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 The dealerships will not honor a recall that is no longer valid or closed.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.

- What is wrong
- Nissan is recalling certain model year 1996-2004 pathfinder and model year 1997-2003 infiniti qx4 vehicles originally sold, or currently registered in, connecticut, delaware, iowa, illinois, indiana, massachusetts, maine, maryland, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, washington d.c., west virginia and wisconsin. In areas of the country in which heavy concentrations of road salt are used, a mixture of snow/water and salt may enter an assembly location hole in the upper strut housing, causing water to collect at the mating surface of the strut housing panel and the inner hood ledge assembly. Over time, this snow/water and salt intrusion may result in corrosion of the strut tower housing in some subject vehicles.
- Risk
- The strut housing may crack and pull away from the inner hood ledge assembly. This may lead to grinding noises, increased steering effort, and possibly the steering column to break, resulting in the loss of steering control, which could result in a crash.
- Remedy
- Nissan will inspect the strut housing and repair the vehicles as necessary, free of charge. An interim notification letter was sent out in may 2011. The second notice was mailed on july 25, 2011. Owners may contact nissan at 1‑800‑647‑7261.
Recall number 11V244000 · Recall details
Fuel system, gasoline: storage: tank assembly: filler pipe and cap
- What is wrong
- On certain vehicles originally sold in or currently registered in the states of connecticut, delaware, iowa, illinois, indiana, kentucky, massachusetts, maine, maryland, michigan, minnesota, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, tennessee, vermont, virginia, west virginia , wisconsin and the district of columbia, during the coating process of the fuel filler tube assembly, an insufficient amount of coating may have been applied at the lower mounting bracket. This could result in an opening in the coating which can allow water to enter and make contact with the bare metal of the tube.
- Risk
- This may result in surface rust but not perforation of the tube. However, in those areas of the country which use heavy concentrations of road salt in the winter, if a mixture of snow/water and salt makes contact with the bare metal, corrosion may occur to a degree which results in perforation of the tube. In this case fuel leakage may occur when filling the tank. Fuel leakage, in the presence of an ignition source, could result in a fire.
- Remedy
- Dealers will replace the fuel filler tube assembly with a new one with an improved coating process. The recall began on november 26, 2007. Owners may contact nissan at 1‑800‑647‑7261.
Recall number 07V435000 · Recall details
Electrical system: ignition
- What is wrong
- Vehicle description: passenger vehicles. These vehicles may have an ignition lock assembly with improperly seated key cylinder cap connector pins. Vibration can cause the connecting pins to loosen and/or fall out allowing the key cylinder cap to disengage from the key cylinder.
- Risk
- If this occurs, the steering wheel lock rod can move, which could lock the steering wheel, increasing the risk of a crash.
- Remedy
- Dealers will inspect the ignition lock assembly and assemblies with loose or missing end cap connector pins will be replaced. A ring clip will be installed on all others to prevent loosening of the pins.

Tl* the contact owns a 2000 infiniti qx4. The contact stated that the vehicle's frame was completely rusted and the fuel tank did not indicate when it was at full capacity. As a result, fuel would overflow. The rust failure was remedied in 2012. The vehicle was taken to infiniti of northern kentucky (1945 dixie hwy, fort wright, ky 41011) for other repairs; however, it was not diagnosed for the fuel failure. The manufacturer was contacted. The failure mileage was unknown.
Riding with a co worker coming from breakfast on veterans parkway,1st default was front axle,2nd default airbags didn't deployed,so I'm telling the driver to slow down cause of the axle he refuses and hit the guard rail doing 70mph hit 3 times before started rolling off guard rail.was hospitalized
Tl* the contact owns a 2000 infiniti qx4. The contact stated that corrosion of the strut tower housing caused the power steering column to fracture. The vehicle was taken to the dealer where it was diagnosed that the steering column was fractured. The vehicle was not repaired. The failure mileage was 195,000.
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
I was told about a recall on this vehicle due to frame body strut housing corrosion, I'm hearing a clicking sound as I proceed to make turns now. I took it in to be looked at to see if noise I was hearing could be repaired, upon the mechanic placing the vehicle on the lift he noticed the corrosion on front end of the strut housing.
Tl* the contact owns a 2000 infiniti qx4. The contact stated that while refueling the vehicle, fuel spewed back from the vehicle. The vehicle was taken to the dealer for repairs under the federal safety agency campaign number: 07v435000 (fuel system, gasoline) however, the vehicle was only inspected and not repaired. The contact stated that the dealer was instructed by the manufacturer to inspect the vehicles fuel filler tube assembly for coating and make repairs if necessary. However, the recall notice remedy indicated that dealers would replace the fuel filler tube assembly with a new one with an improved coating process. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 183,000.
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. Recall number: 07v435000 recall date: 09/18/2007 component: fuel system, gasoline:storage:tank assembly:filler pipe and cap problem summary: on certain vehicles originally sold in or currently registered in the states of connecticut, delaware, iowa, illinois, indiana, kentucky, massachusetts, maine, maryland, michigan, minnesota, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, tennessee, vermont, virginia, west virginia , wisconsin and the district of columbia, during the coating process of the fuel filler tube assembly, an insufficient amount of coating may have been applied at the lower mounting bracket. This could result in an opening in the coating which can allow water to enter and make contact with the bare metal of the tube. Consequence: xxx corrosion may occur to a degree which results in perforation of the tube. In this case fuel leakage may occur when filling the tank. Fuel leakage, in the presence of an ignition source, could result in a fire.
Based on my my mechanics advise I had vehicle inspected by infiniti dealer and learned that frame of the vehicle rusted thru mounting point of rf lower control arm and unsafe to operate. Based on my mechanics advise, I contacted infiniti. I explained them that this vehicle only has 136,900 miles and should not have rusted like this. I truly believe that infiniti messed up the metallurgy or used cheap steel to manufacture this car. Infiniti recited the several recalls like strut tower and filler tube rust and said there is nothing they can do. I like these vehicles to be looked at again for the severe rust issues that makes these vehicles unsafe and can cause accidents.
