Hi,have a Hyundai Kona being replaced in January (hopefully) with Renault Scenic ev,realistic range in winter about 260 miles using heating etc so no range problems although my longest journeys tend to be 200 miles return,have had multiple problems the past 18 months with the 12 volt battery where I get into the car and everything was dead electrically.
this involved 5 call-outs from RAC who replaced 12 volt battery each time and it immediately went no bother,however it was also back to main dealer 3 times to try to discover what was causing the problem,each time I was just told “it’s sorted” until several weeks later same thing would happen.
I finally found a fix if it can be called that where I bought a little portable battery booster and next time there was absolutely no power I just connected the booster to 12 volt battery and power immediately comes back on for another couple of weeks,can only assume it’s a temporary glitch between 12 volt and main battery.didnt need those 12 volt batteries replaced after all.
other than that it’s been a great car to drive and I’d have had another Kona but the Scenic has more room for my needs..
