BMW says the problem is the water pump's electrical plug connector.
"Blowby-liquid from the positive crankcase ventilation system may collect on the intake air hose. If this occurs, then this liquid could drip onto the plug connector. Over time, this could lead to fluid ingress into the plug and the possibility of a short circuit." — BMW
BMW believes only about 1% of the vehicles may have problems, and the automaker says "thermal events" can occur, but a fire is allegedly rare.
BMW learned about the problem from a thermal incident in South Korea, and a search for other events discovered a water pump incident in the U.S.
As of August 2024, BMW is aware of "18 customer complaints, concerns, and/or field instances, in the US market, that relate, or may relate, to the issue identified in this report."
However, there are no known crashes or injuries.
BMW water pump recall letters are expected to be mailed October 4, 2024. BMW dealers will install protective shields, and if necessary the water pumps and plug connectors will be replaced.
The shield will be installed to divert any fluid that might drop down onto the pump from the positive crankcase ventilation intake air hose.
