Hi. I went to the Nissan Dealership & what I thought was a defect on the drive belt it turned out to be a normal appearance of it. Anybody aware of these type of newer drive belts. The Service Advisor at Nissan said that's how they are now & if they were to replace the drive belt it would look identical to the one already on the car. I thought it was an imperfection but apparently, that's how they are now. Anybody else knows is this is the case. Here are some pics.
