BMW recalls some of its PHEV models
BMW has a problem with the high-voltage batteries in some of its plug-in hybrid vehicles. Due to possible impurities in the battery cells’ production process, there is an increased risk of fire in some circumstances.
The total number of plug-in vehicles involved is 26 700 worldwide. One-third of these units are already used by customers; the rest is subject to a delivery stop. According to a BMW Group spokesperson, the issue is “country-specific and not necessarily affecting all models.”
The ‘impurities in the production process of the battery cells’ have probably only occurred at one of the two current suppliers (CATL and Samsung SDI), which is why only some of the vehicles are affected. “In rare cases, these impurities can trigger a short circuit within cells in the high-voltage storage, for example,” says the spokesperson.
Other recalls, similar problems?
Ford had a similar problem with the new Kuga PHEV in the summer. The cause is apparently a safety mechanism that does not reliably dissipate enough heat and pressure.
Significantly larger is a battery recall at Hyundai: in South Korea, over 25 000 Kona Electric models’ recall has already been confirmed. According to reports, Hyundai has decided to recall 77 000 Kona Electric models worldwide voluntarily. Official information on this recall is not fully available yet.
