This evening I experienced an odd problem, for which I called Tesla Roadside Assistance to log the issue. Returning to my parked car with some purchases, I opened the motorized rear hatch using the manual switch under the chrome trim at the bottom of the hatch. It opened normally, I placed my purchased in the trunk, and I pressed the closure switch on the right underside of the opened hatch, as I have done many times before. The hatch appeared to be closed, but upon entering the car I noted that the dash display indicated that the hatch was open. Pressing the rear hatch button on the fob twice rapidly produced a triple beep alert sound on the car's audio system, rather than opening the hatch. The same alert sound occurred if I tried to manually open the hatch. Pressing down carefully on the hatch suggest that it is perhaps 1/8" higher than it would be if fully closed, although to the eye alone it appears fully closed. It was at this point that I called Roadside Assistance. I successfully rebooted the MCU, but that had no effect upon the problem. The hatch remained in this state in spite of repeated attempts to open/close it manually and with the fob. I did not use the iPhone app or MCU displays to try to control it (an unfortunate oversight on my part). I took the opportunity to report at the same time that I have had to reboot the MCU from 1-3 times daily, with few exceptions, for the past two weeks. My vehicle has also frequently lost LTE connectivity on multiple occasions for extended periods of time during the same period, a new experience. I was able to drive the vehicle home, though there was a small initial popup in the dash display along the lines of "Rear hatch open, proceed with caution," and an intermittent beep tone was played for a minute or so. When I parked the vehicle, the door handles refused to retract when I exited the car and pressed the center button of the fob. However, when I returned to my locked garage later, they had retracted (presumably doing so after the conventional delay time when one walks away from the vehicle without using the fob to lock it) and they presented themselves normally when the fob got within range. I used the MCU to turn off the power of the car in case it tried to activate the hatch while unattended. I removed my purchases by lowering the driver-side rear seat and pulling them out of the trunk area. When I had crawled into the trunk during the early part of this episode, thinking that I might be able to open the hatch from inside, I did not note any emergency trunk release switch, such as is present in the frunk -- I was a bit surprised at this (but may have overlooked it). Has anyone else experienced a similar problem? My thanks in advance for any helpful observations (this note is written in a spirit of sharing helpful information for those like myself who are eager to learn as much as they can about the Model S, and hope responses will be written in the same spirit). I still consider my Model S a splendid vehicle which I feel fortunate to own and find a delight to drive.
