For the second time in two years Stabilitrac Warning along with Traction Control and the check engine light came on. In June of 2013 I had to take my 2008 Avalanche into the local Northwest Montana dealer to fix the problem as mentioned in the first sentence. Diagnostic at $97. Engine PCV system-pulling oil out-replace with updated valve cover at $169. Replace all spark plugs at $128, wire kit at $152. System service and clean injectors at $130. Flush at $58. Labor was $466 and with a few odds and ends the total was $973.72. In August of 2015, while in Puyallup, Washington, I got the same Stabilitrac, Traction Control, and check engine light. Had to take it to the local dealer on a saturday as I had to travel back to Montana (over 500 miles) on a Sunday. Replace left valve cover ( PCV leak coming from left valve cover) at $150, replace all spark plugs at $80. Replace brake switch at $20. Oil change also. Parts were $278 and labor was $591 for a total of $978.97. My problem must be oil getting into the spark plugs I guess. I like my Avalanche, but I am seriously looking at the Ford 150. Not a happy camper.
