do you have it on a battery tender?Hi, what happened with the door problem?
I have the same problem with my 2020 GT, although my battery appears to be fully charged and the windows go up (not completely) and down, so I can open the drivers door with the safety latch. It was serviced by McLaren one month ago, no issues, drove it multiple times in the days before the problem with no problems. Now the doors won't open, multiple warnings on the dash re parking brake, tracking, doors, boot. Wing mirror adjustor is flashing. Engine was starting and car driving despite the issues, but now won't start. Battery says 44 days and the stereo etc works. So frustrating. I'll have to have it shipped if it can't be resolved as no McLaren dealers where I live. Warranty expired 2 weeks ago :-(
If not, hook it up for 24 hours without touching the car or checking it and see
