Two problems related to engine oil leaking have been reported for the 2007 Chevrolet Suburban. The most recently reported issues are listed below.
The engine consumes approx 1 quart of oil every 1700 miles. There is no oil leaking under the vehicle.
Since 2008 our Suburban has required oil servicing on average every 2 months. We took it to many dealers and was told we needed to be able to track the consumption somehow. I stated, can't you check when the oil servicing light comes on and was told no. Don't know why it consumes so much oil and it's not leaking.
