2017 Chevrolet Bolt EV electrical system problems

I brought the car to the dealer on 2 separate occasions with concerns of a faulty battery. The battery suddenly stopped charging fully. However, I was told by the dealer twice that the battery was functioning properly and there was nothing they could do. I opened a claim with GM regarding this incident, asking them to replace the battery, since it was still under warranty, and there was clearly an issue. After months of back-and-forth, GM closed my case stating it was 'normal depreciation' of the battery.

The vehicle was towed to capitol chevrolet (905 capitol expressway auto mall, san jose, ca 95136) where it was diagnosed that the battery needed to be replaced. The battery was replaced. The manufacturer was made aware of the failure and referred the contact back to the dealer. The failure mileage was 4,193.
