What 2000 Infiniti QX4 owners say
Body & structure
The vehicle is completely rusting underneath and running boards. I was told by Infiniti customer affairs that the recalls had closed for rusted out struts. This impacts driving and can become a safety concern if the struts completely rust away. I'm concerned for my safety or the safety of my family if this failure occurs. The dealerships will not honor a recall that is no longer valid or closed. This is a potential life safety issue.
Serious corrosion on the frame. The passenger side of the vehicle where the control arm attaches to the frame is completely rusted out just beyond the strut mount recall location. The dealership deemed it not able to be fixed and was told by both the dealership and consumer affairs that its not their problem. While driving 55 MPH I started hearing a knocking noise in the right front. Soon after the wheel started shaking while turning left. Knocking got worse and it started to sway uncontrollably while turning. Had it towed to dealership where it is still sitting and not able to be driven. Updated 08/29/2017

My 2000 Infiniti QX4 had a visual inspection done at the Infiniti of bellevue wa on aug 4, 2008 and determined that there was enough coating to prevent corrosion from occurring due to a recall. The vehicle is now leaking fuel during fill ups and when it is topped off. A visual is not an acceptable practice of measuring thickness of a conversion coating. The dealership verified the issue on October 27 2015 and the Infiniti corp will not honor the recall because it does not want to open the recall. This is an extremely dangerous issue when fueling the car it is spilling on to the ground at the gas station and could ignite. There is numerous complaints about this fuel filler and a lack of product to fix it. Due to this inadequate inspection the safety of the public has not been achieved, the recall should be reopened. …
