Hyundai Tucson electrical problems, 2016–2026
685 of the 5,085 complaints owners filed with NHTSA about the Hyundai Tucson 2016–2026 name the electrical system (NHTSA’s “Electrical System” heading — wiring, modules, batteries, charging, infotainment and driver displays — NHTSA's broadest heading). The loudest years: 2016 (216), 2025 (118), 2017 (84). Filed under the same heading across these years: 11 manufacturer bulletins, 4 recall campaigns, 1 NHTSA investigation. Every figure is a linked federal record; none is a failure rate, none a repair cost, and none a verdict on one car.

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: 2016: 17 · 2017: 14 · 2018: 16 · 2019: 33 · 2020: 41 · 2021: 84 · 2022: 61 · 2023: 89 · 2024: 69 · 2025: 127 · 2026: 134
Across the model years, half of the 189 owners who gave an odometer reading reported the electrical problem between 8,000 and 68,000 miles. A median of reports, not the life of a part.
In owners’ own words

The contact owns a 2016 Hyundai Tucson. While depressing the accelerator pedal, the vehicle failed to operate. The failure recurred numerous times. The vehicle was taken to a dealer and repaired, but the failure persisted. The VIN was not included in NHTSA campaign number: 16v628000 (electrical system, power train).
The contact owns a 2016 Hyundai Tucson. The contact stated the vehicle experienced unintended deceleration and stalled while driving 60 MPH. The failure occurred without warning. The vehicle was taken to the dealer where it was diagnosed that the vehicle operated as designed. The manufacturer was notified of the failure.
The Integrated Charging Control Unit (ICCU) failed on my 2025 Hyundai Tucson PHEV at approximately 6,600 miles. The failure manifested through multiple concurrent symptoms. First, the vehicle displayed a "car not charging" warning light and completely refused to accept an electrical charge when plugged into a charger.
My entire dashboard goes black and I lose all directions and functions in car. It happens when driving often. Additionally after taking to dealership, it's getting worse. Now warning lights come on and stay on such as master warning lights, batteries, power steering, etc.
N june 24, 2019 I discovered my vehicle was cyber control hacked.. Mysterious radio code, interference with sirius radio signal, channels kept changing, cannot control volume, discovered an alien iphone connected to blue tooth, malicious link appeared on 6/11/19 when radio was taken down to manufacturing settings.
