Due to a faulty pcv design my vehicle experienced a rear main seal failure. It was externally cold. The same as in bulletin 14882. GMC states that my vehicle is not covered.
Fuel pump failure allowing gasoline into crankcase in large volumes. Rough idle, constant stalling, misfiring, fuel smell recirculating into cabin. Exact issue addressed by gm recall for my exact Terrain and equivalent chevy equinox with 2. 4 ecotec. Was told mine was not covered as it wasn't in correct VIN range though same make, model, year, motor, highly dangerous combustible issue matched. Dealer charged me $700+ for replacement/repair of fuel pump, both O2 sensors, fuel line, oil change to rid gas diluted oil. 2 days, 50 miles later, O2 code engine light comes on, erratic idling begins, power loss then stalls. Removed oil cap to smell and find gasoline mixed back into oil. Between 1/8 - 1/4 quart gasoline in the crankcase after 50 miles of driving! this after "repair" at "certified" chevy dealership; a dangerous manufacturing flaw gm acknowledged was a problem but I was told, " not on yours though, wrong VIN". Thank you for placing my loved ones in danger gm, refusing to fix your own recall, charging me over$700 to worsen the issue and place my family in greater danger.
