Hot day and as i pulled in to park at home and turned the engine off, the ventilation system lett out a hissing sigh.
Now its unable to produce cold air.
Could just need an AC gas top up? I don't think its ever been done (2012 car)
Or does this point to a leaking system?
It was functioning perfectly fine before the hissing noise
Cheers

Best plan is to hand it into a proper AC place for checking which will mean recovering any R134 left in the system - and weigh it, apply a vacuum to dry the system and at the same time check that it is leak free enough to get recharged/refilled.
All these mobile Car AC systems do lose a small amount of their AC gas charge - that is because they have "rubber" flexible pipes and similar O-ring seals, so eventually having it ending up being "short of gas" during a hot period of weather is not too surprising at its age.
