Greetings all!
New Crossfire owner here. I stumbled across this forum while googling crossfire quirks.
I have a 2005 roadster. It only has 31,000 miles on it. I actually traded my 2004 Chevy SSR for it.
It's in excellent shape so far, The convertible roof was quirky at first, but after researching "top issues" I found the hydraulic reservoir was only about 1/3 full.
After I filled it and manually raised and lowered the top a few times, refilled again, and it's been perfect ever since.
All in all it runs extremely well, ( so far)

I have a quirky ambient temperature sensor loves to read -36 degrees. I replaced the sensor and it appeared to work.( for about 24 hours)
Now it will read approximate real Temperature, and then at some point drop to -36. So now it sometimes works, sometimes not. I have no idea why. Sometimes it just wakes up and other times falls back to it's -36. Very annoying to say the least.
