Yep. I've had my '21 MYP for 4 weeks and 2 days now. The first two weeks went perfect. Then on the third week, first thing Monday morning, I was unable to preheat the car with the app - 'Failed to turn on climate' on the screen. Car had no heat in 30 degree weather. In the afternoon when it was warm, I also had no A/C. This lasted all week long. Side Note - Dog Mode was unavailable as well, even though I don't have a dog.
Now, this past Monday, I turned on the climate (through the app) and just like that, working again. Car was nice and toasty when I opened the door. A/C is working again too!
My Service Appt. is for 3/30, but I'll probably postpone if it continues to work well.
