That's what they are saying to the gullible that will believe. It's really a desire to pinch penny's at the customer's cost, and to help push vehicles back into the dealership for service (or preferably a trade in and new vehicle purchase). That's a win/win for them (unless the owner goes over to brand X, which must happen a lot). They make a new sale, and pick up an otherwise good vehicle that they can flip cheaply on their lot. In their mind, if you buy a new vehicle every 3 or 5 years, you won't have these problems.
