When I was in the market for a GTO in 2004, I was walking around the dealership and walked into the garage area where they were detailing the cars. I came across a Silver 2004 GTO and one of the guys saw me sweating the car so he yelled, 'hey buddy'...and the key was flying in the air. He told me to 'fire it up', of course I did. I started the car and after the system check, the 'overheat' message came up and I believe the needle was pointing into the red zone as well. Needless to say, I got freaked and shut the car off immediately and told the guy about it. I'm not sure what they did to fix it, but he did mention they'd have a look at it and check the computer. Perhaps it's a glitch in the 04's system, but even if I knew the temperature wasn't as high as the gauges suggested, I wouldn't be comfortable driving it.
