BMW has another problem with the high-voltage batteries in plug-in hybrid vehicles. Because of possible impurities in the production process of the battery cells, there is an increased risk of fire with several model series. There are a total of 26,700 vehicles worldwide.
A third of the 26,700 units affected worldwide are in the hands of customers, the rest of them have been stopped. Specifically, it is about PHEV versions of the series X1, X2, X3, X5, 2-series Active Tourer, 3-series, 5-series, 7-series, i8 Coupé and Roadster, as well as Mini Countryman from the construction period January 20 to September 18 of this year. According to a spokeswoman for the group, its "country-specific not necessarily all these models affected". In Germany around 1,800 customer vehicles have to go to the workshop, another 3,500 vehicles that have already been produced in this country will not be delivered for the time being.
Background: BMW is currently purchasing its battery cells from CATL and Samsung SDI, and Northvolt will be another cell supplier from 2024. The "impurities in the production process of the battery cells" probably only occurred with one of the two current suppliers - which is why only some of the vehicles are affected. "In rare cases, these impurities can e.g. trigger a short circuit within cells in the high-voltage storage, ”said the spokeswoman.
BMW expects a solution "probably at the end of October". As reported by "kfz -betrieb", BMW has not yet been able to provide any details about checking the high-voltage battery or any repairs that may be required. According to the report, there is only a risk of fire when the batteries are fully charged, which is why the customers were asked in the recall notice not to charge their PHEV by cable anymore - the E-mode can only be used to a limited extent, but there is no risk of fire.
Ford had a similar problem with the Kuga PHEV in the summer: Since there were fires in four vehicles as a result of the battery overheating during charging, customers should no longer charge the battery by cable either. The cause at Ford is apparently a safety mechanism that does not dissipate enough heat and pressure reliably.
At BMW there were apparently three reports of plug-in hybrids caught on fire in the past week, specifically in Erfurt, Herne and Salzburg. BMW has not yet been able to confirm whether the incidents are related to the recall. The comprehensive analysis of the damaged vehicles is still pending.
But it is not the first problem BMW has with its PHEVs: 4,460 units of the BMW 3 Series, 3 Series Touring, X1, X2, X3, X5, 2 Series Active Tourer, 7 Series, 5 and 5 Series Touring and Mini were only recalled in August Countryman known. Internal controls revealed that a bead of sweat on the high-voltage battery from the component period from March 13 to August 6, 2020 was not completely removed during production. "In rare cases - depending on the shape, size and position of the weld bead - the contamination during the initial charging process could cause a malfunction, such as a short circuit in the high-voltage battery," says the manufacturer.
A battery recall that is currently under way at Hyundai is much larger: In South Korea, the recall of over 25,000 Kona Electric has already been confirmed. Hyundai is reported to have committed to a voluntary recall of 77,000 Kona Electric worldwide. Official information on the recall in Germany is not available.
