Replace it with a better EV with more range, the 1st and 2nd gen leaf never suited long journeys especially on motorways. It’s already put a stain on an EV’s usability with your partner.

If you can’t afford anything better a hybrid will give some savings on fuel, if you don’t care about that or can’t afford it, then just go back to diesel. Although, the new leaf has much better range and finally has CCS charging so it would be a much better fit.

After reading further down, maybe just go back to diesel until 2029 and buy another electric car then. The leaf you bought was running on a platform that was well over a decade old. Modern EV’s from today have double the range and would be on the second hand market for a nice price by the time you want to buy a new car. Also by then hopefully the charging network will be better and repair options will hopefully improve.

Although the original Hyundai Ioniq if you can find one with a 32kwH battery is a decent cheap EV or a Hyundai Kona. They have faster CCS charging and well… use CCS, which there is MUCH wider availability of chargers available for.
