I’ve been driving my S100D for a month since a mid-August delivery and this morning as I was accelerating to merge on the expressway, pushing the accelerator hard,I got absolutely nothing after 85 MPH, even though I punched the pedal to the floor ! With a sinking feeling that something was seriously wrong with my brand new car, I finished my commute into work. Later, I called my local service center and reached the rep: Me: I’m afraid there’s something wrong with my car [explanation to him] Tesla: How old is your car, is it a CPO ? Me: Brand new inventory model I bought with 50 miles on the odometer Tesla: [swear I could hear him smiling through the phone] I think I know the problem. You bought a showroom car and we software limit the speed to 85 Mph for safety reasons to ensure a speed limit for demo drivers. I will fix this over the air for you. May I have the last digits of you VIN ? Me: Sigh of relief here is my information. I was so worried that was all my car had ! And that’s my story. I was surprised that I hadn’t accelerated over 85 in my first month, but I’m really not that hard a driver ! So if your car won’t go, maybe it’s been limited !
