We don't have a lot of complaints on file for the Infiniti QX4 — feel free to add yours here. Probably because it's so old, no one bothers to post complaints anymore.
Although the 2003 Infiniti QX4 has the most overall complaints, we rate the 2002 model year as worse because of other possible factors such as higher repair cost or more problems at lower mileage. The most-reported problem is with the 1997 Infiniti QX4 for shaking from rear.
