What 2007 Infiniti QX56 owners say
Brakes
I'm having brake problems with my 2007 QX56. I have been experiencing a brake problem twice in 2 weeks. At random times, it is difficult to bring the vehicle to a stop. It acted like the ABS was trying to engage. It was like I was slipping on something when I was applying the brakes. There is a slight metal rattle noise while pressing the brake pedal all the way down while trying to come to a stop. The brake light comes on. There is no shaking of the steering wheel or vehicle. No fluid leaked or anything I could see. The brake fluid but it was not real low above the min mark but below the max mark. After the brake problem occurs, a restart of the vehicle will make the brake light go away and the truck drives fine. I have been google their were a lot of complaint about Nissan armada, Nissan titan and Infiniti QX56 vehicles have dangerous brake problems same as my issued. …
While driving my vehicle I applied the brakes to slow for a turn. My brakes make a loud grinding sound and were not properly working. The brake light came on and pulled off the road. Once the vehicle was put in park and restarted the light went off and the brakes worked properly again. I have read several other stories of this happening to others. Why isn't Infiniti doing anything about this? This has happened a few times since I have owned this vehicle.
Suspension
While traveling at normal highway speeds any road imperfections, pot holes, bridges, or bumps will cause the vehicle to veer to the right and feel as though you are loosing control. Two hands must be used while encountering anything other than a perfect road. It is extremely scary and unsafe when traveling at speeds greater that 50 MPH. It feels as though the rear of the vehicle is getting ready to pass the front. This is our family vehicle and I fear for my families safety while driving. The suspension has been checked and has been found to be in working order although it is obvious something is extremely wrong.
Had new tires put on my Infiniti QX56....after doing so sounds as if rear end is slipping. I have 3 children and am afraid that this could result in an accident. Horn quit working 1 year after I purchased vehicle. This I know is dangerous because there is no horn to blow, in cases where needed. Fan on blower quit working, only works on high. Passenger seat will no longer adjust. Fan and passenger seat quit working approximately at the same time. No one wants to have an accident, but when you hear things like the rear end and front wheels sound as if they might fall off....that is scary.
Electrical system
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.
There is an electrical malfunction that has caused my horn to work only when the steering wheel is sideways and it also affects my ability to control my drivers seat positioning. This is very dangerous a car cut me off on the freeway at very close distance. I would have never known that there was an issue if this did not happen.
