Beware of the Nissan warranty! My Nissan Titan is a 2018 with 72K miles and has a so-called 5 year 100K bumper to bumper warranty or so I thought. I have had an issue with the fuel tank whistling extremely loud since day one. During my first oil change where I purchased it, I told the salesman about the issue and he just laughed and said they all do it. About 6 months later I was at another Nissan dealership getting my oil changed and I showed the service guy a video of me filling the tank and he said I have never heard of that before and there is no info about your problem. A year later they came out with service bulletin NTB19-049 about my issue. I was getting my oil changed this past month at a different Nissan dealership and I asked the service manager there about my issue and he knew immediately about it and said he would see about getting it fixed. He found out that repair is considered a DEFECT and is only covered for 3 years and 36K miles. I escalated it up the ladder and they agreed to pay 1/2 of the cost.... what a joke! How in the world do you determine what is a defect and what is a normal repair. I am a 4 time Nissan owner and I am looking to trade my Titan in today on another vehicle. This is the last time me or my family will purchase a Nissan vehicle.
