The failure pattern owners describe
Buyer takeaway: Electrical gremlins plague this model year: dashboard blackouts, phantom touchscreen inputs, charging/battery hazards, and multiple failed components (HVAC, transmission fuse box, ignition switch). Even on-warranty repairs often don't stick, and dealers struggle to diagnose intermittent problems.
Owners report a sprawling electrical problem set across the 2015 Canyon. The most alarming: dashboards go completely dark while driving, multiple times for some owners, with dealerships unable or unwilling to diagnose when the failure isn't happening. Backup camera displays dim dangerously in sunlight, making it difficult to see objects behind the truck. The touchscreen and infotainment system behave erratically—buttons click themselves, radio stations change without input, and the screen freezes up, all while you're driving.
Transmission control has crapped out twice in some trucks, with the TCM fuse burning out during acceleration in turns, leaving the truck in limp mode. One owner's ignition switch trapped the key so badly it had to be repaired twice, with GM refusing the warranty claim. The HVAC system failed twice in one truck within a year—both times producing only cold air and requiring full dashboard removal costing over a thousand dollars. At 590 miles, one truck suddenly lost power and caught fire under the hood. Brake assist and StabiliTrak systems throw false warning codes that keep resetting even after the fuse is checked. One owner's battery saver light came on, the vehicle shut down at 40 mph, and flames erupted under the hood 45 minutes later.
Dealerships are inconsistent: some tell owners it's a known problem with no fix, others refuse to diagnose intermittent issues, and GM has acknowledged some faults but offers no timeline for repairs.
