We love our 2020 Nexo. Live in South Orange County and have had no problems refueling. Put on 15,000 miles in the first year.
We picked ours up from Hyundai in San Jose then drove it down the 101 refueling in Santa Barbara.
Excellent vehicle. Offers much more comfortable rear seats and trunk space than the Mirai.
That said, picking up a 2022 Mirai Limited next month for a 2nd hydrogen vehicle. But won’t be using the rear seats much so it will be ok. Excited for the new Toyota Teammate tech.
