Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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. …”
NHTSA complaint #10472000, filed 2012-08, 45,000 miles“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.”
NHTSA complaint #10578085, filed 2014-04, 152,000 miles“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. …”
NHTSA complaint #10550656, filed 2013-11, 137,095 miles“Corrosion in the front drivers side strut tower housing in front wheel area -body shop informed me it was a manufactureres defect. Cost me about $5,000 to repair. I still own the car.”
NHTSA complaint #10417774, filed 2011-08“My complaint is with the 2001 Infiniti QX4 that I have owned for several years although it has low mileage 60,000 + it has cost me more money in repairs including the current recall for under body rust. I have gone through mufflers and other front end parts and my new mechanic even commented about the large amount of rust. I now have a grinding noise and it is probably wheel bearing hubs. A garaged car should not have these issues, this recall should extend to my exhaust which again needs replacing, and my grinding noise which I believe is related to the rust issue.”
