What 2007 Infiniti QX56 owners say
Most recent owner complaints, unedited.
My truck completely shuts off while driving long distances on the freeway at speeds greater than 60 MPH and then slowing down in stop and go traffic. It also falls dead on local roads at 30-40 MPH. I can literally press the gas pedal to the floor and with no pressure to the accelerator. There are no warning codes or alerts when this happens. I took my vehicle to the southwest infiniti paid for unnecessary service and the problem still remains. I am able to restart the vehicle;but from only park or neutral. I then have to rev up the engine for at least 5 mins before I am able to get any type of acceleration. This is very dangerous and I almost got hit several times.
When driving at slow speeds break light comes on, and the brakes vibrate. I've taken the car to the dealership and the technicians could not find the problem. I then shut off the engine and restarted the vehicle and the brakes worked properly. The same issue has happened twice, once at lax, and the most recent being today 6/11/2019.
While driving the SUV on the highway I went to brake and it acted as if the ABS bra king system engaged. The brake light came on the dash. I pulled off the highway and turned the car off. When I started the car again the brake light went out and the brakes acted as normal after that.
The brake light comes on, the brake pedal weakens and brake system makes a rattling noise when the pedal is pressed. It makes it very difficult to stop the car.
While driving and I go over a bump the car jumps to the side. Also lights on dash stay on for seatbelts, tire pressure.

The vehicle was taken back to glory auto sales where the contact stated that she needed to pay for a second replacement of the cluster. The vehicle was not repaired a second time due to cost. The manufacturer was not made aware of the failure. The failure mileage was unknown.
While driving brake light comes on (not ABS light), and when push the brakes is hard to stop and has a rattle noise on brakes, if you turn the vehicle off and turned back on everything goes to normal, I know that this problem is on nissan armada wich it has a recall but not on the infiniti, the recall is delta stroke sensor with code c1179
The power brakes seem to go out during driving. They chug then require extreme force pressure on pedal to stop. Shutting down the car and then waiting and turing it back on seems to restart it.
Takata recall my airbag light has been flashing accompanied by some clicking sound or noise that stops after some seconds.this happens each time I turn on the car
