Engine and engine cooling
- What is wrong
- Nissan is recalling certain model year 2004-2006 armada, titan, infiniti qx56 and model year 2005-2006 frontier, pathfinder and xterra vehicles. The intelligent power distribution module (ipdm) assembly contains an engine control module (ECM) relay that has a diode for electrical current noise reduction. The ECM relay may allow silicon vapor to form and, over time, the silicon evaporates from the diode molding which causes silicon oxide to develop on the ECM relay contact due to arcing.
- Risk
- This could cause engine stalling increasing the risk of a crash.
- Remedy
- Dealers will replace the ECM relay inside the ipdm assembly. This service will be performed free of charge. The safety recall began on december 6, 2010. Owners may contact nissan at 1‑800‑647‑7261.

What 2006 Infiniti QX56 owners say
Most recent owner complaints, unedited.
Air bag not working, horn not working properly. And other functions. Was told clock spring needs to be replaced.
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.
My vehicle stalling all time which is very dangerous especially when I m driving on highway . More than 10 times I almost crash my vehicle.
2006 infiniti qx56, had back brakes and rotors replaced in october 2020, 2 weeks later I'm driving, flat surface, nice day, applied brakes, my pedal went to floor, no resistance, I heard a grinding noise, felt like a 'slip' , I had kids in car, I pulled over, asked the girls what they heard, turned off vehicle, checked brake fluid, full, the girls thought I may have hit a slick patch of oil or something?? We did our shopping, I made a few phone calls, got back in vehicle, started it and applied brakes, worked fine, drove home slow, no issues. Also no lights came on when this happened. I convinced myself this was just a fluke. 2 1/2 weeks later and after lots of driving, I had to go to memphis 5 hours away with my daughter. Everything fine until we got there. Checked into hospital, then decided to go downtown 4 blocks away. Started car, drove slow, at 3rd block went to brake as usual and it happened!!! Brake pedal went to floor, loud grinding, clunking, brakes wouldn't work, this time light came on. Just the red brake light. I got pulled over, shut off vehicle, checked fluid levels again, full! Scared now. I'm in memphis. When I started car back up it was fine. I don't want to drive home. Have read all the brake sensor probs, no recalls, deaths, unable to stop, I'm frightened and don't know what to do. Nissan will be hearing from me
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.
Difficulty stopping. Pinging noise. Replaced the brakes but didn't fix the issue. Very dangerous as it's very hard to brake and brake light comes on. Happened a couple times and it seems to reset once the car is shut off! Very scary. Happens out of the blue.
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.
Tl* the contact owns a 2006 infiniti qx56. The contact stated that while driving approximately 65 MPH, the vehicle started to vibrate and decelerated independently. The vehicle stalled without warning. The vehicle was towed to an independent mechanic to be diagnosed. The contact was informed that the radiator failed which caused coolant to mix with transmission fluid and caused the transmission to become inoperable. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was 200,000.
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.
