 I purchased this 2014 Sentra SR a few months back and within minutes of leaving the dealership I noticed the Shutter/Shudder/Jutter whatever you want to call it. 3 Nissan Dealerships and 200+ technician driven miles later and they still can't come up with a fix. I contacted Nissan North America about a month ago and have been going back and forth with the rudest, most incompetent customer service agents ever. Not only are they impolite and discourteous, but they actually have the nerve to talk down to you like you're some kind of idiot. Anyways, I'll keep everyone here in the loop as this process plays out. In the meantime, AVOID NISSAN LIKE THE PLAGUE!
