Naw. I've been fixing 35 year old ECUs for a while now. Through hole stuff is cake.
Potted SMD stuff? That's not something 99.99% of DIYers can do correctly.
Eventually, every electronic thing will die. And when you can't even get new components, you'll have to go without or buy a new vehicle.
Eventually, I'll be getting an old Deisel truck with no electronics at all. That will outlast us all. 😁
