I had the opportunity to review the P85+ because my car went in for service. One of the reasons for the service was that the dash had issued the warning: “Service Tire Pressure System…Contact Tesla Service.” This warning came up repeatedly on my long road trip down the coast during long stretches of freeway driving.
Since I was far away from home I called the 800 number to speak with a Tesla person. He said it could be the tires or the warning system itself. I looked at all the tires and they looked fine. I have to confess, I do not carry a tire pressure gauge and did not venture to a gas station, my check was solely visual. The light came on and off about six times. When the warning showed up it was on for 30 miles or so. From the forums, it looks like several people have had problems with the tire pressure systems. During the service, they replaced the TPMS module and repositioned it.
The Roadster also had physical sensors. The car also told you the actual tire pressure in a screen readout. The Model S does not have a numerical readout, simply a warning if the pressure is incorrect. I hope that the software will eventually have a numerical readout, as I am not particularly prone to noticing low tire pressure.
I also hopefully had my last door handle replaced as my doors like to open by themselves. This time, my driver side rear door handle has been replaced. I hope this problem is fixed for good.
The service also included installing some new rear window regulator clips. It appears that some people have had issues with the rear windows remaining open and these small parts will solve that issue. More detailed reports of this problem can be found here. In the past I had problems with my Toyota windows after putting a small strap through the rear window while driving but I have not had any problems myself with my rear windows.
The service department also tried to reproduce my intermittent noise and bluetooth issues. Occasionally, often but not always near power lines, my car makes noise similar to tv or radio static. The noise can be quite loud, and seems to be more frequent with passengers in the rear seats. I have tried many times to drive over the same route to reproduce it consistently but have been unable to. During my test drive of the P85+ I also experienced this same noise but it was quieter than my own car but not less frequent.
I have also had intermittent problems with the bluetooth connection to my Iphone while listening to music or audiobooks. The connection fails and is difficult to reconnect. Rebooting the Iphone does not solve the problem. I had to reboot both the car and the Iphone to get the connection back again.
Unfortunately, since both these problems are intermittent, Tesla could not reproduce them and neither can I in a consistent manner.
