- IONNA scored 807 out of 1,000 in the 2026 JD Power US Electric Vehicle Experience Public Charging Study, ranking first among US fast-charging networks with 1,375 ports across 150 stations as of the day of publication.
- Mercedes-Benz Charging Network placed second at 797 and Rivian Adventure Network third at 755 — the first year all three were eligible for JD Power awards, and all three swept the top spots.
- IONNA is backed by eight automakers (BMW, GM, Honda, Hyundai, Kia, Mercedes-Benz, Stellantis, Toyota) and runs "Rechargery" sites that pair DC fast chargers with canopies, restrooms, food, and lounges.
- Overall DC fast-charging satisfaction rose 12 points year over year to 666, with charger availability up 27 points, safety perception up 18 points, and charging cost up 18 points.
- Failed charging visits fell to 12% in the most recent quarter — the lowest level recorded since the study began in 2021, down from 14% a year earlier, meaning roughly 1 in 8 EV drivers still couldn't charge.
- Public Level 2 charging satisfaction dropped 12 points to 595, driven by more reported problems with payment and starting charging sessions, moving opposite to the DC fast-charging trend.
- IONNA CEO Seth Cutler told the outlet the network uses Alpitronic hardware with in-house software, measures reliability via first-attempt success rate, and benefited from launching after competitors: "we've been able to learn from others."
Why it matters: Eight automakers pooled resources to build IONNA, and in its first year of JD Power eligibility it beat every other US fast-charging network — suggesting that purpose-built, amenity-rich sites with newer hardware are pulling ahead of first-generation operators. The 141-point gap between IONNA's 807 and the segment average of 666 quantifies where reliability gains are coming from, while the 12% failure rate shows the industry still has roughly one broken visit in eight to close.
