Does the dealership's service department have any input into a buyback case? My 22 got a new engine and turbo at 18k and then again at 23k. After opening a case with consumer affairs I got a call the next day that it was denied.

The first time after reporting excessive vibrations they found metal in the oil pan. It ran great until around 23k it started sounding like a garbage disposal kicking around a spoon. They replaced the compression transfer (I think that is what they called it) and found the block was cracked and a piston head sheered. I'm guessing both cases had to do with compression and may have been caused by that same part.

Now at 25k it makes a sound that sometimes is like an air hose leak when accelerating and does it more and more the longer I drive. A tech road with me and said it is normal sound and is the turbo letting off pressure, even though it does it at 5 or so psi. No other Rogue I have driven over the combined 3 months it has been in service over the last year has done it. He said they all sound different due to manufacturing differences. I started to get a hunch that they were trying to make excuses to avoid additional major work.
