My 2009 Infiniti qx56 has a serious issue with the rear suspension that started about a year after I got the car when it was at about 100,000 miles and has gotten worse, even though repair shops and dealer keep telling me it's 'fine'... When traveling down the highway at speeds over 50mph, if I hit or drive over any bump or pothole or dip or uneven pavement, the backend of the car feels like it is going to fishtail or swing out of control and has gotten worse. Now, at slow speeds when I hit any of the aforementioned typical road / pavement issues, the back end sounds like it is slamming down on itself. Also, the brakes now sometimes feel like the pedal is "loose" and goes nearly to the floor. If I pump the brake again, it goes back to normal. I have taken the vehicle in and been told the

I was driving on interstate 435 w. In kansas city kansas. It was about 4:15 am traveling at 70-72 MPH my visibility was ok but I thought that if I use my highbeam it would be better. As soon as I clicked high beam on my car instantly turned off. My headlights my interior lights and my radio powered off. As a panic reaction since I had zero visibility and it was dark outside my foot the brakes. As I remember my sibal had already tightened up before hitting the brakes but before I could realize it my car part powered back on by itself without me doing anything I look at my speedometer and I was going about 67-69. When my car powered on it seems as if it rezoned as if nothing had happened now I believe if I was in kansas city kansas rush-hour I would have caused a severe accident . Even t

My car ran out of gas on the freeway. The fuel gauge still read 1/4. I have noticed this several times, that I know I am near empty based on mileage but my gas gauge still reads 1/4. I found a recall on-line that states that this car is affected but when I contact Nissan na and my dealer, both say, based on my VIN, there is no recall. This is what I found online: recall id # 68281 - fuel system, other:storage:fuel gauge system recall date: mar 03, 2010 model affected: 2009 Infiniti qx56 summary: Nissan is recalling certain model year 2005-2009 titan, armada, and Infiniti qx56 vehicles.
