    Started missing when you come to stop at a signal light. Very annoying. Took the auto repair shop.Hooked up too computer but not showing anything wrong. Did tuneup, didn't work. Next changed the throttle body. That didn't work. Checked gas tank, had some sludge and a little water. So took it off an cleaned and also cleaned the fuel lines. That still didn't work. Finally someone came from a dealership to the shop. Said he thinks he knows what it is. Had some kind of computer system from the dealership. Hooked it up. Showing it had a bad coil wire. Computer knows which one. So only had that one replaced for now. Guess what, it's working right now. So for now I very pleased.

    All of these people with this same problem, clearly it is something general motors is doing wrong along with the other things(recalls) but you think they will fix it? No, why? because they are rich people who DONT CARE about anything except making millions. They make their products to fail, so that you have to spend money to fix it and they continue to make money!!! So here i am stuck with a 14,000 dollar car that i had for 1 week before it started acting up, and needs a new motor because it cost more to fix the piston! 14,000 dollars for a care that needs a new motor!!! My advice, NEVER buy from them!!! Wish i never got this stupid car!!!!

    my g6 also had a misfire problem on cylinder 1 and 3 with the 3.6v6 VVT engine, hey changed spark plugs and the ignition caps. i actually found the problem online. its not a 'G6" problem its a cadillac problem its there engine and its due to poor timing chains. if you let your oil change go past the 5000km mark even though ur display says 65% oil life remaining the chains expand with heat and throw the engine timing off. once it gets it half inch out ur engine light will come on. there are 3 chains in that engine. get it done before the crank gets ripped up

    At a stop my car would sputter or shake. I was told it was misfiring in one of my cyliner's and that it is either the coils or wires. Not fixed yet.
