general problems of the 2006 Infiniti QX56

SUV will have trouble braking, emitting a loud, grinding noise when brakes are applied. Diffiulty stopping. Almost caused a wreck twice now. Once vehicle is turned off and back on, the situation seems to stop. Happens periodically. First time had brakes, rotors redone in case there was an issue, though there did not seem to be according to the mechanic. Has continued to do it a few additional time. Took it into Infiniti dealer. Was told it was the brake vacuum booster. This item has been recalled on other 2004-2008 Infiniti qx-56 and Nissan armadas. Was told that my car was not on the 'recall' list.

When my car is in motion and I go over any bumps it pulls the back end of car my to the side and bounces around so much that I almost don't have control of my car. This will pull so much it take me to the side of the land im currently in I have to make sure I look out for bumps in the road and make sure I slow down below the speed limit so I can keep control of the car. This causes my abs to turn on when going over bumps because the car think im not in control which also cause more issues. This also cause a risk as I have other traffic driving around me, I have children and I am in constant worry that im not going to be able to slow down to keep control especially on a hwy there is no slowing down to 20mph on a hwy. 2nd issue my dashboard light continuous flicker and then go out. Rpm/tack needle has quit working. I have had this repaired several time and still have the same issue.

I own an Infiniti qx 56 2006. I started the vehicle from my driveway I noticed the the gauge cluster showing the rmp side was not moving and the coolant level was fading. So far my speed is still moving but I'm scared it will stop working!!!.

When I am driving (pressing the gas) an inconsistent random clicking noise that's affecting the brake system and usage is heard. It's difficult to accelerate. In the past, I would simply turn off the vehicle and turn it back on and the noise would stop. It was difficult to explain and show to any mechanic because it does it randomly and unexpectedly, therefore it would never do it when needed. I went on because it wasn't often at first. Now it's at an extreme level as if the vehicle doesn't want to drive and I could be on the highway (you can imagine how scary that is at high speeds).

The car emergency brake light came on, the vdc, and slip light flashes and the car loses brake power, felt like pads were gone but they were not. Once the car was turned off and back on lights went away and brakes came back. We have had brakes replaced, and problem continued. Also the service engine soon light came on and a mechanic told us we needed new cadalidic convertors and the service engine soon light is still on and off. Brake issue and light coming on has happened numerous times and it does not make a difference where or what speed. I have been driving down the interstate, in the neighborhood, parked, etc. It is happening more frequently and we have had it check out by multiple mechanics and their diagnostics are not picking up anything that is wrong. I have 3 small children and feel like I am going to have a panic attack every time we get into the car. Why is there no re-call yet?! if you are considering buying this car run and do not buy!.

Vehicle stalling and losing power and all warning lights on dashboard begin to flash. On several occasions vehicle completely stalled while I was driving on the freeway causing me to lose power steering control and almost causing an accident. Problem comes and goes without any pre-warning.
