It’s either a faulty chip(s) or resistance in the motor. Seeing it’s one of your most run cars it will have more wear n tear including picking up metallic dust from worn braids like a magnetic vacuum cleaner.
I would put a new(er) motor in it before frying any more chips.
I’ve also seen ssd chips burn up immediately after installation with motors that are proven to be ok. I even managed to catch it on video.
