Solution to Broken MyChevrolet App

I found a solution, after testing on my phone (using Android 10), it works seamlessly. Fairly straightforward, though you will have to install the .xapk file outside of google play (they would never allow it). Visit https://apkfab.com/mychevrolet/com.gm.chevrolet.nomad.ownership . Download the XAPK ...

Re: How to Access the HV Service Disconnect Under the Seats

..... Have you had the opportunity to access the high voltage service disconnect under the rear seat ( after disconnecting 12V battery ) and disconnect that as well?..

OnStar Investigating

Just finished talking with OnStar about the issue, they said for whatever reason it's not identifying the Spark as an EV hence the reduced vehicle status telemetry. A service ticket has been created (at least for me) and they'll be following up in a few days. They recommend for anyone also having th...

Re: My Chevrolet App

Yikes, as I went to the app on google play to uncheck "auto-update app", it updated... I didn't even have time to drop out of Wi-Fi and mobile data. It seems like they tried to "Modernize" the user interface, but ended up butchering...everything? EV range gone (includes state of charge and approxima...

Re: My Chevrolet App

I've still got my charge status on the app, using version 4.5.0 with key fob subscription active, of course. No visible changes. Is it just the charge status that's missing? There was a wonky update back in February where I couldn't log in and had to reinstall the program and re-agree to terms, whic...

Re: Double Drive Batteries/Range

You, sir, have done your research! Except, NO you can't just "parallel HV batteries". HV batteries are always setup in a series. Typically most are ~400VDC. Regarding series and parallel, I gave the original poster the benefit of the doubt that they either understand what this means, or will pick u...
