I bought a Bolt LT about 4 months ago in the Lower Mainland. Slowly getting used to it. I was told by the salesman that I would get about 390 kms on a full charge. I felt great, when charging, that I was getting up to 515kms. Yes not a typo. 515. Then the call from my GM dealer informing me of a recall. He said I needed to get the Control modules calibrated. After the recalibration I now only get 425 kms on a full charge. I know it is better than 390 kms but 515 was great. What gives?

Drive a few charge cycles and it'll probably come back up.
The recalibration has caused some wonkiness in some owners'
Guess-O-Meters.

If you were paying attention to the kWh/100 km number that that range quess was calculated from, you might be able to tell if your battery capacity has actually changed.

Gern you really have to stop flogging a dead horse!

I find the DIC very accurate at predicting mileage based on historical and current driving styles. Developed by people much smarter than you or I. I for one have no issues with the information that is presented to me on all displays.

Pironside ..I too have taken a range reduction after that recall.Was really happy with the car but now im a little botherd by the lowered range and im not sure if you noticed but i noticed a loss of power after the recall too..Been back to shop and no problems found but they did replace the outside temp sensor and said drive a few cycles but its been bit now and no change.

I have a similar question. My GOM range has definitely taken a hit since Houston got into air conditioning season. Typical range has reduced from 240 to 205. I had been simply chalking that up to climate control needs. But this week is temperate and rainy, and range is still about the same (instead of normal non-a/c 4 mi/kWh it is more like 3.5 mi/kWh).
A few weeks ago I allowed the over-the-air update to proceed. Is there some relation?

I think he (and I) use the term "Guess-o-meter" to underscore the fact that the range information really is only a guess. It's a pretty good guess as long as the driving conditions don't change, but it really has no clue about what you're going to encounter before you actually drive the next xxx km that is displayed as the range. Speeds, temperatures, terrain, winds, traffic - they can all have a pretty significant effect on whether you'll actually be able to achieve that predicted range.

I find that using the term "Guess-o-meter" is a good way to remind everyone of that.
