BMW is recalling over one million cars and SUVs after documents revealed a possible overheating issue under the hood. The U.S. National Highway Traffic Safety Administration posted that a heater in the vehicles can be subject to irregularities in manufacturing, even when the cars or SUVs are not in use. Four drivers have filed reports after injuries, and dealers are working on replacing wiring and connectors. A spokesperson for BMW said owners should leave their vehicles outside to be cautious.
