Aircraft
Upon takeoff; I realized that top latch of pilot's door was not locked. I immediately informed Tower that I would need to go-around and land plane. Tower approved my turn to downwind; base and final. I landed the plane and had my co-pilot walk around outside the of the plane to secure the top latch of pilot's door. I then proceeded to inform Tower that I was requesting to take off on my IFR flight plan.I have had a problem with the door closing on my 2015 Cirrus SR22 for the past year. It has been in the shop on at least X occasions to repair the problem. Every time the dealer/service center says the door has been repaired when in fact it has never been repaired correctly. Cirrus seems to be indifferent to this problem. From discussion with mechanic I believe this problem is not unique to this particular airplane.
Cirrus SR22 pilot reported after departure their door became unlocked and that this was a recurring problem.
