What Problems Does the 2006 Infiniti QX56 Have?
The 2006 Infiniti QX56, while generally robust, is not without its reported issues. A significant concern that surfaces across various model years of this generation is the premature failure of the transmission. Owners have reported that the automatic transmission can begin to slip or fail entirely, often around the 100,000-mile mark. This is a costly repair, so buyers should be wary of any transmission symptoms. Another frequently cited problem is related to the timing chain. While not as common as transmission issues, the timing chain tensioners can wear out, leading to rattling noises from the engine and potentially more serious engine damage if not addressed. The suspension system is also a point of attention; owners may encounter worn-out struts, shocks, or bushings, leading to a less comfortable ride and potential handling issues. Electrical gremlins are not uncommon in luxury vehicles of this era, and the QX56 can experience issues with sensors, power windows, door locks, and the infotainment system. The rear liftgate actuator is another component that has been known to fail. Regarding recalls, it's essential to check the National Highway Traffic Safety Administration (NHTSA) website for any applicable recalls for a specific VIN. For the 2006 model year, recalls have been issued for issues such as potential fuel leaks from the fuel tank strap, and a defect in the occupant classification system. While not a widespread problem, some owners have reported issues with the catalytic converter failing prematurely. Overall, while the QX56 offers a strong foundation, potential buyers should be prepared for maintenance costs associated with these known weaknesses, particularly concerning the transmission and timing chain.
How long will the 2006 Infiniti QX56 last?
With diligent maintenance, the 2006 Infiniti QX56 can achieve well over 200,000 miles. Many owners report reaching this mileage or beyond, testament to its underlying robust construction, particularly its V8 engine. However, long-term durability is heavily influenced by how well the known weaknesses are addressed. The transmission is often the Achilles' heel; if it hasn't been rebuilt or replaced, it can limit the vehicle's lifespan. Similarly, timely replacement of the timing chain components and regular suspension servicing are crucial. Those who prioritize regular oil changes, fluid flushes, and addressing minor issues promptly will likely enjoy many years of service, while neglecting these can lead to costly repairs and a shorter operational life. It excels in its ability to endure; its weaknesses are primarily mechanical components that require attentive care.
What Technology & Safety Features are Included?
The 2006 Infiniti QX56 was well-appointed for its time, offering a solid suite of technology, entertainment, and safety features that appealed to luxury buyers. Standard technology included a premium Bose audio system with an in-dash 6-disc CD changer, power-adjustable heated front seats with memory functions, and tri-zone automatic climate control. A significant tech feature, often standard or part of a package, was the DVD navigation system, which included a rearview camera to aid in parking and maneuvering.
For entertainment, an optional rear-seat entertainment system, typically featuring a flip-down DVD screen and wireless headphones, was available, making it ideal for families on long trips. The QX56 also featured steering wheel-mounted audio controls and cruise control.
In terms of driver-assistance features, the 2006 model was relatively basic by modern standards. It lacked the advanced radar-based cruise control, lane departure warning, or blind-spot monitoring systems common today. However, the standard rearview camera was a notable safety aid.
Safety was a priority, with the QX56 equipped with standard anti-lock brakes (ABS), electronic brakeforce distribution (EBD), brake assist, stability control, and traction control. It also came with front-seat side-impact airbags and roof-mounted side-curtain airbags for all three rows of seating.
Crash-test ratings from the NHTSA showed good performance for its era. The QX56 received 5-star ratings in frontal driver and passenger crash tests and 4-star ratings in side-impact front and rear passenger crash tests. The Insurance Institute for Highway Safety (IIHS) also rated it well in its categories. While it lacks the cutting-edge tech of newer vehicles, its feature set for 2006 was comprehensive and focused on comfort, convenience, and core safety.

When new, the 2006 Infiniti QX56 carried a Manufacturer's Suggested Retail Price (MSRP) typically ranging from around $55,000 to $60,000, depending on optional equipment and drivetrain (RWD vs. AWD). As of late 2023/early 2024, used market prices for the 2006 QX56 vary significantly based on mileage, condition, and maintenance history. Expect to find examples ranging from $4,000 to $9,000 for higher mileage or average condition vehicles, while exceptionally well-maintained examples with lower mileage might fetch closer to $10,000-$12,000.

Final Verdict: Is the 2006 Infiniti QX56 a Good Sport Utility Vehicle?
The 2006 Infiniti QX56 is ideal for buyers seeking a large, luxurious, and powerful SUV with impressive towing capabilities at a significantly reduced price on the used market. It is a great option for families needing ample space and comfort for long journeys. However, it is crucial to buy this vehicle with caution. It is worth buying only if purchased used, and ideally with evidence of a recently replaced or rebuilt transmission, or if you have a substantial budget set aside for potential repairs. Buyers should thoroughly inspect any pre-owned QX56 and be prepared for its substantial fuel consumption and potentially higher maintenance costs compared to less complex vehicles. It is not recommended for those prioritizing absolute reliability or low running costs. Focus on well-maintained examples and consider investing in an extended warranty if possible.
