Owners have filed 58 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.
No new NHTSA electrical complaint has been filed on this vehicle in over 10 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 2008 Equinox shows a pattern of cascading electrical failures that start early and compound over time. Door locks are the most common complaint—owners report them failing to engage via key fob or interior buttons, forcing manual unlocking of all doors. Some locks partially engage or work only in cold weather. Driver-side windows are frequent victims, becoming inoperable or working intermittently until they quit entirely. The ignition key gets stuck and won't eject from the switch; owners describe waiting a minute or more, hearing clicks, and having to manipulate the steering wheel to release it. Warning lights—SERVICE STABILITRAK, SERVICE BATTERY CHARGING SYSTEM, SERVICE TIRE PRESSURE MONITORING SYSTEM, and SERVICE AIRBAG—come on repeatedly, sometimes for no apparent cause. The passenger airbag sensor is particularly problematic, activating and deactivating at random or remaining off even with a properly-weighted occupant present. Instrument cluster failures include speedometers pegging at 120 mph with audible clicking, then slowly dropping back to normal over days. Headlights hold moisture; brake and tail lights blow frequently. Static electricity shocks are severe and persistent. Multiple owners report wiring harness degradation at the door jamb transition with exposed copper, cracked insulation, and brittle wire. Dealers have been unable or unwilling to permanently fix these issues, citing intermittent conditions, parts availability, or high repair costs ($500–$1,200 per repair). Some owners say repeated dealer visits yielded no resolution.

What owners are reporting 3 most recent
Passenger side airbag sensor doesn't go on or goes on and then turns off while in car driving or stationary. Moving around on seat makes it switch back and forth. Looks like this is the same issue from the 2007 recall, but not extended to 2008. Haven't taken to dealership yet, but seems to be a common problem. Was sold to me last month from a used car dealer.
Driver door will not lock or unlock when inside the car. This is a safety issue as I would not be able to get to the other side of the car in order to get out. Window must be rolled down in order to reach outside and open the door . Vehicle was parked and I was trying to open the door with the handle and something came loose and door would not open from inside or with the automatic door lock.
My 2008 equinox has been having problems with starting, it's fine when it's sat over night hours but during the day when it's only sat a couple or a few hours it will hesitate and I've taken it to the dealership where I purchased it and they kept saying nothing is wrong but it continues to do it, so something has to be wrong and the passenger front window doesn't go down and I had been taking it…
