Service Brakes Problems of Infiniti QX56 - part 1

There are times when driving under 50 mph brake light comes on and the brakes have goes out which cause me to do an emergency pullover turn off the truck for a few minutes and the brakes reset. This is very concerning for me. This has happened on a few occasions.

My wife was driving home from work, said brake is failing, makes loud grindy, rattling noise when brake is applied. Once the car is turn off and back on, everything is back to normal. When I got home, I took the wheels off to check everything was ok, pads were almost new, which I replaced last year. Drove around for 10 miles no problem. This is a serious safety issue which Nissan/Infiniti should take care of.

Brake failure. The brake fails occasionally while driving on the streets or on the highways without waring. The brake pedal goes down to the floor, and grinding/hitting metal to metal sound is heard and vehicle brake control is lost. Experiences were traumatic; you swing left or right to avoid hitting another vehicle from behind or running a red light. The vehicle has been inspected by an independent mechanic, and the brake components: rotors, pads, drum, and fluid levels were ok, each time it occurs. The brake lights come off and on and each time, the mechanic finds no issues with the brake components. One dangerous aspect of these occurrences is that after the vehicle sits for a while, like 30 minutes to one hour, and you go back to driving the vehicle, it appears that the brakes readjust and starts working normally; it continues to work normally about a month, and out of nowhere without warning it fails again and readjusts later. I was about to take my daughter to college out of county, and she has a lot of luggage as she lives in the dormitory; we would not use this infinity which is a large SUV that could have accommodated me, my daughter and my wife, because of fear of brake failure on the highway. We decided that we would have to use our small compact Lexus instead, but I would not be accommodated in the Lexus because of my daughter's much luggage; my wife and my daughter will make the trip without me. Please look into these break failures.

The brake pedal seems spongy and while braking at slower speeds the seat belt pulls back violently pinning the driver back against the seat. Rear brakes have been replaced and brake system fluid check still no different.

I was on the highway driving my family from texas to north carolina when I ran into rush hour traffic long the way. I applied the brake to slow the vehicle down, then suddenly the steering wheel started shaking, there was a lound gridding noise as if the engine about to fallout and my brake didnot hold immediately when applied.

I was driving at approximately 60 mph on a freeway when traffic ahead came to a sudden stop. I pressed the brake pedal and it traveled to the floor and I did not feel the car slow at all. The "brake" dash indicator light came on, and I continued pumping the brake pedal to try and slow the car. While I continued pressing the brakes, the car started slowing down rapidly on its own as if it was pressing the brakes on its own and I could hear a loud grinding sound. I released the brake pedal and crossed several lanes of traffic as the car was uncontrollably slowing to reach the shoulder. I called my husband to tell him what had happened and remained on the shoulder with the car running. My husband met me on the shoulder and drove the car home. He said that the grinding sound was the abs on in a permanent state, and would activate during every braking unless the brakes were applied extremely lightly. The car was driven to our driveway and turned off. Several hours later my husband drove it again. The "brake" light was off, braking returned to normal, and abs could be activated with hard braking as usual.

The vehicle will lose power to the brakes while driving intermittently. When problem occurs you will lose power steering and pressure to braking system. Also the driver hid headlamp gets moisture in it whenever it rains. I have had to replace the hid bulb about 6 times in the past year. Also there seems to be an electrical issue with the onboard computer that causes the tachometer to not work or read correctly.

I hear I ping sound like a spring, the break light comes on and I am unable to stop the vehicle as normal. Appears the vehicle is attempting to slow down but does not come to stop as it normally should. Once I turn the vehicle off then back on it's just fine until it randomly occurs again when applying the breaks and/or when the vehicle is idle and the break light comes on. This issue only resolved itself when the vehicle is turned off then back on. It is extremely alarming and could cause an accident.

Driving down highway 421 in wilkesboro, nc on a 45 mph section of the highway, merged over into the turning lane to turn left across two lanes of traffic. Waited for a break in traffic, upon a break in traffic tried to accelerate to cross traffic, as vehicle started to accelerate it stalled in middle of road. Wife and children in car started screaming. Traffic nice enough not to run into us. Had car towed to local automotive repair shop. Found that this is a common problem for the 5. 6 litter Nissan/ Infiniti engine. One of the timing gears for the left bank stopped rotating some how. This side of the engine timing system also powers the fuel pump so that you cannot even limp across the road on half the engine. It just stops right where you are. You have no steering no breaking and no propulsion. This is a dangerous situation and the manufacture should be held responsible for the design and lack of quality of the engine.

Occasionally brake light turns on in my dashboard then my braking system loses hydraulic pressure and I have troubling braking till I turn car off then resets and goes back to normal but while brake light us on is very troubling and concerning? this has happened on many occasions since purchasing the car if I remember in 2018.

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.

Tl the contact owns a 2008 infinti Qx56. While driving various speeds, the abs warning indicator illuminated and the vehicle decelerated and stalled. When the vehicle was restarted, the vehicle was able to operate. The vehicle was taken to priority Infiniti of greenbrier (1812 greenbrier pkwy, chesapeake, va 23320) to be diagnosed, but the cause of the failure could not be determined. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 132,000. The VIN was not provided.

On two separate occasions while the car was moving in a dry parking lot and applying my brakes, my abs brakes kicked on for no reason and the car was difficult to control and stop. The light came on as well and I heard alot of grinding. This was very scary as both times I had my children in the car. The only way to reset abs was to turn off vehicle. I am so afraid that this will happen again and I may not be able to stop. I am now afraid to drive and am thinking about selling it because I feel it is not safe to drive.

While in motion attempted to stop at intersection red light. Vehicle failed to stop. Lights on dash blink, power locks open and close along with windows by self while in motion and stationary. Several occasions vehicle would not start. Dealer states "no issues found".

My brakes sometimes just goes crazy!!! the petal goes to the floor and it grinds and it is completely out of control. It only gives me one date below but it has happened multiple times.

Multiple times the brakes have went out and I have been unable to stop the vehicle. This has happened in various places and during various circumstances including on the highway and city streets, it has also happened in parking lots. There is no indication, warning lights or signs when they stop working,I find out when I press on the back and it makes a odd sound almost like a spring and a pulsating/grinding feeling when I press the break down. No indicator lights come on when the brakes go out. I am unable to get the vehicle stopped during this time. There has been no set reason or pattern for the breaks going out, they just randomly stop functioning. Normally when this happens for the past year, after I get my vehicle to a complete stop, I turn the vehicle off and then back on and it's back to normal. However the most recent incident was on 2/24/2018 and the brakes went out 4 separate times even with turning the vehicle off. I feared for the safety of my children in the car and myself so the vehicle was returned to my house and not drove again until 2 days later. Infiniti was notified of the problem as well. I am greatly concerned this will end up causing a vehicle accident and injury to my children, myself or anyone else. When this first started happening I had brakes and rotors changed but problem continued. There is no rhyme or reason for when they go out and I have no control over stopping my Qx56. This is very concerning to know it can happen at anytime!.

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).

Passenger air bag light and dash light is on all the time.

When applying the brakes a grinding sound occurs. The abs warning comes on and you really don't have control of the vehicle. It is really scary. It has happened a few times but yesterday was a very close call.

The contact owns a 2006 Infiniti Qx56. While driving 30 mph, the vehicle made an abnormal noise after depressing the brake pedal. The pedal traveled to the floorboard and the vehicle would not stop. The contact was able to regain control of the vehicle after taking her foot off the brake pedal and steering into an empty parking lot. The brake warning indicators illuminated. The vehicle was taken to the dealer where it could not be diagnosed. The vehicle was not repaired and the failure recurred. The manufacturer was not notified of the failure. The VIN was unknown. The failure mileage was approximately 140,000.

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.

When I'm stopped at a light the vehicle will start to roll forward unexpectedly and extra pressure needs to be applied to the brake pedal to prevent the vehicle from moving, at this point the brake pedal is almost at the floor and pumping the pedal a few times will restore the brakes to a normal feel. The Infiniti dealer states this is a normal condition and repairs are not needed. This has been ongoing since 04/2015 to present.

My 2009 Infiniti Qx56 has a serious issue with the rear suspension that started about a year after I got the car when it was at about 100,000 miles and has gotten worse, even though repair shops and dealer keep telling me it's 'fine'. . . When traveling down the highway at speeds over 50mph, if I hit or drive over any bump or pothole or dip or uneven pavement, the backend of the car feels like it is going to fishtail or swing out of control and has gotten worse. Now, at slow speeds when I hit any of the aforementioned typical road / pavement issues, the back end sounds like it is slamming down on itself. Also, the brakes now sometimes feel like the pedal is "loose" and goes nearly to the floor. If I pump the brake again, it goes back to normal. I have taken the vehicle in and been told the "brakes are just fine" and they act like they don't know what I am talking about. The same with the suspension, except for now there is a "tinging" sound sometimes upon starting or accelerating. The repair shop told me the struts and shocks etc 'are fine', but that there may be an issue with the suspension the dealer acted like they didn't know what I was talking about, but after research here . . . I see that this exact problem is common with this vehicle and the 2011, such that there is a recall for the models manufactured Nov. 2009 and 2010. All of these vehicles should be fixed by manufacturer. They know this is an issue and even recalled some vehicles. This truly could kill us some day. . . Brakes don't work or the car's back-end swings out of the lane and fishtails out of control on the interstate. It happens all the time now. I researched because I need to drive my son to college and knew it didn't feel safe. I found you may already be investigating these issues and I would like a resolution and to have my testimony included. It's dangerous.

While driving the vehicle and pressing on the breaks there is a cranking,grinding noise and the breaks appears to lock up the slip. Vdc off light illuminate on the dashboard,breaks not working properly.

When applying the brakes, the brake pedal was soft and the front tires had grinding and chattering noises like a abs brake system malfunction. The care would not stop very well. The vehicle was going slow on dry pavement so there was not reason for abs to activate. Continued to have this problem each of the dozen times I applied the brakes until I pulled into a costco parking lot. One of their mechanics drove the car and noticed the problem, but when we inspected it, it had nothing to do with the tire balancing that was just performed on the vehicle. I shut the vehicle off and turned it back on and the brakes worked normally. This has happened while my wife has driven the vehicle about 10 times in the last 4 years, but this was the first time it's happened with me when driving. Very dangerous. The description sited in the class action lawsuit fully describes my experience. . Read more...

I applied brakes with plenty of lead time but the Qx56 failed to brake causing me to rear end another SUV; I did minimal damage to the other car but damaged my radiator/front-bumper/hood. I had a similar abs issue about a week before as described by many for the 2004-2006 Nissan/infinity recall but I didn't research that recall until this current accident. My airbags did not go off. On initially breaking it sounded like the abs was going to kick in but the car kept moving forward with none of the normal pulsing action that would normally be felt with abs and no reduction in speed as the brake pedal was fully depressed.

The brakes get hard and cannot stop quickly. It grinds and have to park and cut the engine off for a few minutes then it works again. Almost caused a fatal accident. This is definately a factory defect due to lots of owners on the net having the exact same problem. There is no indication when it about to happen. It happened at least three times since buying this vehicle used for my wife. This problem happens also with the Nissan armada. Contacted the manufacturer and they don't seem concerned at all. They says to bring it to your local dealer on my own expense. This is an design problem due to the amount of complaimts from customers. I am concerned about not only my family safety but others. Thanks.

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.

During the first two occurrences, while attempting to engage the break pedal to slow down, the brakes appeared to "open up" causing the vehicle to thrust forward in a sliding motion instead of coming to a halt. While repeatedly pumping the brake pedal, the braking system appeared extremely "loose" and the brakes would appear to engage and quickly disengage. The span of breaking for each occurrence lasted about 200-300 feet before the vehicle would eventually come to a complete stop. Following both occurrences, the vehicle was turned off and the brakes appeared to work properly after restarting the vehicle. During the third occurrence, the exact incidence described above occurred when trying to bring the vehicle to a complete stop; however, the span of breaking lasted about 400 feet. While constantly pumping the brake pedal to gain control of the vehicle, the brakes went from being extremely "loose" and going to the floor to becoming extremely hard and not engaging at all. The brake pedal appeared to have locked and no pressure could be applied to the pedal. Once the pedal locked, the vehicle came to a gradually slow stall and eventually stopped without the ability of applying the brakes. As with the previous two occurrences, the braking system would appear to operate properly after restarting the vehicle.

Brake does not brake when squeezed scares me the mechanical and did not find the problem I have children.

The contact owns a 2006 Infiniti Qx56. The contact stated that while depressing the brake pedal, he noticed an abnormal grinding sound. The manufacturer was not made aware of the failure. The vehicle was not inspected or repaired. The approximate failure mileage was 171,874.

Stepped on brakes and petal 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 sueing Nissan for this very problem. I think Nissan should be held reponsible. The problem I understand is in the brake power booster. It should have being recall.

Since I purchased my Qx56 2006, it has happen several times, I think approximately 10times, I got scared at the beginning and freaked out, all my family was with me and we didn't know what to do, all I did was turn the car off and wait for a minute then I did turn the car on and the problem was gone, I'm not the only person that has this happen and hope that you guys do something about it the only big problem I think is that I'm afraid that if this happen again and I will not be able to stop my car and will cause death by hitting somebody, I had a small incident but there was no big damage and the car in front of me heard the noise but we didn't fill a report if you have any questions, you have my VIN # and you can find me I hope that Nissan does something about this.

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.
