Re: Nissan Warrenty compliance?
Wee, I didn't say that the warranty requires the mfg. to do it the scheduled maintenance. I just said that it had to be done. If your car has an oil related failure and you can't prove that you (or jiffy lube, your dealer, etc) did regular oil changes, then the mfg. has the right to deny the failure as a warranty problem. Now, if you change the oil yourself, and you have a oil warranty failure, you might have hard time proving you actually changed the oil as per the mfg's recommended schedule. Yes, you can show the receipts where you bought the oil but that doesn't prove that you actaully changed it, nor do you have any proof WHEN you changed it. But by having it done by Jiffy Lube, etc you would at least have a receipt proving (a) it was done and (b) the invoice would show the odometer reading when it was done.
As far as having an ECM failure and then having someone turn down the warranty because you didn't change your impeller...that wouldn't happen with any mfg. Companies put out a warranty to give the consumer peace of mind and to protect themselves as well. I think stating that a company would turn down a warranty on one component because you didn't do something to some other completely unrelated component is a total stretch on your part. That's like saying the Ford would turn down a transmission problem because you didn't change the air filter.
