The Nissan Murano: a stylish crossover SUV that promised a blend of comfort, performance, and a touch of luxury. But beneath that sleek exterior lies a question that haunts many potential buyers: how reliable is the Murano, especially when it comes to its transmission? The answer, unfortunately, isn’t always straightforward, and the Murano’s transmission reliability has been a point of concern for many owners, making it crucial to understand the issues and how they might affect your ownership experience.
Murano's Transmission Woes: What's the Real Story?
For many years, Nissan has heavily relied on Continuously Variable Transmissions (CVTs) in their vehicles, including the Murano. While CVTs offer benefits like improved fuel economy and smooth acceleration, they've also been a source of frustration due to reliability issues. The Murano, in particular, has seen its fair share of transmission-related complaints.
So, what's the problem? CVTs, in essence, use a belt and pulley system to provide a seemingly infinite number of gear ratios. This design, while innovative, can be more susceptible to wear and tear compared to traditional automatic transmissions, especially under demanding driving conditions.
Here's a breakdown of common transmission problems reported by Murano owners:
- Shuddering and Hesitation: This is perhaps the most frequently reported issue. Owners often describe a shaking or vibrating sensation during acceleration, particularly at lower speeds. This can feel like the transmission 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 vehicle doesn't accelerate as expected. This can be dangerous, especially when merging onto a highway or attempting to pass another vehicle.
- Overheating: CVTs can generate significant heat, and if the cooling system isn't functioning properly, the transmission can overheat. This can lead to reduced performance, damage to internal components, and eventually, transmission failure.
- Complete Failure: In the worst-case scenario, the transmission can fail completely, rendering the vehicle undrivable. This is obviously the most expensive and inconvenient outcome.
- Delayed Engagement: This refers to a noticeable delay between shifting into drive or reverse and the vehicle actually moving. This can be particularly problematic in tight parking situations.
Which Murano Years are Most Affected?
While transmission problems have been reported across multiple Murano model years, some are more prone to issues than others. Generally, models from 2003 to 2010 and some in the 2013-2018 range seem to have a higher incidence of transmission failures. It's important to note that this doesn't mean every Murano from these years will experience problems, but the risk is statistically higher.
Why Are Murano Transmissions Failing? Digging Deeper
Several factors contribute to the transmission woes plaguing some Nissan Muranos. Understanding these factors can help you make informed decisions about purchasing and maintaining your vehicle.
- CVT Design Limitations: As mentioned earlier, the CVT design itself can be more susceptible to wear and tear than traditional transmissions. The belt and pulley system relies on friction to transfer power, and over time, this friction can cause the belt to slip or the pulleys to wear down.
- Inadequate Cooling: Proper cooling is crucial for CVT longevity. If the transmission fluid overheats, it can lose its lubricating properties and accelerate wear on internal components. Some Murano models may have had inadequate cooling systems, particularly in hot climates or under heavy towing conditions.
- Infrequent Fluid Changes: Transmission fluid plays a vital role in lubricating and cooling the transmission. Neglecting regular fluid changes can lead to a buildup of contaminants and a degradation of the fluid's performance, ultimately contributing to transmission problems. Nissan recommends specific fluid change intervals for their CVTs, and it's crucial to adhere to these recommendations.
- Driving Habits: Aggressive driving habits, such as frequent hard acceleration and abrupt braking, can put excessive stress on the transmission and accelerate wear.
- Manufacturing Defects: In some cases, manufacturing defects may have contributed to transmission failures. While not all failures are due to defects, it's a possibility that can't be ruled out.
- Software Glitches: Some owners have reported that software glitches in the transmission control module (TCM) can cause erratic shifting behavior and potentially contribute to premature wear. Updates to the TCM software can sometimes resolve these issues.
What Can You Do About It? Proactive Steps for Murano Owners
While the transmission reliability of the Murano can be a concern, there are steps you can take to mitigate the risk and potentially extend the life of your transmission.
- Regular Transmission Fluid Changes: This is arguably the most important thing you can do. Follow Nissan's recommended fluid change intervals, and consider changing the fluid more frequently if you frequently drive in stop-and-go traffic or tow heavy loads. Use only the Nissan-specified CVT fluid, as using the wrong fluid can damage the transmission.
- Avoid Aggressive Driving: Drive smoothly and avoid hard acceleration and abrupt braking. Treat your Murano with respect, and it's transmission will likely thank you for it.
- Check for Leaks: Regularly inspect the transmission for any signs of leaks. Leaks can lead to low fluid levels, which can cause overheating and damage to internal components.
- Monitor Transmission Temperature: If you frequently tow or drive in hot climates, consider installing a transmission temperature gauge to monitor the temperature. If the temperature gets too high, pull over and let the transmission cool down.
- Consider an Auxiliary Transmission Cooler: If you frequently tow or drive in hot climates, an auxiliary transmission cooler can help keep the transmission temperature down and extend its life.
- Listen for Unusual Noises: Pay attention to any unusual noises coming from the transmission, such as whining, clunking, or grinding. If you hear anything suspicious, have the transmission inspected by a qualified mechanic.
- Software Updates: Check with your Nissan dealer to see if there are any software updates available for your transmission control module (TCM). These updates can sometimes improve shifting performance and prevent problems.
- Pre-Purchase Inspection: If you're considering buying a used Murano, have a qualified mechanic perform a thorough pre-purchase inspection, including a transmission inspection. This can help you identify any potential problems before you buy the vehicle.
The Cost of Transmission Trouble: What to Expect
Unfortunately, transmission repairs or replacements can be expensive. The cost will vary depending on the severity of the problem, the model year of your Murano, and the labor rates in your area.
- Minor Repairs: Minor repairs, such as fluid leaks or software updates, may cost a few hundred dollars.
- Major Repairs: Major repairs, such as replacing internal components, can cost several thousand dollars.
- Transmission Replacement: Replacing the entire transmission is the most expensive option, and can easily cost upwards of ,000 to ,000, depending on whether you opt for a new, rebuilt, or used transmission.
It's always a good idea to get multiple quotes from different repair shops before authorizing any work.
Beyond the Transmission: Other Reliability Considerations
While the transmission is a major concern, it's important to remember that the Murano, like any vehicle, has other potential reliability issues. Some common problems reported by Murano owners include:
- Electrical Issues: Problems with the electrical system, such as faulty sensors, malfunctioning power windows, and issues with the infotainment system.
- Suspension Problems: Premature wear of suspension components, such as struts and bushings.
- Brake Problems: Issues with the brakes, such as premature wear of brake pads and rotors.
- Engine Problems: While less common than transmission issues, some Murano owners have reported engine problems, such as oil leaks and issues with the timing chain.
