Has anyone had recent issues with Climate Control like this: I've had my Model S since December 2012. There were no problems with climate control for almost exactly one year. Then, starting at the end of December 2013, (after the 5.8.4 release, I believe) my cc started misbehaving. I've submitted some interesting pictures and videos I've taken, as well as iPhone screen shots, to my service guys, of the bad behavior: heating up well beyond the temp I set it at. For example, I have a screenshot showing the CC set to 70F, the interior cabin temp at 78F, with "red" (heating) coming from the vents. I also have provided pics and vids of numerous cases - both video of the car showing the climate screen on the interface, and screenshots of the Model S app - where I set the climate control to 70F and it eventually climbs to 80F because the heat stays on. I brought the car in for annual service 2 weeks after this started happening, expecting they would fix it. And yes, they looked at the climate problem. They acknowledged it - "yep, that's a problem." And gave me the car back with no solution - only a promise to try to figure it out eventually. That was over two months ago now. And I should say that I did have a work-around that worked for a while: if I set the temp to 66F, it -often- ends up hovering around 70F. Recently has stopped working reliably. Now, usually, 66F goes one of two ways: Cabin temp stays at 66F ("working" as designed - so it's cold in the car) Cabin temp climbs to upper 70s, getting as hot as 80F (everyone sweating, having to put the windows down when it's 30F outside). So basically now, I'm constantly futzing around with the climate control settings - like I'm back to driving the 1981 Chevy Citation I had when I first got my drivers license (with the classic red/blue slider that controlled the heating and cooling). But seriously - I haven't driven a car with this kind of problem in over 20 years. I do recognize that Colorado can present a unique challenge for warming/cooling a car. For example, on a cold day (25F outside) the car may still need to be cooled because the sun is baking the inside (despite having the windows tinted as dark as the law allows). But my Model S got it right for the first year - until something went awry in December. It seems like either my car has a hardware defect, or there is a firmware bug. So my questions to all of you are: Has anyone else experienced this climate control behavior? If so, have you presented it to Tesla, and what did they say? (i.e. is this just my car, or is it more widespread) Does anyone have any suggestions as to how to escalate this within Tesla? So far, they don't seem interested in solving it for me despite their admittance that it is behaving inappropriately. (i.e. how should I escalate this) Thanks in advance for any feedback or suggestions.
