Anyone had FWD phantom obstacle fixed by SC?

    My driver's side FWD gets a red bar, phantom obstacle detected if it sits in the sun for more than 5-10 minutes. The SC is claiming that it's a design limitation and the doors just won't operate above a certain surface temperature.

    Obviously, that's simply not true or thousands of people would be having the same issue. Had anyone had chronic FWD problems that has actually had this fixed? It happens to me multiple times a a week, sometimes multiple times per day.

    I love my car, but I'm seriously considering starting a lemon claim. This will be the fourth visit for this issue, twice they claimed no trouble found until I showed them how to reproduce, finally they replaced the FWD sensor, but it was right as we went into fall and the problem only popped up once or twice during fall/winter. Now, in the peak of summer it's pretty much a daily occurrence.

    Service center replaced the sensors in both of our doors for that exact same reason. Haven’t had an issue since the beginning of summer.
    They did state it was a known issue with darker colored model x’s.

    Yep, I was the one who had this exact issue and just like you went through fall/summer before they could consistently reproduce it. I have started a thread about it before but most people don’t seem to have the issue or not as consistently bad as mine. It was a Midnight silver.

    They’ve replaced the sensors numerous time, the tripod assembly etc., and the last resort replacing the whole falcon door. It only happened on driver side but it started showing up on passenger side during the buyback.

    Long story short, Tesla ended up buying it back and I got a new one in pearl white. The new one is not without issues though!

    Interesting, I'd read through a few of the threads about it. I saw a couple fixed with door replacements and sensor replacements. I guess I can insist they replace the sensor again. NC lemon law is 2yrs or 24k miles and I'm just over 22k at the moment. It was a demo with 7700 on it at the start, so not sure if lemon would take that into account.

    I think I've had most of the standard MX problems, but still happy with the car overall. Mine's blue, so on the darker end of the spectrum.

    I had that same problem on the right side, although I did not correlate it with temperature. My Service Ctr knew about the problem and fixed it correctly the first time. Have your guys check with them in Austin TX.

    Call BS. I had the same issue, it was bad enough to enter into calibration mode on occasion. I had to take it in several times but ultimately my sensors have been repalced which 100% resolved the problem.

    Seem like a sensor and a software issue... or the tolerances in the sensors need to be re-engineered...good luck...

    So, as a followup, the SC added an oversized butyl patch to the driver's side FWD to help disperse the heat at the sensor and so far, I've had no phantom obstacles.

    Before 5 minutes in the sun was enough to trigger it and I've gone hours now without a problem. We'll see if it's a lasting fix.

    Do the sensors still function correctly? Ie still detect obstacles when there are obstacles?

    I think at one point they screwed with my sensors so that while the sensors didn’t detect obstacles under the sun, it didn’t even detect me standing right next to the door.

    Yes, I park in a fairly tight garage with the wall on the driver's side and it's working properly.

    I had a similar issue and they replaced the sensors, issue persisted. A mobile tech came out and replaced the black plastic piece towards the bottom outside of the FWD and no more issue.

    I also have this issue with my midnight silver metallic MX, they recommended a soft reset. I will be keeping an eye out for this.
