2012 Nissan Murano Le Awd Suv

The 2012 Nissan Murano LE AWD SUV represents a compelling blend of comfort, technology, and all-weather capability. As a mid-cycle refresh of the second-generation Murano (Z51 chassis), the 2012 model year brought subtle styling updates and refinements to an already well-received crossover. This article will delve into the key aspects of the 2012 Murano LE AWD, focusing on its mechanical underpinnings, technology features, and overall ownership experience. We'll examine what makes it a worthwhile choice for enthusiasts, a reliable workhorse for mechanics, and a practical option for discerning SUV buyers.

Powertrain and Performance

At the heart of the 2012 Murano LE AWD lies the venerable VQ35DE engine. This 3.5-liter, 24-valve DOHC V6 is a Nissan staple, known for its smooth power delivery and robust reliability. In the Murano, it produces 260 horsepower at 6,000 rpm and 240 lb-ft of torque at 4,400 rpm. This engine configuration prioritizes a broad torque curve, making the Murano feel responsive in everyday driving situations. The VQ35DE utilizes Continuously Variable Valve Timing Control System (CVTCS) to optimize valve timing for improved fuel efficiency and performance across the rev range.

The engine is mated to Nissan's Xtronic CVT (Continuously Variable Transmission). While CVTs often receive mixed reviews from enthusiasts, Nissan has refined its Xtronic technology over the years. The 2012 Murano's CVT offers a simulated gear-stepping function, mimicking the feel of a traditional automatic transmission under hard acceleration. This helps mitigate the droning sound that some CVTs are prone to produce. The CVT also contributes to the Murano's fuel economy, which is EPA-rated at 19 mpg city and 24 mpg highway for the AWD model. For mechanics, understanding the intricacies of the CVT's belt-and-pulley system and its reliance on specialized fluids is crucial for proper diagnosis and maintenance.

The "AWD" designation indicates that this model features Nissan's Intuitive All-Wheel Drive system. This system is primarily front-wheel drive, but it can automatically transfer torque to the rear wheels when it detects wheel slippage or loss of traction. The system uses sensors to monitor wheel speed, throttle position, and steering angle to anticipate the need for all-wheel drive. This on-demand system enhances stability and control in inclement weather conditions, making it a practical choice for drivers in areas with snow or rain. It's important to note that this is not a true off-road system; rather, it's designed to improve on-road traction in slippery conditions.

Chassis and Suspension

The 2012 Murano's chassis is based on Nissan's "D" platform, which it shares with other models like the Altima and Maxima. The suspension consists of independent struts up front and a multi-link setup in the rear. This configuration provides a comfortable ride without sacrificing handling responsiveness. The LE trim level includes 18-inch alloy wheels, which contribute to a more refined appearance and slightly improved handling compared to lower trims with smaller wheels.

The power-assisted rack-and-pinion steering provides decent feedback and requires minimal effort at low speeds. The brake system consists of four-wheel disc brakes with ABS (Anti-lock Braking System), EBD (Electronic Brakeforce Distribution), and Brake Assist. EBD ensures that braking force is distributed optimally between the front and rear wheels to maintain stability during hard braking, while Brake Assist enhances braking power in emergency situations.

Interior and Technology

The 2012 Murano LE stands out for its luxurious interior and comprehensive technology features. Leather upholstery is standard, along with heated front seats, dual-zone automatic climate control, and a power-adjustable driver's seat with memory function. The rear seats offer ample legroom and can recline for added comfort. A power liftgate provides convenient access to the cargo area.

The LE trim boasts an upgraded infotainment system with a 7-inch touchscreen display, navigation, and a Bose premium audio system with 11 speakers. The navigation system is relatively easy to use, although its graphics and processing speed may seem dated by today's standards. Bluetooth connectivity allows for hands-free calling and audio streaming. The LE also includes a rearview camera, which is a valuable aid for parking and maneuvering in tight spaces.

One of the standout features of the LE is the Dual Panel Moonroof. This large glass roof extends over both the front and rear seats, providing an open and airy feel to the cabin. The front section can be opened for ventilation, while the rear section is fixed.

Safety features include standard front and side airbags, as well as side-curtain airbags for both rows of seats. Vehicle Dynamic Control (VDC) with Traction Control System (TCS) helps to prevent skidding and loss of control. The 2012 Murano received good safety ratings from both the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS).

Common Issues and Maintenance

While the 2012 Nissan Murano LE AWD is generally a reliable vehicle, there are a few common issues that owners and mechanics should be aware of:

CVT Problems: As with many vehicles equipped with CVTs, the Murano can experience transmission issues. These can range from minor shuddering to complete transmission failure. Regular CVT fluid changes are crucial to prolong the transmission's life. Nissan recommends using only genuine Nissan CVT fluid to avoid compatibility issues. A thorough inspection of the CVT should be a key part of pre-purchase evaluation.
Timing Chain Tensioner: The VQ35DE engine, while robust, can sometimes suffer from timing chain tensioner issues, particularly in older models. Symptoms include rattling noises from the engine, especially upon startup. Replacing the timing chain tensioner is a relatively involved repair, but addressing it promptly can prevent more serious engine damage.
Oxygen Sensors: Oxygen sensors can fail over time, leading to reduced fuel economy and a check engine light. Replacing faulty oxygen sensors is a relatively straightforward repair.
Wheel Bearings: Premature wheel bearing wear can occur, especially on AWD models. Symptoms include a humming or grinding noise that increases with vehicle speed.
Rust: In regions with heavy salt use during winter, rust can be a concern, particularly on the undercarriage and body panels. Regular washing and waxing can help to prevent rust formation.

Regular maintenance, including oil changes, filter replacements, and tire rotations, is essential to keep the 2012 Murano LE AWD running smoothly. Adhering to the manufacturer's recommended maintenance schedule can help to prevent many of the common issues outlined above.

Real-World Use Case

Consider a scenario where a family living in a snowy climate needs a comfortable and reliable vehicle for daily commutes and weekend trips. The 2012 Murano LE AWD fits the bill perfectly. The all-wheel-drive system provides enhanced traction in snowy and icy conditions, while the spacious interior and comfortable seats make long drives enjoyable. The premium audio system and navigation system keep occupants entertained and informed. The power liftgate simplifies loading and unloading groceries or luggage. Furthermore, with proper maintenance, the VQ35DE engine and Xtronic CVT can provide years of dependable service. The heated seats are a welcome feature during cold winter months, and the moonroof adds a touch of luxury and ambiance to the cabin.

Conclusion

The 2012 Nissan Murano LE AWD SUV offers a compelling package of comfort, technology, and all-weather capability. Its powerful V6 engine, refined CVT transmission, and intuitive all-wheel-drive system provide a smooth and confident driving experience. The luxurious interior and comprehensive technology features make it a comfortable and enjoyable vehicle for both drivers and passengers. While it's essential to be aware of the common issues associated with this model, particularly regarding the CVT, regular maintenance and prompt repairs can ensure years of reliable service. For enthusiasts seeking a practical and refined crossover, for mechanics looking for a familiar and serviceable platform, and for buyers prioritizing comfort and safety, the 2012 Murano LE AWD remains a worthy consideration.
