- 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.

The contact owns a 2005 Infiniti QX56. The contact stated that while driving approximately 75 MPH, the vehicle lost motive power and stalled. The vehicle was later towed to the residence where it was discovered that no fuel was present although the fuel gauge indicated that there was a quarter tank of fuel in the tank. After adding fuel, the vehicle was restarted, and the vehicle operated as designed. The cause of the failure was not yet determined. The manufacturer was notified of the failure and the contact was informed that the vehicle was not included in the federal safety agency Campaign Number 10V074000 (Fuel System, Other). The contact indicated that the vehicle had experienced the same failure listed in the recall. The local dealer was not contacted. The failure mileage was 150,000.
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.
Driving 30 MPH in manhattan new york came to a red light pressed brake pedal felt no brakes pumped brakes felt like there was little to no braking ABS light came on so did brake light ran through the red thank god no cars where I front of me ,eventually stopped pulled aside then turned vehicle off and then on the brakes worked fine took it to straight to mechanic because I didn't feel safe driving the truck . He said everything looked fine your brake pads rotors fluid levels and tires are in good condition he connects his scan tool and said he didn't find any codes .I told him to keep the car drive it until he could figure out the problem 1 week after he calls me and said he was driving about 25 MPH in brooklyn new york and the brake light ABS light came on then he had no brakes told me 'it felt as if he was driving on ice 'he then scanned the car when he got back to the shop and said it had a code dtc c1179 advised me to take it to infiniti to get it diagnosed because it's a serious and potentially deadly problem. Called infiniti north america hotline and was told there were no recalls for this serious problems they told me take it to the dealership to have them service the car so now I have to drive a car with brake maybe working or maybe not working to have the dealership potentially overcharge me to fix a manufacturers defect that they know about I'm happy that I was in brooklyn driving only 25 -30 per without my children in the car.I live in jersey and normally on the highway driving (50-65 depending on posted speed limits if this brake problem happened omg . I read up on the code and found numerous vehicles compliants about this dangerous brake problem. C1179 delta stroke sensor nissan titan. Nissan armada and infiniti qx56 2004 - aprox 2010 they need to issue a recall to make these vehicles safe to drive
While driving in residential/business area my vehicle completely lost power and turned off. I drifted to the side of the road without power steering. Tried to start vehicle again. Vehicle would start but would immediately die-would not idle. After resting approx 5 minutes I was able to start again and continue home. This has happened 3 times in the past 2 months. I am terrified to drive this vehicle again. I also cannot keep the drivers side headlight working. Bulbs constantly blow out at over 300.00 dollars each.
Every once in a while, seemingly after slow driving where there are many stop signs not too far apart, the brake light comes on, the brake pedal weakens and brake system makes a rattling noise when the pedal is pressed. Then I turn off the vehicle and restart it and all is back to normal until the next time, can be days or sometimes weeks.
When driving, the brake light comes on for no reason and causes the brakes to work inappropriately. It becomes very hard to brake. The brakes seem to fall through and there is a grinding sound from the brakes. If I turn the vehicle off, and then back on it works fine. Then it happens again sparatically.
While driving straight on interstate I-95 during rush hour at approximately 30 miles/hour, I pressed on the brakes and the pedal dropped down and started making a weird noise (like grinding sound) and the car wouldn't stop. The ABS light turned on, check engine light turned on, the pedal lost pressure and the brakes locked up. I ended up in a crash, rear-ending the vehicle in front of me. The car has now been repaired from damages from crash but mechanic found no problem with brake system. Abs sensors, calipers, disks and pads where changed as precaution but problem reappears from time to time and seems to reset when vehicle is turned off and on again (brake petal raised back up, grinding sound disappears and the check engine light and ABS light shut off). I visited two infinity dealers and both of them mentioned that it was a recurring problem with this model car and the problem was an issue with the master cylinder's design.
Fuel gauge shows 1/4 tank but it is empty. This caused the vehicle to stall on the highway. Very dangerous situation could have occurred. Was able to find safety beside the highway but thankful it did not happen in the middle of a busy highway.
My airbag light stays on constantly. There is a knocking sound that occurs as well when I'm driving. I'm concerned if I'm involved in a collision my airbags will not deploy. I contacted infiniti and was told they need to reset it and will cost $800.00 and my extended warranty did not cover it and was not part of the recall list. The ipdm ECM relay switch causes my instrument cluster gauge to go in and out, the check engine light comes on, my truck jerks trying to switch gears, it will sometimes start up after several tries, it causes the RPM's to read over 7 when I'm only driving 60 MPH. It should read between 2 and 3 RPM's. I'm constantly switching the ECM relay plugs to start my truck. The air bag and ipdm ECM relay was not covered under my extended warranty when I purchased my vehicle. This has been going on since I purchased it 4years ago.
