Chevrolet Suburban owners have reported 3 problems related to crankcase (pcv) (under the engine and engine cooling category). The most recently reported issues are listed below.
Excessive oil consumption. I see this is a common problem on gm vehicles and it affects both my 2011 Suburban and 2012 silverado with 5. 3 flex fuel engines. The Suburban is more noticeable since we use it for long road trips. The truck is mostly city driving. I believe this to be caused by the afm and pcv. I will be installing the upgraded valve cover in hopes of preventing a major engine failure in the future. It would be nice if gm recalled these engines with an adequate fix. I only notice burning oil on startup coming from the exhaust. Current mileage on the Suburban is 104,000. I have not touched anything in the engine bay or cable covers yet. Please respond quickly if I should not. Thank you, [xxx] redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Last year 2012, the Suburban was blowing smoke out tailpipe, less than 100k miles, so dealership installed new valve cover with proper grommit for pcv under warranty. Sept. 2013 115k miles, engine bucking, dash lights all on, running on 7 cylinders, chevy dealership states #1 spark plug "came out". And that oil pressure sensor was bad, but still pressure, so not urgent. . . . Nov 19, 2013 - truck now making 'back fire' noises and pressure sensor moving back and forth across 40. . . . Afraid will break down again. Also, have peeling chrome on inside door handles like prior complaint, that is cutting hands/fingers!.

Have 2002 Chevrolet Suburban 1500 4wd 5. 3 engine a/t. Was driving 45 mph when vehicle suddenly stalled out & lost all steering/brakes. 131,589 miles on odometer at time. Managed to coast vehicle onto shoulder, waited 2 minutes, started vehicle again, pulled out into busy traffic just to make it 2 blocks before stall out again. Repeated this process several more times before I found a gas station. Suspecting water in gas, added 1 bottle of gas line anti-freeze. Drove rest of way home without incident. Replaced fuel filter, pcv valve, air filter, spark plugs, and cleaned throttle body just to have stall out the very next day. No codes are displayed in message center in dash board. Stalls out randomly without a pattern. Wait 1-2 minutes then will start again.
