Hi, Im having problems with a leak on the air con system, Its leaking from around the pipe on the aluminium joint next to the radiator top up bottle, The green tracing oil can be seen around the joint. Had someone out to look at it and has told me that it's the new R1234yf gas which is causing problems with the rubber pipe work. i doubt Mazda would want to help as the car is now 4 years old. Anyone else had problems caused by the new refrigerant ?

There was a problem with dodgy condensers on early models. Cheap Chinese copper or aluminium coils.
I don't think R1234yf affects the hoses any more than R134a does. I would ask a Mazda dealer to look at it. If it is faulty materials Mazda may well contribute towards the costs even if it is outside warranty.

Thanks for the reply. Phoned Mazda UK but they say there was no recall with the Air Con, But they did pick up 2 others, Passenger airbag and speed sensor, Engine can over rev or something like that, which are going to be done FOC, And they are going to check the pipework on the air con and see what happens next with regards to a warranty claim.

Graeme,

There were no recalls on the CX-3 in the UK in relation to air conditioning problems as recalls are only done in respect of safety problems, whereas air con problems are just a damn nuisance :evil: I am aware that Mazda Japan did issue 3 Technical Service Bulletins (TSB) to Mazda dealers worldwide for manufacturing faults with the condenser, evaporator and control unit (the 3 dials bit) elements of the air conditioning system on vehicles with production dates up to late 2016. Such TSBs are internal documents to assist dealers resolving a customer reported problem with their car. I'm not aware of a TSB covering the particular problem on your car as these TSBs are not widely advertised, but would have hoped that Mazda UK could check this out. I hope you get a satisfactory FOC resolution of the problem.

For your interest, it is possible to see if there are any outstanding UK recalls on a car by checking the Outstanding Recalls section underneath the MOT History section via the Gov website https://www.check-mot.service.gov.uk/

As St3v3cx-3 says, it was not a recall, it was a TSB details of which were put on this site. I had my condenser changed under warranty because of a leak caused by poor quality material.
