CarComplaints.com Notes: The Model S has a 5-star safety rating and scored a 99/100 in consumer satisfaction from Consumer Reports. Even when a problem with battery fires popped up, Tesla promptly responded with an over-the-air-software update and military grade titanium. Impressive. Still it's too early to tell how this car will hold up.
My 85KWH battery is only delivering about 50 KWH or less over a 10 day period between charges. Even assuming that the available energy is only 81 KWH, I am clearly getting less than 70% of effective battery capacity. My daily commute currently gets only about 120 miles from a charge, instead of about 250 when I bought the car.
I spent months texting and emailing with a Tesla engineer. I provided ample photographic proof of the battery leakage from the dash statistics, but he insisted the battery capacity was about 98% of original, and refused to replace the battery under the warranty.
Interestingly, I didn't notice the problem for a long time because I used to have a convenient at-home charging system, and charged the car every few days. However, since moving to a smaller house where charging is inconvenient, I usually drain the battery from 90% to about 10% between charges. That's when I realized the problem. My guess is that many thousands of others have the same problem, but don't appreciate it because they are charging at shorter intervals.
