I picked up my inventoried P100D Model X that was a showroom car with 500 miles on it just last Thursday and although the delivery process itself went smooth, I had problems with the car right from the get go. When I arrived at the delivery center, I was taken to the car and sat in it for the first time. As excited as I was, I turned the car on and immediately, the first problem arose: No audio. Delivery specialist took the car around to service and 15 minutes later, it came back out and audio worked fine. I continued to inspect the entire vehicle and everything looked good except for a small nick in the drivers side door near the edge of the door. Delivery specialist touched it up and I was satisfied. I had planned on wrapping the entire car anyway. Signed the paperwork and off I went. Drive home was great, everything was functional and had my first taste at Autopilot. I was hooked. Got home, parked it in my garage, plugged it in and all was great. I couldn't wait to drive it the next day. The next day I took it to work and that's when things started to happen. First was the tire pressure monitors came up indicating 3 of the 4 tires were at 37psi. They were all at 42 psi when I picked it up the day before. It was a little cold out so I filled the tires back up and warnings went away. Chalk it up to the change in temperature.(I am in NE PA) Moving on...Later during the drive, I got a warning pop up that said "Car needs service, steering assist reduced." I thought, what now? The vehicle drove fine except that autosteer was disabled. Still had cruise control. Googled it and found many experienced this exact warning and all was needed was a reboot. I called the service center and they told me to do the same thing: Reboot the system. Pushed on brake and hold the 2 scroll wheels in and car rebooted. Warning went away and off I continued with my day. I got home that night and plugged the car in again. The next morning I got in the car and the warning came back up. Called the service center again and after being on hold for 18 minutes, someone finally answered and ran diagnostics on the car. They saw the errors and told me that the car had been trying to download a firmware update for the past 11 days. I told the advisor that I've only had the car for 4 days up to that point. He told me to check the wi-fi when I went home and see if it downloads the latest firmware. I did just that when I got home and the firmware updated successfully. I now had 2018.34.1 3dd3072. The next day I went to take the car to get the windows tinted. I dropped off the car and when it was done, my tint guy called and said that the car had no power steering. I didn't believe him. He dropped it off to me and everything seemed fine except for that "Car needs service, steering assist reduced" warning was still there. I was at work so before I went back in to work, I tried a hard reset twice but to no avail. Warning was still there. A few hours later, I got done work and got in my car, put it in drive and wouldn't you know.... no power steering. At this point I was extremely frustrated to say the least. Called the service center again and they created a ticket and scheduled a mobile tech to come and fix it. Still holding my patience at this point, I googled "Model X loss of power steering." Sure enough, there were many others that experienced this and the temporary solution was to power down the car, wait a few mins, then power back up. I did this and it worked, the power steering was back. Drove it home, parked and plugged it in for the night. Not gonna bore you anymore but after 2 more days of the same thing happening, the temporary fix no longer worked. I now can't get the power steering to work anymore and the car is an absolute bear to drive. Only positive thing I can say is that my biceps seem to have gotten bigger with the workout I am getting manual steering this car. I am beyond frustrated and beginning to second guess my decision to buy this $150k plus vehicle. Not to mention how embarrassing it was to take top level executives for a ride in my car and not have power steering. So I have an appointment tomorrow morning (9/13) at the service center that is an hour away and I am supposed to drive this car without power steering. I am not looking forward to that drive. Oh I almost forgot, there is something rolling around in the passenger side door that sounds like a marble rolling back and forth as I accelerate and decelerate. That should make the drive even more enjoyable. I'll keep everyone posted on what happens tomorrow but for right now....I HATE THIS CAR!!!
