Liftgate intermittently stops working. More than 4 months gone by and this is just the first year of ownership. Mobile service checked it out and acknowledged the problem and recommended bringing in for service in Oct 2021. The service center in Sunnyvale, CA did not even look at the car but asked to reschedule an appointment in Nov 2021 when the suspect part, the actuator, would arrive. No Actuator in Nov 2021, so service is rescheduled for Dec 2021. No actuator in Dec 2021, so service is scheduled in Jan 2022. In the meantime the liftgate opens by itself. The actuator is ordered anyway. Jan 2022 Liftgate stops working again. Service date is now long gone and new date is fixed for Feb 2021. By the way, the liftgate opened by itself last week. I am not amused by this quality crap. The worst of all TESLA Service sucks the most. Why should anyone tolerate this ? Elon and team, you have a crappy service team and worst of all their knowledge level sucks. I am still hopeful but we all have our limits.
