My 2004 Infiniti QX56 Shuts Off While Driving! Any Help?

[Ronpatz]

Not sure if this is the right forum for this, but I'm hoping somebody may have a solution. I have a 2004 Infiniti QX56 with around 100k miles on it. Up until these past couple weeks, I haven't had any problems with the cara as it has only required standard maintenance. That has changed lately.

I was driving on the highway between 50-60 when the engine, without warning, suddenly shut off. When this happened, the check engine soon, brake light, etc.. sensors began flashing in the dash. I glided into the breakdown lane and shut the car off. I was able to restart it immediately as if nothing had happened. I drove right to the dealership. They felt it may be a sensor problem, so they replaced the sensors. The car drove fine for a week, but today the same problem happened three times on the way home. I don't think the dealer knows what is wrong, so I am hoping someone out there has encountered a similar problem and has a solution? Please help out a fellow Infiniti owner on this one! Thanks

Welcome to NICOclub, glad to have you here in the Armada / QX56 Forum!

I really don't have any ideas, but battery, alternator???? Keep us posted please.

Probably IPDM failing intermittently? The best bet is to swap a known good one & test drive for a long period of time.

My 06 shut down a couple weeks ago (no warning) dealer replaced the fuel sending unit sensors. Ran out of gas, but was reading alittle over half a tank. Seems like they see a couple of those a week. Can you say ethanol?

I experienced same issues as you described last week. It ended up being a bad IPDM (Intelligent Power Distribution Module) and a couple other related items. I am scheduled to pick my QX56 later up today. I hope this is helpful.

I was experiencing where the vehicle would just die. The motor would crank, but not start. It would take a few extra tries and eventually it would start. I was able to make it to the dealer without having to be towed.

I say gHost Ride the whipp........
Just Jokin...
sounds like a common problem.. Should I be concerned...? I tend to go over 50 or 60...hehe.. just can't help it with the smooth V8 ride....

Also it also maybe the chip recognition within the key if you have one... Something with the security, for example, if the key is worn and may come loose in the ignition area and if the vehicle is not recognizing that you have a key in the ignition it may cause it to automatically shut down... or otherwise just make sure you always have a full tank of premium... I always fill it when its have full..... if they dont know whats wrong... Ghost Ride that BiAtch.......

Are you getting a Check Engine light?

i don't get any warning light it just randomly shutsoff and then it turns on right away sometimes other times it takes a couple of tries and then it turns back on

That would lead me to believe it is a fuel issue. If it was anything else you would throw a code... Fuel pump maybe?

i was thinking of changing the intelligent power distribution module. but you think it could be a fuel issue i was even thinking maybe it could be a fuel sensor

Did you get the issue resolved...I'm going through the same thing right now...sometimes will putter as though it's not getting enough gas but mostly it will not start at all now.

ANYONE HAVE ANY SUGGESTIONS...Need to do something. Don't want to waste money on every possible solution.

Well my truck is still at the dealership...it was (you guessed it) the IPDM!!!

It's not under warranty...here's the thing. The part is $150, but for them to run diagnostics and for parts and labor I'm looking at $450. Not too bad considering it won't run without the part being replaced.

Here's the thing...I don't have warranty to cover this or a loaner, BUT I took it to the dealer and the service manager said he would give me a loaner car FOR FREE if I let them do the service.

I let them do it, because the PART IS ON NATIONAL BACKORDER!!!!!!!!!!!

I can't get the part if I wanted to do it myself anyway!!!!!!!!!!!!

I figure if they have it a week, the cost of me not having my truck would be worth the extra $250. So no biggie, in the meantime I get to drive a LITTLE EX35 , but it beats not having my second car.

Thanks for the info...
