What Problems Does the 2011 Infiniti QX56 Have?
The 2011 Infiniti QX56, while generally robust, does have some frequently reported issues and long-term concerns for potential owners.
One of the most notable problems, particularly for models equipped with it, is related to the Hydraulic Body Motion Control (HBMC) system. This advanced suspension system can develop leaks or other failures, leading to significant repair costs. Owners might notice a spongy ride, uneven stance, or visible fluid leaks if this system is failing. It's a complex system, and a pre-purchase inspection should specifically check for its condition.
Another common complaint revolves around the infotainment system and navigation unit. Freezing screens, unresponsive touchpads, or glitches with the navigation can occur. While sometimes a software update can resolve these, hardware failures might require costly replacements.
Brake components tend to wear relatively quickly due to the vehicle's substantial weight and power, leading to earlier-than-expected replacement of rotors and pads. Some owners also report premature wear of front suspension components like control arm bushings or ball joints, which can manifest as clunking noises over bumps.
Power liftgate motors can occasionally fail, becoming noisy or completely inoperable. Furthermore, due to the direct injection engine, some owners report concerns about carbon buildup over time, which can affect performance and efficiency, though this is less prevalent than in some other direct-injection engines.
Regarding recalls, the 2011 QX56 had a few notable ones:

Regarding recalls, the 2011 QX56 had a few notable ones:
- A recall (NHTSA Campaign Number 16V244000) for a potential issue where the hydraulic power steering hose could detach, leading to a loss of power steering fluid and power steering assist.
- A recall (NHTSA Campaign Number 12V393000) concerning the driver's side airbag inflator, which could fracture during deployment, potentially causing injury. This was part of a broader industry recall related to Takata airbags.
How long will the 2011 Infiniti QX56 last?
With proper and consistent maintenance, a 2011 Infiniti QX56 can reliably achieve 150,000 to 200,000 miles or more, often providing 10 to 15 years of service. Owners who adhere to the recommended service schedule, including timely oil changes, fluid flushes, and addressing minor issues promptly, tend to experience greater longevity. The VK56VD V8 engine itself is generally very durable. However, long-term weaknesses often revolve around the Hydraulic Body Motion Control (HBMC) system, if equipped, which can fail after 8-10 years and be very costly to repair. Infotainment system glitches and wear items like suspension bushings and brake components also become more prevalent with age and mileage, requiring attention to maintain the vehicle's premium feel and performance.
What Technology & Safety Features are Included?
The 2011 Infiniti QX56 was well-appointed with a suite of built-in technology, entertainment, and safety features, reflecting its luxury SUV status.
Standard Technology and Entertainment:
The cabin boasted a standard Infiniti Hard Drive Navigation System with an 8-inch color touchscreen display, voice recognition, and NavTraffic/NavWeather. A 13-speaker Bose Premium Audio System with a 9.3GB Music Box hard drive, Bluetooth hands-free phone system, USB connection port, and satellite radio provided comprehensive entertainment.

2011 Infiniti QX56 Prices and Market Value
When new, the 2011 Infiniti QX56 had an MSRP starting around $57,000 for the 2WD model and approximately $60,000 for the AWD version, before options and destination charges. Fully loaded models could easily exceed $70,000. Today, in the used market, prices typically range from $10,000 to $18,000, depending heavily on mileage, condition, optional packages (like the Deluxe Touring or Technology package), and geographical location. This represents significant depreciation, which is common for large luxury SUVs due to their high initial cost, fuel consumption, and higher maintenance expenses as they age. Factors like a clean title, comprehensive service records, fully functional advanced features (especially the HBMC system), and a well-maintained interior/exterior positively impact its resale value, making it an attractive used purchase for those seeking luxury at a discount.
2011 Infiniti QX56 Cost of Ownership
The 2011 Infiniti QX56 is generally a costly vehicle to own over the long term. Insurance premiums tend to be higher due to its luxury status and repair costs. Fuel costs are substantial, given its 14-16 mpg combined rating and requirement for premium gasoline. Maintenance, while manageable with consistent service, uses luxury-grade parts and labor rates. Repairs, especially for advanced systems like the HBMC suspension or complex electronics, can be very expensive, potentially running into thousands of dollars. Expect to spend significantly more than on a non-luxury SUV. Budgeting for these higher operational expenses is crucial for prospective owners to avoid financial surprises.

How Does the 2011 Infiniti QX56 Compare to Other Sport Utility Vehicle?
The 2011 Infiniti QX56 competes in the full-size luxury SUV segment, squaring off against formidable rivals such as the Cadillac Escalade, Lexus LX 570, Mercedes-Benz GL-Class, and the Lincoln Navigator.
In terms of Performance, the QX56's 400-hp 5.6L V8 and 7-speed automatic transmission provide robust acceleration, often feeling more athletic than the Escalade's 6.2L V8 and the Navigator's older 5.4L V8. The Lexus LX 570, while smooth, typically feels less potent. The optional Hydraulic Body Motion Control (HBMC) system also gives the QX56 a distinct advantage in handling prowess over most body-on-frame rivals, significantly reducing body roll.
Regarding Features, the QX56 was exceptionally well-equipped for its time, often standardizing items like navigation, a Bose sound system, and a power liftgate that were optional on some competitors. Its interior quality, with premium leather and real wood trim, is competitive with Lexus and Mercedes, often surpassing the Cadillac and Lincoln in perceived luxury and build quality for the equivalent model year.
For Reliability, the QX56 generally holds up well, with the V8 engine being a strong point. However, it can be overshadowed by the legendary reliability of the Lexus LX 570, which is often considered bulletproof. The QX56's main Achilles' heel for long-term reliability is the potential for costly HBMC system failures, and some infotainment glitches. The Escalade and Navigator have their own sets of common issues, often related to electronics or air suspension.
In terms of Price, especially in the used market, the QX56 often represents a strong value proposition. It typically undercuts the Lexus LX 570 significantly and can be found for similar or even less than comparable Cadillac Escalade or Mercedes-Benz GL-Class models, despite offering a comparable or superior feature set and performance.
Similar Alternatives: If rock-solid reliability is paramount and budget allows, the Lexus LX 570 is a superior choice, albeit usually at a higher price point. For a more car-like ride and slightly better fuel economy (with diesel options), a used Mercedes-Benz GL450/GL550 could be considered, though its maintenance can be equally, if not more, expensive. The Cadillac Escalade offers a bolder American luxury statement and often more readily available parts, but generally doesn't surpass the QX56 in refinement or performance for this era.

Final Verdict: Is the 2011 Infiniti QX56 a Good Sport Utility Vehicle?
The 2011 Infiniti QX56 is ideal for the buyer who needs a powerful, spacious, and luxurious full-size SUV for family hauling, long-distance travel, and significant towing, but doesn't want to pay new luxury SUV prices. It's definitely worth buying on the used market, where its significant depreciation makes it a luxury bargain. However, strict conditions apply: prioritize models with full service records, especially verifying the condition of the Hydraulic Body Motion Control (HBMC) system if equipped. A pre-purchase inspection by an Infiniti specialist is non-negotiable. Opt for well-maintained examples, ideally with the Technology and Theater packages for maximum features. Be prepared for higher running costs for fuel and potential repairs, typical of large, older luxury vehicles. It's a rewarding purchase for those who understand and budget for its quirks.
