I just had my i3 towed, dead as a door nail until the guys tried to jump start it, but all the safeguards on the vehicle shut them out. So we are assuming it’s a battery thing. The lights flashed and clicked until it went totally dead and before this happened I had 50k on the car and used the REX 2 miles to get home. Shutting it off the motor still ran and I plugged in the charger. Today it had zero charge and was mostly dead. Unplugging it from the charger Nd closing the port door, that locked and would not open again. Couldn’t get it into neutral for towing Nd was forwArd facing in my garage, which then they had to drag it out on skates and onto a flatbed. Thankful I have triple AAA. but they tried for over an hour and a half to try anything to get it out of the garage. I will never front face in my garage again. I love this car , am hopeful, so will see what they say. It’s a 2015 Rex. And has almost every option you can get on it.
