| I purchased my suburban with existing gm warranty. the vehicle had roughly 47,000 miles on it and 7 months remaining of the original factory warranty. after about 900 miles the low oil light came on, which i thought was odd because i checked the oil life gauge after purchase and it said it was at 99% oil life. this worried me. it was one quart low so i added it and decided to see what happens. a month later at about 1000 miles the same thing happened. i added another quart and then went to the dealer closest to my home to report the issue. they started monitoring. each time at between 900 and 1400 the oil light came on and i was a quart low. they began remediation. first the pvc/valve cover remediation. this did not solve the problem. then next the oil pan related remediation. this did not solve the issue either. now i keep having to take the suburban to the dealer when the oil light comes on, they add a quart and say there is nothing they can do, from a legal stand point because i have an extended warranty and the car is out of gm warranty (remember i reported this while it was under gm warranty and reminded them of that), that gm won't do anything more from their experience with this issue. however, they have not contacted gm or opened a case file and wont do that. i was told i will need to pursue that on my own. they tried to reach out to my extended warranty but say they are put on hold for 10-15 minutes and have to hang up because they are too busy to wait longer. ive called them repeatedly asking that a case be opened with gm as this was reported under warranty and is a known defect with this engine (i'm out of warranty now) but they just keep giving me the run around. gm needs to do a recall and address these engines. | |||

| I have a 2007 suburban that consumes approx 1 qt of oil every 800 miles. at 1200 miles/qt the dealer told me this was normal consumption. i went to another dealer that confirmed the 800 miles/qt and is installing new pistons and rings next week. apparently this is not a fix but should help with consumption until a permanent fix is made by gm. | |||
