very nice lux suv...great size and comfort. if you are looking from a great family hauler and can handle the 12mpg than choose this. the qx is loaded with several things other brands are just starting to do...a great example is the rearview camera which cadillac/gm/others dont do

Very un-japanese in quality!

This vehicle was purchased new in March 2005. My family and I had nothing but problems with this vehicle. We had many engine issues that Santa Monica Infiniti repaired many times and finally my family decided to work with an attorney since this car had so many repairs and many recurring problems and we believed it qualified for remedies through the lemon law. Through persistence and working closely with our attorney Infiniti finally had to buy the car back and give us monetary remedy. We then bought a 2007 Escalade ESV to replace this unsatisfying beast. Infiniti gave us the money in February 2008 after the lemon law buyback.

To many bugs

Vehicle: 2005 Infiniti QX56 4WD 4dr SUV (5.6L 8cyl 5A)

I bought it in 2007 and since then have had to many bugs in the car like, backup camera failure, seat belt tensioner replacements, airbag light blinking,air pressure leveler failing, brake problems, rear hatch opening by its self, front axle joints making noises, tire air valves failing and so on. I spent like over 5000 big ones already on a car less than 5 years old.

What a wonderful truck

Most of the time, the QX56 has felt very smooth on the road and has been extremely comfortable on long hauls to Mammoth. Comfort is great, but still a body on frame truck. Roomy all around. Great 2nd row - limo- like room. Same height and width, but the extra 8" length over the Yukon are surprisingly noticeable. The kids love it room for them, friends, and groceries. Tows like a champ, very comfortable on long trips. The 4wd system is great. No problems in 4 feet of snow or in light off-roading. Having a 4x4 lo range also sold us on this beast. After one year and 20k miles we are very happy. Currently 95k and counting.

75000 miles and still great!

After 4 1/2 years and 75K miles, this vehicle cannot be beat. We drive locally, long distance, in snow, heat and traffic. We couldn't ask for a better ride, fit finish and overall reliability. All we do are regular oil changes, tire rotations and scheduled maintenance and this truck runs great. We had an unfortunate experience hitting a VERY large deer once, and had we been in anything else, the deer would have been in our laps. We were safe, the deer escaped, and all we had to replace was the front grill and hood. Insurance covered it. Even all the toys (DVD system, Navigation, Sirius, power lift gate) remain in great working order. We love this SUV, and the paint still shines like new!

I am also considering a qx56 2005 vs 2006. I saw some of you post today that you are waiting for the 2006's. The 2006's have just come in because I looked at one today. (I live in Houston) It still...

After reading all the reliability issues with QX56 on this board, I still decided to trade my 2002 Sequoia in and purchase a 2005 QX56 for $8,000 off MSRP. I learned that any 2005 QX56 built after Ma...

Funny story...My 2005 QX56 experiences this "memory lapse" from time to time, though I just put up with it, and manually adjust my seat & steering column when it happens. Right now, how...
