What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2003 INFINITI QX4, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Suspension
Reports naming suspension components — springs, struts, shocks, control arms and related hardware.
From owner reports, verbatim
2003 INFINITI QX4. CONSUMER WRITES IN REGARDS TO VEHICLE FRONT STRUT TOWER SEVERE RUSTS AND CRACKS RECALL ISSUES. *SMD *TR
THIS CONCERN IS INVOLVING THE R1109 RECALL ISSUED BY INFINITI. THE RECALL WAS PERFORMED SIX YEARS AGO, HOWEVER RUST, AND HOLES IN THE METAL ARE NOW VISIBLE. I WAS TOLD THAT BECAUSE THE RECALL WAS ALREADY PERFORMED, THERE WAS NOTHING THEY COULD DO TO ASSIST ME. THIS VEHICLE WILL SOON BE UNSAFE TO DRIVE.
Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
BOUGHT A USED CAR FROM A USED CAR DEALER WITH 1 PREVIOUS OWNER. IN 2011 A RECALL WAS SUPPOSEDLY DONE BY INDICATING "INSPECTED!" WHY WASN'T THE PARTS REPLACED?

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
THERE IS A PULSING FEEL IN THE BRAKES. HAVE CHECKED ONLINE AND REALIZED THAT IT SEEMS TO BE A COMMON ENOUGH COMPLAINT BY OTHER OWNERS. ON HARD STOPS THE PUSH BACK BY THE PEDAL IS HARD ENOUGH THAT THE BRAKES LOCKUP INTERMITTENTLY. THIS IS DIFFERENT FROM THE PULSING FEEL OF THE ANTI-LOCK SYSTEM. IT FEELS AS THOUGH THE ROTORS ARE WARPED. IT IS FELT IN THE STEERING WHEEL ALSO, AND INCREASINGLY IN THE VEHICLE IN NORMAL DRIVING WITHOUT APPLYING THE BRAKES. IT IS NOT THE TIRES WHICH ARE FASTIDIOUSLY KEPT NEW OMI. NO INCIDENT YET BUT I BELIEVE THERE IS A TREND THAT NEEDS TO BE INVESTIGATED. *TR
THERE WAS A SEVERE PULSATION IN THE REAR OF THE VEHICLE WHEN THE BRAKE WERE APPLIED. THE DEALERSHIP SERVICED THE VEHICLE OVER 20 TIMES. *JB
