Not sure if this has been talked about before, but I wanted to share a recent Technical Service Bulletin from Tesla that fixed my automatic trunk. There is an addition of an O Ring now from Tesla to the struts of the trunk of the Model 3. This O-Ring prevents water from entering the top of the strut causing intermittent opening issues. Once you press the button, either inside or out, the trunk would only open 30-50% of the way and beep three times. This repair was done by the mobile technician and took about 20 minutes to complete.
