Print this page 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.

"takata recall" GM tells me that I just have to drive my defective vehicle until they come up with a repair. I also have a cracked dashboard which I think has something to do with the airbag.not safe for my family of 5. I spent $60,000 for a potential death trap!!! suspension light on and dealership wont tell me what is wrong.

I just got a call today from my mechanic and he told me that the whole rear axle had to be replaced and if I don't replace it I could have an accident. What can I do to get this replace at no cost. Is there a recall for this "??"
