I have the same issue though not nearly as bad as yours. I have a 2012, P85 with 71k miles and have had Tesla 19" wheels that I had powder coated black.
I just posted to another thread that dealt with this. I asked Tesla to give me a definitive answer or cause for this and Engineering mentioned my powder coated wheels. Does your car happen to have powder coated wheels? They believe it may be that the contact area between the wheels and the rotors does not allow heat transfer/dissipation from the rotors to the wheels and thus cuases heat build up.
I am on my third set of rotors.
Until I saw these posts I was certain that it was just my car because Tesla said that they had never seen this before.
So, I have a couple of options:
- Take the wheels off and grind the powder coating off on the rotor contact area then put them back on and hope that this now allows the wheels to be heat sinks for the rotors.
- Buy a new set of 19 wheels and see what happens.
Option 1 is the cheapest fastest and almost the least hassle since I can do it at home. If that is the problem, I'm golden and the brakes should almost last me forever as I had originally thought. However, if that is not the answer and the rotors warp again, Tesla will not comp me the rotors again. I will then have to spring for new rotors and pads as well as then get the new wheels.
Option 2 costs me about $12-1400 depending on what kind of discount they are willing to give me for the hassle. They can come get the car, do the work and we see what happens. The thing is that if it happens with the new factory wheels, they would now have to come up with some other suggestions and from now on and it would be on their dime since I also purchased all the extended warranties and would have followed all of their suggestions.
I would like to hear your thoughts and suggestions.
