I KEEP GETTING NOTICES ABOUT THIS AIRBAG RECALL, BUT THIS VEHICLE WAS DONATED TO HUDSON HIGH SCHOOL AND BROKEN DOWN FOR PARTS. THIS VEHICLE HASN'T BEEN ON THE ROAD FOR OVER 3 YEARS. PLEASE TAKE THIS OFF THE RECALL LIST.
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?
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.
THE CONTROL ARM IS COMPLETELY RUSTED AWAY AS THE PATHFINDERS THAT THEY RECALLED AND IS DOING EXACTLY AS THEY HAVE DONE...BUT THERE IS NO RECALL ON THE INFINITI I WAS WONDERING WHY THOSE AND NOT THE INFINITI AS WE LIVE IN MASSACHUSETTS AND THE SALT DOES THE SAME ON THIS CAR NOW WE HAVE THE DEATH WOMBLE ON THIS CAR

THE SUV WAS WELL TAKEN CARE OF, 1 OWNER, AND THE FRAME RAILS AND CHASSIS ARE CONSIDERABLY RUST FREE. HOW COME THESE ARE IN SUCH BAD CONDITION? WHY DON'T INFINITI HAVE REPLACEMENTS FOR THEM ALONE AND NOT THE WHOLE RUNNING BOARD FOR OVER $1300 PER SIDE! THAT'S INSANE AND NO ONE IS GOING TO PAY THAT FOR A 11+ YEAR OLD SUV! *TR

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

THEY STATED THAT THE VEHICLE SHOULD BE REPAIRED AS SOON AS POSSIBLE AS IT WAS A SERIOUS SAFETY RISK AS THE STRUT TOWER COULD DISLODGE AND COME UP THROUGH THE HOOD OF MY VEHICLE WHICH IS CLOSE TO MY BRAKE LINE AND COULD AFFECT MY STEERING. I DID TAKE IT 2 BODY SHOPS BOTH OF WHICH CONCURRED THAT THIS TYPE OF CORROSION SHOULD NOT HAVE HAPPENED AND THEY ALSO STRESSED IT WAS COMPROMISING MY SAFETY AND THERE COULD BE A SHIFT OF MY SUSPENSION AND LOSS OF CONTROL OF MY VEHICLE WHILE DRIVING. I DID CONTACT INFINITI SERVICE DEPARTMENT AND IT WAS ONLY GLANCED AT NOT INSPECTED. I FILED A COMPLAINT WITH INFINITI CONSUMER AFFAIRS AND WROTE A LETTER TO THE OWNER OF CLOSEST DEALERSHIP. I WAS THAN ABOUT A WEEK LATER ASKED BY THE LOCAL DEALER IF THEY COULD LOOK AT MY SUV AGAIN AND PICTURES WERE EMAILED BY BODY SHOP TO THE SERVICE DEPARTMENT OF DEALERSHIP AND SENT TO CORPORATE AND MY REQUEST TO HAVE THEM REPAIR VEHICLE WAS DENIED AND I HAVE HAD VEHICLE REPAIRED AT MY COST AT LOCAL BODY SHOP.

The basics
How to read this data
Complaints, recalls, investigations — here’s what each number actually tells you about a used Infiniti QX4, in plain English.
What is an NHTSA Complaint?
An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is — but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The Infiniti QX4 has 167 complaints on record across 4 model years.
What is a Safety Recall?
A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The Infiniti QX4 has 17 recall campaigns in the NHTSA database.
What Are Crash Complaints?
Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 15 of the Infiniti QX4's 167 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions — a key safety signal beyond general reliability.
How Is the Reliability Verdict Calculated?
The reliability verdict (Poor) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. This verdict gives buyers a quick interpretation before they review year-level details and VIN-level history. It should be treated as one decision input, not a substitute for a VIN-specific report.
Why Do Newer Years Have Fewer Complaints?
Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable — simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.
Fleet Data vs. Individual VIN
Everything on this page reflects aggregated data across all Infiniti QX4 vehicles on the road — not any specific car. Two Infiniti QX4 vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.
What Are NHTSA Investigations?
When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage — NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The Infiniti QX4 has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
