My 2017 EV+ has about 20,000 miles on it. For the past six months the range has been dropping. Now, in the last couple of weeks it has started dropping faster. Today, my Level 2 charger brought me up to 41 miles. I went to the nearest dealer and was told that next Tuesday was the soonest they can take a look at it. (Today is Thursday.) I juiced up on their Level 3 charger before heading back and it only took me up to 39 Miles. Since the Level 3 DC charger did no better than the Level 2 AC charger, I am guessing this is a battery failure and not a problem with the OBC. It's hot in Texas in the summer. I believe the air cooling of the batteries is just not enough for sustained 100+ degree weather.
Before I meet with the dealer on Tuesday, I am interested in what other might suggest I say. I'm 3 months from the end of my lease. Should I press for battery replacement or ask for the lease to be terminated sooner. Any other advise will be welcomed.
