Frame failure on Infiniti Qx4 and Nissan pathfinder; model years 1997-2001. Frame failure on Infiniti and Nissan vehicles; failure in manufacturing to adequately protect from abnormal corrosion and rot, the frame, undercarriage and mounting brackets of Nissan and Infiniti SUV vehicles. Excessive corrosion and rot to front apron and frame of Infiniti Qx4 and Nissan pathfinder vehicles; suspect association with NHTSA recall number 07v435000. Insufficient protection of frame from abnormal and premature corrosion and rot; resultant catastrophic failure of frame while hitting a pothole at 10 miles per hour. Frame is broken above left front axle; tear is approximately 2 feet long and 2 inches wide. Frame areas around tear and throughout wheel and axle compartment are easily poked through by using a finger. Mechanic and body shop manager advise that vehicle is unsafe to operate. Repair costs for replacement of front apron of frame estimated at $3,000-$4,000. Nissan body shop reports that abnormal and premature corrosion and rot of frame are typical of Infiniti Qx4 and Nissan pathfinders pre-2003. Subsequent research finds consumer complaints related to model years associated with fuel line recall. Nissan does not reply to repeated requests for comment nor will it issue safety warning in relation to possibility of high speed failure of frame resulting in complete separation of tire from axle and frame; subsequent broken frame would travel through engine compartment and sever brake cylinders and steering. Grave possibility of loss of limb or life. Typical state safety inspections may not test frame integrity. Recommendation for advisory notice to be sent to state inspection stations and to vehicle maintenance and repair facilities.

While driving my 2003 Infiniti Qx4 on the highway, I noticed a severe vibration coming from the left side of my vehicle and tire. I took it to a local service repair shop and they took off my left front tire and saw where my inner apron was severely corroded, cracked and perforated. They stated they never seen such a type of corrosion in this area and that I should have the manufacturer look at it and take it to a body shop. 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. Pictures are available that were taken by body shop and I statement of serious safety risk of vehicle is also available from body shop.
