Infiniti QX56 Problems and Solutions

I have a 2008 QX56 with intelligent key. This morning I can not start the vehicle. Has anybody had this problem? The remote will lock and unlock the doors, but the ignition switch will not rotate from the "lock" position and the dash light flashes the car and key symbol. It is Sunday and Infiniti roadside assistance says they will tow it tomorrow to my dealership because they need a dealership signature to drop off the car and nobody is there on Sunday.


  • Has anyone else experienced this? I was traveling on the freeway in my QX56 with my 6yr old in the back, when an earsplitting explosion occurred...I could feel the pressure from it in my eardrums. My first thought was that an explosion (natural gas storage?) had occurred nearby, alongside the freeway...then I felt the shards of glass raining down inside. I thought at that point that perhaps we'd been shot at. Wind and glass are rushing into the vehicle, my daughter is screaming, and I am desperately trying to maintain control of the vehicle and comprehend what is happening to us at the same time. Luckily for us, no one was hurt, but this could have had a much more grisly outcome. I have photos showing that all the glass remaining around the edges of the sunroof is curved upward, as if there were an interior pressure that the glass could not withstand. The dealership said I had to pay for the repairs, (@$1000) though the vehicle was almost new and under warranty. I would like to hear from any owner of an Infiniti or Nissan who has had a similar experience. Thanks.

    That sounds pretty scary! Though not related to Infiniti, you may be interested in reading about similar experiences others have had: Exploding Sunroofs!

    For what it's worth, I don't see why it wouldn't be covered by warranty.

  • Hello Tidester,
    Yes, I just had the same problem with my brand new 2007 G35X. I too was driving on the highway traveling about 65mph when my sunroof exploded. Glass shattered and sunroof exploded up and out - very scary!! My car is currently at the dealership pending an explanation. This is ridiculous me and my passenger could have been killed had I not took control of the car. Infiniti is still trying to figure out what the problem was. Clearly a manufacturing defect. Has anyone else out there experienced this problem - please post.

  • This exact same thing just happened to my wife. This is on a 2008 qx56. I am taking it in tomorrow as it happened over the weekend. I can tell you one thing, if they tell me that I have to pay for the repairs, there will be a picket outside of the dealership. My car has 4K miles on it. Exactly what you explained here is what happened. I did a google search before I brought the vehicle in to see if this has happened before. Thanks for posting!
  • Sorry about the Q's exploding sunroof! Other than that, would you say you are happy with the Q? I am considering purchasing one for my wife!
  • I've seen nothing but good reviews from owners and from sites that reviewed the QX. I see where people have talked about exploding sunroofs which is a serious problem, but these may just be a few isolated events. I hope. Anyhow I'm stuck between an Escalade and the new QX. I'm leaning towards the QX.
  • Does anyone know why Infiniti has not incorporated projectors into the QX HID set up? I love the beam pattern from Nissans/Infiniti models and I also adore GM's HID in the 07 Escalade which uses projectors. Why doesn't infiniti use them on the QX, you figure the beam pattern would go everywhere and not focus on the road correctly. Anyone know about this?
  • I just got a brand new 4x4 QX56 out of the dealer yesterday. Today after driving 10 miles and parking, when I re-started the engine I noticed the the front A/C unit began to swtich on & off intermittently. A few minutes later the front fan and A/C unit stopped working. I noticed a faint "burned-circuit" smell inside the cabin at the time. I was not able to restart the A/C unit. The back unit seems to be working fine, yet not enough to keep us comfortable. Has anybody seen something like this? Any ideas? I checked the fuse boxes but there isn't a slot for the "front- A/C unit or blower" and the information in the manual is scarce. Thank you. -Julio :confuse:
  • Whoa. That should not happen. We just purchased a brand new QX56 on the 12/31 and no problems at all thus far (except the salesperson was/is a jerk). I would definitely return the truck immediately for a new truck or to have it repaired immediately. Let us know what happens.
  • Thank you for your solidarity :) It didn't take me long, I took the damaged unit back to the dealer for a new one. Sure enough, I got one in 30 min. Later I was told that this unit was taken back to the sales floor after 4 hrs at the repair shop. And that the malfunction was due to a couple blown-out fuses. I'm still thinking why did it happen? A voltage regulation problem, or a short circuit of some kind? Who will ever know? I honestly doubt the “fuse story" very much as I finally got a chance to check all the fuses, one by one, before turning the unit back in, and I couldn't find anything wrong with them. The salesperson that took care of our case was very supportive and helped us to get out of the problem without arguments very quickly (A+)! - Thank you, JR

    ^^^ So they essentially exchanged you a new QX with no issues? Wow...very impressive from your dealer. I would have gone in expecting a battle and been blown over with a feather when they did not buck me!!!

  • Yep! No if ands or buts. JR
  • Hello, I own 06' qx56 and also leasing a fx35 and was wondering if anyone else isn't satisfied with the ride quality on the qx56. I've been in a scion with better ride quality. I love my truck but the suspension isn't what I expect it from day 1. I had the dealer check my suspension and was told its fine (told me yeah thats air suspension). As i'm traveling on the highway doing 50-65mph going over bumps or imperfection on the road the car would jerk and rattle to one side. Is this normal??? What could be the problem??? Also recently as I go over a speed bump or if the car goes up a small bump or hill on the road and the front end slams down (with my windows open) I hear something crumpling, sounds like a 2 liter plastic bottle being steped on(crushed). Has anyone else experience this??? One more thing ... driving with your window down 2inches or so...does your window rattle as if it felt loose???

    I posted in the old thread, but thought I'd post here as more traffic. I have a 05 QX that the seats don't always return to postion. It never happened for the first 1-1 1/2 yrs and is increasing in frequency. I have thought about whether I hit seat adjust buttons when exiting or entering, but since it never happened in the beginning, I can't believe I'm hitting them that frequently now. Happens 3-4 times per week but of course never at the dealer.....thoughts???

    I currently own a GMC Yukon and a Ford F-150. Both have day time running lights, came on Yukon, had installed on F-150. I own a 08 QX56 and wonder if running lights can be installed. I read , rather let me say, I scanned , the owners manual and I don't believe that QX56s sold in the U.S. come so equipped. Question is whether any readers had running lights installed after purchase.
    I just turned 1200 miles and I really enjoy the car when my wife lets me get behind the wheel. Both my F-150 and Q56 are black which sort of led me to order the Zaino Kit, for $86.00 , to see if I get the POP! that readers speak of. I must now build up my courage, stamina, and what else I need muster up to attack a 6 hour task.

    Do the Zaino....Do the Zaino....Do the Zaino :)

    and what else I need muster up to attack a 6 hour task.

    6 hours to Zaino? I did the dawn, clay, to z-5 on a Yukon Denali in little over an hour. Course if you're doing a 6 pack an hour I can understand why it would take you 6 hours.

    I'm new to the forum, I'm just wondering did you buy a Q? I just traded in my 04 for an 08.

    I have a 2006; and you are right. QX in US does not come with DRL. Since I always want one, I went back to the dealer and ask for it. What they did was to put a DLR module which hooked up to the HID.

    To further the discussion, I asked them why the HID. They explained to me that the QX in US does not come with the harness that allows DRL by simply switching a fuse (like my brothers BMW X3). They did that to the fog light in the past; but had a lot of complains about frequent replacement. HID on the other hand is more long lasting. Of course, I won't be able to tell until maybe 100,000 miles later. Theoretically, it should be the case.

    It costed me about $400 to do it. Hope this helps!
