So I went to our Chevy dealer for the @7,500 mile rotation, yesterday July 31, 2017. I already reached 30,000 miles and this is the 4th time. Then told me that there is a software update for optimizing battery and making better sensor interpretation for use in braking or ACC. And so signed them up to do the recall at GM's expense. It wasn't very clear to me about their explanation as to what the recall really did, as the report that I got from them was only about the tread on my 4 tires.
Anyway, every time they update the software, they needed to run the ICE to test that everything is alright. And so what I piled up for the most number of miles driven without gas has been reset to zero again!!! There goes my VoltStat score. I would have already hit 25,000 miles or more without gas (except FMM) if our dealer isn't running the ICE every time a software update is done on my 2017 Volt.
Anyway, the update seemed to give me better MPGe scores at speeds of 70-80 mph compared to my scores before the update. I only used to get 84-90 MPGe when doing 70-80 mph, but now I m getting 95-115 MPGe. Moreover, the ACC doesn't seem to be as flaky anymore from my drive yesterday.
Anyone else notice about the latest software upgrade?
