Tesla’s Supercharger network has spent years as the benchmark competitors were trying to catch. In 2026, the competition finally did more than close the gap. J.D. Power’s latest U.S. public-charging study placed Tesla fourth among DC fast-charging networks, ending a five-year run at the top as three newer automaker-backed networks moved ahead.
The result does not mean Superchargers suddenly became unreliable or unpopular. Tesla’s satisfaction score declined only modestly from a year earlier, while the overall fast-charging market improved substantially. Instead, the rankings show how quickly expectations are changing. Drivers increasingly judge a charging stop not merely by whether electricity flows, but by speed, availability, payment simplicity, location, safety and what is available nearby while the vehicle charges.
Tesla’s Five-Year Run at the Top Is Over
Tesla Supercharger earned 701 points out of 1,000 in J.D. Power’s 2026 U.S. Electric Vehicle Experience Public Charging Study, putting the network in fourth place. IONNA finished first with 807 points, followed by the Mercedes-Benz Charging Network at 797 and Rivian Adventure Network at 755. The 2026 result represents a striking change for a network that had effectively defined the modern fast-charging experience for American EV owners for much of the past decade.
The historical comparison makes the shift more significant. Tesla Supercharger ranked first among DC fast chargers for a fifth consecutive year in J.D. Power’s 2025 results, scoring 709. It had also topped the category in 2024, when it scored 731. Falling to fourth therefore ends an unusually long period of dominance. Still, the ranking needs context: Tesla’s 701 score remains comfortably above the 2026 DC fast-charging segment average of 666, meaning customers continue to rate the network better than the market as a whole.
Three Newer Automaker-Backed Networks Jumped Ahead
Perhaps the biggest surprise is not Tesla’s position but the identities of the three networks above it. J.D. Power said three automaker-backed charging networks became award-eligible for the first time in 2026, and all three immediately occupied the top positions. IONNA led with 807 points, Mercedes-Benz followed at 797 and Rivian scored 755. Their early performance suggests manufacturers have learned quickly from the weaknesses that frustrated EV owners during the industry’s first major charging buildout.
IONNA is particularly notable because it is backed by eight major automakers: BMW, General Motors, Honda, Hyundai, Kia, Mercedes-Benz, Stellantis and Toyota. Its strategy has emphasized high-powered equipment and more comfortable charging stops rather than rows of chargers placed wherever suitable electrical connections can be found. Mercedes-Benz is following a similar formula. Its North American network offers charging of up to 400 kW and, as of mid-2026, had more than 775 stalls across 25 U.S. states and British Columbia. Competition is increasingly being built around the entire stop, not simply the charger.
Tesla Did Not Collapse — Its Rivals Improved Faster
A fourth-place finish creates the impression of a dramatic deterioration, but the underlying numbers tell a more nuanced story. Tesla scored 709 in the 2025 J.D. Power study and 701 in 2026, an eight-point decline. The overall DC fast-charging segment, meanwhile, climbed from 654 points in 2025 to 666 in 2026. Tesla therefore lost relatively little ground in absolute satisfaction while competitors and the industry around it became substantially better.
That distinction matters because rankings are relative. In 2025, Tesla sat 55 points above the segment average. In 2026, the gap narrowed to 35 points even though its own score changed only modestly. The newest networks also entered with exceptionally strong results, including IONNA’s 807-point performance. For an EV driver arriving at a Supercharger, the experience may still feel familiar and dependable. What changed is the comparison available across the road: newer stations are increasingly delivering faster hardware, simpler payments, more chargers and better-designed locations that narrow or erase advantages Tesla once enjoyed almost by itself.
Fast Charging Is Getting Better Across the Industry
Tesla’s decline in rank occurred during an unusually positive year for DC fast charging overall. J.D. Power measured average satisfaction at 666 points, up 12 points year over year, with improvements recorded across all 10 factors used in the study. Charger availability posted the largest gain, rising 27 points. Satisfaction with both charging-location safety and charging cost improved by 18 points, showing that progress is extending beyond headline charging speeds.
Reliability also moved in the right direction. Only 12% of EV owners in the most recent quarter covered by the research reported arriving at a public charger and being unable to charge, the lowest rate recorded since the study began. That figure was 14% during the comparable period a year earlier and 19% in the 2024 study. Failed sessions remain frustrating, especially when a driver arrives with limited remaining range, but the direction is encouraging. The industry appears to be moving from simply installing more equipment toward making existing charging stops more dependable and easier to use.
Where a Charger Sits Can Matter Almost as Much as Its Speed
Public charging is increasingly being treated like a hospitality business. J.D. Power found meaningful differences in customer satisfaction depending on where DC fast chargers were installed. Chargers located at hotels received a satisfaction score of 692, while gas stations and convenience stores scored 689 and restaurant locations reached 688. Stand-alone parking lots and garages scored considerably lower at 606, while dealership charging locations were at the bottom with 570.
Those results help explain why newer charging networks are paying so much attention to amenities. A 20- or 30-minute charging stop feels very different when there is a clean restroom, food, shelter and a well-lit place to sit nearby. IONNA has promoted its “Rechargery” concept around precisely that idea, combining high-powered charging with canopies and customer amenities at many sites. Mercedes-Benz has likewise partnered with travel and retail destinations. Fast hardware remains important, but the emerging competitive advantage is turning unavoidable charging time into a predictable, comfortable break rather than an inconvenience.
Opening Superchargers to Other EVs Has Made the Experience More Complicated
One of Tesla’s biggest strategic changes has been opening parts of the Supercharger system to vehicles built by other manufacturers. Tesla now says many North American Superchargers can be used by non-Tesla EVs equipped with NACS ports or approved NACS adapters. That dramatically increases the usefulness of the network and helped make Tesla’s connector architecture a central part of North America’s evolving charging ecosystem.
It has also introduced challenges Tesla did not face when every vehicle arriving at a Supercharger was designed around the same charging hardware and software. J.D. Power identified the difference as early as 2024: Tesla owners rated their Supercharger experience at 743, compared with 706 among non-Tesla drivers. Ease of charging and payment were among the largest gaps. In 2025, J.D. Power again noted weaker satisfaction among non-Tesla users relative to charging costs. Adapters, different charge-port locations and pricing arrangements can add friction to an experience Tesla owners traditionally handled by simply plugging in.
Tesla Still Has an Enormous Advantage in Scale
Fourth place in a satisfaction ranking should not be mistaken for fourth place in infrastructure scale. Tesla says its worldwide Supercharger network surpassed 80,000 stalls, and the company reported that the network delivered 6.7 terawatt-hours of electricity during 2025. Few charging businesses operate at anything close to that volume. Tesla has spent more than a decade building sites, integrating charging into vehicle navigation and developing hardware specifically around its cars and software ecosystem.
That scale is simultaneously an advantage and a challenge. A newer network can concentrate investment on a relatively small number of modern flagship locations, while Tesla must operate and upgrade a sprawling mix of generations, locations and customer types. More users also mean more opportunities for congestion and compatibility problems. Tesla nevertheless continues to expand access, and its Canadian NACS information identifies numerous automakers whose vehicles can use or are being integrated with the Supercharger network. The competitive question is therefore changing from whether rivals can match Tesla’s footprint to whether Tesla can keep its enormous footprint feeling as polished as smaller newcomers.
Canadians Should Treat the Ranking as a Signal, Not a Canadian Scorecard
The most important limitation for Canadian readers is geographical. J.D. Power’s 2026 results measure the U.S. charging experience. The study included 6,594 battery-electric and plug-in hybrid owners and was fielded from January through June 2026. Its fourth-place result for Tesla should therefore not be presented as a direct ranking of Canadian Supercharger locations. Charging-site density, electricity pricing, competing networks and regional driving patterns differ considerably between the two countries.
Even so, the competitive shift is becoming relevant north of the border. Natural Resources Canada’s Spring 2026 Energy Fact Book counted roughly 39,000 public EV chargers nationwide, with about 21.6% classified as DC fast chargers. New competitors are also entering. Mercedes-Benz launched its Canadian high-power network in British Columbia in January 2026, beginning with locations in Abbotsford, Pitt Meadows and Tsawwassen and planning eight Metro Vancouver hubs equipped with 400-kW chargers and both CCS1 and NACS connections. Canadian drivers are gradually gaining the same thing that changed the U.S. rankings: credible alternatives.
