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!!!!
Ive noticed that my car while sitting rather at a redlight or in park in the driveway has a miss yet no check engine light the ac was not running took to dealership at 26,000 and they even said it had a miss but since its not logging a code (light) its not worth fooling with yest it does however concern me and its still doing it
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
My car will shake mostly at redlights or stop signs but the engine light did not come on. The engine light came on briefly and went off and I had it towed to the dealer. They told me that there was antifreeze in my oil and oil in my antifreeze, there was a blown head gasket and he named some other things that was wrong. they told me it will be approxiamtely $5,500 without tax and labor. I had my car towed to a garage. Just waiting for them to give me a price. Hopefully, it will not be as high as the dealer.
my rpms are going up and down. and my engine light is on like wtf lol I hate Pontiac's and GM they suck @SS my other car run better then my other car is a 1993 Nissan 240sx its has 187,000 lol and run better then my Pontiac g6 lol
My car just dies randomly. I've tried air off and air on ive got stranded numerous times. And wait about 5-10 minutes and it will start back up running rough. I've had 3 people look at it.found some wires that got hot and grounded out. Got those fixed. The car ran for a day and a half without dying now it's doing it all the time. Idk what to do!?!? No check engine light.
06 G6 GT. 150k miles. CEL pulled random misfire code. Rather than troubleshoot all that it could be, decided to pay the diagnostic fee to pinpoint what it was, at GM. Was told that two spark plugs were bad. Replaced all the plugs. Within 5 minutes of driving, CEL again, random misfire. Dropped it back off with GM. A week later, diagnosed with low compression in one cylinder, possibly resulting in a misfire. Not amused. Car has been one problem after another. 4 recalls in all. Replaced multiple less than adequate OEM parts on the car. Steering rack still clunks. Now, needs a motor? Will not buy another GM.
The car was missing, jerking, or acting like I kept stepping on my breaks. I parked it and had it towed to dealership. Paid for $99.12 for a diagnosis. The computer came back with nothing. They test drove it and nothing happen. The car had been sitting at the shop for 3 days before they got to it. I parked it on Friday and towed it on Monday. So it had time to rest. I will get it back today. If something happens again I will update this.
