#Chevy volt range by year update#

GM dealership would not reverse the update and recover my original 10.3kwh full charge capacity. ( they told me it was a liability issue and the original factory firmware was not available anymore ) …… 🤕☹ This method works 100% because I successfully performed this on my 2012 Chevy Volt car after a GM dealership reprogrammed my HCPM2 module and subsequently I lost 1.2kwh per full charge. Now charge your Volt…… your battery range will come back to the original 10.3kwh ( or whatever it was before the GM dealership HPCM2 firmware update ) per full charge range. Once you reset the HCPM2 module, turn the Volt off and back on again. 1955 was the first year for the optional 265ci Small Block V8. As Chevrolet tooled up for the Task Force platform, some factories continued to produce the earlier design as the 1955 1st Series, while the new design was produced as the 1955 2nd Series. ( You need to scroll down the various menus to find this “reset” option ) GMC continued to offer 12-volt electronics as an option. Next plug in the VXDiag programmer into your OBD2 port ( under the steering wheel ), run the downloaded program ( from VCXDiag website ) and “reset” the HCPM2 module in the menu. The 2018 Chevrolet Volt plug-in hybrid offers impressive range, surprisingly good driving dynamics, and a healthy dose of standard technology.

My car is a 2013 with 102k miles, 85k of which are EV.'ĭownload the free software to run the VXDiag programmer into your laptop running Windows.ĭisconnect your 12 volt battery, ( in the trunk compartment ) and swap in the used HPCM2 module ( module is located under the passenger front seat ) it is easier to remove the 2 torx bolts and lift the seat out of the way to swap the HCPM2 module out. I want to get this taken care of but my fear is they will take even more capacity away from me in order to get the message to go away. Then yesterday, when starting the car the engine was racing and the Propulsion Power Reduced warning came on with the car just sitting in my garage. Unfortunately over the past month or so I have been getting the Propulsion Power Reduced message pretty regularly while driving normally on level ground.

'So about a year ago my car was reprogrammed for an unrelated issue but the affect of the programming is it dropped my usable battery capacity from 10.4 kwh to 9.4 kwh.

I have given up on the whole thing and will just live with the car as is. Dealerships have been very unhelpful with the whole situation and wont do anything about the reduced range or the PPR messages. Here is a post i made about it on 3/8/18. BRAIN POWER Up to 53-mile battery range Up to 420 miles of total range with a full charge 1,100 miles between fill-ups How does it work How long. Yes, the exact same thing happened to me and unfortunately I have been living with it and the PPR messages for well over a year now.
