CarComplaints.com Notes: Engines shouldn't need a new quart of oil every 500-1000 miles, but for thousands of Suburban owners that's exactly what's happening. Engine oil consumption on aluminum block engines with Active Fuel Management (AFM) is out of control and owners are left looking for answers.
The most likely culprit is an uncovered AFM valve which, in many cases, can be covered under warranty. The problem is the issues don't stop there and many owners have been told by GM just to buy a new engine. Take one guess who they want to pick up the tab.

I actually go a speeding ticket when using the cruise control on my 07 suburban. I had it set for 68mph and thought that the cc would keep me at the speed. NOT SO, when I saw the red light behind me I looked at the speedometer and I was traveling much faster than 68mph. I remember thinking wow my ford expedition never allowed me to accelerates once I let the cruise control. I just figured it was the was it was designed (very poorly) but, now that i see a complaint here about the same thing, I know it is a problem that needs to be delt with.
