Good Morning [Name redacted],
I sincerely appreciate your patience while we reviewed your inquiry about the Electric Vehicle service package, and I hope you are doing well today.
After corresponding with my product specialist team, they have advised me that at the conclusion of the 3 year EV service package, you may continue to get the EV services by subscribing to a Car-Net package. Additionally, there is not a stand-alone EV subscription package.
While I cannot speak for other automotive manufacturers and their delayed charging services, I have been sure to document the feedback that you have provided me for internal review. We take this information seriously as it is a key tool in understanding how we can improve the features that we offer.
If you have any additional questions or concerns, please don’t hesitate to reply directly to this email and let me know. I am always happy to help in any way that I can.
So, the bottom line is that you can keep the CarNet remote functions working if you subscribe to the full suite of CarNet services at a cost of approximately $18/month. There is no plan to offer a less expensive reduced function service for the EV specific functions as is offered for the initial 3 years.
