Vapor began coming in through the air vents, along with a super-sweet smell; this smell was later identified as leaking engine coolant. The front windshield quickly fogged up beginning on the passenger side and absolutely would not clear. Using the vehicle's defrost only increased the windshield fogging and severely decreased visibility. Fogging and visibility is worse when the weather is cool or it is raining, and the coolant smell inside the car can make you sick and give you headaches. Fog-free window treatment is ineffective.

Taken to the Chevrolet dealership service center, the Camaro has a bad Heater Core - to fix this extremely hazardous issue, the Camaro's windshield must be taken out along with the dash and seats just to gain access to the heater core... at a cost around $2,000 and over a week in the service center...

Beware, this is not covered under Chevy's Powertrain Warranty (the heater core is excluded). This is a very common problem with newer model Camaros and should be a GM recall by now. I was able to pull off the interstate before my visibility was reduced to zero... Somebody else may not be so lucky, or may not know what's going on when their windshield begins to fog.
