One problem related to engine exhaust system has been reported for the 2009 Infiniti M35. The most recently reported issues are listed below.
I purchased an 07 Infiniti M35x and had several issues with it. The major issue was due to a "dragging, rasp rattling, rocks in a can sound" coming from underneath the car; which I fought with the dealership on for over a year. Since then; I worked a deal with the new and current gm on a 09 M35 sport and the same rattling has aroused again; "rocks in a can" sound coming from the car after putting just a couple hundred miles on it. I brought it back to the dealer on July 8th; in which they kept it for 3 days. Changed out the installation and heat shields; the problems is still there. There are an abundance of reports on the internet about this; with dealership tech's giving customers different opinions about the issue and even admitting it to be a known problem. The issue gets worst over a period of time and as the system gets hotter and hotter. I'm afraid that at some point with me driving this new vehicle; that something could possibly go wrong while driving on the highway and cause a major accident. Vehicle location in the virginia beach area currently.
