2009 Chevy Traverse, problem after problem and only had about 2 months

What state are you in? Who told you there's no lemon law there? You may file a complaint on the dealer through the secretary of state or attorney general's office. By chance did you check the history before you purchased the car? It can tell you a lot sometimes....

Mine did the same thing and it was the cat converter take it off and change it that should help

No the cat is not the problem....its the HIGH pressure fuel pump that runs off the side of the cam that is leaking into the oil causing it to have the smell and fuel is bad badddd lubricant breaking down the oil prob causing it to " desil" whenever it's shut off occasionally correct?

You have a serious problem and I know how to fix your delimma unless u have solved this already

GuruXX3MB- we have the exact same thing going on with our 2010 Traverse. It’s been at a shop for a week and a half and so far he’s checked sensors, replaced spark plugs and tried replacing the ECM. He now says he thinks it’s the timing chain and will cost over 2,000 to fix. This is getting beyond frustrating as we’ve already thrown so much into this car. Any ideas? Thank you

Guru, Did you ever locate the problem with your 2010 Traverse? Mine is doing the same thing.

I have 20009 Chevy Traverse everything been done but it won't accelerate unless ur easy with gas pedal then its fine no codes doesn't throw engine light at all

So we are having same issues with my daughters 09 Traverse. Anyone figure out what the issues were??

I am having the same issue as well in a 2009 Traverse 3.6L 2WD/FWD. I have replaced the stater, replaced the timing (just a heads up for anyone trying to do that on your own, a lift is an absolute necessity to do it while it is still in the vehicle. I can give step by step directions if needed) I have also replaced the high pressure fuel pump on the rail. The only thing I have not done is remove the catalytic convertors. I will be doing that this evening. Any other advise would be helpful.

I have a 2010 Traverse. It has had a rough idle when cold since i bought it. 198,000 now. Started flashing the "running on reduced power" and missing real bad. I checked the coolant level and it was a little low in the overflow. I noticed white smoke out of the exaughst (just a tiny puff) when at idle while looking down at it under the hood. It shows steady engine light and misfire cyl #6 and #4 fuel injector leaking. Here is the deal- solution: Bad Block porased and leaking water into #4 cyclinder, that is where coolant is going. Leaks into cyclinder when car is off and fills up and causes the rough idle at cold startup. Replacing the head, or gasket will NOT fix this. The block could be tested by dyed coolant and a bore scope in the suspected cyclinder. Hate to say it but Chevy got me on this one. If your reading this...they GOT you too. Choose to buy a new engine... For now, I am straight wiring engine fans to run all the time and removing the seal around the radiator cap to keep the pressure down. Temporary to get me by, my only vehicle...
