I just had my 2010 Serviced at home (I offered to bring it to the SC as they have their own equipment and expertise available, but they assured me it would be fine.) The guys took out the PEM and cleaned it out. They told me it would be $270 for the 12v battery (in addition to the $600 for the service and $100 for the Ranger visit) (I told them I would replace it myself) and said nothing about the fob batteries and wiper blade. Turns out the batteries are $6.00 and wiper blade are $76.14 (included in the $600.) I wonder if you replace the batteries and wiper blade yourself if you can save another $60?
When they started to drive the car off the ramps, there was a loud bang! and no movement. We all looked at each other with surprised faces. A few hours later, they were able to roll the car off the ramp in neutral. There was no smells at all. Tesla called me later that evening to tell me they were sending a flatbed :-( and a loaner S . When the driver picked up the car, he noticed a strange smell around the battery (I could not discern one myself.)
Long story (and a week later) they returned the car and took the loaner :-( Turns out there is a known flaw in the PEM that can cause arcing between the high voltage. This in turn took out some of the battery's cells(!) and one of the battery computers (!)
Needless to say, they replaced the PEM and battery pack. Apparently the new(er) refurbished packs have ultrasound instead of conventional welds, so they are "better." Both the PEM and the battery come with one year warranty's (a very nice surprise.) My old pack's CAC was 145, the new pack's CAC is 150.
