I hade the software update 3 weeks ago and was led to believe it would give me 80% of original mileage which would be about 200 miles. My first full charge stopped at 136 miles. I spoke with dealership and they said the battery needs to "Learn" your driving habits. My response was, It did not need to learn my driving habits when I first purchased it." They asked me to give it time. I now only receive a max of 127 miles- for a full charge. Anyone else having this issue?
