It looks like I am in the same situation as everyone only I have not had my car in 28 days. We purchased our Pathfinder in May of this year and loved it at first. Then we started having the shuddering issues. I at first thought maybe it was the road or the car just needed to be driven awhile since we only bought it with 6 miles on it. Then it started getting worst. We took it in an the service tech stated they were seeing a lot if these issues. He told me that they would first reset something in the transmission, then if that didn't work the torque converter would have to be replaced and if that didn't work the transmission would have to be replaced. So the following week later I called in to get status and I was told the torque converter has to be replaced BUT the part is back ordered and they have no clue when the part would be in. It has been 28 days without my Pathfinder and I have had to make a car payment while its in the shop waiting for the part. Not to mention the payment I made in August and only had the car for 15 days that month. It is so frustrating to deal with Nissan. The local dealership has not offered anything yes I got a rental but when I said I wanted something else done all they said to call Nissan Corp and file a claim. I did that and have only got a message stating they are looking into it. You would think with this problem happening to so many they would be able to fix the problem fast. In my case I feel Nissan is doing nothing from the local dealer to the corporation. I regret getting this Nissan due to their lack of customer service and how they are dealing with this issue. I do not feel safe taking my 3 children this car not knowing if it going have anymore issues. I am just so frustrated and do not know what to do!!!
