Hello. I have an 09 Titan that has been shaking since the first week I had it(9 months ago). I have been through 2 dealerships, 12 service visits, 4 tire balances(other than normal), 2 alignments, the leaf spring shims, and an entire new drive shaft assembly. I am currently going through the lemon law process in New Jersey and have been about for about 8 months now. If you are having any problems with your Titan shaking, please let me know. You can email me on here or at Titancoastie@gmail.com. A Nissan service manager slipped and told me that Nissan knows that there is a problem with the Titan's shaking, but does not have a fix yet. They evidentally do not want the people with the trucks to know about it, so they are telling the dealerships to tell the buyers that it is either a normal vibration, or to deny being able to duplicate it. If you have any of these problems, or know any solution please let me know. I am trying to get together a list of as many people as possible to give to my attorney so they can take it further and try and blow this problem up.Thanks!
