2007 Chevrolet Suburban LT 1500 4dr SUV 4WD (5.3L 8cyl 4A)
Consumes 1.5 qt of oil every 1000 miles since 47,000 miles. Have to take to dealership every 1000 miles for oil consumption test to get GM to warranty if they ever find a fix. They were supposed to have a fix Feb. 2009, now it is July 2010 and still no fix. Have a friend with a 2009 Suburban with same problem. Also have had battery drain problems.
