A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
Consumer's vehicle was in a head on collision while driving at approximately 45 MPH. Upon impact, the air bags failed to deploy.
Tl* the contact owns a 2004 infiniti q-x56. The vehicle was having a routine oil change when the dealer informed him that the front brake pads were defective. The brake pads were replaced at that time. While driving home from the dealer at unknown speeds, the brakes did not feel normal and took the vehicle back to the dealer. The dealer advised that the brakes were normal and would feel uncomfortable until they were broken in.
While driving at approximately 45 MPH under clear driving conditions and towing a travel trailer, infiniti qx-56 had an extensive electrical fire in front, interior console, which caused major/extensive damage to vehicle. If not extinguished with a fire extinguisher, it would have caused major injury or death to the occupants and totaled the vehicle. Infiniti replaced all of the defective components (approx $12,000 of damage to the vehicle).
Vehicles airbag light flashes continuously as if it went off. It is unknown if the airbag will function during a crash. A quick internet search will return numerous sites with thousands of users with similar issues. People have come up with a reset procedure for this warning light, but it seems to reoccur for everyone involved. Airbags may not function during head on crash.
Stepped on brakes and pedal went all the way to floorboard with out stopping the SUV. SUV finally stopped on speed bump a few feet away. Looked in the internet, there are other people with same problem. There is also a couple suing nissan for this very problem. I think nissan should be held responsible. The problem I understand is in the brake power booster. It should have being recall.
