2007 Pontiac G6 experienced oil-leak from front-crank and oil-pan areas. Gaskets had to be replaced. Mileage when first noted was 20,000-miles. Dealer scheduled appointment and performed replacement as needed. Warranty-work.

Service traction control warning appeared followed by engine, oil and others with 'reducing power to the engine' warning. Then dropped to no rpms and engine stalled -unpredictably.
