The 2014 Nissan Murano represents a pivotal generation for the crossover, blending modern design with versatile capability. While many owners report satisfaction, understanding common 2014 Murano issues helps you maintain reliability and avoid surprise repairs.
This guide covers the most relevant concerns for 2014 model year owners so you can make informed decisions about care and repairs.
| Issue Category | Typical Symptom | Common Cause | Urgency Level |
|---|---|---|---|
| CVT Transmission | Shuddering, slipping, delayed engagement | Belt wear, low or contaminated fluid, software glitches | Medium to High |
| Engine Performance | Rough idle, hesitation, stalling | Idle air control valve, MAF sensor, vacuum leaks | Medium |
| Electrical & Infotainment | Radio resets, inoperable power windows, sensor faults | Wiring corrosion, blown fuses, module failures | Low to Medium |
| Brakes & Suspension | Squealing brakes, uneven pad wear, loose steering | Worn pads, seized calipers, ball joint wear | High |
| Oil Leaks | Oil spots under parking area, low oil level | degraded valve cover or oil pan gaskets | Medium to High |
CVT Reliability and Performance Concerns
The continuously variable transmission in the 2014 Murano is frequently mentioned in owner forums. Many drivers notice a shudder or hesitation during acceleration, especially in lower gears. Nissan designed this CVT to optimize efficiency and smoothness, but certain wear patterns can undermine that intent.
Regular transmission fluid service using the correct fluid type is critical for extending CVT life. Skipping fluid changes or using incorrect fluids accelerates belt and pulley wear, which can lead to more severe failure. Owners who address early warning signs early often avoid major rebuild costs.
Staying attentive to transmission temperature warnings and avoiding aggressive launch techniques can reduce stress on the belt and variators. When problems escalate, professional diagnostics that include a road test and pressure check help pinpoint whether the issue is fluid related, mechanical, or software based.
Engine and Idle Quality Issues
Some 2014 Murano owners report a rough idle or occasional stalling, particularly when the engine is cold or at stoplights. These symptoms often trace back to the idle air control valve, which can carbon up over time. Cleaning or replacing this valve usually restores stable idle and improves drivability.
The mass airflow sensor (MAF) also plays a key role in air fuel mixture calculations. A dirty or failing MAF can cause hesitation, reduced power, or poor fuel economy. Using quality airflow cleaner during routine maintenance helps keep the sensor reading accurate.
Vacuum leaks from cracked hoses or a loose intake manifold can compound idle problems and trigger stored diagnostic trouble codes. A smoke test or careful visual inspection of vacuum routing identifies small leaks before they affect performance.
Electrical and Infotainment Concerns
Electrical gremlins in the 2014 Murano sometimes appear as random power window failures, radio resets, or warning lights that come on without clear cause. Corrosion at connectors or a weak battery can stress module communication networks. Inspecting harnesses and cleaning terminals often resolves quirky electrical behavior.
The in car infotainment system is another area where owners see glitches, such as unresponsive touchscreens or intermittent audio output. Software updates from the dealer can fix bugs that appear after routine wear. When hardware fails, replacement modules are available, but professional installation ensures proper calibration.
Because many safety and convenience features rely on the same electronic architecture, persistent electrical faults should be diagnosed with a scan tool to read module specific codes. Early attention prevents cascading issues that might affect vehicle security or driver assistance functions.
Brakes, Suspension, and Steering Wear
Brakes on the 2014 Murano can develop squealing or grinding noises when pads are worn unevenly, or when caliper slides stick. Regular inspections help catch uneven pad wear before it damages rotors. Upgrading to higher quality pads and fresh brake fluid can improve modulation and reduce noise.
Suspension components such as ball joints and control arm bushings gradually wear, leading to loose steering feel or uneven tire wear. Drivers who frequently encounter rough road surfaces may see these parts deteriorate faster. Replacing worn bushings and lubricating joints restores predictable handling.
Steering linkage alignment also affects tire longevity and straight line stability. Checking for play in tie rods and ensuring proper wheel alignment after repairs prevents pulling and reduces vibration at highway speeds.
Oil Leaks and Maintenance Points
Oil leaks around the valve cover or oil pan are common in higher mileage 2014 Muranos. Over time, rubber gaskets degrade and may allow oil to drip onto the ground. Catching these leaks early protects engine components and keeps maintenance costs predictable.
Drain plug washers and oil filter seating can also contribute to small leaks if they are not correctly seated during oil changes. Using OEM or high quality aftermarket gaskets reduces the chance of repeat repairs. Following the recommended oil change interval with the proper viscosity extends engine life.
For vehicles that have seen stop and go driving or frequent short trips, more frequent oil changes help dilute contaminants that can accelerate seal wear. Addressing small leaks before they become staining or dripping keeps the undercarriage cleaner and reduces fire risk.
Key Takeaways for 2014 Murano Owners
- Follow the recommended transmission fluid change intervals to protect the CVT.
- Address engine idle concerns early by checking the idle air control valve and MAF sensor.
- Monitor for oil leaks and respond quickly to low oil level warnings.
- Inspect brake pads, caliper slides, and suspension components annually.
- Keep electrical connections clean and update infotainment software when available.
- Use a scan tool or professional diagnostics for persistent warning lights or performance issues.
- Maintain regular service records to track wear patterns and support resale value.
FAQ
Reader questions
Why does my 2014 Murano shake or hesitate when accelerating, especially during merging?
This often points to CVT issues such as belt wear or low/contaminated fluid. A transmission fluid service and road test can reveal slipping or pressure problems that cause hesitation.
What should I do if the infotainment screen keeps resetting or the power windows stop working?
Check fuses first, then inspect wiring and connectors for corrosion. Updating the radio software and verifying module communication can resolve many electrical glitches.
Is a rough idle or stalling at stoplights a sign of a serious engine problem in my 2014 Murano?
Not always; it is commonly caused by the idle air control valve or a dirty MAF sensor. Cleaning or replacing these parts usually restores stable idle without major engine work.
How can I prevent expensive repairs related to suspension and steering wear?
Regular inspections of ball joints, bushings, and tie rods, combined with timely replacements, maintain handling and prevent uneven tire wear or alignment issues.
