Recently I had to take my car to the dealership because my 16 fiesta would randomly die on the road. All the lights on the dash would come on, and i'd lose power and steering etc, and then I would have issues restarting. Pulled code with Forscan lite and basically got a bunch of comm errors for various modules. The dealer said that since I have my amp drawing power directly from the positive terminal of the battery, then it was bypassing the BMS and caused damage to the PCM. So they replaced the PCM under warranty,(good thing I didn't underestimate the stigma of Found On Road Dead and got extended/premium warranty, can't remember which), and wrote some note regarding aftermarket amp hookup causing issues.
Got my car back for 2 days now, and it's been working okay, but I really miss my bass >_< I've had my setup since Feb 2018, and had this same issue in August, brought it in, they reset some stuff and was good until recently it happened again, so I want to think that the amp didn't really cause any damage. Do you guys think the dealer was just pointing out the first possible issue? or do they have a valid point? if so, what alternatives do I have for power source?
Another issue, they were saying about my setup was that it was causing a lot of RF interference and caused them issues when programming the keys to the new PCM. They didn't say if the interference only affected the programming of the keys, or if it's bad enough to cause issues for daily operation.
Also, I have already changed my battery, the quick and dirty solution that everyone recommends when there's electrical issue.
