Chevrolet Silverado 2500HD electrical problems, 2016–2026
207 of the 818 complaints owners filed with NHTSA about the Chevrolet Silverado 2500HD 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: 2024 (55), 2022 (29), 2019 (19). Filed under the same heading across these years: no document yet. 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: 1 · 2018: 3 · 2019: 6 · 2020: 7 · 2021: 8 · 2022: 12 · 2023: 35 · 2024: 47 · 2025: 51 · 2026: 36
Across the model years, half of the 43 owners who gave an odometer reading reported the electrical problem between 2,000 and 64,000 miles. A median of reports, not the life of a part.
In owners’ own words

The GM brake controller will disconnect with the trailer being pulled. You get a message on the information center that the brake controller has lost connection with the trailer or no trailer brakes are available, something to that effect. This has happened up to 5 times in one day. You never know when this will happen.
Instrument Cluster screen blinking On/Off and showing "Service Instrument Cluster" message. Lost all indications of speed, warnings, gauges, gear selection. Could not tell if vehicle was performing correctly. All sensors appeared to be working, but indications to driver missing
After driving truck. Attempt to turn KEYED ignition off, they key will not move the the off position for removal. Must wait several minutes for the key lock mechanism to release then remove the key
While towing our camper, the trailer brakes constantly turn off and on. The camper dealer already checked over the camper wiring, and hooked it to Ford and Ram tow vehicles and could not replicate the problem. The problem is obviously with my Silverado.
