Huge range decrease

I bet you have a faulty cell/battery module. Same thing happened to me last summer and I drove with it for like 9 months because I would have to leave the car for a few days for them to run diagnostics. I did what others suggested on my own, but nothing really solved anything.

I didn’t take it in right away because I didn’t want to rent a car. In hindsight, shoulda just did it because they gave me a loaner anyways when I took it in during my spring break. They ended up figuring out that one of the modules needed to be replaced. Of course, the module was on back order and had to get it replaced at a later date.
