without knowledge of the risk during that window.

How Capitalism Exploits Delay: Time as a Corporate Weapon

From the first confirmed fire to the first public recall, VW had at least a 22-month window of private knowledge during which it continued to sell, lease, and market the vehicles it knew had a fire-prone battery.

• January 30, 2024: VW confirms the origin of a Class Vehicle fire is the HV battery. This is the earliest documented date VW possessed confirmed knowledge of the Battery Defect. No recall is initiated.
• July–December 2024: Three additional thermal events are reported and investigated, with SKBA identifying shifted electrodes. No recall is initiated. VW sells 17,021 ID.4s in 2024.
• June–September 2025: SKBA conducts CT analysis of damaged modules. In late September 2025, SKBA performs a Tear-Down Analysis revealing shifted cathodes and then recognizes the same pattern in CT images from June. Still no recall — and VW is selling cars. In August 2025, another vehicle catches fire while charging at a Level 3 DC charger in Colorado.
• November 26, 2025: VW raises the issue to its Product Safety Committee for the first time — nearly two years after confirming the HV battery as the source of the fires. The decision to issue Recall 25V-836 is made on this date.
• December 15, 2025: VW amends Recall 25V-836 to add 318 more vehicles. Owner notification letters are not scheduled until January 30, 2026 — meaning owners of identified defective vehicles spent another six weeks without official notification.
• The complaint documents a separate NHTSA complaint filed March 22, 2023 by a driver whose 2023 ID.4 caught fire while charging on a DC fast charger on March 10, 2023 (NHTSA ID No. 11513315). This predates VW’s stated January 2024 discovery date, and the complaint alleges VW had a statutory duty under the TREAD Act to monitor and analyze all NHTSA complaints about vehicles it manufactures.

Supply Chain Complicity: The Battery Supplier at the Center

The Battery Defect did not originate inside a VW factory. It originated inside the cells manufactured by SK Battery America (SKBA), a U.S. subsidiary of SK On — and the paper trail shows VW relied on SKBA’s own investigation to define the scope of its recalls, with consequences that proved too narrow.

• The HV batteries in the Class Vehicles are manufactured by SKBA. The battery modules contain SK On cells. This means the quality-critical component at the heart of the fire risk was produced by a third party, not by VW directly.
• After the July 2024 fire in California, the damaged HV battery cell modules were sent to SKBA for analysis — meaning VW’s investigation depended on its own supplier to evaluate its own parts. The conflict embedded in that arrangement is documented by the outcome: SKBA’s initial analysis did not identify all affected vehicles, and VW’s first recall, scoped using SKBA’s production records, covered only 629 vehicles out of what would eventually be nearly 44,000.
• It was not until SKBA performed a Tear-Down Analysis in late September 2025 — more than a year after receiving damaged modules — that the company recognized shifted cathodes in CT images that had existed since June 2025. The complaint documents this sequence as part of the delay that allowed VW to continue selling vehicles.
• Between December 2025 and January 2026, SKBA identified a second, separate hardware issue in the same batteries, capable of producing a different shifted electrode condition. This triggered Recall 26V-028. Two distinct manufacturing problems in the same battery line, both producing electrode misalignment, both discovered incrementally rather than through proactive pre-sale quality control.
• Recall 26V-030 admitted “thermal incidents outside of the ranges identified by the supplier” — meaning fires were happening in vehicles SKBA had not flagged. The supplier’s own production-record-based population definition had failed to capture the full scope of defective batteries already in customers’ hands.
