HI, well just came back from SC. the guy who took a look at it, immediately noticed the sound and even admitted the vibrations in the wheel. I told him about the issue, explained everything we know from this forum and that tesla guys won't fix it, but he was confident enough to say "not here, we'll get it fixed" lol, 2 hours later, the car is fixed! Thats what they tell me lol. I didn't even get my hopes up before getting in to check it out. and Yep , no change whats so ever. same annoying sound, vibration in the steering wheel. I called the guy who worked on it who was pretty cool about all of this, and he said he drained and refilled antifreeze coolant... and he said at least the motor is not reving up and down anymore every second or so, which you can feel in the steering wheel. but thats not true, everything was exactly the same. talked with him a bit more and he now says its the compressor and all cars are a little bit different lol.......!1! I wasn't getting too upset because i can't get too upset for health issues and i knew the outcome, i talked to him for like 5 min stressing that he needs to get tesla notice there is an issue and to report it as serious problem for buyers. He also said you know if something wasn't working they would change the part but since its ONLY a bit of sound...... they won't change parts..... Anyhow, continuing with the sale of the car. Really looking forward to a fix from Korea and what they have to say...
