Thousands of PHEV models have a battery module that may short circuit, potentially leading to thermal runaway
Volvo is recalling thousands of plug-in hybrid vehicles in the U.S. due to a defect that could cause a short circuit when parked and fully charged, posing a serious fire risk. The issue is particularly concerning as it could occur overnight while the vehicle is parked in a garage.
As a precaution, Volvo is urging owners not to charge their vehicles until the recall is addressed. The recall affects 7,483 models, including plug-in hybrid versions of the 2020-2021 S90, 2022 V90, and 2020-2022 S60, V60, XC60, and XC90.
Battery Defect Linked to LG Cells
The issue stems from a battery module production defect, which Volvo says could trigger a thermal runaway event. While details remain unclear, the batteries, supplied by LG, may contain faulty cells prone to internal short circuits.
Volvo first identified the problem after a customer reported a “thermal event” on February 6, 2024. This led to an investigation that concluded earlier this month. So far, Volvo is aware of two related incidents, though neither resulted in injuries, crashes, or fatalities.
Free Repairs and Software Update
Volvo will begin notifying owners in May. Affected customers will be instructed to bring their vehicles to a dealership, where technicians will inspect the battery module for any cell deviations. If defects are found, Volvo will replace the battery module at no cost. Additionally, all recalled vehicles will receive a software update to enhance battery monitoring.
