Zwift play right controller issues, stops working and intiates braking

I have now experienced a serious issue with two different play controllers and to be more precise, the right one. They work fine for around 5-6 hours of riding, then suddenly vibrates for 2-3 seconds and starts braking. A reboot of the controller does not work, and if you do a calibration it works for 30-40 minutes then the scenario repeats itself. I have already got one replacement from zwift, but what is the odds for receving another faulty unit. Anybody else with the same issue?

I suspect sweat/moisture ingress, I’m on my 3rd set already for similar issues.
