The vehicle died when at a stop light and rolled back hitting the car behind us. I looked on your website and apparently it was caused by a faulty engine control module (ecm) in the intelligent power distribution module (ipdm). This appears to have been recalled on all 2004 to 2006 Infiniti Qx56 vehicles, however, I received no such notice and Infiniti says their is not recall associated with my VIN number. I believe my VIN number was left out in error and this should be recalled. This vehicle has also lost power a number of times while driving, but those incidents didn't result in an accident (luckily). Thank you.

I was driving down the road when my brakes started to skip. I stop my vehicle and put the vehicle in park and then put it back in drive then I was able to drive again as normal. It happen three more times after that. It's very dangerous for this kind of issue to occur in travel while driving at any rate of speed. I need this issue looked at by the dealer ship at their expense.

The contact owns a 2013 Infiniti Qx56. The contact stated while driving approximately 10 mph, the vehicle lost acceleration power. The contact also stated that the failure occurred intermittently. The vehicle was taken to the dealer for diagnostic testing. The technician was unable to diagnose the failure. The vehicle was not repaired. The approximate failure mileage was 2,000. Mah.

The standard Qx56 comes with more than adequate room for any size shoe on the accelerator pedal. Less than 10% of the qx models are ordered with the technology package. This package includes a design feature that causes the gas pedal to push back against the operators foot if the radar senses that the vehicle is closing distance too quickly on the vehicle ahead. The mechanical/electrical device that performs this action is mounted to the firewall at the top of the accelerator pedal. I am 6'3" tall and have a size 12 shoe. The tip of my shoe keeps getting caught under this mechanical device and on multiple occasions in the first week of ownership it has caused a momentary delay in quickly moving from the accelerator to the brake pedal. The hang up of the tip of my shoe is exaggerated greatly by dress shoes with a firmer tip of the sole of the shoe. Again, this device is only present on qx models with the technology package. This tech package device also gets in the way as you go to push on the gas pedal. The only way to avoid this problem is to always remember to place your right heel at least 2" away from the base of the gas pedal and push it only with your toes. Moving your heel away from the bottom of the pedal results in the tip of your shoe touching the pedal lower and just brushing the underside of the tech package device. I have contacted consumer support at Infiniti USA and they have told me that they have had complaints but "that's just the way it is for people with bigger feet". I guess they don't have size 12 in japan. This is a hazard when the tip of my right shoe gets caught and prevents me from moving quickly to the brake.
