I received a recall notice for my 2018 Chevy Bolt and my complaint is in reference to that. It is not a new issue. The remedy suggested by the recall notice is completely unrealistic. To use the car, I have to charge it overnight when I am sleeping. As is the case with almost every other Bolt owner, my charging station is in the garage. So it's unrealistic to (1) avoid depleting below 70 MPH range, (2) park my vehicle outside immediately after charging, and (3) avoid charging the car in my garage overnight. I just want to make sure GM does not escape liability if there is a problem and I did not follow these unrealistic guidelines

The first year of the lease, the main computer began to fail and the entire screen would become black, with the entire car intermittently losing power on the freeway. The computer was replaced. Later on, the blind spot sensors became erratic, but this is likely due to a shoddy repair by the dealership after someone rear-ended the car. The primary concern is the powertrain. The battery range decreased by nearly half while driving, which would have been dangerous in a remote location. There seems to be an issue with the battery modules on the 2018 chevrolet bolt.
