I had my 2013 1.4T 6M Cruze with 55,000 miles in for an oil change and tire rotation today. The dealer claims that my oil pan is leaking and needs to be resealed, for a cost of $546.56. What makes me suspicious is that my garage floor has no oil spots on it. I asked the service writer how that can be, and she told me that it only leaks when it's running, and the leaking oil goes out onto the road. But I check my oil at least twice a month (always have). And it's always full. Can anyone tell me how my pan can be leaking but my engine stays full of oil and doesn't leak on the floor?
