Why is it that, often when you reach a milestone and you are really happy about it, things go bad afterwards? I recently wrote a, with detailed TCO , and I stick by the conclusion that this car is amazing. However, what I thought was a good old worn out 12-volt battery issue was actually something totally different.
Going back in the afternoon, I decided to reach a V3 Supercharge closer to home. Range was down to 14 km at arrival, and the car charged really fast. Started out at 254 kW, and after a bathroom and coffee stop in the mall at the site of not more that 20 minutes, I was good to go with 80% SOC . But then…I was unable to release the charge plug and the charge indicator went red. The display said “Unable to charge, release plug and try again. ” .
I googled a bit, and I tried to turn off the car for a few minutes from the service menu and then wake it by pressing the brake pedal. No difference. One suggestion was to leave the car overnight with the charge plug in and hope it might magically have come to its senses in the morning.Well, the next morning I found a message on my phone sent from the car at 4:00 am: “12 volt battery needs replacement, schedule service now.
This raises the question: Why did I get the “12 volt battery needs replacement, schedule service now” message? I have asked this question in the post service feedback form to Tesla, but I don’t expect an answer other than in the line of: Diagnosis was performed, defective parts replaced .
