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.

2014 Tesla Model S Owner Comments

problem #1

Model S

  • Automatic transmission
  • 55,000 miles


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.
