I believe this is a known issue for this engine due to the type of gasket. GM, of course, denies my assertion.
Also, the transmission had to be replaced under warranty at less than 6,000 miles.
The rear air conditioning condenser developed a leak after it was out of warranty so we just bypassed it and forgot about it.
Is it any wonder that GM is moving on to a replacement model?
