That happened to me too. My girl sat for 2 weeks and went into power save mode or whatever it’s called. I charged the battery and tried to start her again, she started but i had warnings that flashed then went away. I took her out for a drive and she went into limp mode with very weak acceleration. I pulled over because I couldn’t go more than 10 mph. I shut her down waited a few minutes then restarted. Everything was fine then and has been since. I keep her on a battery maintainer now and it’s been great. As others have mentioned not to connect directly to the battery. Hope it all works out and is a simple fix.

Hi everyone,




Yesterday I wanted to take my car for a ride, but unfortunately, it wouldn’t start. My car has been sitting in the garage for 9 days I have a NORCO battery charger - maintainer - conditioner for AGM batteries set up since day one because I don’t daily drive my vehicle. I only use it on weekends for pleasure.





Today, when I tried starting it, I got a bunch of error codes and sensor faults. I’ve attached a videos for reference. If anyone has experienced something similar or has any advice, I’d really appreciate your input.





It’s very frustrating, and I’d like to avoid towing the car to the nearest dealership if possible. I know it’s under warranty, but I’d prefer to get it running myself if there’s an easy fix. Thanks in advance for your suggestions!

Try disconnecting the battery both terminals let sit for 30 minutes then hook it back up and try like a reboot.

There is a thread on this, it is a software issue and covered under TSB 52142/52286

And yes, it does look exactly like a voltage issue but it is not

disconnect the battery and wait for 10ish minutes for the system to clear all faults, then reconnect and try again

This fixed mine it only happened once then never happened again.
