Two weeks ago I had to take a 260 mile round trip so I max charged my S85 to an expected 270 miles. When I opened the garage in the morning the dash read 259. Since I needed every mile and was going to use every trick to make it without charging I was bothered by the 11 mile loss. On the way out I called Ownership and was told that my car only charged to 95.3%, not 100%. There were some explanations which were less than convincing to me, but I thought it might be a glitch.
After I returned I supercharged to max again and got to 261. Again, I called ownership and was told they had investigated, and everything was fine, but my green bar still had about an eighth of an inch of gray. No one was able to explain this discrepancy.
Today I have a 260 mile round trip and supercharged last night to 262 and full. When I got home I plugged in to a 220 outlet. I woke this morning to a disappointing 258. The ideal was 292 in stead of 300. I unplugged and plugged in again. It immediately went to 297. It now tells me charging is complete with 294. I have 12,000 miles on the car. If the ideal range is 6 miles short, have I lost 2% of the battery in 12,000 miles? I know there is supposed to be some over time degradation and it's part of the deal.
Anyone else experience similar problems (choose your word: event, happening, occurrence--because it may not be a problem.
