problem #2

Feb 152020

Terrain SLT 2.4L Dohc 4 cyl

  • Automatic transmission
  • 92,210 miles

It was recommended by the dealer to have to clean the "moisture/sludge from the intake" "Cause: pcv system restricted and filled with excessive moisture". Correction: removed intake manifold cleaned pcv system, cleaned throttle body, installed new gaskets, and reinstalled intake manifold.

The above repair was an issue with 2010-2013 GMC Terrain's as well. GM Service Bulletin March 2015. Bulletin Number: 14882. Apparently GM decided not correct their flawed PCV designas mentioned in the previous models and continued to sell the new models with the same issue. Come on, GM you should be better than this. I have never owned a car with so many silly issues. You need to go back to making cars old school again. SMH.

Gm knows about this issue, has already agreed to fix 2010 to 2014 engines with this problem but not my 2015.
