Thanks fastdriver. Sorry to hear that your experience was not a pleasant one. I feel that I am in a position to have some patience for various reasons. First, I am going to step back and take a look at this issue, not only as a consumer, but as an outsider. I want to give GM the opportunity to take care of their customers and show that they are doing something to help remedy the problem. I am trying to take an approach that is patient, but yet exhausting all the resources I have available with GM and my dealership and placing accountability where it should be. I am choosing to post my progress on this thread so everyone can see the approach I took and GMs response. I understand that others have been here before me without the best results. I am hoping that something will surface to benefit not only me, but everyone thorough this process. I am not looking for an immediate fix at this moment as I understand this issue is quite complex. But I am looking for progress, updates, and eventually a permanent fix. GM owes that to all of us. I know this thread has been a valuable tool in helping me work thorough this process. I do think someone realizes "GM, we have a problem" and they have returned to the drawing board.I applaud you for your patience in dealing with this issue!
OK Gina, no need to get upset with us. This is a free internet forum full of very helpful people. If you come here with a problem and get anything positive at all out of it you are ahead and it didn't cost you anything but your time. If you get nothing out of it it didn't cost you anything but your time. Even if we DID know what was wrong with your car and how to fix it, there's nothing we could do about it... you are still at the mercy of your local dealership and/or anyone you can get on the phone at GM.Thanks for your support, sounds just like what I get from General Motors.
There's actually a software update that is supposed to cool off the turbocharger with the engine fan once the engine is shut off.Blue Angle, excellent analysis. Given the service bulletins you reference, it appears as though GM has observed this issue and maybe devised a fix that will impact our coolant issue. I am scheduled to bring my car to the dealer on Monday and I plan to discuss this with the service manager. Thanks for your very helpful post.
Please let us know more about this update! If you can get a TSB # from your dealer and any kind of indication which years/builds of cars are affected that would be GREAT!There's actually a software update that is supposed to cool off the turbocharger with the engine fan once the engine is shut off... ...This software package also has other benefits to it (like improved acceleration smoothness when the engine is cold). I should be having it done to my car soon, and I will fill the tank back to the proper level and see if it makes any difference whatsoever.
I have no idea... if someone else knows how to look up the full version of a TSB please let us know. It appears that website only offers part of the title, but none of the meat and potatoes of the TSB itself. Maybe talking to a service advisor at your dealership would work if you already have the TSB#?How is one to determine if they need the Service Bulletin 339360 for Chevrolet ENGINE AND ENGINE COOLING | AutoMD ?
Well, it would seem so far that most of the people experiencing this issue are simply driving down the highway with the heat on... I would have thought that scenrio was well covered in their development!I still believe the crux of the problem is that the ECM and its software can't manage the temperature properly. I believe that this design was targeting maximizing gas mileage and lowering emissions. The side effect is that the motor just gets too hot at times. It depends on the driving environment and the engineers weren't able to predict (or test) all possible combinations of inputs. If that is true, they may take a very, very long time to come up with a fix for this design.

Finally the whole text! Thanks!CHEVROLET: THE OIL FEED PIPE NEEDS CHECKING AND REPLACED. IF RESTRICTED, AND TURBOCHARGER ASSEMBLY SHOULD BE REMOVED AND REPLACED, AND THE ECM SHOULD BE VERIFIED FOR LATEST CALIBRATION TO ALLOW TURBOCHARGE TO COOL, TO REDUCE LIKELIHOOD OF OIL COKING OIL FEED PIPE.
