Volkswagen EV Battery Recall Hits 85,402 With Audi Q4 Added

Estimated reading time: 6 minutes · Last updated: 29 October 2026

Volkswagen's EV battery recall now covers 85,402 electric vehicles worldwide. The count rose after 12,734 Audi Q4 E-Tron and Q4 Sportback E-Tron models were added to the recall database of the German Federal Motor Transport Authority (KBA) on 27 October 2026. The batteries can overheat, and in some conditions may catch fire, once they are charged past 80%, so owners are being asked to stop at that level. The Audi group includes 9,048 US cars from model years 2024 to 2025. Volkswagen Group of America reported those cars to the National Highway Traffic Safety Administration (NHTSA) on 23 October. Only one of the recalled Audis is in Germany. Nobody has yet identified the cause, and no permanent fix has been offered.

certain charging profiles combined with a state of charge over 80% may trigger thermal propagation.

Volkswagen, safety recall report filed with NHTSA

How a 22,524-Car ID.4 Recall Grew to 85,402 Vehicles

The recall began in the US in October 2026. That month Volkswagen filed with NHTSA over 22,524 ID.4 electric SUVs from the 2023 to 2026 model years. Shortly afterwards, data published by the KBA showed the problem reached far beyond one American model.

The KBA is now investigating three separate recalls. Together they cover 72,668 VW Group EVs worldwide, and 9,881 of those are in Germany. The affected batches include the ID. Buzz, ID.3, ID.4 and ID.7 built between 2022 and 2025. Cupra Born cars from 2022 to 2024 are also included.

The Audi entry on 27 October took the global count to 85,402. The Audi figures are heavily weighted towards one market. Of the 12,734 Audis, just one is in Germany and 9,048 are US vehicles. That fits Audi's statement that most of the affected cars were built for North America. It leaves roughly 3,686 Audis spread across other markets, and no country-by-country breakdown has been published for them.

Why 80% Is the Line Volkswagen Has Drawn

Volkswagen filed a safety recall report with NHTSA. In it, the company tied the danger to certain charging patterns combined with a battery charged above 80%, which it said can lead to thermal propagation. Thermal propagation happens when one battery cell overheats and the heat spreads to the cells around it. That chain reaction can end in a fire.

This explains why the interim measure is a charging cap rather than a repair. Volkswagen has not found the root cause. The one tool it has is keeping the battery out of the high charge levels where the risk shows up. Affected ID.4 owners received an email saying Volkswagen planned to apply a temporary setting that holds charging to 80%. That would happen unless they opted out by 21 October.

The cap has a cost for owners. It leaves about a fifth of the pack's capacity unused on every charge. Neither Volkswagen nor Audi has said how much driving range that removes. The cap is a way to reduce the danger while the cause is investigated. It is not a solution.

Why Audi Was Pulled Into a Volkswagen Problem

The warning did not come from the Q4 itself. Audi's Product Safety Committee acted after it was told about battery thermal events in other VW Group EVs. Those vehicles use the same batteries as the Q4 E-Tron.

Audi then ran an internal investigation. It found that the Q4 shared both the battery and the production characteristics of the affected VW Group vehicles. That match was enough to bring the Q4 E-Tron and Q4 Sportback E-Tron into the recall. Audi says it knows of no claims, crashes, fires, injuries or deaths linked to the Q4's battery fault.

This matters for anyone following the group's shared parts. The recall now covers cars sold under the Volkswagen, Cupra and Audi brands, and what connects them is a common battery supply rather than a single model. Each time the authorities have released new information, the vehicle count has gone up. No other group model has been named as using the same batteries.

What US Audi Owners Can Do Before a Fix Arrives

In the US, the filing covers Q4 E-Tron and Q4 Sportback E-Tron cars from the 2024 and 2025 model years. Owners can bring their car to an authorised Audi dealer for a battery diagnostic. Where the results call for it, the dealer will cap the state of charge at a temporary 80%. Until a remedy exists, Audi's advice is to charge no higher than 80%.

Audi plans to mail interim letters to owners explaining the safety risk on 18 December 2026. A second round of letters will follow once a remedy is ready. Audi has given no timetable for that second round.

Owners with questions can call Audi customer service on 1-800-253-2834 and quote recall number 93SK. The NHTSA campaign number is 26V698. The NHTSA Hotline is 1-888-327-4236, and recall details are also available at nhtsa.gov.

What could ease or worsen the recall

The bottom line

In one month, the Volkswagen EV battery recall has grown from a single US filing into a recall across three brands covering 85,402 vehicles. The count went up with every new disclosure. What links the cars is their battery supply, not one model. The interim answer, an 80% charging cap, contains the risk while openly admitting that the root cause is unknown. Audi's lack of reported incidents on the Q4 is reassuring but does not settle the question. The recall rests on hardware shared with vehicles that did suffer thermal events. The next tests are whether Volkswagen can name a cause and offer a fix, and whether the KBA list keeps growing before it does.

What to watch

• Audi is due to mail interim safety letters to US Q4 E-Tron and Q4 Sportback E-Tron owners on 18 December 2026.
• Watch for Volkswagen to name a root cause and announce a remedy, which would trigger Audi's second round of owner letters; no date has been set.
• Watch the KBA recall database for further VW Group models using the same batteries; no date for any further update has been given.
