One problem related to car stall has been reported for the 2007 Chevrolet Suburban. The most recently reported issues are listed below.
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.
