At 58k miles my bolt started giving an error code, "service high voltage charging system". I took it to a chevy dealership and they said it was not their fault and that I had hit something that dented the bottom of the car and damaged the battery. They told me it will be $20k to replace the battery. I feel so cheated because I didn't even have an accident or anything and now my $28k car is totaled. Maybe I went over speed bumps too quickly? I am just going to let the dealership I bought it from come repo it. This has really turned me off of electric cars and I think it was a huge mistake to have ever bought this car.
