Model 2016 Z.
I have been facing this problem for a long time.
AC stops working after some time (usually after 15 minutes). However, after turning off ac for 4 to 5 minutes and again turning it on; the AC worked perfectly for the next 15 minutes.
I've even used it on Motorway continuously for 10 hours but faced the same problem.
What could be the reason?
AC is perfectly chilling. You just need to turn it off for some time after every 15 to 20 minutes.
