What stands out
Owners have filed 50 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 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 communicates to the dealer the process for downloading or updating operating software for the Tire Pressure Monitor, Active Fuel Injector tester, multi media tester, PICO Scope, GR8 starting/charging tester and Vehicle Data Recorder tools, giving website address and step by step instructions to complete the update.

full bulletin at NHTSA ↗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 2010 Traverse electrical system shows a clear pattern of serious, recurring failures. Engine stalls without warning on highways and city streets—some owners lose power at 70 mph with children in the car. The vehicle enters limp mode, reducing speed to 10–25 mph and refusing to accelerate; owners report this happening three times within six months on the same vehicle. Throttle body and throttle position sensor replacements ($500–$600) sometimes work for just three months before the failure returns.
The engine continues running after the key is removed, forcing owners to cycle the ignition multiple times before shutdown. Battery drains from this alone, making the car hard to restart. One owner paid $200 for an ignition switch replacement—it lasted one week, then the same problem recurred because water had entered the fuse box in the glove compartment, requiring a $1,200 rewire that still failed.
Radio and infotainment systems won't shut off when the vehicle is off, backup camera beeping continues indefinitely, and windows roll down on their own. Air conditioning stops mid-drive (one owner fixed it three times). Check engine lights stay on indefinitely with dealers unable to find causes. One vehicle caught fire while parked; the fire department found hot wiring inside. Owners describe the electrical system as unreliable and dangerous, with multiple failures happening simultaneously or in quick succession.
