I just took my GV60 on a highway trip from NV to CA and was shocked by the terrible range. I usually get around 3.4-3.5 mi/kWh, but today I barely managed 2.5-2.8 mi/kWh! Even with eco mode and minimal charging wait times, I had to stop twice to charge. Has anyone else experienced this kind of drastic drop in range, especially in colder weather or rainy conditions? I'm wondering if something's wrong with my car.
