The MECH said Radiator fluid was leaking through the seals causing electrolysis.
They took care of it NO PROBLEM.
Toyotas are top quality
My problem had nothing to do with your mysterious problem.
My problem had to do with my user error and a small quirk with these spark plugs getting tightened correctly.
Toyota's are still the most dependable vehicles out there, I have had excellent luck with them for 20 years now and wouldn't want to depend on any other vehicle.
