My dealer told me today (this is the second time my x 4X2 has been in the shop) that they couldn't find anything wrong with it, even though they heard the chuncking noise when the vehical comes to a complete stop. They called the technical support in california who told them it was a "characteristic" of the 4X2's. PUULLEASE. The dealership doesn't know how to fix it and Nissan doesn't know how to either. I am taking it to another dealer if anyone has any suggestions my appointment there is not for a week! This has been going on for about 3 months now.
