So, I'm dealing with my first real issue since I got my roadster. I paid about an extra 10 grand specifically so I would have the 'sport' edition with the additional horsepower and torque. It turns out, performance mode has pretty much never worked since I got it. The console shows the text in 'red' which, idiot me, I assumed meant 'red for really fast' or something. But, actually, it's supposed to stay white and if it turns red, that means it has been disabled. There has been lots of discussion on the forums about how temperature sensitive that mode is, but that's not the issue I am having. If I put the car in performance mode it will turn white, but then the *first* time I do a launch it almost immediately turns red; even if it is cool outside and the car just started up. If I continue to drive more slowly, it will go back to white again, but the instant I put my foot on the accelerator, it turns red again. It just refuses to stay in performance mode if you, you know, actually try to be performant. The car recently underwent it's annual inspection and cleaning, and got a clean bill of health. I have dropped it off at the Tesla place in St. Louis but they are being honest with me that they really don't know very much about the Roadsters and are immediately stumped. This is definitely a major concern of owning a Roadster I believe. If I owned a Ferrari, there are easily five shops in the St. Louis area who would be more than qualified to fix anything on it. But, with the Roadster, the only place I can go is the local Tesla service center and..if they don't know anything about the car..that presents some major challenges. They are contacting techs throughout the country who know more about the Roadsters to help diagnose the issue. One theory they have is it could be a failing sensor inside the motor. I shudder to think what that repair might cost. Has anyone else ever encountered this problem with their Roadster and, if so, how easily was it fixed? Other than the fact that it won't stay in performance mode, everything else on the car has been rock solid and running beautifully.
