When engaging or disengaging 4 wheel drive low, remember to have the transmission in the neutral position or it will indicate it is engaged, but it won't be.
I know that brake systems and fuel systems are quite different functionally, however I have had a similar problem with my brakes for about 3 years - brakes make nose when pushed, brake and ABS lights come on. I go to the side of the road, turn off the car, turn it on again, and the problem disappears. I had always felt that it was some controller in the car that was having a glitch of some sort. This fuel problem is very reminiscent of the same kind of activity - seems like an electrical/control problem, and turning the car off and then on again makes it go away. Both problems happen only occasionally, and the dealer has never been able to reproduce the problem and consequently never able to fix it.
However, I called Infiniti Consumer Affairs - 1-800-662-6200 option 7 and told them of the issues. The dealer called yesterday and said that Infiniti had instructed them to check out a control module as well as the fuel pump. I received a call this morning indicating that they are going to replace the fuel pump and the IPPM ( a control module). The IPPM is evidently involved with both the fuel system and the brake system. Infiniti is going to cover the cost of replacement.
If you don't hear from me, the problems have not reoccurred. I'll reply again if I continue to have problems.
Good luck - hope you can solve the problems on your vehicles.
Aside of all the problems (paint, brakes, rattles, etc.) should I buy one or stay away? I can check to see if the brakes have been replaced and hear for rattles, but what is the bottom line?
Thanks for your input.
My needs are third row, heated second row, 4WD, sunroof, DVD, and Nav. I know, "gee that all??" So like I said I was originally looking at Denalis, Tahoe LTZs, Yukons.
Anyone have a good suggestion?
Thanks, you guys are the best!
I thought I would chime here re. a used QX56. Take a look at my other posts in the "problems" thread re. A/C in the QX56. To make a long story short, I recently bought a 2009 QX56. On days above 95 degrees in TX, the air at the front vents would not get below 60 degrees, whether moving or idle. In the rear, it was about 70 degrees. Those temperatures sound low, but in a car, it was like an oven in that thing. Normal, industry-standard A/C temp range at the vent should be between 38-48 degrees using recirculation mode after about 10 minuites. Later I test drove a brand new 2010 to double check A/C performance in the QX56 and got the exact same readings with my A/C vent thermometer - about 60 at the front vents, 70 in the back. Thus, the QX56 is a very hot vehicle with a poor A/C. I took my 09 to the dealer for repair, and after 2 days of tests they said it was running as well as possible, and the problem was the outside temperature. [However, one of the techs revealed to me that they have had a lot of customer complainte that the QXs "just don't blow cold enough."] To me, this was unacceptable since my 2003 Yukon (also a big vehicle), my wife's Volvo XC90, and my father's 1998 Lexus 470 each got down to about 40 degrees at the vent under the same conditions. Thus, I ended up returning the QX56 and purchasing a new Yukon instead (from the same family of dealers - I really appreciated this). It was a hard decision because I preferred the bells and whistles of the QX56, but in the end I couldn't sacrifice A/C performance. My new Yukon hits 40 degrees at the vent even on 100+ degree days.
The lack of A/C in the QX56 appears to be a major design flaw that Infiniti should address. My advice is before purchasing a QX56 (or any vehicle for that matter), test drive it for 10 minutes on a hot day and stick an A/C thermometer in the front center vent (they sell them at Autozone for about $5). If the air gets down to 38-48 degrees, the A/C is fine. But if it is 60 like the QX56 I had, I would stay away. That thing was like an oven. GMC's may not be as pretty, but they sure have a great A/C, which in the end is worth a lot more than the other bells and whistles.
Thanks for your help!
There is a lot of cu.ft. interior space in this SUV to cool down and I find the speed at which it aquires a comfortable temp. appropriate for it's size.
Good luck to you if you decide to pull the trigger.
I'd also like to know whether anyone else has had this happen. Anyone?

I can't find dimensions yet, if anyone knows them can you post?
I also heard it is debuting in NYC next month.
Nice little write up...
Looks like the price for 2011 QX is roughly the same as previous generation. How is it possible to add whole bunch of new features without adding much $$ ? Is it because car makers have a huge profit margin to begin with?
about the price, think like the German. make everything optional. that will make the QX start at under $40k.
Looking for best option for all rows and cargo area...
