I'm hoping that my battery will be covered under the warranty. I'm sure they will run tests on my S and will report what they find out. My work commute is about 150 miles with some hills. I used to be able to make the trip in one charge, now i have to charge 15 mins. Antelope Valley to Ridgecrest, luckily they have 2 supercharging stations along the way.
Having my S for so long, i did start to notice connection issues to the supercharger. I received the red ring of death, I think that's a hardware link error. I have to reinsert and it starts working as long as it goes in straight without pulling. Funny thing is there was another S that was old as mine and had the same exact problem. Poor guy tried all the stations in lone pine and then tried inyokern with no luck. I told him that he should try reinserting and make sure it doesn't pull the cable. This time it made a proper handshake and started charging properly. Definitely a trip to service center is needed for both of us.
