While driving the emergercny brake dash light will become lit and all braking actions have drastically reduced power. A an audible grinding noise is observed from the front of the vehicle and the brake peddle has little to no resistance. A restart of the vehicle temporarily resolve the issue, but the issue has reoccured numerous times and is increasing in frequency.
2004 Infiniti QX56 brakes complaints
Page 2 of 3: complaints 11 to 40 of 65, newest first, as owners wrote them.
Passenger air bag light and dash light is on all the time.
Emergency brake: e-brake appears to engage on its own and the brake light indicator comes on. There's also a grinding sound when brake is pressed. Grinding sounds only occurs when this issue comes up. Exhaust manifolds: was notified by the dealer upon a service inspection that there was a small crack in the exhaust manifolds. Is this a normal thing? And should this be a recall item as it could throw off any smog check testing. In addition how about the exhaust in the cabin issue? Maybe they used too thin of a metal for the manifolds.
Brake light came on and braking was affected while driving on a town street going about 25 MPH. Once car was turned off and cranked light went off and brakes were fine. Have seen other complaints about a faulty sensor.
Brake does not brake when squeezed scares me the mechanical and did not find the problem I have children
When driving vehicle suddenly makes a loud grinding sound and ABS and brake light come on on gauge. When trying to break it is impossible. It will not stop. This has happened more than 6 times already. Thankfully I was not in traffic or collision and injury could have happened. In order to regain control you have to turn vehicle off to reset it. This problem may cause a severe injury or even death.
I have an 04 qx56 as a daily driver. I was leaving walmart as I pulled out of the parking lot I pulled into the turn lane to allow a car to go by mashed my brake and it started jer king like something was trapped in my brakes. We pulled on down to a large parking lot got out notice the red brake light was on and under the hood something was clicking near the air intake thing. It did it the entire ride home as we were 30 mins from home we just drive slow. Got in it today for the 1st time was ok til about 45 mins into trip light came back on brakes started doing the same thing. I have read many people complain of this issue. If it doesn't get recalled there will be a wreck in these vehicles! Please make nissan/infiniti recalled this part! I have researched it and there was a lawsuit filed but it didn't make them admit there was an issue just made them pay for out of pocket expenses. I am a stay at home mom college student my husband just lost his job due to health reasons. I can't afford to pay for this issue!
While driving the vehicle and pressing on the brakes there is a cranking,grinding noise and the brakes appears to lock up the slip. Vdc off light illuminate on the dashboard, brakes not working properly.
I have a 2004 qx56 -- I'm having the same issue with my brakes. All of a sudden the brake light will come on and when you press on the brake you hear a scary loud grinding sound and trying to stop it really tough. It feels like the ABS brakes kicked in --- it has happened several times randomly. As soon as I turned the truck off and restarted it the brake light came off and it started to drive like normal. But I have hit the grass several times bc when this failure occurs you're likely to hit someone in front or, with a sudden grinding stop, someone hit you from behind. I took it to the shop and they said it was a brake issue. So I replaced all 4 brakes and rotors -- yet the problem still happened!! I went back and they said it's probably the delta sensor and it'll be $1000 plus a few hundred to update the computer too. This is very dangerous and the scary part is there is no warning-- it just happens randomly. This is something infiniti / nissan should fix!!
I have a 2004 qx56 and like many of you, I ma having the same issue with my brakes. The brake light will come on and when I press the brake their is a grinding sound and it is very difficult to stop. I turned the truck off and restarted it and the light went out and you couldn't tell that anything was wrong. I took it to the dealer and was told it was my rotors and they "think" the brake booster. This is a very serious problem and nissan needs to be held accountable and made to fix this issue.!
Tl* the contact owns a 2004 infiniti qx56. While engaging the brakes, the ABS light illuminated and an unknown noise emitted from under the vehicle. The contact mentioned that the brakes failed to stop the vehicle. The vehicle was taken to the dealer. The technician was unable to find a failure. The brakes and rotors were replaced, but the failure persisted. The manufacturer was made aware of the failure. The failure mileage was 42,000. The VIN was unavailable.
While I'm driving, the brake light on my cluster would come on and if I try to brake, the pedal would just go to the floor and the vehicle would feel as if ABS is kicking in. This is very dangerous as I've ran through multiple red lights and pedestrian crosswalks due to the brakes not working properly. Thank god I haven't hurt anyone or myself due to this on going problem with the delta sensor. Researched online and read tons of stories of people with the same issue which apparently cost $1000 usd to fix!! Please make infiniti responsible for this fix or someone will get hurt or even worse, deaths.
While driving and starting to apply the brakes there can be heard a grinding sound, brake light displays on the dash and the brake pedal goes to the floor.this is very unsafe to me and the public because once I was able to get home and restart the vehicle it functions like nothing was ever wrong. I drove around the block with no problem stopping which lasted about 2 weeks before it all started again, this time with my family in the vehicle.there are no leaks or squeaking from using my brakes; something needs to be done.
Stepped on brakes and pedal went all the way to floorboard with out stopping the SUV. Suv finally stopped on speed bump a few feet away. Looked in the internet, there are other people with same problem. There is also a couple suing nissan for this very problem. I think nissan should be held responsible. The problem I understand is in the brake power booster. It should have being recall.
While traveling on the highway to another state, I attempted to stop my vehicle, an 2004 infiniti qx56, as traffic slowed and stopped. I pressed the brake pedal and heard a clicking sound and the brake indicator light came on and the vehicle would not stop completely. The pedal began to go to the floor then began to feel stiff. I had to swerve to the side of the road to avoid hitting someone else's vehicle. Once I completely stopped, I got out and inspected the brake fluid level, and the brakes and both seemed to be fine. I got back in the vehicle and after I turned the ignition on, the brake indicator had went off and the pedal seemed to be working fine. I traveled on to my destination without any other issues. Once at my destination, I had the brakes inspected and the repair shop said they could not find an issue. This has happened several more times since this incident, and each time when taken to a repair shop, nothing can be found wrong with my brakes.
Car was being driven at approximately 40 MPH when the brakes vibrated significantly and failed to engage at an intersection nearly causing an accident. An infiniti dealer indicated that the brake booster had malfunctioned.
Coming up to a stop light I press on the brake and it goes to the floor and the ABS kicks in for no reason. I almost went through the red light. All of the brake, slip, vdc lights came on suddenly. I turned the truck off and back on again and everything is fine.
The brake light came on and a loud clanking noise was heard when you pressed the brakes. Once you stopped cut SUV off and cranked it back up it was fine.
While driving the vehicle and pressing on the brakes there is a loud cranking, grinding noise and the brakes appear to lock up. The slip, vdc off and brake lights illuminate on the dashboard. I will usually have to turn the vehicle off and back on for the lights to go off and to drive the vehicle. This works intermittently.
I have a 2004 qx56 and have been having brake problems since I first got it. The brakes were replaced under an initial recall in 2005, but a new problem began in 2006 and has been occurring since. Initially, only about once every 2 months, the brakes will sporadically pulsate and the car will come to a quick halt. I would just restart the car and it was fine. The dealership said it was a firmware problem, and "flashed" the firmware. It still kept happening, they flashed the firmware over and over again, and then just said there was nothing more that could be done. Now that the truck is out of warranty, the dealership says it is being caused by a bad brake booster, and will cost $1,100 to fix. But this has been happening since long before it was out of warranty, and now it is happening much more often, almost every day. Review of different infiniti forums shows many qx56's, nissan armadas, and nissan titans are experiencing this problem. Nissan has put out a service bulletin acknowledging the problem, but their solution does not solve the problem. This should really be investigated further and a recall issued for whatever the cause of the problem is.
Brake light and slip light turns on in instrument panel, brakes do not grab or makes a grinding sound. My rotors and pads are in good condition per dealership.
Same issue as all other posting..loss of brakes, shudder, lights go off. I had it towed in. As it was under warranty, they reprogrammed and redid all brakes...now, same problem 9 months ago..I cleared everything and it recurred again..this is lifethreatening...I'm amazed no action has been taken with all these posts (and many others on other compliant boards). Will someone have to get killed and then officially start a class-action?
Complete brake system failure - this is the 3rd time, same exact symptoms. Brake light on dash comes on, computer noises beeping behind dash, brake pedal looses all pressure, vehicle unsafe, crash was imminent, if we had been traveling at highway speeds there would have been death. Brake pedal pushed all the way to the floor front brakes began making severe grinding noises, vehicle virtually incapable of stopping. This is a severe problem. Previous failure on 3.30.11 at 68kmiles, 1st failure on 8.20.10 at 57k miles. At 70k miles dealer reprogrammed vdc control as 'fix'........guess what it did not fix it........this needs to be a factory recall item asap, and/or a class action lawsuit before someone is killed>
Driving with my two young children about 35 MPH when I depressed the brakes the car shuttered badly on the front end and the peddle went all the way to the floor and the vehicle barely slowed down. Luckily there was no-one in front of me or I would have crashed. Problem continued until the vehicle was turned off and re-started. Extremely dangerous!!! Many other similar accounts and it doesn't sound like there is a difinitive resolution to the problem even after spending thousands at the dealerships.
Yesterday april 10,2012 I was driving and need to stop the my qx56 I feel a complete brake failure,brake warning light on and a loud noise under the vehicle. Brake pedal doing all the down to the floor. After turning the vehicle off and restart, everything turn back to the normal and warning light gone. This is serious issue and manufacturer should fix the problem before any body die.
Today, while my wife was driving our 2004 infiniti qx56 with 106,134 miles, she experienced a complete brake failure, along with the "brake" dashboard warning light. It was described to me as the steering wheel and brake pedal shaking, a loud noise from under the vehicle, and the brake pedal going all the way to the floor. This exact same issue is all over the infiniti qx56 / nissan armada forum, the internet, and www.mycarstats.com site to which I'm a subscriber. It's ridiculous that with the number of stated occurrences of this failure on these vehicles that a formal recall has not been mandated to correct this problem. As with most of the other reports of this happening, turning off and restarting the vehicle eliminated the "brake" warning light and the normal pedal feel returned to our vehicle. There is at least one report of this failure resulting in a severe, almost fatal, accident and I'm sure if actually investigated that there are probably more. Nissan - infiniti - the federal safety agency: do something formal about this immediately before someone, their wife, and or children are hurt or killed!
Tl* the contact owns a 2004 infiniti qx56. The contact was driving 30 MPH when the brakes were depressed and a grinding noise emitted as the vehicle failed to stop properly. The emergency brake light illuminated during the failure. The vehicle was taken to the dealer and the manufacturer was notified of the failure. The vehicle was not repaired and the VIN was unknown. The failure mileage was 105,000 and the current mileage was 135,000.
This 95% total break failure has happened 2 separate times 8/2010 and 3/2011; and while no accident, there could easily have been one had I been traveling at a higher rate of speed, or if there had been other vehicles around me. Applied break, immediately brake pedal sunk to the floor, break light on dash came on, front breaks began making harsh grinding sounds (as when slip control enacts); had there been cars in front of me I would not have been able to stop w/out hitting them. Even with foot to floor vehicle did not stop, down shifted into 1st gear, and finally vehicle slowed and was able to stop. Pulled over and turned off car; after turning car back on brake light on dash had gone away and brakes were acting normal. This is a major safety hazard and someone may die from this. The front discs on this vehicle are no good even after infiniti/nissan has done their so called repair and continue to prematurely warp.a class action law suit needs to be formed to deal resolve this matter indefinitely. Dealer subsequently reprogramed vdc control.
While driving qx56 at approx 40 MPH brake light on dash came on. At intersection to turn left brakes would not function and slowing down was difficult. There was a loud clunk and "boing" sound when brakes were applied. Turned to avoid traffic and started up hill allowing speed to decrease. Motor was turned off. When restarted to examine failure light was no longer on and brake seemed to work fine. Contacted local infinity dealer, was told it was brake booster and would most likely need replaced. Was told there was no service bulletin or recall but they have seen the issue quite a few times.
Periodically, on the order of once every month or two months, the antilock brakes become erratic. The pedal goes soft and the brakes engage extremely violently. When it happened the first time I pulled over to the side of the road and called my infiniti dealer. I kept the engine running while I explained what happened and was told to turn off the engine, wait about ten seconds and then restart the SUV. The brakes worked normally after that. I was told the "computer had to be re-booted". This continues to happen on and off about every month or two. Never was given a satisfactory explanation as to why this occurs. When it happens if there is no traffic around, I put the car into neutral, turn off the key, then restart the car and the problem resolves. If I am in traffic I slow down gingerly, then pull off to the side of the road and turn off the key and restart the engine. This resolves the problem until the next time.
