After only a few years the frame on this $65,000 full size SUV began to rust.

Very nice

Vehicle: 2008 Infiniti QX56

I have now been driving this Truck for a 2 weeks. I did a small road trip around 400 mile. This truck has a very smooth ride. I would compare to more of a sedan ride. The technology is very user friendly. The cabin is loaded with comfort. The 3rd row is great for little kids which I have. The Dvd is nice and the back cabin heater/ac. The captain chairs in the 2nd row are very nice along with the push button seats. The drivers control area is well thought out. The only real problem with the Truck is the fuel economy. I am getting 11 mpg in city and 16 mgp highway. One has to be able to afford the gas. If you are driving more than 1000 miles a month I would not buy this truck.

2 yrs later- we'd still

Vehicle: 2008 Infiniti QX56

We cross shopped tons of large SUVs (MB GL450, Armada, Toyota Sequoia & Land Cruiser, GMC Denali, Cadillac Escalade, Lexus LX570, ) and this was the obvious choice. The 08 interior upgrade is dramatic and makes this truly feel like a luxury SUV. Lots of technology/luxury (HID lights, keyless start, HDD Navi, Front/Rear Sonar, intelligent cruise control, rear Camera, heated steering wheel, power 3rd row seat etc.) that make this truck feel like a million bucks. The interior is very flexible. We have the bench seat and 2 car seats and can still get 2-3 adults in the 3rd row. We take several trips/year from VA to HH, SC and can get 16/17 MPG even w/Thule box on top. No issues with reliabilty

Amazing truck

The truck is great, I purchased it to replace my 07 EXT due to a baby on the way. I needed something with better crash ratings. The funny thing is that two days after purchasing the truck, a 75FT tree fell across the highway and I had to go through it at 75MPH. If I were to have the GM, I would most likely not be typing this. This truck saved my wife's and my life. I added a remote starter on the truck. A bit pricey, but extremely useful. Also added an I-Pod attachment that plays video and made it so that I can control the GPS and watch video while driving.

The pinnacle

The QX-56 is the best SUV secret out there. Stunning fit and finish inside, and excellent engine -- torque and power (mileage is poor though). We get 13 mpg in city driving and 16 mpg highway. If you drive 55, you'd be able to coax 17.5 or 18 mpg highway. Beautiful leather and wood accents. Electronics are abundant and XM Radio is terrific. Not a "beautiful" car on the outside, but still the best I've owned.

A near-perfect luxobrute

Vehicle: 2008 Infiniti QX56

I've had a series of high-end super SUVs, including Landcruisers, Land Rovers, Lexus LX470, and I tested all of their most recent models before buying the QX56. This Infiniti is the best by far. It is huge on the inside, FAR larger than a Landcruiser/LX570 or Range Rover. Far more luxurious and full-featured than any other large SUV other than the Range Rover. Everything is well thought out. The exterior is handsome, especially the gigantic chrome grill and chrome roof racks. These trucks are rare enough to continually look fresh, unlike say an X5. At 5000 mile it is still solid, rattle-free, and a joy to drive. I don't think there is a better large SUV out there at any price.

What's New for 2009

After significant revisions last year, the 2009 Infiniti QX56 receives no notable changes.


If bling is your thing, you'll find a lot to like about the 2009 Infiniti QX56. Everything from its bold grille to its 20-inch wheels is festooned with mirror-finish brightwork, and the QX56's unorthodox styling makes it stand out amid the sea of cookie-cutter SUVs. Having elbowed its way into an attention-grabbing segment once ruled by domestics like the Cadillac Escalade and Lincoln Navigator, the Nissan Armada-based QX56 remains a viable alternative to these gargantuan American utes, even in the sixth year of its current design.

Last year's revisions have helped keep the QX56 competitive. The revamped interior boasts improved materials quality and a bevy of standard premium features like keyless start and a power-folding third-row seat. There's also plenty of state-of-the-art technology, including a navigation system with voice activation, real-time traffic updates and a hard drive that can store a library's worth of music files for the 12-speaker Bose audio system. As ever, the QX56 is surprisingly enjoyable to drive for such a massive vehicle, thanks to its well-controlled ride and willing V8. And while it's not a segment leader in cargo capacity, it will still haul more people and packages than most other SUVs on the road.

As is often the case with luxury vehicles, choosing the one for your driveway is largely a matter of personal preference rather than objective rankings. If a classy but subdued presence is more your speed, we suggest looking at the Mercedes-Benz GL-Class. If you want the biggest and brawniest luxury SUV on the block, it's hard to top the Escalade. But if you're partial to big, bright and shiny and the domestic luxury offerings seem a bit too traditional, then by all means, express yourself with the 2009 Infiniti QX56.

Body Styles, Trim Levels, and Options

The 2009 Infiniti QX56 is a full-size luxury SUV available in two- or four-wheel-drive versions with standard seven-passenger seating. The comprehensive standard equipment list includes 20-inch chrome wheels, an auto-leveling rear suspension, xenon headlights, a rearview camera, rear parking sensors, a sunroof, a power liftgate, a heated steering wheel, power-adjustable pedals, dual-zone automatic climate control, leather upholstery, power front seats, second-row fold-flat captain's chairs, a power-folding third-row seat and first- and second-row heated seats. The QX56 is also a technological tour de force, thanks to equipment like keyless start, a hard-drive-based navigation system with real-time traffic information, voice-activated electronic functions, Bluetooth connectivity and a 12-speaker Bose audio system with 9.3 GB of built-in digital music storage.

Options are limited to a second-row split bench seat, a technology package with adaptive cruise control and front sonar sensors, a rear-seat DVD entertainment system and a towing package for two-wheel-drive models (standard on 4WD).

Powertrains and Performance

The 2009 QX56 is motivated by a 5.6-liter V8 that produces 320 horsepower and 393 pound-feet of torque. This robust engine is mated to a five-speed automatic transmission in either rear-wheel-drive or 4WD layouts, with the 4WD version offering low-range gearing for tackling serious off-road terrain. The QX56 is relatively quick for such a large vehicle, managing the 0-60-mph sprint in 7.3 seconds. Towing capacity is a beefy 9,000 pounds on properly equipped 2WD models. As is typical for a large SUV, the QX56 gulps fuel at an aggressive rate. EPA estimated fuel economy for a 4WD model is 12 mpg city/17 mpg highway and 14 mpg combined.


The 2009 Infiniti QX56 comes standard with antilock disc brakes with brake assist, stability control, active front head restraints, front-seat side-impact airbags, full-length side curtain airbags, rear parking sensors and a rearview camera. Past models were criticized for weak brakes, but that problem was addressed in last year's refresh, and the QX56's brakes now perform satisfactorily. In frontal impact crash testing, the big Infiniti scored a perfect five stars out of five for driver protection and four stars for the front passenger.

Interior Design and Special Features

The Infiniti QX56's cabin received a welcome and overdue upgrade last year. The redesigned instrument panel and higher-quality materials are more in keeping with this SUV's mid-$50,000 luxury price tag. Real wood, soft leather and creature comforts abound, making the spacious QX56 a comfortable companion on longer trips. The standard seating arrangement includes second-row captain's chairs with a removable center console and a power fold-flat third-row bench. For those who need to accommodate up to eight, a flat-folding second-row 40/20/40 split bench seat is available. However, the QX56 provides a somewhat disappointing 97 cubic feet of maximum cargo capacity -- more than the smaller Lexus GX 470 or Mercedes-Benz G-Class but less than the comparably sized Escalade or Navigator.

Driving Impressions

The 2009 Infiniti QX56 accelerates swiftly both around town and on the highway, with seamless gearchanges and quick downshifts for overtaking slower traffic. Its fully independent suspension provides an impressive trade-off between a well-damped luxury ride and sure-footed handling. There's a significant amount of body roll during cornering, but that's to be expected when pushing nearly 3 tons of luxury and utility through twists and turns.
