    Anyone else have this issue. I was driving around 40mph and the door just opened by itself. At a red light ibwas able to open it and close it.

    This happened after receiving the new firmware.

    Anyone else experience this problem? Should I contact tesla about this issue?

    Three possible options, none of which have anything to do with the firmware (the doors are mechanically actuated by pulling on the handles).

    1) The latch failed
    2) You didn't fully close the door
    3) Aliens

    It's hard to admit to ourselves, but human error is the most likely cause here. I'm not accusing you of being an idiot — everybody knows how to close a door, after all — but you also know that Model S doors require a bit of force to fully close. You know you closed the door fully, or at least you think you did — our brains are great at filling in the details of stuff we weren't really paying attention to with what fits our preconceived expectations (this is what makes eyewitness testimony so unreliable), and something as simple, repetitive, and non-thinking as closing the door gets filled in every time it happens as expected.

    I'd not worry unless you're noticing parts of the latch that seem worn or damaged, unnatural movement of the door when opening or closing, looseness when closed, or (obviously) it happens again.

    Or it was aliens.

    Very common problem, have it checked at service center asap.

    Isn't the door unlatching every time the handle extends a standard failure of when one of the internal switches goes bad or a wire breaks. I'm surprised the NHTSA hasn't required a recall.

    Could be the control module or wiring. I've had that fixed a couple of times.

    Highly doubt any of the reasons you stated. The car was fine and then it opened automatically and the warning came on saying door is open. The waening didnt go away until I open and close the door properly. So this rules out not closing properly before. Latch might have failed but I was able to still use the door fine after I closed it properly.

    I am just worries if this is going to be a common thing. Ill ask the service center to look at it. But since this is the first time, it might be hard to reproduce at the service center.

    I have seen at least another thread on this happening to someone. I will say that sometimes I think when we close the doors getting out it doesn't sound like it was closed hard enough but hubby is able to lock the doors and says their closed. But never had it open on us while driving.

    The interior handles on the front doors electronically open the door. There is a mechanical override built in if you continue pulling them all the way.

    So an electrical glitch or firmware glitch can cause the door to open.

    I had this happen to me at an intersection, I was waiting at the light and there was a loud unlatch sound and an alarm chime. Scared the daylights out of me. I looked at the error and it said "Driver Door Open". The door was fully sealed and locked prior to departure, and I had been driving for about 15 minutes prior to the door opening.

    I called Tesla Service and they sent a ranger to replace the offending door handle a few days later in my own driveway. It took less than an hour to get the repair done.

    Definitely call Tesla, they will replace the handle for you. I have never had an issue of this nature after the repair.

    Good luck!

    I had a loaner car earlier this week. It happened about 50% of the time when the doors unlocked on the front passenger door. There must have been something in the door handle mechanism that was indicating "open" and, as soon as the door unlocked, it did.

    I was happy to give that car back. On an unrelated note - didn't Elon say way-back-when that loaner cars would be the newest, best-optioned cars? Every time I get one it seems to be in rougher shape than the previous. Besides the door problem, this one (P85+ with only 15k miles on it) had severe backlash in the DU and was extremely noisy.

    Every loaner they've given me has had *something* wrong with it. Always minor things though.

    If the door handle is failing/out of spec, when it extends (car placed into Park) it can hit the microswitch and unlatch the door. A known issue, especially on older S.

    Service center told me to bring it in. They will replace the handle. At least that is what they told me.
