GMC Yukon electrical problems, 2016–2027
376 of the 2,908 complaints owners filed with NHTSA about the GMC Yukon 2016–2027 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 (90), 2023 (64), 2017 (53). Filed under the same heading across these years: 1 recall campaign. 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: 1 · 2017: 3 · 2018: 19 · 2019: 25 · 2020: 24 · 2021: 20 · 2022: 32 · 2023: 28 · 2024: 32 · 2025: 104 · 2026: 88
Across the model years, half of the 90 owners who gave an odometer reading reported the electrical problem between 21,000 and 64,000 miles. A median of reports, not the life of a part.

Rear tail lights (brake lights) work intermittently. There is a "special coverage adjustment" but it is set for a maximum number of miles or time (6-years). I have a 2016 Gmc Yukon Xl. The passenger's side was replaced in 2018 and now the driver's side is defective/inoperable. But because we are at 96000 they won't repair
I have been notified on two occasions on the road that my tail light was out. When I was able to check them, both tail lights lit up then turned on. It must be an intermittent issue
Rear camera for in cabin rear view is improperly sealed for cold weather and constantly fogs which renders the camera worthless. I was also sent brand new side lights from gm that were improperly sealed and built condensation them after a month or two

THE BRAKE LIGHT IS OUT AND A SINGLE TAIL LIGHT IS OVER 500$ Very dangerous to have tail light out and can cause an accident. There should be a recall on these defective LED lights
