Chevrolet Tahoe electrical problems, 2016–2027
245 of the 1,703 complaints owners filed with NHTSA about the Chevrolet Tahoe 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: 2021 (56), 2023 (38), 2022 (37). 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.

In owners’ own words
Source: NHTSA complaint databaseFiled with NHTSA by the people who own these cars, about the electrical system, from the model years with the most to say. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.
I was driving the vehicle and it suddenly lost power - going from 55 MPH down to 0 then the engine just stopped. No warning lights went off, no stalling, no engine noise- completely lost power. Would not start after that for 20 minutes. Started after 20 minutes- and ran fine -like nothing happened.
My tahoe has shut off several times. I am sometimes at a red light and it shuts off and won't turn on or itll eventually turn off but it has a ton of errors on the screen. This has happened about 6 times. Today, April 6th, it wouldn't even start. It has started at the dealership but the screens are blacked out.
I filled my car up with gas and turned it on and it started shaking. Several warnings popped up on the dashboard screen including, Service ESC, Service traction control, And forward collision system unavailable.
When we first purchased our 2023 Tahoe the engine was making a tiking noise we took it back and they told us it was because it was brand new time past engine always needs oil when we drive it u have to press gas pedal it also has electrical problems back camera turns on and off . Brake sensors don’t work .
Transmission Failure/Windshield Wiper Failure- While traveling approximately 48mph, the vehicle completely locked up. Tires screeched, vehicle came to a grinding halt. Two of my children were in the vehicle (15yrs and 7yrs of age.) This was sudden and without warning!
