Citroen C5 Aircross 2021 AC issue

[suryamullapudi]

My Citroen C5 Aircross AC is getting cut off after driving for few kilometers and also sometimes it doesn't blow cold air from the start itself. When I accelerate the car or apply sudden brakes the cooling starts again.
It's acting so strangely, the car is in company service center from 1 week and they refilled the gas changed the thermostat and yet the issue is not resolved. Even the people at service center are unable to find a solution to the car issue.
The AC sometimes work perfectly too.
Can someone please help me out or any one with a Citroen faced a similar issue with their car.

Sorry, can't really help with that sort of issue on a Forum - needs further investigation, but sounds like an electrical issue if the A/C is playing up when applying the brakes.
