 The timing chain broke at 60k miles. Nissan said they wouldn't honor the warranty that I paid extra for. They said that the timing chain was a design flaw but that since I started taking my car to another business for oil changes(even though I had records of EVERY SINGLE OIL CHANGE BEING ON TIME, on a computer from the other business that millions of people use to have their oil changed, Nissan still wouldn't honor the warranty because they said the oil may or may not have been a bad "batch" at that business! How absurd! They wont honor the warranty because the engine costs 9000 dollars to replace and they dont want to pay for it even though its their timing chain design flaw that broke.
