“My car (the SL55 and all SL models) has a Battery Control Module (BCM) also referred to as the Battery Stabilization Control Load Module which shows signs of imminent failure which will lead to a meltdown or fire. I inspected the module after finding that this was a common problem with these cars online. This model of car has been documented to completely catch on fire, even when parked after driving. I have pictures of the burnt board inside my BCM. I am very concerned as it could literally burn my house down. …”
