HV Range error, HV range and total range estimates of a 1,000 miles are common now.
Honda PR says the HV (gas) range is determined by past driving style, which apparently means that it is based on effective (lifetime?) miles per gallon.
If you drive primarily EV, you may have a HV (gas) range that is between about 500 miles and 1,000 miles after each fill up. Apparently there is some "truth" to the number in that it could mean that you will only fill up every 1,000 miles, or that a full tank will last you 1,000 miles based on your current driving history.
The problem of course is that many of us buy a PHEV because we like to drive EV when possible, but on occasion need to drive long distances. On those trips, we could care less what our effective mpg is, only how are we doing based on the gallons left in the tank (combined with any EV range on hand).
This topic has been discussed quite a bit at the inside evs honda clarity forum. There is a push over there to post a "ticket" at the Honda owners site. Unclear if owners can put enough pressure on Honda to change the Clarity software to read a reasonable prediction of EV and HV range based on remaining batter charge and gallons in the tank.
The Chevy Volt far more reasonably reports effective lifetime mpg (a useful number to know in the background), but then it reports predictions of EV range and gas range which are close to reality.
Unclear why Honda chose the nonsense route for the HV range and thus total range too. Some think it is a mistake or bug, or just trying to be cute (because 1,000 mpg is common now among Clarity PHEV owners). Unclear why Honda refuses so far to acknowledge or address this problem.
