When I first got my Clarity in January I would charge the battery and the next day the battery at fully charged 100% would always be around 55 miles. I was thrilled. Then all of a sudden a few days ago it dropped to 43 miles fully charged. This has happened over the last 3 charges. Have no idea what happened. The weather here in Palm Springs hasn't changed much since I bought the car 3 months ago. Average temps are around 90 in the day and 75 at night. The only thing that has changed was I drove the car and drained the battery to zero level. After that happened this is when the problem started. Has anyone else had this weird fluctuation?
