Oh yes, very familiar with this problem on my 2008 Malibu!! It has been in the shop three times now and the dealership could not figure out the problem. They are now fixing the throttle body on it. I hope this works as the car starts to power the engine down when it says service traction, ESC off and I can not go over 40 mph! I only have 22,ooo miles on it- so I am praying they fix this before it's out of warranty. It really is a beautiful car, all problems aside.Once in a while, I get the message to service traction and ESC. Now the wrinkle to all of this is that, if I turn the car off and restart, it goes away. Anyone have this issue? It has happened a few times now and is never there when I restart the next time.
