2004 Nissan Altima Owner Comments

problem #1

Jul 292009


  • 82,100 miles


My car has been experiencing stalling and is hard to start. I have had a diagnosis of the service engine soon malfunction on the car and it has been determined that it was the crankshaft position sensor. I had this sensor replaced in 2007 or 2008. The car has continued to have the same problem. Upon another diagnosis, it is the same sensor. I contacted Nissan and they stated that my car was not part of the recall but advised me to go to dealership to have a diagnosis done. Which I did and of course they told me the same thing that my mechanic had already stated. At the dealership, I was told that the original part which is plastic allowed oil to leak in and causes a burn out of the sensor so they changed it to have a metal fitting. When I contacted Nissan again, they still said that it was not a recall but an upgrade of the part. In my eyes, that is not an upgrade, that is a replacement of a defective part that they are aware of but are only addressing in certain vehicles. There are numerous complaints already on file and on the internet of people who are in the same predicament as I find myself in who have had to pay out of pocket to have this part replaced! I believe that this is a totally unfair practice that Nissan is doing and I am addressing my concerns to you and to Nissan directly in hopes that as a consumer, we could obtain some sort of resolution to this problem.
