What stands out
Electrical accounts for 23% of all owner complaints filed against this vehicle, across 9 categories tracked.
No new NHTSA electrical complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
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 Preliminary Information communication provides information to the technician about vehicles that have an intermittent no crank, no start, or start stall concern with the security light coming on. Technician may find Diagnostic Trouble Codes B3055, B3060, and/or B3935. Technician should not replace any parts for this concern. If unable to duplicate the concern ask if the customer uses any Radio Frequency Identification Devices when the concern is present. Dealer should also direct their customers to the appropriate section in the Owner manuals that references that the device complies.
full bulletin at NHTSA ↗Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

The failure pattern owners describe
The 2009 Equinox electrical troubles cluster around two major problem areas: the driver-side door harness and broad powertrain electrical faults.
The door-harness issue is consistent and alarming. Multiple owners describe wires becoming brittle, cracking, and breaking where the harness enters the driver-side door. Once compromised, the exposed copper strands create risk of short circuits and burning-electrical smell—some owners report the odor both inside the cabin and under the hood. Cascading failures follow: power windows stop working (sometimes only functioning when the door is open), door locks fail, rear wipers quit, speakers die, and even the radio stays on after the engine shuts down. One owner discovered the harness visibly frayed inside the door and expressed fire-hazard concerns. Dealer repairs involve re-soldering broken wires, but multiple owners were warned the remaining wires would fail next, suggesting incomplete fixes.
Separately, several owners encountered severe drivability and safety issues: engine shutdowns while driving with complete loss of gauge function, key stuck in ignition requiring WD-40 or multiple repair attempts ($700+ spent on one car), airbag warning lights tied to loose passenger-seat module connections, and throttle-body failure at very low mileage. One owner's engine-shutdown incident resulted in loss of brake power assist and a T-bone collision injuring two children.
Repeated failures of headlights and brake bulbs, mysteriously linked to window-switch operation in one case (headlight pops when window button pressed), suggest deeper electrical distribution faults. DIC display dimness and heater malfunctions round out the complaints.

Failure modes owners describe
Driver-side door wiring harness failure
Wires in the door harness crack, break, and become brittle where the harness enters the driver-side door. Insulation deteriorates, exposing copper strands. Multiple owners report the harness is inadequately protected and prone to stress cracking at the entry point.
When: 93,351 miles reported in one case; occurs at various mileages
Symptoms owners cite: Driver-side power window inoperative; Driver-side door lock inoperative; Rear wiper failure; Driver-side speaker failure; Intermittent window operation (window works only when door is open); Radio remains on after keys removed
Repairs/costs cited: Wires re-soldered or spliced by dealers; owners report dealership said other wires in harness will eventually fail. One owner replaced window motor to no avail before identifying harness issue. Harness replacement recommended but not always performed.
Electrical fire hazard from exposed wiring
Broken and brittle wires in the door harness expose copper strands and create potential for short circuits. Owners report burning-electrical smell inside vehicle and under hood. Hazard intensified by tight-fitting rubber boot that makes repair difficult and may mask continued deterioration.
Symptoms owners cite: Strong burning-electrical smell inside vehicle and under hood; Multiple electrical functions failing simultaneously in same circuit area; Exposed copper wire strands visible
Repairs/costs cited: No repairs noted for fire hazard directly. One owner states hazard would be difficult to splice in tight spot.
Remote door-lock failure
Keyless remote fails to unlock doors; owner must use manual key. Issue persists even after replacing remote battery. Dealership quoted $300 per door for diagnosis without initial testing, suggesting known issue.
When: By 2015, over 1 year unresolved
Symptoms owners cite: Remote unlock inoperative; Manual key required to unlock driver side, then manual unlock of other doors
Ignition switch key-removal difficulty
Key becomes stuck in ignition; requires several minutes of working or WD-40 application to remove. Recurs after dealer repair attempts at significant cost.
When: 150,000 miles in one case
Symptoms owners cite: Key stuck in ignition; Key requires excessive force or lubrication to remove
Repairs/costs cited: Dealer applied WD-40 as remedy; owner reported $720.72 in repairs at dealership with problem unresolved; additional $200-$300 attempted fix offered but uncertain to work
Engine shutdown and limp-mode while driving
Engine shuts off without warning while driving; all gauges drop. Vehicle enters limp mode, reducing power dramatically. Owner reports loss of brake power assist on one occasion, resulting in inability to stop at traffic light and serious accident (T-bone collision).
Symptoms owners cite: Engine shutdown while driving; All gauges go to zero; Severe power loss (reduction from 40 mph to 3 mph); Engine remains running after ignition turned off and key removed; requires multiple on-off cycles; Loss of brake power (in accident scenario)
Throttle-body failure
Throttle body fails at low mileage, causing dramatic acceleration loss and severe deceleration while driving.
When: 300 miles reported
Symptoms owners cite: Acceleration power reduced dramatically; Vehicle decelerated from 25 mph to 3 mph
Repairs/costs cited: Throttle body replaced at dealership
Traction control and stability control light illumination with power loss
Stability traction control light illuminates along with other warning lights; vehicle loses power and slows dramatically. Dealership repair performed, but light reappears periodically at startup thereafter.
When: Periodic recurrence every 3 months
Symptoms owners cite: Traction control light on; Multiple warning lights; Power loss (vehicle slowed from 40 mph to 20 mph); Light recurs periodically at startup without other issues
Repairs/costs cited: Repaired at dealership; issue recurred
Service traction control and engine power reduction messages
Dashboard displays 'Service Traction Control,' 'Service Stabiltrack,' and 'Engine Power is Reduced' messages; dealership and independent mechanic unable to diagnose root cause.
Symptoms owners cite: Service traction control message; Service stabiltrack message; Engine power reduced message
Repairs/costs cited: Independent garage unable to diagnose; owner referred to dealership
Passenger-presence detection module failure
Airbag presence detection module fails or malfunctions, causing airbag warning light to illuminate intermittently. Light illuminates when passenger sits still but turns off when passenger moves. Passenger seat presence sensor connections are loose and unsecured, dangling below seat.
When: 85,500 miles reported in one case
Symptoms owners cite: Airbag warning light illuminates and extinguishes intermittently; Airbag light on when passenger sits still, off when passenger moves; Loose module connections below passenger seat
Repairs/costs cited: Passenger presence module replacement quoted at $800+; dealers advise checking loose connections below seat
Headlight failure (repeated)
Headlights fail repeatedly at short intervals; also linked to window switch operation—headlight blows when window switch pressed or door opened.
When: Replacement every 3 months; 3 replacements in 5 weeks reported in another case
Symptoms owners cite: Both headlights failed; Headlight pops and fails when window switch pressed; Headlight fails when door opened; Passenger-side window intermittently inoperative
Repairs/costs cited: Bulbs replaced multiple times
Tire-pressure monitoring light and throttle anomaly
TPMS light illuminates continuously; concurrent with throttle-body failure causing severe power loss.
When: Low mileage (300 miles reported)
Symptoms owners cite: Tire pressure monitoring light continuous
Repairs/costs cited: No repair noted; throttle body replaced
Brake light failure (repeated)
Brake light bulbs fail and require replacement multiple times within short periods.
When: Four failures within one year reported

In 2015, I took my car to monument Chevrolet and told the dealership that my car is not unlocking the doors when I am using the remote. I had to use my key to unlock my driver side door manually and the reach over to unlock the other doors. Before the dealership even ran a diagnosis test, they told me that it was my lock mechanism and it was going to cost me $300.00 per door to find the problem.…
