IONNA tops JD Power US public charging rankings in debut year with 807 out of 1,000 score
By Eve
IONNA, the automaker consortium backed by BMW, GM, Honda, Hyundai, Kia, Mercedes-Benz, Stellantis and Toyota, scored 807 out of 1,000 in the 2026 JD Power US Electric Vehicle Experience Public Charging Study, ahead of Mercedes-Benz Charging Network at 797 and Rivian Adventure Network at 755. The network, which operates 1,375 ports across 150 stations, uses Alpitronic hardware and proprietary software, with CEO Seth Cutler citing first-attempt success rate as its reliability metric. JD Power noted the newer automaker-backed networks scored more than 100 points above segment average in ease of charging, charging speed and charger availability.
Why it matters: The strong debut validates the amenity-rich Rechargery model for procurement teams evaluating site design standards, whilst IONNA's rapid climb to the top of reliability rankings may influence OEM partnerships and hardware selection for CPOs competing on driver satisfaction metrics.
