Let's be honest here, has anyone here had an issue with their shutting down or the keys falling out?
I haven't so I am not going to get myself all worked up and/or park the car in fear something is going to happen.
I've done a bit of research on this. Of the 5 or so Facebook groups I am on, I found only 1 Solstice owner who posted a picture of a banged up Solstice and said his car shut off and he got into an accident because of it. Damaged looked to be cosmetic.
There was a post on the Sky forum from a member who said his car had shut off on him twice when going to work. He had a long communte, something like 40 miles, and he was going to take a loaner since his car had the issue.
Next I asked Mom's about this since she is an admin on the big boards also. She said she personally knew of one Kappa who had the issue. She did a quick search of the forums and didn't find much in the way of complaints about engines shutting off. I couldn't remember many either.
That makes only 3 that I am aware off.
So for whatever reason, I suspect this not the norm for our cars and is more prevalent in the Cobalts and Ions either because there are more of them, or there is something just a touch different about the installation in our cars (location, location of steering column, angle of install, etc).
That being said, what I have seen a lot of and have personally witnessed is the key becoming stuck and won't move. Either while the car is running or when the car is off. The key won't do anything. Won't come out, won't turn either direction, you can't wiggle the car, you can't wiggle the steering wheel...it refuses to move. I've seen complaints on the forums of this, on Facebook, and I've personally witnessed it in a friend's 2007 Sky. This has happened to 2007, 2008, and 2009 model year cars. I can't think of an 06 Solstice that has done this off hand. But for certain I know it has happened in 2007-2009 MY kappas.
Sooooo...Like Bob, I'm going to take the same approach. I'll either end up with a car that randomly turns off, or one that won't turn on or off!!
