I was talking to some guys at work about newer suburbans and they brought up some sort of active fuel management. I guess basically it shuts down some of the cylinders to conserve fuel and turns them back on when you need the power.

A buddy of mine at work told me this system is slowly tearing engines up.

Does anyone here know more details about this? We are seriously considering trading in the old 03 burb for a newer model but after reading what I have I'm not so sure I want to. Anything we get wont be newer than a 2012 TOPS.

Meanwhile I'm gonna read up some on it.

thanks
 
I've heard the same thing about that system being bad on the engines however, I've also heard that the dealer can deactivate the system basically turning the engine back into full-time 8 cylinders.

I haven't heard if that change elevates the engine problems or not.
 
I spent a few hours reading up on this.....not good.
Although not everyone has had problems, it seems like it was widespread.
From what I can gather the problematic years were between 2007-2009.
Oil consumption was a big issue, loss of combustion, and lifter issues were other problems.
Makes me want to reconsider getting a newer one now.....
 
Thanks for the research and the post! Every time I think of a new suburban, I run the pros and cons and am reminded that they just don't make em' like they used to. I like the newer transmissions, but then I'm reminded how much they are to work on. I like some of the new designs, and then I'm reminded they have no tailgate only a hatchback like a minivan. It goes on and on until I say..."they want me to pay $50,000 for THAT when it doesn't have as much as THIS?" At this point, if I got a new one I'd have to keep my old one too!
 
Hi guys!
Just wanted to throw out there that by no means am I trying to dissuade anyone from a new(er) rig. I just feel that WE as the CUTOMER need to be as best informed as we can be.
In my opinion GM installed newer technology that may not have been completely ready. Its a good idea but I feel still lots of bugs in system. They might be worked out by now, or this fuel management system might be able to be switched off completely. I do think its an option.
I also believe that GM was under a lot of pressure from the gvt. and some EPA guidelines for better mpg.
Again its just my opinion. I've always been a chevy guy and I always will be :)
PEACE OUT GENTS :cool:
 
I remember when fuel management meant putting it in neutral when going down hills!
