apparently my Supra is due one - there are two different types of coolant used- the dealer has quoted £150 (about US$170) - thats stealing if the car uses the cheap fluid, not quite daylight robbery if it’s the expensive one.
anyone not bothered ?
Your car's AC, like your home, is a closed system. If it needs to be topped up then you have a leak, which is a problem that should be covered under warranty.
Also, overcharging your AC is a thing too....It needs to be in a certain range.
