NHTSA Complaint #11531093 — 2007 BMW 335I

The battery light would come on randomly when using the AC. We just took the car out for a 30 minute drive and parked in the garage. When we went back out to get something out of the car 10 minutes later, the car was smoking. We popped the trunk and the battery was on fire! I researched if there were recalls of faulty wiring and came across an article that mentioned this happening when the AC was on. It also mentioned issues with PCV valve heater recalls. After we bought this car, we noticed burn marks around the area near the battery when we replaced it. We wonder if the same thing happened to them but not as much damage. One recall involves the heater for the positive crankcase ventilation (PCV) valve, and the other recall involves wiring and electrical connectors in the system that controls air flow for heating and air conditioning. Can we get help from a BMW dealer to fix this issue? Please advise. Thank you.
