BMW is recalling more than 720,000 vehicles over a potential short-circuiting problem that may, in rare cases, cause a vehicle fire. And what is the culprit behind this problem? According to the National Highway Traffic Safety Administration, the issue stems from 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," reads the description of the defect.
