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 8-cyl

  • 73,510 miles


Our vehicle started to use between one quart and 2 quarts between oil changes. At sometime before this the heater stopped working on the windshield washer fluid. The dvd player stopped working around 75,000 miles. At 79,0911 miles the service air bags light came on. We are not new to owning Suburban. This is our fifth one. We have always been happy with them, but this one has way to many things that are not working properly. We would like to hear from you regarding resolving these issues.
