Two things the counts carry that are not the car: how many of each year were sold, and how long each has been on the road — an older year out-counts a newer one before anything is wrong with it. The share column is the honest comparison across years: what part of that year’s complaints named the electrical system. Nothing here is a rate.
When the electrical complaints were filed, and at what mileage
Source: NHTSA complaint databaseFiled per calendar year, every model year together: 2022: 6 · 2023: 159 · 2024: 97 · 2025: 248 · 2026: 499
Across the model years, half of the 38 owners who gave an odometer reading reported the electrical problem between 8,000 and 28,000 miles. A median of reports, not the life of a part.

When AC charging my car, It quickly overheats and disables charging. I've measured the temperatures at 239°F using OBD reader. The only way to continue charging is to reduce charge amperage. If it is reduced to 32 amps the temperature seems to stabilize before reaching the 240° emergency cut off
Twice this week while charging my Ionic 5 the charging stops before it is completely charged to the set point. Once the set point was at 80% and once at 100%. Both times the charging stopped and I received the message below. None of the reasons listed in message was a cause of the stopping.
Integrated Charging Control Unit (ICCU) failed while driving. Heard a pop from below the rear seats. "Check vehicle electrical system" message popped up initially, then changed to "Stop vehicle and check power supply" Vehicle could not exceed 20mph directly after failure, then lost all driving power just as I pulled the vehicle off the…
