There is no specific information indicating that Tesla Superchargers are less reliable in particular regions compared to others. However, the overall reliability of Tesla’s Supercharger network is noted to be significantly higher than that of other charging networks. A recent Consumer Reports study found that issues were reported in just 4% of charging sessions at Tesla Superchargers, making them the most reliable.
While there isn’t specific data on regional reliability issues for Tesla Superchargers themselves, other charging networks, particularly non-Tesla DC fast chargers, have shown regional variations in reliability. For example, states like Utah, Alaska, Tennessee, North Carolina, and Nevada were ranked as the top regions for DC fast charging reliability in Q1 2025.
It’s worth noting that the general reliability of Tesla Superchargers is likely consistent across different regions due to their integrated system and control over both vehicle and charging station hardware and software.
