excessive oil consumption
By jjohn22 on
2007 Chevrolet Suburban LT 1500 4dr SUV (5.3L 8cyl 4A)
Around 36000 miles I noticed our suburban started consuming 1 quart of oil per 1000 miles.
Over the past 2 years I have had the dealership try various "fixes" but it still consumes oil.
This is becoming a trend with the '07 suburban as others are experiencing the same problem.
My vehicle will be at the dealership for a week for the next round of exploratory surgery on the engine.
Hopefully they can find a fix as I am running out of powertrain warranty in a few months.
The first 2 years with this vehicle we had repeated electrical problems with battery discharge.
GM found a fix for that.
We bought this model for our family vehicle because of its generous size and comfort on trips.
Major problem with oil consumption and electrical problems causing repeated battery discharge.
To date there has been no GM fix for the oil consumption.
It will be back at the dealership next week for the 3rd round of tearing down the engine.
For all this effort it would have been more cost effective to just replace the engine.
GM customer service is not much help...they call every few days to ask "is it fixed yet?"
They act more as customer pacifiers than problem solvers.
