Structure: body: hatchback/liftgate: hinge and attachments
- What is wrong
- Vehicle description: sport utility vehicles. Some of the brackets used to attach the two gas struts to the rear door (hatch) may have been improperly made. At high ambient temperatures, the increase in gas pressure in the strut(s) could cause one or both brackets to bend, resulting in the struts detaching from the bracket(s) when opening or closing the rear door.
- Risk
- If both struts detach from the brackets, the door will rapidly fall down, possibly striking someone and causing serious injury.
- Remedy
- Dealers will replace the strut brackets. Owner notification began september 24, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact nissan at 1‑800‑647‑7261.

What 2001 Infiniti QX4 owners say
Most recent owner complaints, unedited.
The SUV has been recalled for unusual rusting of the entire underside, the federal safety agency said the struts may rust and break away from the body, that is happening. We called the nissan dealer in winchester virginia, they lied and said there is no such recall.
Tl* the contact owns a 2001 infinti qx4. The contact stated that the frame was rusted on the vehicle. The vehicle was taken to a local dealer (infiniti of akron located at 3332 s arlington rd akron, oh 44312), but was not repaired because the frame needed to be replaced and was not covered under the recall remedy. The manufacturer was made aware of the failure, but was unable to offer assistance. The recall details were not provided. The failure mileage was 154,000.
Tl* the contact owns a 2001 infiniti qx4. Upon inspecting the vehicle, it was noticed that there was severe corrosion of the frame near the strut on the driver's side. The contact took the vehicle to an independent mechanic where it was repaired. The contact was reimbursed. Shortly after the repair, the same failure occurred on the passenger side of the vehicle. The vehicle was taken to the dealer where it was diagnosed that there was corrosion on the passenger side. The vehicle was serviced per the federal safety agency campaign number: 11v244000 (steering, suspension) but the remedy failed to repair the vehicle. The contact stated that the frame continued to corrode after the recall repair. The contact stated that the recall repair did not adequately repair the failure with the excessive corrosion. The manufacturer was notified of the failure. The approximate failure mileage was 120,000.
Tl* the contact owns a 2001 infiniti qx4. The vehicle was taken to the dealer for routine maintenance. While being inspected, the technician found that the frame and underbody were corroded on the front passenger side. The contact was informed that the vehicle was unable to be repaired since it was structurally unsafe. There was considerable corrosion to the frame of the vehicle and could collapse while being lifted. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 201,000.
No accident. Discovered severe corrosion localized on passenger side frame/axel/front wheel drive bracket part of frame. Car has only 65,00 mile. Body, exhaust etc. Show no corrosion. Other parts of frame look mild. Car unsafe to drive. Nissan non responsive. I am original owner. Car was 7 years in ohio and 8 years in south carolina. We were lucky to find this before a significant incident!
Body frame rusted behind the front wheel on passenger side. When I try to replace the flat tire , the car collapse over the jack. The car frame broke.
The built-on running boards (these are not an add-on feature to the vehicle, but came standard on all qx-4s) have brackets and a tubular steel support beams that support the weight of any passenger stepping on them to enter the vehicle. The support beam and support brackets have entirely rusted away; there is little to no other rust on other areas of the vehicle. A local body shop identified and notified the owner of the danger associated with non-supported running boards. A consumer could easily be injured if stepping on the running boards to enter the vehicle and having them collapse. The injury certainly could be more acute for elderly, disabled, or children in the event of a collapse. The tubular steel support beams and brackets have no rust inhibitor on them while the other metal sections of the running boards were coated with rust inhibitor and show no rust. There was a design flaw either associated with the type of metal used or a lack of rust inhibitor on the parts that have disintegrated. The cost to replace is quite exorbitant and the replacements may have the same design flaw. The short term solution has been to entirely remove the running boards off of the vehicle to eliminate the danger. This makes for a tall vertical step-in, but is less risky then the faulty running boards.
I believe the car's running boards are a safety hazard due to serious rust damage causing weakness of the underlying structure. The hazard can manifest itself as the running boards can easy fail and the driver or any passenger can fall as a result. This is a common problem for qx4s from model years 1997 to 2002 or later. Obviously, it is worse for older cars in area's where salt is used on the roads in winter. I petitioned inifiniti to investigate the hazard and consider rectifying it. They claimed rust damage was not covered and would do nothing. However, I note they in fact had a strut housing recall for our qx4 to fix rust damage.
Tl* the contact owns a 2001 infiniti qx4. The contact stated that the brackets supporting the running boards were completely rusted. The contact stated that when a passenger entered the vehicle, they were unable to step on the running boards to assist entering the vehicle. The contact took the vehicle to the dealer and was told there was nothing that could be done to repair the running boards. The failure mileage was 70,000. Failed aprox 3.5 years ago. Unsupported running boards are a safety hazard. Updated 10/19/2011 *ln
