What Problems Does the 2007 Infiniti QX56 Have?
The 2007 Infiniti QX56, like many vehicles of its era and class, can experience certain recurring issues that prospective buyers should be aware of. One of the most frequently cited problems relates to the transmission. Owners have reported issues such as rough shifting, slipping gears, and premature failure, often requiring costly repairs or replacement. While not specific to the 2007 model year, transmissions in these large SUVs can be a weak point if not maintained diligently.
Another area of concern is the air suspension system. The QX56 often features an auto-leveling rear air suspension, and components like air springs, compressors, and lines can degrade over time, leading to a sagging rear end or an inability to maintain ride height. This can be an expensive repair.
Electrical gremlins are also not uncommon. This can manifest in various ways, including malfunctioning power windows, power locks, infotainment system glitches, or issues with interior lighting. The complexity of the vehicle's electronics, especially with optional navigation and entertainment systems, can contribute to these problems as the vehicle ages.
Some owners have noted issues with the power steering system, including leaks or a noisy pump. While less common than transmission or suspension issues, it's something to check during an inspection.
Fuel injectors can also become clogged or fail over time, leading to rough idling, misfires, and reduced engine performance.
Regarding recalls, it's essential to check the NHTSA website for any specific recalls issued for the 2007 QX56. Historically, recalls for vehicles of this type might involve issues with airbags, braking systems, or potential fire hazards. For the 2007 model year, some recalls could have pertained to the fuel system or even potential issues with the steering column.
In terms of long-term reliability, the QX56 is generally considered a robust vehicle, but its complexity and size mean that repairs can be more involved and expensive than with smaller cars. Regular and thorough maintenance, including fluid changes for the engine, transmission, and differentials, as well as inspecting suspension and braking components, is paramount to ensuring longevity and avoiding major headaches.

How long will the 2007 Infiniti QX56 last?
Based on owner data and maintenance habits, a well-maintained 2007 Infiniti QX56 can reasonably achieve 200,000 to 250,000 miles or more. These vehicles are built with a robust underlying structure and a powerful V8 engine designed for longevity. However, their long-term durability is heavily influenced by the owner's commitment to regular maintenance. Key weaknesses that emerge over time include potential transmission issues, degradation of the air suspension system, and various electrical component failures. Addressing these proactively, especially transmission fluid changes and suspension inspections, can significantly extend the vehicle's service life and prevent more catastrophic failures. Neglecting these areas can lead to premature and costly repairs, diminishing the vehicle's overall lifespan.
What Technology & Safety Features are Included?
The 2007 Infiniti QX56 offered a respectable suite of technology, entertainment, driver-assistance, and safety features for its time, aiming to justify its luxury positioning.
Standard Technology and Entertainment features often included a premium Bose audio system with an in-dash CD player, and steering wheel-mounted audio controls. Many models came equipped with a color information display and dual-zone automatic climate control. Power-adjustable and heated front seats were standard, enhancing comfort.
Optional Technology and Entertainment features significantly elevated the QX56's appeal. A high-end navigation system with a touch-screen interface was a popular upgrade, often bundled with a rearview camera for easier parking and maneuvering. For families, the optional rear-seat entertainment system, typically featuring dual screens and a DVD player, was a major draw. Bluetooth hands-free phone connectivity was also available as an option, adding convenience.
Driver-Assistance Features were somewhat limited by today's standards but included features like cruise control and a tire pressure monitoring system. The standard rear-view camera, while basic, provided a helpful aid. Parking sensors were sometimes included as part of option packages.

2007 Infiniti QX56 Prices and Market Value
When new, the 2007 Infiniti QX56 had an MSRP that typically started in the high $50,000s and could easily climb into the $60,000s with optional packages and all-wheel drive. As with most luxury SUVs, it experienced significant depreciation in its early years.
Currently, on the used market, the 2007 QX56 can be found in a wide price range, often between $5,000 and $15,000, heavily dependent on mileage, condition, and location. Lower mileage, well-maintained examples with desirable options will command higher prices.
Factors affecting resale value include the vehicle's maintenance history, the presence of known mechanical issues (particularly transmission and air suspension), the overall condition of the interior and exterior, and the number of previous owners. The V8 engine and towing capacity are still attractive to some buyers, but the poor fuel economy and potential repair costs can deter others, contributing to its lower resale value compared to more fuel-efficient or compact vehicles. The availability of desirable options like navigation and rear-seat entertainment can also positively influence its market price.

How Does the 2007 Infiniti QX56 Compare to Other Sport Utility Vehicle?
The 2007 Infiniti QX56 competed in the highly contested full-size luxury SUV segment against formidable rivals like the Cadillac Escalade, Lincoln Navigator, and the Lexus LX 570 (though the LX 570 was redesigned for 2008, its predecessor was a key competitor).
Performance: The QX56's 320-hp 5.6L V8 offered strong acceleration and impressive towing capacity (9,000 lbs), rivaling or exceeding many competitors. The Escalade also offered robust V8 power, while the Navigator often lagged slightly in horsepower but provided a smooth ride. The Lexus LX 570 was known for its ruggedness and capable off-road performance, though often with less on-road sportiness.
Features: Infiniti consistently loaded its vehicles with luxury features. The QX56 offered high-end interiors, navigation, rear-seat entertainment, and a premium sound system, often matching or surpassing the Escalade and Navigator in terms of standard and available amenities. The Lexus LX focused more on luxury and capability, perhaps with slightly less emphasis on cutting-edge tech features compared to the QX56.
Reliability: This is where the QX56 faces challenges. While the engine is generally robust, the QX56 has a reputation for potential issues with its transmission and air suspension, areas where rivals like the Lexus LX 570 often held an advantage in long-term durability and fewer costly repairs. The Escalade and Navigator also had their share of reliability concerns, but perhaps less so in the specific areas of QX56's known weaknesses.
Price: When new, all these vehicles were similarly priced, falling in the premium luxury segment. On the used market, the QX56 often presents a more budget-friendly entry point than a comparable Escalade or LX 570, especially considering its initial depreciation.
Alternatives: For those prioritizing reliability and long-term value in this segment, a used Lexus LX 470 (pre-2008) or an earlier Toyota Land Cruiser (which shares the LX's platform) would be excellent choices, albeit with potentially less modern interior tech. A well-maintained Cadillac Escalade could be a strong contender if its specific reliability quirks are less concerning. If extreme towing is the absolute priority and luxury is secondary, a Ford Expedition EL might also be considered for its spaciousness.

Final Verdict: Is the 2007 Infiniti QX56 a Good Sport Utility Vehicle?
The 2007 Infiniti QX56 is best suited for buyers seeking a spacious, powerful, and luxurious full-size SUV with strong towing capabilities at a significantly reduced price compared to its original MSRP. It's ideal for families who need ample passenger and cargo room, or for those who frequently tow large items.
It is worth buying, but with considerable caution, primarily on the used market. A thorough pre-purchase inspection by a mechanic familiar with these vehicles is essential, focusing on the transmission and air suspension. Avoid buying new, as its value depreciates rapidly. Specific trims are less critical than overall condition and maintenance history. Buyers should be prepared for higher fuel and potential repair costs. If reliability is the absolute top priority, other luxury SUVs might be a safer bet, but for those who can find a well-maintained example and are aware of its potential pitfalls, the QX56 offers a lot of luxury and capability for the money.
