I own 2010 Qx56. On November 16th I was coming out of parking garage at chicago o'hare airport. After I pass the pay booth, with in 15 feet at the speed of 4 to 5 miles per hour, I lost control of the steering wheel because of some malfunction of the steering wheel assembly. Steering wheel moved 180 degree in one second and hit the pay-booth. Car hit the side pavements of the pay-booth and caused the flat tire, damage the body of the car and steering wheel got locked. All the power-steering fluid got leaked out. I had a fractured thumb because of the rapid movement of the steering wheel. Car was not drivable and ended up towing to the dealership. Dealer replaced the whole steering wheel assembly. This can be a major safety issue. I was just about to go on high-way. If this would have happened on expressway. . I am not sure I would be alive.
Intermittently in the past few months my Infiniti q56's brakes have been becoming soft and grinding when trying to stop. The brake light and the slip light also come on when this happens. When I stop the vehicle and turn off the motor, remove the key and then restart it will reset the brakes and they will go back to normal. In the past week this happens almost everytime I drive it. It is very scary when this happens and I am afraid that I will not be able to stop. I have had the brakes checked and everything is good. I took it to the dealer and told them what was going on and they said immediately that it was the brake booster. They must be seeing this problem on a regular basis because they didn't even have to look at the vehicle to tell me what it was. I looked online and saw that alot of people are talking about this same problem with their q56's and Nissan armadas. I feel that this is a major safety issue with this vehicle and the company should be recalling the vehicles and fixing them. This isn't a maintenance issue, its a component failure.
