I have the kadjar tce modes as a company car. So I spend long days traveling in it and in South Africa with temperatures reaching 35-40 deg celsius a perfect aircon is a must. But i Have now found if it gets over 30 deg outside temp and i run my air-con at full speed it will stop cooling and work as a fan only for at least 5-10 min and then start cooling again and no switching on or resetting or even stopping the car switching it of and restarting it will cure the problem. And then suddenly it will start again and work perfect. The longer u use the air-con the more frequent the down time will be.
