A lot of times original equipment manufacturers make the best for your car when you go and get something that submarket it's not going to work as well as it would getting it from the dealership so that's probably where your problem lies the one from the dealership works the one from AutoZone or O'Reilly's does not work

If the dealer is calling a head gasket i would trust them. Water on the dipstick isnt something you would see. chances are coolant is getting into the cylinders and burning as you drive so you are probably low on coolant and theres enough to flow when the engine rpm is high. Which would allow some heat when driving and none when idling. Also if there was water in the engine, it would sit at the bottom due to oil being lighter than water so if anything it would just look like you ave to much oil on the dipstick. The steam your seeing might actually be exhaust fumes from a blown head gasket

Check the fuses, or the whole knob assembly went bad.

It sounds like your fans are not operating properly. When u accelerate cool air is forced through the radiator & condenser which can cause that problem , u can change the thermo. for maintenance anyway. Use fresh 50/50 coolant mixture. Ck those fans

I would check for heat damaged fuel pump connectors and also replace the fuel pump relay.
