Simple 5-minute Fix Excessive Oil Consumption, Oil Burning, Spark Plug Fouling And Disabling VCM - Simple 5-minute fix for Honda with 3.5L V6 Engine with VCM (Variable Cylinder Management).
n 2013 a class-action lawsuit was filed against Honda, 1.6 million vehicles between 2008-2013 had been identified having potential for high oil consumption and misfires due to VCM Operation on 3.5L V6 Engines. Honda extended the warranty for these vehicles but did not correct the problem. This did not include the millions of vehicles between 2005-2007 that also had the same defective issues and had owners complaining of repeated failure of costly motor mounts to VCM operation, damaged transmission torque converters, fouled spark plugs and excessive oil consumption at the rate of up to 1 qt for every 1000 miles. Honda claimed this was normal.
Took it to dealer because warning lights came on in dash. A mechanic there said he has replaced 100's of rings in the 3.5 engine. Honda said it was because of poor gas, even though we use same gas in all our cars including a 2003 Honda Accord with 248,000 miles with no problems.
When my ECO light comes on ( Engine drops to 3 cylinders ) A vibrating noise comes from the engine. The vibration goes away when you give the car the gas. The noise is very loud and sounds serious. I drove the 2012 model for two years and didn't have this problem. Took car into Honda dealer and the mechanic could not hear it. They said don't worry you have a 3 year warranty.
This is a problem in the 2013 and 2014. Every time the RPM hits 2000 the ECO - VCM kicks in and the car vibrates. You will not sense this in the test run. In traffic it is a nightmare. Do your homework. I sensed the salesman knew something was wrong, he said some people do not like the way it drives - but did not give me a heads up on the real issue. My sister has the 2013 pilot and has the same problem. This problem will drive you crazy.
