When does it fail?
Of the 29 electrical complaints filed for the 2020 Chevrolet Equinox, here's the actual mileage breakdown — failures cluster heaviest at 0-25,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
Owners have filed 29 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This service bulletin provides information on the proper Reflective High Temperature Heat and/or Insulating Tape to use for certain repairs, such as Wiring Harness Repairs.

The failure pattern owners describe
The 26 complaints describe a complex electrical landscape affecting both safety and infotainment systems. The infotainment unit is the most frequent failure point: owners report it shutting off during drives, sometimes cascading into failures of OnStar, turn signals, backup cameras, and mirror warning functions. Dealers have replaced entire radio consoles and applied software updates, but failures persist. General Motors has offered minimal reimbursement, citing mileage.
Critical safety issues include brake system failures—stiff, unresponsive pedals without warning and intermittent brake assist warnings that dealerships cannot reliably diagnose despite vacuum pump and booster replacements. Engine stalling at highway speeds and in traffic occurs without warning lights, sometimes preceded by auto-stop electrical dropouts. Check engine lights with misfire and sensor codes persist across multiple service attempts, including at 5+ months in one case.
Other recurring electrical gremlins include premature battery failure (shorted cell within 50 miles of factory replacement), door locks freezing in cold, lane departure false warnings, and a transmission control error preventing start or shutdown. One owner reported unresponsive dealer service—claiming a simple software fix, then keeping the vehicle eight days. Water intrusion and sunroof failures, fuel smell through vents, and erratic electrical component behavior during braking rounds out the reports. Owners consistently note the intermittent nature makes diagnosis difficult and repairs expensive.
