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.

Suburban 4WD 8-cyl

  • 65,000 miles


My two children and I where coming home from a wrestling tournament traveling on a highway doing about 65 mph. They were in the back seat. We all had seat belts on. I had a epileptic seizure and they said my foot hit the throttle so we might have be going faster when we hit. I last recall doing the speed limit. I went to the left and missed a power pole but hit the railroad tracks(these tracks are banked up on dirt and rock). Which caused the Suburban to some how roll 4 to 5 times down the tracks.we ended up on the other side of the tracks on our rims. Every tire was blown. Every window was shattered except the front it had a hole in a center of it which a railroad tie came thru. There are impressions of the railroad road tracks on the Suburban. The driver side of the Suburban is smash down to the driver head rest. I ended up with a broken neck. Thank goodness my kids seats were reclined in the back or their necks would have broke. Not one part of this Suburban is not smashed. Everything flew out of it when we rolled. My son had to crawl out the window and search on the ground to find cell phones that flew out of the Suburban when we wrecked to call 911. The side air bags failed my family. I always felt safe with them. But we rolled and they did not work. Even the front airbag didn't go off when I first hit the tracks. Besides my broken neck it all turned out good. I will never buy a Chevy again. Our insurance company said our Suburban is totaled. Only thing worth anything is maybe the seats. Everything thing else is scrap metal. If you'd like to see pictures your welcome to contact us. But please check into these Suburban. If we wouldn't have had seatbelts we would all be dead. My husband went and bought a 2015 Ford. I will never put my trust in a Chevy again. Or airbags. I'm wondering if they just put a airbag sticker in them to make us feel safe. Thank you

I would like to call your attention to an accident that happened to my 17 month old granddaughter. In attempting to steady herself while walking, she accidentally touched the tire on my daughter's Chevrolet Suburban. Her small hand slipped through the hub cap space and came in contact with the hot brake pad, causing her to suffer 2nd degree burns on the palm of her hand. It is my belief that this must have happened to other young children. Parents with whom my daughter and I have spoken had no idea that brake pads were so accessible. I am concerned that the public is not aware of this danger and should become aware as soon as possible.
