Went to the dealership to let them know that my car had a loss of power in acceleration. They sent me home saying nothing was wrong. Came back a few days later as my exhaust was very loud. Was told it was all in my head. Finally after a few more days I took it to the Ford dealership, they looked at it because my car would not shift at a high RPM. They replaced the Mass airflow censor (which needed to be replaced, but was not the whole problem)

After driving around for over a month wondering what it could have been I called a buddy of mine and had him look at it.. Simple fix, needed the dealership to run a compression test to determine it was the catalytic converter.. Go figure those jerks wouldn't do that in the first place! Would have cost me less money in diagnostics, and then the hassle of me returning to yell at them!

I'm ready to pick up my 2006 Pontiac G6 and throw it out of the widow. This is my 3rd Catalytic Converter in 2 years, these things are not cheap. Not to mention my camshaft actuators are shot AGAIN. Every time I drive it's like my gears are stuck when the car is shifting. It's a good thing Pontiac is no more, I would not buy another G6 if someone paid me.

The thing is GM and Chevy are one and the same and all the Chevy's I've had, I've never had these types of problems. This car is costing so much money to fix i don't know what to do. Does anyone know why I'm ripping through Catalytic Converter the way I am? I'm paying for this out of pocket.

The car began decreasing speed while on the freeway and I barely made it off the exit at 15 mph. The check engine light then came on and I had diagnostics done and it was the catalytic converter. Luckily this time, GM covered the replacement. Let it be known, that if you have this problem with your G6 and it has less than 80,000 miles, GM HAS TO REPLACE IT FREE! They don't always want to to tell you this! Make sure that you demand to have it covered by the warranty. The government requires them to do this for you!

Third time having a converter issue. Mid Nov 2010, I took it to the dealership for a check engine light. They said my catalytic converter on the right was faulty. replacing it would cost $860. Although I had brought it in for a transmission flush, they identified that problem and gave my car 3 weeks before it would die. Six weeks from then, today, Jan 12, 2011, my right side converter shows no faults but the left needs replacement, since once again, my "ENG PWR REDUCED" message showed. My vehicle is only getting 270miles/tank and goes through a quart of oil per day. This problem is persistent and although I ensure making the most out of my investment by taking care of it, this and other problems having been sprouting up right after the 100,000 mile mark. Never again will I by another GM vehicle....

my catalytic converter was changed at 23,000 miles and now its out again at 95,000 miles. I called GM and the told me to bring it to the dealer and get an engine analysis to see for sure if the converter is faulty and the may fix it free scence it has been the second time it would have failed. The only problem is I have no idea when I will get it changed because the guy at GM told me they have a nationwide backorder for the converter.

Other Problems with the car: Front driverside Tie rod: ( failed at 18,000 miles and needs another one now at 95,500) Power steering assist: ( started coming on about 3 years ago) I'm getting the recall on this one on tuesday. Service air bag Soon Display: ( came on when I pulled out the dealership and comes on atleast 3 times a month. Dealer said that noting is wrong with it because the can't duplicate the problem. Unknown issue: everytime i shift from park to a gear it makes a loud popping noise and while i'm driving, when it shifts it pops too. Took it to the dealer to get the trans checked and flushed. I was told that the trans is fine and that it is something in the engine that causing this problem I cant remember what he said.

When will gm realize that they F-ed up when they made this model g6 and recall them.
