Hi, Gave the door latch a good clean and spray with a silicone lubricant (not wd40) and has so far been fine until this morning. I had to defrost the car this morning. I drove the car for 40 minutes or so and pulled into the garage to grab a coffee. The door wouldn't open from the inside this time. I had to put down the window to let myself out. 5 minutes later after parking at work I was able to let myself out using the inside lever without issue. Can't be a coincidence that all three issues have occurred when the temperature has been below zero. Most likely some water ingress into the mechanism and it is freezing over now that the weather is getting colder however I have emailed my local dealer for some advice.
