Quick Summary
The most common 2015 Nissan Murano problems after 100,000 miles include CVT transmission issues, catalytic converter failure, suspension wear, water leaks, brake wear, and aging electrical components. Paying attention to early warning signs and keeping up with routine maintenance can help extend the life of the vehicle. Regular engine performance inspections, transmission service and fluid checks, and suspension and steering wear inspections make it easier to catch developing problems before they become expensive repairs.
Many owners report that 2015 Nissan Murano problems become more noticeable after the odometer passes 100,000 miles. Even a well-maintained SUV can develop age-related wear that affects reliability, comfort, and performance.
Knowing what to watch for helps you plan maintenance and avoid expensive surprises.
Transmission Problems Are the Biggest 2015 Nissan Murano Problems
The continuously variable transmission is the issue most often linked to high-mileage 2015 Murano models. Drivers may notice hesitation, shuddering during acceleration, delayed response, or slipping as internal components wear over time.
Regular maintenance becomes more valuable as mileage climbs, and car manuals make it easier to understand recommended service intervals and inspection points. A transmission service and fluid check can help identify early signs of wear before they develop into more serious damage. Our manual also includes detailed diagnostic information that goes far beyond a general overview.
Catalytic Converter Failure Can Affect Engine Performance
Catalytic converters naturally deteriorate with age, heat, and extended mileage. As efficiency declines, owners may notice gradual changes in engine performance or emissions-related warnings.
Common indicators include:
- Illuminated check engine light
- Slower acceleration
- Reduced fuel economy
- Failed emissions inspections
- Loss of engine performance under heavier loads
Since these symptoms can resemble other engine or emissions issues, evaluating the complete exhaust and engine management system helps identify the actual source of the problem.
Suspension and Steering Components Wear With Age
Suspension parts naturally wear after thousands of miles on rough roads, potholes, and uneven pavement. Owners may notice clunking sounds, vibration, loose steering, or uneven tire wear as control arms, wheel bearings, and shocks begin to age. These symptoms often appear well beyond the 100,000-mile mark.
A suspension and steering wear inspection helps identify worn components before handling becomes unpredictable.
Water Leaks Can Lead to Interior Damage
Some high-mileage Murano models have experienced water intrusion around the sunroof drainage system, door seals, or window weatherstripping.
Signs of moisture entering the cabin may include:
- Damp carpets
- Water stains on interior trim
- Musty odors
- Condensation inside the vehicle
- Electrical accessories behaving inconsistently after rain
If moisture reaches wiring harnesses or electronic modules beneath the interior trim, additional electrical concerns may develop over time.
Brake System Wear Becomes More Noticeable
Brake components naturally wear with age, especially on vehicles driven in heavy traffic. Drivers may experience longer stopping distances, brake pedal vibration, or unusual noises when rotors and pads reach the end of their service life. Regular inspections help identify these problems before braking performance declines further.
Brake system maintenance also includes checking hoses, calipers, and brake fluid condition. A complete inspection offers a better picture of overall stopping performance than replacing worn pads alone.
Electrical Problems Increase Over Time
Electrical issues become more common as wiring, connectors, and electronic modules age. Owners have reported problems involving dashboard warning lights, power accessories, batteries, and other electrical components after years of daily use. Moisture intrusion can also contribute to electrical faults.
Battery terminals and ground connections deserve attention during routine service because corrosion can create intermittent problems.
Watch for Small Problems Before They Grow
Many high-mileage repairs begin with small warning signs that drivers dismiss as normal aging. Strange noises, warning lights, minor fluid leaks, or subtle changes in steering feel can point to developing mechanical problems. Paying attention to these symptoms early often helps reduce repair costs later.
Routine inspections become even more valuable once a Murano passes 100,000 miles. Looking over major systems during regular maintenance helps identify worn parts before they affect reliability or daily driving.
Keeping a High-Mileage Murano on the Road
Reaching 100,000 miles does not automatically mean the end of a 2015 Nissan Murano. Regular engine performance inspection, transmission service and fluid check, plus suspension and steering wear inspection all help identify developing issues before they become major repairs. Owners who stay ahead of routine maintenance often enjoy many additional miles from their SUV.
If you plan to handle maintenance yourself, Nissan Murano manuals offer detailed repair information, wiring diagrams, maintenance schedules, specifications, and troubleshooting guidance for many common systems.
Having the correct reference can make diagnosing problems much more straightforward while helping you work with greater confidence.

FAQs
What is the biggest problem with the 2015 Nissan Murano?
The most frequently reported issue is the continuously variable transmission (CVT). High-mileage vehicles may develop hesitation, shuddering, delayed acceleration, or slipping. Having the transmission inspected when these symptoms first appear may help prevent more extensive repairs.
Is a 2015 Nissan Murano reliable after 100,000 miles?
Many 2015 Murano models continue to perform well beyond 100,000 miles when they receive regular maintenance. Routine inspections, fluid changes, and prompt attention to warning signs help reduce wear and keep major systems working properly.
What maintenance becomes more important after 100,000 miles?
Owners should pay closer attention to engine performance inspections, transmission service and fluid checks, brake inspections, and suspension and steering wear inspections. Monitoring these areas helps identify worn parts before they affect reliability or safety.
Are electrical problems common on high-mileage 2015 Nissan Muranos?
Electrical issues can become more common as the vehicle ages. Battery connections, wiring, electronic modules, and power accessories may develop faults over time, especially if moisture reaches electrical components.
