Headed home and planned a SC stop for lunchtime. I was 95 miles from home with a rated range of 93 miles so I stopped at the Newburgh SC. Problem: I wasn't able to get a charge. Alert said "check charger power" I tried 3 separate superchargers out of the 6 units there. Each time the voltage would go up to about 319 then back down to 200 or so then back up to 319, and then back down to zero and stayed there. I tried another SC unit twice--same readings. I called Tesla Service and after being on hold for about 15 minutes I spoke with a representative. She believed it may be a supercharger issue though I did mention two other cars were here charging and did not have a problem. So she asked me to try another one and after the X charge and left unit 3B I plugged in. No change. She asked me if Newburgh has a service center and I replied "no". I'll give her a break but figured she should have the service center info right in front of her, right? I mentioned Mt. Kisco is probably the closest and she checked and agreed. Gee thanks. It was about 48 miles away so I headed to Mount Kisco. When I arrived I spoke with the service representative who was expecting me and he had me hook up to the destination charger. I didn't realize on the way that they do not have superchargers there so that wasn't really much help. The destination charger worked fine ,I left it on there for about an hour or went to get some lunch. I probably could have gotten home but why chance it? I charged enough to get home without sweating too much about range. I arrived home with 7% charge left. So destination chargers and my home14-50 works just fine. I will go next week to the supercharger near my house in Syosset which is also a service center and see if I still have this issue. Obviously I need to know if there is a supercharger problem regarding this car. I'll call Monday and see if someone can look into it. I will keep you updated. I am wondering has anyone else had a problem similar to this? Remember each time I plug the supercharger in the voltage would go up to about 319, come back down somewhat back up all the way and then back down to zero. I would also get alerts popping up "pull over for your safety" and " unable to start car" as it seemed the computer was getting confused. I have had the S for 3 weeks now and I have super charged 4 times with no problems.
