Hey folks,
I took delivery of a 2013 Model S P85+ through the Tesla CPO program about 2 years ago and recently noticed a dramatic slowdown in supercharge rates. I used to supercharge at 90kW+, and now only charge between 40kW-55kW under ideal conditions. My supercharge speeds have dropped by about 50% since I took delivery of the car.
I escalated with Tesla service. Tesla confirmed that my charge rate had been software limited through an update and canceled my service appointment:
>Recently, our product engineers have updated the charge profile in your vehicle's battery management system. This adjustment/reduction to peak charging power does add additional charge time, but is designed to protect batteries that have higher amounts of supercharging events to improve battery longevity. [...] Tesla offers no guarantee or warranty on supercharging speeds. Even though the vehicle you bought was certified, it was pre-owned, therefore, some wear and tear should have been expected.
The charge rate reduction is being attributed to "higher amounts of supercharging events", but that took place before I owned the car and Tesla did not disclose the condition of the battery at the time I took delivery. It now takes about an hour to get enough charge to continue my long-distance trips. My vehicle is still under warranty, but Tesla doesn't believe this is a warranty issue.
Anyone have thoughts or suggestions? I'm feeling pretty bad about this one - I was a big advocate for the Tesla used market since my CPO experience had otherwise been great.
