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.

The contact owns a 2007 Chevrolet Suburban 1500. While placing fuel in the vehicle, the gasoline spews back out onto the contact. Also, the rear door opened automatically and the flip-N-fold seats flipped up and down while the vehicle was in motion. Lastly, the turn signals do not work. The contact took the vehicle to the dealer and they made her an offer; however, the contact refused. The vehicle was taken to the dealer on several occasions. The contact was aware of the safety risk involved. The failure mileage was 18,000 and current mileage was 25,000.
