The failure pattern owners describe
Water intrusion ranks as the dominant complaint across this cluster. Multiple owners describe water pouring from the sunroof and dome light area into the cabin—notably, complaint #1 emphasizes this happens only while driving on the highway, not when parked, distracting the driver enough to raise safety concerns. One dealer confirmed the problem is a design flaw that cannot be repaired. Water also enters through rear doors during rain and leaks into the trunk near the bumper and spare tire well, pooling on the passenger-side floorboard and breeding mold under the carpets. One owner notes the mold created health concerns.
Door lock failures are prevalent: rear passenger-side locks work intermittently, forcing occupants to crawl into the back seat or manually unlock from outside. One owner couldn't open either front door. A sunroof glass panel spontaneously shattered at 70 mph on the interstate, landing in the driver's lap. On the G6 convertible, plastic hinges cracked during normal top operation.
No owner reports successful permanent repair. Dealers either cannot fix the water issues or claim they can only to see the leaks return months later. One owner received an extended warranty that's already expiring, leaving them exposed to out-of-pocket costs.
