The 2015-2018 Nissan Murano is a popular midsize crossover SUV, prized for its refined design, comfortable interior, and suite of advanced features. However, like any vehicle, the Murano has some common problems that owners and prospective buyers should be aware of. In this comprehensive guide, we’ll delve deeply into the most frequent issues reported by Murano owners, along with key buying tips and ownership costs.
Common Problems with the 2015-2018 Nissan Murano
1. Continuously Variable Transmission (CVT) Problems
Nissan's CVT (Continuously Variable Transmission) technology, found in the Murano, is designed for smooth and efficient driving. However, some owners report issues with CVT reliability, particularly concerning jerking, delayed acceleration, or stalling. Over time, these symptoms can worsen, leading to total transmission failure if not addressed early. The CVT issues are often linked to high fluid temperatures within the transmission, which can cause premature wear on internal components.
Signs and Prevention: If you notice delayed or rough shifting, unusual noises, or sluggish acceleration, these could indicate CVT issues. Regular maintenance is essential—ensure the CVT fluid is replaced per Nissan’s recommended intervals, and consider adding an external cooler to help manage transmission temperatures. For prospective buyers, ask about the vehicle’s transmission service history and, if possible, choose models with fewer miles.
2. Suspension and Strut Issues
The Murano’s suspension system provides a smooth ride, but some owners report problems with struts and other suspension components wearing prematurely. Common symptoms include clunking or rattling sounds, especially when driving over bumps or uneven surfaces. In some cases, worn-out suspension parts can also lead to uneven tire wear and reduced handling stability.
Signs and Prevention: Look for any suspension-related noises during a test drive. If you feel excessive bouncing, rattling, or notice uneven tire wear, this could indicate worn suspension parts. Regular inspection and prompt replacement of struts and bushings can help maintain ride quality, though repair costs can add up if multiple suspension components need replacement.
3. Electrical and Infotainment System Glitches
The Murano's advanced infotainment system offers navigation, Bluetooth, and smartphone integration, but some owners have reported glitches. These include problems with the touchscreen becoming unresponsive, the Bluetooth disconnecting randomly, and occasional system freezes. In some cases, the issue may be resolved with a software update, but persistent problems may require more intensive intervention.
Signs and Prevention: During a test drive, check the infotainment system, navigation, and Bluetooth connectivity. Make sure that the touchscreen is responsive, and test all functions. If the infotainment system is unresponsive or glitchy, ask if the dealership has applied software updates. These issues can be frustrating, but they are generally manageable and sometimes covered under warranty if still active.
4. Faulty Oxygen (O2) Sensors
O2 sensors are essential for monitoring the air-fuel mixture and ensuring optimal fuel economy and emissions. In the 2015-2018 Murano, the O2 sensors have been reported to fail prematurely, often causing the "Check Engine" light to come on. A malfunctioning sensor can affect fuel economy and potentially lead to more severe engine issues if left unchecked.
Signs and Prevention: Watch for the "Check Engine" light coming on, which could indicate an O2 sensor issue. Other signs include reduced fuel efficiency and a rough idle. Replacing faulty O2 sensors promptly is advisable, as a delay can lead to further engine management issues. Testing and replacing these sensors is generally affordable compared to major engine repairs, and doing so can save fuel and prevent additional engine strain.
5. Heater Core and Climate Control System Issues
Some Murano owners have reported issues with the heating and climate control system. A faulty heater core can lead to inconsistent heating or, in more severe cases, a coolant leak. Additionally, blower motors and actuators within the climate control system have been known to malfunction, resulting in an inability to control airflow and temperature effectively.
Signs and Prevention: During inspection, test the heating and cooling functions. If you notice a sweet smell inside the cabin (indicative of a coolant leak), fogging on the windows, or inconsistent heating and cooling, this could indicate heater core issues. Climate control repairs can be costly, so catching any symptoms early is important. Flushing the coolant system and checking for leaks can also prevent more serious heating issues.
6. Excessive Oil Consumption
Some Murano owners have reported high oil consumption rates, which can lead to engine strain if not monitored and addressed. Excessive oil consumption is often a result of worn piston rings or valve seals, and it can lead to reduced engine performance and potential overheating. Regularly monitoring oil levels is essential to catch this problem early.
Signs and Prevention: If you notice the oil level dropping between oil changes, or if the engine sounds noisier than usual, excessive oil consumption may be an issue. Regularly checking and topping off oil levels, and ensuring the vehicle has had consistent oil changes, can help minimize the risk of engine damage. If purchasing a used Murano, inquire about its oil consumption habits and inspect the engine for any leaks.
7. Faulty Liftgate Motor and Hinges
The Murano’s power liftgate, while convenient, has been reported to malfunction in some models. Issues with the liftgate motor and hinges can lead to the liftgate opening or closing improperly, or getting stuck mid-motion. This is typically due to wear on the motor or alignment issues with the hinges over time.
Signs and Prevention: Test the liftgate during your inspection by opening and closing it several times. Listen for any unusual noises or hesitation, and ensure it operates smoothly. Realigning the liftgate or repairing the motor can be a moderate expense, so verifying that it’s in good working order before purchasing can save potential repair costs.
Buying Tips: What to Look for in a 2015-2018 Nissan Murano
