How Long Do Nissan Muranos Last

The Nissan Murano, a popular crossover SUV, has garnered a reputation for reliability over the years. However, like any vehicle, its longevity depends heavily on several factors, including maintenance, driving habits, and the specific model year. Understanding the lifespan of a Murano involves looking at various components and their potential failure points.

How Long Do Nissan Muranos Typically Last?

Generally, a well-maintained Nissan Murano can last anywhere from 150,000 to 200,000 miles. Some owners have reported exceeding this range with proper care. This translates to roughly 10 to 13 years of service, depending on annual mileage. However, reaching these figures requires proactive maintenance and addressing potential issues promptly. Ignoring warning signs or neglecting scheduled servicing can significantly shorten a Murano's lifespan.

Factors Influencing Murano Lifespan

Several elements play a crucial role in determining how long your Murano will last:

Maintenance Schedule: Adhering to the manufacturer's recommended maintenance schedule is paramount. This includes regular oil changes, fluid flushes (transmission, coolant, brake fluid), filter replacements (air, cabin, fuel), and inspections.
Driving Habits: Aggressive driving, characterized by hard acceleration and braking, puts extra strain on the engine, transmission, and brakes, potentially reducing their lifespan. Consistent highway driving is generally less demanding than stop-and-go city traffic.
Climate and Environment: Extreme temperatures, salty roads (in winter), and dusty conditions can accelerate wear and tear on various components, including the engine, chassis, and suspension.
Model Year: Some model years of the Murano have been known to have specific issues. Researching common problems associated with your particular year can help you anticipate and address potential failures proactively.
Quality of Parts: Using high-quality replacement parts, especially for critical components like the engine, transmission, and braking system, can significantly improve the Murano's longevity.

Key Specs and Main Parts Affecting Longevity

Understanding the critical components influencing a Murano's lifespan is crucial for effective maintenance and troubleshooting. Here's a breakdown:

Engine (VQ35DE / VQ35DD)

The VQ35DE (older models) and VQ35DD (newer models) are Nissan's 3.5L V6 engines. The VQ35DE is known for its reliability, but potential issues include timing chain wear (especially in older models), oil leaks (valve cover gaskets and rear main seal), and potential catalytic converter failure. The VQ35DD, with its direct injection system, may experience carbon buildup on the intake valves over time, potentially affecting performance and fuel economy. Regular oil changes with high-quality synthetic oil are essential for both engines.

Continuously Variable Transmission (CVT)

The CVT is arguably the most critical factor affecting Murano longevity. Nissan's CVTs have had a mixed reputation, with some experiencing premature failures. Proper CVT fluid changes are absolutely critical. Follow Nissan's recommended interval (typically every 30,000 miles under severe driving conditions) and use only genuine Nissan CVT fluid. Overheating is a major killer of CVTs; consider installing an auxiliary CVT cooler if you frequently tow or drive in hot climates. Common CVT failure symptoms include slipping, shuddering, and whining noises.

Suspension and Brakes

The Murano's suspension system, including struts, shocks, control arms, and bushings, is subject to wear and tear over time, especially on rough roads. Replacing worn suspension components is important for maintaining ride quality and handling. Brake pads, rotors, and calipers should be inspected regularly and replaced as needed. Ensure proper brake fluid flushes to prevent corrosion and maintain braking performance.

Electrical System

The electrical system, including the battery, alternator, starter, and wiring harness, can also impact longevity. A weak battery can strain the charging system and lead to premature alternator failure. Regularly check the battery's voltage and condition. Corroded wiring connectors can cause electrical issues and should be cleaned or replaced as needed.

Real-World Use – Basic Troubleshooting Tips

Here are some common issues and basic troubleshooting steps:

Engine Misfires: Could be due to faulty spark plugs, ignition coils, or fuel injectors. Check for diagnostic trouble codes (DTCs) using an OBD-II scanner.
CVT Slipping: Could indicate low CVT fluid, contaminated fluid, or internal transmission damage. Check the fluid level and condition. If the fluid is dark or smells burnt, a fluid change is recommended. If the problem persists, professional diagnosis is necessary.
Suspension Noises: Clunking or squeaking noises from the suspension could indicate worn struts, shocks, or bushings. Inspect the suspension components for damage or wear.
Brake Squealing: Could be due to worn brake pads or glazed rotors. Inspect the brake pads and rotors for wear.

Safety – Highlight Risky Components

Working on certain components of the Murano can be dangerous if not done properly. Here are some areas to exercise caution:

Fuel System: Working on the fuel system requires extreme caution due to the risk of fire. Disconnect the battery and ensure proper ventilation before working on fuel lines or fuel injectors.
Braking System: Bleeding brakes requires proper technique to avoid introducing air into the system. Improperly bled brakes can result in reduced braking performance and increased stopping distances.
High-Voltage Electrical Components (Hybrid Models): If your Murano is a hybrid model, be extremely cautious when working on high-voltage components. Disconnect the high-voltage battery and follow proper safety procedures to avoid electric shock. Always consult a qualified technician when working on hybrid systems.
Suspension Components Under Load: Springs hold a lot of potential energy. Use proper spring compressors when removing or installing struts to avoid serious injury.
