The battery is the same as the old battery. The Volt needs to re-learn your driving style to estimate the EV range and that battery usage. The 9-9.9 KWH will change as you drive the Volt, make sure that you are keeping the ball in the middle, and watch your driving style. The ambient temperature also affects the KWH, as the temperature drops the Volt will need to work harder to keep the lithium battery at the 87 degrees for driving.
I apologize about the noise in the Volt. We would recommend that you have the dealerships Volt technician take a look at the vehicle. They would be able to see if it's normal or if there is something that needs to be repaired.
If you have any questions, please do not hesitate to contact one of our Volt Advisors at 877-486-5846. Volt Advisors are available seven days a week from 7 AM to 12 Midnight, Eastern Standard Time.

I was actually looking for a video to send to you to try and help you out, but it looks like you were able to figure it out. I will definitely pass the suggestion along about having this information in future owner's manual.

Hi Folks; Love our Volt! Our wishes though would be for more electric range and a power adjustable front seat. We live in the country 30 miles from town, our normal trip is 75 miles between charges. Our local driving averages about 60 mpg which is great as our electricity is from solar and wind. We drive to town two to four times a week which includes 10 miles of gravel (20 miles round trip). The Volt is doing well ride and handling on gravel is great. Electric range is reduced on gravel a little, only problem has been the low air dam wants to grade the gravel center berm requiring driving on top of them.
