Fellow Tesla fans,
I usually don't turn to the forums for help, but I'm stumped and could use some real-world feedback to see if my issue is isolated or a larger problem.
Some background: I received my P85 in December of 2012. I'll also be honest that I'm a huge fan of Tesla.
That aside, there is one thing that has been consistently nagging me. We have two EVs and regretfully don't have the electrical capacity for both a HPWC and the J1772 charger. Instead, we just use the J1772 charger for both cars and one of us trickle charges. Our garage is a pretty typical California garage -- so not lots of space (there's maybe one inch to spare in front of the S when it is charging, right near the garage door, as I back the car in...) and about a foot between it and the other vehicle.
When I charge off of the 120V outlet in the garage at night, it often is still charging right up until the moment I get in the vehicle. Upon getting into the vehicle, I notice that the exterior temperature on the driver's display indicates easily 30-40 degrees Fahrenheit warmer than the garage. Worse, in the most recent firmware updates, the touchscreen becomes unresponsive to touch events. Imagine hitting the Homelink icon on the infotainment display and the menu staying stuck down for minutes, without me holding my finger on the display.
If I drive the car out of the garage, the airflow seems to cool things down somewhere where the problem goes away and the touchscreen becomes responsive.
So when I 120V charge I **never** hear the cooling fans come on in the vehicle to keep it cool. It doesn't seem to do this with 240V or Supercharging. Interestingly, charging outside (at a public station) doesn't seem to yield a problem.
I've noticed somewhat similar behavior in cold weather (like in Tahoe) where the car is plugged into 40A 240V service outside; the car seems to derate itself to 30A without me doing anything and the temperature sensor thinks it's below freezing even in the morning -- even thought by that point it has warmed up over 50 degrees.
Other than the touchscreen inconvenience, you also either get blasted with cold air from the AC because the car thinks it is hot (when it isn't) or worse, in the winter, the heat goes into overdrive. I'm also worried about the effect on the components.
I took the car to service shortly after delivery and the then service manager told me it was "a feature." (Yes, exact words.) I had the car checked this past week at service, where they did a 24K and also checked things and couldn't duplicate the problem. I have videos of this issue -- so I thought before I'd try to raise this with Tesla again, I'd find out if others have noticed the same behavior.
Thanks as always for your help,
Matt
