What I experienced was VERY quick, like literally milliseconds from what I remember, almost enough to 'ignore' it because it seemed to happen so quick that you thought, did that happen? It felt like everything just 'shut down' but then all came immediately back up with nothing to let you know it really happened... I was on the highway going about 65mph the one time it happened and the other time I was going about 35mph. Both times it just felt like a complete power down but then IMMEDIATELY everything just resumed to normal and all worked fine. Like I said, I LOVE my Crossfire and I hesitate to mention something to hubby until I KNOW it's an issue for fear he'll say "that's it" I can't trust your car to get you there safely so I didn't bring these instances up until... the dreaded, go out to start my car after work and NOTHING... everyone thought it was the battery (all the helpful folks at my office who wanted to diagnose my problem) and I KNEW it couldn't be the battery as I'd just replaced about a year and a half before and this time experienced none of the tail fin craziness that accompanies a failing battery on the Crossfire. Sure enough, a quick search in the forums told me it was RCM and Hubby removed, soldered, replaced and no issues since.

That's my story and I'm sticking to it!
