The 2017 Nissan Murano, while often praised for its stylish design and comfortable ride, hasn't escaped the shadow of transmission troubles. For many owners, the smooth sailing they anticipated has been interrupted by unsettling symptoms, raising concerns about the reliability of the Continuously Variable Transmission (CVT) under the hood. Understanding these issues, their potential causes, and what steps you can take is crucial for any 2017 Murano owner or potential buyer. Let's dive into the specifics of what's been happening and what you can do about it.

Is Your Murano Acting Up? Spotting the Signs of Transmission Trouble

Before we get into the nitty-gritty, it's important to know what to look for. Transmission problems don't always announce themselves with a loud bang. Sometimes, they whisper subtle hints that something's amiss. Recognizing these early warning signs can save you from more significant (and costly) repairs down the road.

Here are some common symptoms reported by 2017 Nissan Murano owners experiencing transmission issues:

  • Shuddering or Hesitation: This is perhaps one of the most frequently reported symptoms. You might feel a shaking or vibrating sensation, particularly during acceleration or when trying to maintain a consistent speed. It can feel like the car is struggling to find the right "gear," even though a CVT doesn't technically have gears in the traditional sense.

  • Slipping: Transmission "slipping" occurs when the engine revs up, but the car doesn't accelerate as it should. It feels like the transmission is struggling to transfer power to the wheels. This can be especially noticeable when climbing hills or carrying a load.

  • Delayed Engagement: When you shift from park to drive or reverse, there might be a noticeable delay before the car actually moves. This delay can be accompanied by a clunking or jerking sound.

  • Unusual Noises: Whining, humming, or clunking noises coming from the transmission area are definite red flags. These noises can indicate internal wear or damage.

  • Erratic Shifting: Even though the Murano uses a CVT designed for smooth transitions, you might experience abrupt or jerky "shifts." The RPMs might fluctuate wildly without a corresponding change in speed.

  • Check Engine Light: The dreaded check engine light can illuminate for a variety of reasons, but it's always worth checking for transmission-related codes. A diagnostic scan can pinpoint the specific problem.

  • Overheating: Transmission fluid overheating is a serious issue that can cause significant damage. You might notice a burning smell or see a transmission fluid leak.

  • Loss of Power: In some cases, a failing transmission can lead to a noticeable loss of power, making it difficult to accelerate or maintain speed.

If you're experiencing any of these symptoms, it's crucial to get your Murano checked out by a qualified mechanic as soon as possible. Ignoring these warning signs can lead to more extensive damage and potentially leave you stranded.

Under the Hood: What's Causing These Transmission Woes?

Now that we've covered the symptoms, let's delve into the potential causes of these transmission problems. While the exact reasons can vary, several common factors contribute to CVT failures in the 2017 Nissan Murano.

  • CVT Design Limitations: CVTs, while offering fuel efficiency and smooth acceleration, have inherent limitations. They rely on a belt or chain running between two pulleys to provide a continuously variable range of gear ratios. This design, while innovative, can be more susceptible to wear and tear than traditional automatic transmissions, especially under demanding driving conditions.

  • Overheating: As mentioned earlier, overheating is a major concern for CVTs. Excessive heat can break down the transmission fluid, reducing its lubricating properties and leading to premature wear of internal components. Towing heavy loads, aggressive driving, and even prolonged idling in hot weather can contribute to overheating.

  • Lack of Maintenance: Neglecting regular transmission fluid changes is a surefire way to shorten the lifespan of your CVT. Over time, the fluid degrades and becomes contaminated with metal particles and debris, reducing its ability to protect the transmission's internal components.

  • Driving Habits: Aggressive driving habits, such as frequent hard acceleration and braking, can put excessive stress on the CVT. This can lead to premature wear and tear of the belt or chain and other internal parts.

  • Manufacturing Defects: While less common, manufacturing defects can also contribute to transmission problems. These defects might not be immediately apparent but can lead to premature failure over time.

  • Software Glitches: Occasionally, software glitches in the transmission control module (TCM) can cause erratic shifting or other performance issues. These glitches can sometimes be resolved with a software update.

Digging Deeper: The CVT and Its Particular Quirks

To truly understand the issues, it's worth taking a closer look at the CVT itself. Unlike traditional automatic transmissions that use gears, CVTs rely on a system of pulleys and a belt or chain. This design allows for a seamless and continuously variable range of gear ratios, which contributes to better fuel economy and smoother acceleration.

However, this unique design also has its drawbacks:

  • Belt or Chain Wear: The belt or chain is a critical component of the CVT, and it's subject to wear and tear over time. Factors like high mileage, aggressive driving, and lack of maintenance can accelerate this wear.

  • Pulley Damage: The pulleys themselves can also be damaged by excessive heat, contamination, or wear. Damaged pulleys can cause slipping, shuddering, and other performance issues.

  • Fluid Sensitivity: CVTs are particularly sensitive to the type and condition of the transmission fluid. Using the wrong type of fluid or neglecting regular fluid changes can significantly reduce the lifespan of the transmission.

  • Complex Control System: The CVT's operation is controlled by a complex electronic system that relies on sensors, actuators, and the TCM. Malfunctions in any of these components can lead to transmission problems.

What Can You Do? Taking Action to Protect Your Murano

So, what can you do to prevent or mitigate transmission problems in your 2017 Nissan Murano? Here are some practical steps you can take:

  • Regular Maintenance: This is the most important thing you can do. Follow the manufacturer's recommended maintenance schedule for transmission fluid changes. Use only the specified type of CVT fluid. Consider shortening the interval between fluid changes if you frequently drive in demanding conditions (e.g., towing, heavy traffic, hot weather).

  • Gentle Driving Habits: Avoid aggressive driving habits, such as frequent hard acceleration and braking. These habits put unnecessary stress on the CVT.

  • Avoid Overloading: Don't exceed the vehicle's recommended towing capacity. Overloading can cause the transmission to overheat and fail prematurely.

  • Monitor for Symptoms: Be vigilant for any signs of transmission problems, such as shuddering, slipping, or unusual noises. Address these issues promptly to prevent further damage.

  • Professional Inspection: Have your transmission inspected by a qualified mechanic at regular intervals, especially if you notice any symptoms.

  • Software Updates: Check with your Nissan dealer for any available software updates for the TCM. These updates can sometimes address software glitches that can cause transmission problems.

  • Consider an Aftermarket Cooler: If you frequently tow or drive in hot weather, consider installing an aftermarket transmission cooler. This can help to keep the transmission fluid at a safe temperature and prevent overheating.
