His theory is that solder traces/joints in the electronics are developing cracks.
The car is 7 years old, daily driver. Things break over time.

considering that it seems that your problem is somewhat a lone duckling, being that very few others are complaining about similar issues, i would say that while cracked or damaged circuit boards are possible, it's quite a distant possibility. damaged circuit boards generally have external factors involved in the damage. generally, i've only seen it on 15+ year old vehicles, and usually in cases where the circuit boards are improperly mounted, exposed to the elements, or subject to extreme heat cycling. none of which should really be the case in these cars.
is this mostly happening at your home? check if led light bulbs are on. many cheaper models emit enough EMI to mess up the thought process of passing geese flocks...
