Experiencing almost identical issues to another complaint I saw that was previously filed (#10924936). Told we need to replace catalytic converters at $2,000 each. Dealership said it's a known issue with the vehicles. If it's a known issue, perhaps something should be done about it. We've also had to have the battery replaced numerous times. Had to call aaa several times to jump the vehicle.

We have had problems with the battery since we bought the Qx56. SUV's completely dies after a glove box light, radio has been played for 20 to 30 minutes, car cannot be jumped by typical cables, every time we either had to have a heavy duty jump done by tow company or battery was replaced by Infiniti. Timing chain and both catalytic converters need to be replaced, with engine issues. Infiniti had SUV for almost a month to fix engine and timing chain. Engine light still coming on then we where told the converters needed to be replaced. $5k to fix. It sounds like this is a very common issue with Qx56 for this year and others. After each time engine light came on Infiniti service dept told us to continue driving the car and after 2 weeks if it didn't reset then call back again. We did this reluctantly, because I am my wife have been taught that when you have an engine light come on, stop call, and get the vehicle in to be inspected.
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.

I replace my altanator and always had a problem with the rpm gauge? it dose not move or sometimes stays at the 6/7 and as of recently the car looses power and almost crashed on the freeway also I bought this car in 2014.
All of the passenger door locks have stopped working. The only way to get into the vehicle is to use the key fob to roll down the windows, so that a door can be manually unlocked. The interior electric door lock mechanisms do not work either.
During normal operation of the vehicle and while in motion, the abs brake light indicator on the dash control panel illuminates when applying the brakes, which cause the brakes to shake and make scraping sound. At that point the brakes fail to stop the vehicle in a safe distance, increasing the chance of a collision. Abs brake light clears and normal brake functions return when the ignition is turned off, then back on.

Airbag light suddenly began flashing. I took truck to dealer and they said driver side airbag module shorted internally. Price to fix is $1,600. 00. This truck has never been in an accident or at any time had its airbags deployed. All service to truck has been with Infiniti dealerships. Service representative said electronic issue and not owner error. This could happen at any time with this truck. I called customer service and they said problem is covered if truck less than 4 years old or 60,000 miles. This is an electronic manufacturing defect and Infiniti should not charge for their electronic defect affecting safety. All airbags in vehicle are now disabled. Take responsibility Infiniti. Your coverage of functioning airbags should last the lifetime of your vehicles.
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 rread 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!.
The vehicle died when at a stop light and rolled back hitting the car behind us. I looked on your website and apparently it was caused by a faulty engine control module (ecm) in the intelligent power distribution module (ipdm). This appears to have been recalled on all 2004 to 2006 Infiniti Qx56 vehicles, however, I received no such notice and Infiniti says their is not recall associated with my VIN number. I believe my VIN number was left out in error and this should be recalled. This vehicle has also lost power a number of times while driving, but those incidents didn't result in an accident (luckily). Thank you.

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!.

While driving on the freeway I noticed that the tachometer continued rising instead of going up and down with the speed. By the time I got home the gauge was facing straight down, stuck in that position. I turned the car off and on to see if it would change the gauge, but nothing happened. Next I put the can in park, set the parking brake and hit the accelerator and the gauge began to slowly move backwards, after doing this a few times the gauge moved back around slowly. After doing this 5 times the gauge is just to the left of the red area. No problems with the battery, it is only 4months old. The transmission felt as though it was shifting propery, and there is not a check engine light on or any other problems besides the gauge.
On July 1, 2012 I was driving on highway 156 in winston-salem n. C. When my air condition, turn signal, speedometer stop working and check engine light can on. We were on vacation driving through north carolina from georgia. It was Sunday and we decided to stay overnight to have the Qx56 infinity checked out the next day for safety reasons. The next mourning on our way to the infinity dealership, the 4 wheel drive can on and locked up the transmission and stopped moving. We were on highway 156 downtown winston-salem on Monday mourning in rush hour traffic stopped. I manage to easy it off the road and called aaa to tow me to the dealership. I have taken this vehicle to other dealerships in jonesboro GA. And then in huntsville al before my trip because of the service light coming on. My family and I was very lucky we were not killed. I feel this vehicle got some very serious safety problems that must be check out before anything major happen that may hurt or kill someone. This 2004 Qx56 infinity have been recalled many times for repairs since I purchase it in 2004. Because of pass experiences with this vehicle, I feel there may be more serious defects in this vehicle.
My 2004 infinity q56 engine cuts off going down the road. Dealer is aware of a problem with several year models doing this same thing. All power is lost brakes , steering ect. Have had 4 computer boards replace and going back for another try oct. 25-2010. Infinity consumer affairs has been contacted but even though they are concerned they are not sure of a fix. What will it take to get help, a bad crash or two? if you type in problems with q56 cutting off while going down the road you will see that the internet has a group of people experiencing this same scary issue. Thank you for looking into this. I myself have had a few close calls trying to get the car off the road safely. First incident June 2007 last incident oct. 20 , 2010.

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.
This letter is in reference to a previous complaint filed with Infiniti consumer affairs on December 3, 2009, regarding my vehicle shutting completely down, stalled out, not moving in the drive or reverse position at a busy intersection on a rainy stormy evening. This occurrence could have caused a serious accident or worse, a fatality. As a result of police assistance and having my vehicle towed directly to the dealership, to date there are no mechanical issues found by the dealer related to my vehicle shutting down at the intersection. My complaint contains additional serious vehicle issues regarding my headlights, instrument cluster/panel, and the fuse box under the hood. Both headlights on my vehicle suddenly stopped working at the same time. The bulbs were replaced and the headlight fuses were found to be functioning. The instrument panel/cluster light blinks constantly as I drive and the panel/cluster gauges are completely not functioning properly. Fuses have been checked under the vehicle’s hood and results indicate some of the 10 amp fuses are not functioning at all. I am concerned that there should have been a safety recall regarding my 2005 Infiniti qx 56, which appears to jeopardize my safety. There are no legitimate answers or explanations as to why my vehicle’s headlights are not working, the cluster/panel has malfunctioned, or why some fuses underneath my vehicle’s hood are not functioning. As a result of my vehicle’s expired warranty and mechanical failures, I have consumed a great deal of out-of-pocket expenses, including a traffic citation regarding my headlights. I am limited and inconvenienced to driving my vehicle at night as a result of my inoperable headlights which can cause me great harm. I am requesting that my situation be given serious immediate attention and resolution.
