I am a new owner of a used 2013 model and am so happy this board exists. I recently had an experience of my car not starting with several warnings appearing (ABS and airbag warning) after being parked in the cold while I was at work. The dealer says there was a bad cell in the 12V battery and replaced it, but after reading all the posts about the electrical failures in the middle of the road, I'm a little unsure if I should keep the car. I love it otherwise but now am a little scared I will have an electrical failure while driving. I did see the spreadsheet on the Check EV warning thread and it seems to be pretty common. Did the firmware update seem to fix the Check EV warning issue? Do any of you regret buying this car? Thanks in advance.
