Owners of the 2009 Traverse describe a wide range of electrical failures that come back after repair. The most common complaint is headlight bulbs failing repeatedly—sometimes both at once—with owners having them replaced multiple times in weeks or months. Engine misfires are another major issue; owners report the service engine light returning with the same trouble codes days after sensor replacement and computer reset, despite also replacing spark plugs, coils, and fuel injectors. One owner documented replacing catalytic converters three times in a year with no permanent fix.
Other recurring problems include a tire pressure monitoring system warning light that won't stay off despite multiple sensor replacements and relearning procedures, and traction control or StabiliTrak warnings that illuminate suddenly. Several owners report the A/C stopping while driving and refusing to turn back on. Water intrusion into door connectors and A-pillar/B-pillar harnesses is documented in multiple narratives, causing corrosion, speaker failures, and disabled warning chimes. Safety-critical failures include an airbag system that failed to deploy in a collision and liftgate sensors that won't stop the door from closing on occupants—one incident resulted in injury. There are also reports of complete electrical shutdown while driving, electronic door locks trapping passengers, and dashboard dimming. GM Technical Bulletin PIP5038B has been referenced for misfire issues, and some owners mention existing recalls on related models.
