takata has had to replace airbags thrice on same cars.. I speak from first hand experience, and that fiasco will not end anytime soon. Your grandchildren will also see them being changed out.
JATCO CVT is nothing new, the same vandoorne belt system is also in the corolla, city, lancer and if you recall the subaru justy auto from the 80s - they also had it.
In USA consumers will kick the manufacturer really hard if the thing fails too often look up Ford Focus DSG buy back if you dont believe me.
Point is - Im not ruining this thread, Im just saying that if you own a vandoorne belt CVT, make an accrual account that can finance replacement of your gearbox when it fails. (which it does).
They are not even remotely reliable as the old stepshift gearboxes and dont work well under stress (like climbing a hill with a load)
At best you can install additional air/oil heat exchangers to cool down the oil - this can assist in somewhat elongating the life of it. It is also mandatory to immediately warm up the oil of a CVT so its hydraulic properties are not out of whack. (this is why larger engine CVT vehicles like 3.5 litres etc, have 2 warmers and 2 coolers for the transmission depending on the load and outside temperature).
The immediate warm up in your tiny econobox cars are handled by the coolant/cvtf heat exchanger either in the radiator or on the gearbox depending on design. If you experience the car has slowed down and is not applying much power anymore the transmission may have overheated - stop and let it idle for about 20 minutes to cool it off, If you keep on pushing it harder to drive in this condition the transmission will fail.
