When discussing the long-term ownership experience of the 2009 Nissan Murano, it is impossible to ignore the significant shift in reliability that occurred during this specific model year. As the third generation of the Murano, this year marked the transition from the first generation's relatively simple design to a more complex, feature-rich crossover that incorporated advanced technology and a new continuously variable transmission. While this evolution brought improved performance and a more refined interior, it also introduced a series of 2009 Nissan Murano problems that have become well-documented among enthusiasts and mechanics alike.
CVT Transmission Failures: The Primary Concern
The most prominent and frequently reported issue surrounding the 2009 model year centers on the Continuously Variable Transmission (CVT). Nissan paired the 3.5-liter V6 engine with this specific transmission, a technology that promised smooth acceleration and better fuel economy. However, the unit proved to be underdeveloped for the power output it was handling, leading to premature wear and catastrophic failure modes. Owners often describe symptoms such as a sudden loss of power, accompanied by a high-p whining or grinding noise, before the vehicle limps or refuses to move entirely.
Symptoms and Progression
Unlike a traditional automatic transmission that fails in distinct gears, a failing CVT often presents with vague symptoms that escalate quickly. Drivers might notice a burning smell emanating from the undercarriage, which indicates slipping internal clutches. Furthermore, the transmission might struggle to engage reverse or exhibit a delay when shifting from park to drive. These 2009 Nissan Murano problems are not merely inconvenient; they are safety hazards, as the loss of propulsion can occur unexpectedly while driving.
Electrical System and Infotainment Glitches
Beyond the mechanical stress on the transmission, the 2009 Murano suffers from a higher-than-average incidence of electrical gremlins that plagued early third-generation models. The dashboard and center console host a complex array of electronics, and many owners have reported random malfunctions that disrupt the driving experience. These issues range from minor annoyances to critical system failures that leave the vehicle inoperable.
Random malfunctions of the navigation system, including freezing screens or failure to boot up.
Failure of the power liftgate to open or close, sometimes cutting off access to the rear cargo area entirely.
Intermittent failure of the radio or complete loss of dashboard instrumentation cluster backlights.
Issues with the key fob recognition system, requiring the driver to physically use the key to unlock the doors.
Brake System Weaknesses
Another critical area of concern involves the braking system, specifically the rear disc brakes. Many 2009 models experienced premature wear and inconsistent performance due to design flaws in the caliper or rotor setup. This issue manifests as a high-pitched squeal or grinding noise when applying the brakes, followed by a noticeable decrease in stopping power. Ignoring these 2009 Nissan Murano problems can lead to dangerous situations, particularly in emergency braking scenarios or in regions that experience frequent rainfall.
Cooling System and Overheating Risks
The cooling system configuration on the 2009 Murano also presented challenges that could lead to severe engine damage if left unaddressed. The vehicle relies on a complex network of hoses, clamps, and the radiator itself to manage the heat generated by the V6 engine. Over time, these components can degrade, leading to leaks or a sudden failure of the water pump. When the cooling system fails, the engine temperature spikes rapidly, potentially causing warped cylinder heads or blown head gaskets, which are expensive repairs.
