This is a Warranty repair the dealer will perform for free. It appears to be common problem.

i had the same problem with the 2006 Q56....the U joint in the front drive shaft has gone bad and needs to be replaced.
This is a warranty item...dealer replaced mine. you will need the Front Drive Shaft Assembly and a Propellar Shaft. This repair and parts were covered under warranty

you need to have the dealer replace the front drive shaft assembly. The U joint has gone bad and deteriorated. They should do this work under warranty.

A/C Problems?

My 2009 QX56 does not appear to cool properly. Right now we are hitting highs of 100 degrees in TX. My QX56 only cools to about 60 degrees at the front center vent (I am measuring temps with a special A/C thermometer designed for this purpose). At the same time of day, my 2003 Yukon hits 45 degrees at the vent and my 2007 Volvo XC90 hits 40 degrees! I think the QX56 should hit similar numbers. Has anyone experienced a similar problem with the QX56 producing cool, but not cold, air? Is this a programatic issue? I took it to the dealer and they said everything was fine with the vehicle.

In addition to the temperature of the air conditioner's output, the other factor that matters is the flow rate (volume) of the output. For example, if your QX56 is putting out twice the volume at 60° as your XC90 puts out at 40° you may be just as comfortable in your QX56.

Since your QX56 is larger it may not cool the cabin to 40 degrees because the cool air has a larger area to cool. And since your SUV is larger it also produces more heat (when driving) which in turn will cause it not to cool up as fast. Then again maybe the vehicle was built to cool only to only 60 degrees. While test driving two other new vehicles I noticed they only cooled to 60 degrees also. Cooling the vehicle to 45 degrees will probably affect the MPG (which is already bad) which is why it stops at 60. I hope this helps.

Thanks. So are you and Tidestar opining that perhaps 60 degrees is correct? The ambient temperature is comfortable in the cabin when outdoor temps are below 95. But above that, it is stuffy. I realize it is hot and A/Cs struggle to keep up, but even at 105 degrees, my Yukon and Volvo get the cabin cold. I think a $60,000 QX56 should be able to do the same, and that this is a design flaw with QX56's. I found a similar line of complaints for the 2005 Nissan Armada. See Nissan Service Bulletin ITB05-041B on the Nissanhelp.com website. Thanks for your responses.

What I wrote was only a suggestion. The proof is in the comfort of the passengers and you're saying that the overall cooling is inadequate. I've never driven a QX56 so I will certainly defer to your hands on experience.
