1 recall across 1 model year
The BMW M340xi has 1 recall affecting the 2020 model year, where a software error in the engine control module can allow the starter motor to run longer than intended, overheat, and ignite nearby combustible material in the engine compartment, raising the risk of an underhood fire.
The starter motor sits in the engine bay surrounded by wiring, hoses, and other materials that can catch fire if exposed to enough heat. When the engine control module software fails to cut off the starter at the right moment, the motor keeps running and builds up heat beyond its normal operating range. The fix involves a software update to the engine control module to correct the shutoff behavior.
