Excessive Oil Consumption
2007 Chevrolet Suburban (Page 3 of 10)
This problem may be covered under warranty. Ask your Chevrolet dealer.
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.

- 2 Fixes To Suburban 5.3 AFM Excess Oil Use - (1) First <1 hr fix is changing the driver's side engine valve cover with the improved-design driver's side valve cover with the square PCV hole moved back (from the original circular PCV hole that is too far forward and siphons AFM-splashed oil). (2) Second fix is disabling or removing AFM which causes the excess oil splashing with either a custom pro-shop engine tune, a Range Technology AFM Disabler Device (https://www.youtube.com/watch?v=FQUAh5pTjIA) or an expensive replacement of AFM engine system hardware.

This vehicle has been a lemon since I bought it brand new. Have replaced bearings, replaced, brakes 3 times already, and uses oil like crazy. I had the transmission fixed twice which was actually covered under warranty. Continuous stabilitrak problems, sometimes it only runs 35 mph and revs RPM's out of this world. We have been smelling gas and today a mechanic told us it has a valve problem that is causing the engine to leak gasoline and will be another 1k to repair. 4 of the 5 interior door locks don't work, the rear defrost wires have fallen off, the rear windshield wiper pump sticks and leaks out all the fluid in storage, and the back exterior lock has fallen off and is lost somewhere in Texas. Oh yea and we have replaced 3 gas caps because it has trouble sealing the gas tank properly. This is my 5th Suburban or Yukon product and when you pay 56k, you expect it to work. If this is the new GM, I have bought my last.
