I knew something was wrong once I charged to 100% (i drive it almost within 30 mins from full everytime) and noticed it didn't even have 200 miles of range. I normally get 250-280. Sometimes even seen close to 300 before any of those software upgrades. Pamper the car and drive like an old fart. Averaging 4.3-4.5mi/kwh. Brought it to the dealer after 2 months of holding back due to this corona virus BS. I did not want to be without a car (esp EV) for an unknown period of time but I had no chance but to schedule. Now I got confirmation that they will replace the entire battery. I am very disappointed as the dealer didn't offer any credits for uber/lyft or even a rental while I waited for 2 hours for them to "diagnose" the problem. I told them that you're not going to be able to fix it today as there's a major battery problem. Now I'm stuck paying for this thing (thank God it's leased) that can't do jack for me. And who knows when I'll get it back. I will never get another GM vehicle ever again. If anyone had this problem before, can you let me know how long does it normally take to do a battery install? I've had a 1st gen Nissan LEAF and they did it in half a day. Thanks and drive safe everyone.
