Hey all, new to this forum but at the same time I share a lot of what I've been reading! Here's my story. We bought a 2007 suburban 5.3 AFM used about 4 years ago. It ran perfectly, with the obvious Chevy issues such as a transmission shift "flair". Oil consumption sucked about a quart of oil every 600-800 miles...but only really noticeable on highway trips. I think the AFM was definitely to blame, and after inquiring and submitting to dealership, they said it fell under "normal" category. After researching online, it most definitely was the AFM and GM had since put a shield to help reduce the oil consumption.
Anyway, I stayed on top of the oil consumption to make sure that there was always fresh oil in the engine. Then, one day about 3.5 months ago, blinking lights, stabilitrack failure, check engine, etc etc all hell breaks lose on the highway at 65mph. I immediately pull over. Fast forward to now - all said and done, after two diagnoses by independent mechanic AND chevy dealership, I have a flat camshaft lobe that causes the misfire, which then causes everything else to go awry in the computer system. Long story short - I need to rebuild or replace my engine. WTF?? And it's only a matter of give or take $500 difference to buy a new engine installed than it is to rebuild it. So rebuilding it is out of the question.
I pursue GM in good faith, as my family and I have always been GM people. I ask for some type of assistance as I'm out of warranty but an engine with 95% highway miles should last longer than 160k. I get the same type of runaround for nearly 3 weeks, waiting and waiting dfor a call back from the rep. I'd call every other day to touch base as I hadn't heard from her, and then finally called back to speak with another rep only to find out that the orginal girl had closed the case, stating that she couldn't get a hold of me. Um what? I called many many times , leaving the correct phone numbers to reach me, including email address! It was an obvious brush off. I couldn't believe the complete and utter disregard called "customer service". It's one thing to say no, but another to blow me off. I'm still pissed, and as I write this being a business owner myself, my mind is still blown how someone could be so blatantly rude.
I spoke with another rep and she elevated the case to a specialist, who then couldn't help me and pointed me to the "touch point' specialist - which is my dealership!!!! WHAT? All this rigmarole to just end back up where I started - where my suburban had ben siting for nearly 3 weeks! Oh, and then they say that they can't help me with the engine, but offer $500 off the $7,000++ cost to replace it.
GM Customer service is a JOKE! I don't know how any business, big or small, could survive with such BS. Thank God GM took my tax dollars to help stay in business, eh?
So where do I stand? With an expensive decision to replace the engine with either a GM engine or a Jasper engine. Meanwhile, my pregnant wife (now just had our 3rd baby!) is waiting to have her car back. Do any of you have any suggestions on which ave to pursue with either engine? Experience, opinions etc?
New GM engine or Jasper engine?
Great to hear - time to head for Colorado again!

I have an '02 Surburban that has a rough idle on cold start. Typically, the temps have to be 40 degrees or below for this to occur. It never happens during the warm spring, summer and fall months. I replaced the fuel filter last fall and was told at that time by the local dealer that my burb has a flex-fuel motor and that this was a bit rare for this year model. At times, the check engine light will activate during the rough idle. Sometimes the light flashes and goes off after a half hour or so, and sometimes it will come on and stay on for as much as a day or two. The burb always runs fine after warming up, even if the light stays on. I have attempted to have the code pulled when the check engine light comes on, but the last two times, nothing shows up. Anyone have advice for me? The truck runs great 85% of the time.
