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.
No new NHTSA electrical complaint has been filed on this vehicle in over 9 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2016 Traverse has a pattern of electrical and control-system failures. Stabilitrak faults causing engine derate, blind-spot module water intrusion ($1,350–$1,900 repair), unexpected airbag warnings, and intermittent stalling appear across multiple narratives. Service departments often cannot diagnose root causes, and GM has not issued recalls for known issues.
Owners of 2016 Traverses describe a cascade of electrical failures that dealers struggle to pinpoint. The Stabilitrak and traction control system triggers power loss on highways without a clear diagnostic code—dealers sometimes replace relays or entire fuse boxes, with one part on national backorder. Multiple owners report the vehicle loses power abruptly, forcing a pull-over, then restarts normally until the next cycle.
Blind-spot detection modules fail from water intrusion and corrosion, particularly at the rear bumper wiring connection. When this happens, the electrical system misbehaves dramatically: turn signals stop working, gauges go dark, speedometer fails, and airbag and tire-pressure lights activate while driving. Repair cost runs $1,350–$1,900 and is not covered under warranty. Owners note dealers confirm this is a known issue but GM has not recalled it.
Other electrical issues include an airbag warning light that recurs after restart, a driver information center display too dim to read during daytime, and one case where the vehicle's entire electrical system shut down in a parking lot, requiring three hours of roadside troubleshooting. Battery drains, window-washer pump shorts, and radio failures also appear. Dealers often cannot diagnose the root cause, citing no available service information from GM.
