Consumer Description

Engine is consuming 3qt oil every 1,000 miles. Has been consuming oil since 34,000 mile mark and the transmission has been slipping where it revs very high before downshifting. GM has asked for an oil consumption test to be done and now we are 9,000 plus miles into it and they still say it's fine. This car is not worth the price. I can't even take it out of town due to needing the oil consumption every thousand miles by GM request. Complained about engine knocking at 22,000 miles and they said it was normal and I know it's not
