Don’t do a driving history reset on a road trip….
My standard range-o-meter is about 289 miles. A few hours into our long haul from San Francisco to Twenty Nine Palms, we left the charger with 80% charge and I reset the estimater for fun. About 10 minutes later, we got a warning that the ford maps trip was being updated because of a change of battery range….. it was 127 miles now. Ouch. Restarted the car… no change. Went to a charger, charged it back from 72% back to 80… still 130 miles.
I know there was more and I knew what was going on. It was estimating range based on my wife’s heavy foot onto the highway and a few minutes of driving at 76. But I didn’t trust that it wouldn’t end up with weird errors and it made us nervous. Recharged in Tehachapi. The next day, recharged at a new Rivian Adventure Center and finally the guess meter was updated to real world.
