One problem related to engine exhaust system has been reported for the 2006 GMC Envoy. The most recently reported issues are listed below.
My GMC Envoy denali 2006 uses up to 2 to 3 quarts of oil in a 30 day period. I have no leaks or exhaust problems. It finally collapsed a lifter and push rod. Says there is no notice or recall, but the is the same engine they used in the 2003 pontiac, they did recall those motors. Does any one have some help for me?.
