I own a 2016 Model S with a 70kWH battery. In the "Profile" section for my car on the MyTesla.com website, I am offered a range upgrade that states "20% Range Increase" and also includes unlimited supercharging for $3,250. There are no specifics or qualifications provided about this offer so the assumption is that a 20% range increase would give me at least 40 additional miles per charge (even at 90% charge limit). However, when I called Tesla I was told that the offered range increase would only provide 15 additional miles of range for my vehicle, which is only about an 8% increase, far less than half of what is promised to me on my "Profile". I sent an email to Tesla stating that their promise of a 20% range increase can be considered false and misleading advertising and I feel it actually borders on fraud. Tesla responded by stating that the 20% range increase applies to owners who currently have a 60kWH battery and are upgrading to the 75kWH battery. The 60kWH battery was not even an option available to me when I purchased my Model S! Tesla must know this fact because my "Profile" on their website clearly shows that I have a 70kWH battery now, not a 60kWH battery. As a minimum, the offer should clearly explain that the quoted 20% increase applies only to those who now have a 60kWH battery and that the increase is 8% (15 miles) for those who now have a 70kWH battery. For a fee of $3,250, I feel this is exorbitantly expensive and a terrible value for the money. Don't be tempted by this grossly misleading offer!
