U.S. Public EV Charging Network Sees Reliability Gains Led by Tesla

Shifting NEVI funding guidelines raise fresh hurdles after network reliability hit its best level in years, with rising charging costs especially hitting non-Tesla drivers.

Overview

  • J.D. Power’s 2025 study reports non-charging visits fell to 14%, the lowest rate since early 2021.
  • Tesla Superchargers recorded the fewest failed visits at 4% and led satisfaction with a 709 score despite a 22-point drop year-over-year.
  • Non-Tesla drivers using Superchargers cite less streamlined payment processes and often face higher per-kWh rates than Tesla owners.
  • Overall cost satisfaction declined sharply, with Level 2 chargers scoring 459 (down 16 points) and DC fast chargers at 430 (down 16) on J.D. Power’s 1,000-point scale.
  • President Trump’s February pause and subsequent resumption of NEVI funding under revised guidelines injects short-term uncertainty into charger deployment and upkeep.
