The 2009 Nissan Murano, while a stylish and generally comfortable crossover SUV, is unfortunately known for a rather significant Achilles' heel: its Continuously Variable Transmission (CVT). If you own a 2009 Murano, or are considering buying one, understanding the potential transmission issues is absolutely crucial. Knowing what to look for, how to potentially mitigate problems, and what your options are if things go south can save you a lot of headaches and money down the road. Let's dive deep into what makes the 2009 Murano's CVT a point of concern.

So, What's the Deal with the 2009 Murano's CVT?

The 2009 Murano uses a CVT, a type of automatic transmission that provides seamless gear changes and theoretically better fuel economy than traditional automatics. However, the CVT used in the 2009 Murano, manufactured by Jatco (a Nissan subsidiary), has a reputation for unreliability. The main issue boils down to the CVT's design and the stresses it endures. Unlike a traditional automatic with fixed gears, a CVT uses a belt or chain running between two pulleys to create a virtually infinite number of gear ratios. This constant adjustment, combined with the heat generated, can lead to premature wear and failure, particularly in the 2009 Murano.

Uh Oh, What are the Symptoms of a Failing CVT?

Knowing the warning signs of CVT trouble is the first step in preventing a complete breakdown. Here are some common symptoms to watch out for in your 2009 Murano:

  • Slipping or Hesitation: This is a common indicator. You might notice the engine revving high without a corresponding increase in speed, especially when accelerating from a stop or trying to pass someone. It feels like the transmission is struggling to find the right "gear."

  • Jerky or Erratic Shifting: While CVTs are designed for smooth transitions, a failing one might exhibit jerky or uneven acceleration. This can feel like the car is "lurching" forward.

  • Whining or Humming Noises: A failing CVT often emits unusual noises, particularly a whining or humming sound that increases with vehicle speed. This is often caused by worn bearings or other internal components.

  • Overheating: CVTs are sensitive to heat. If your Murano's transmission is overheating, you might see a warning light on the dashboard or experience performance issues.

  • Shuddering or Vibrating: Some owners have reported a shuddering or vibrating sensation, especially at lower speeds. This can be a sign of internal wear or damage.

  • Trouble Codes: A check engine light is never a good sign. Using an OBD-II scanner can reveal transmission-specific trouble codes, such as P0746 (Pressure Control Solenoid Performance or Stuck Off), P0776 (Pressure Control Solenoid B Performance or Stuck Off), or P1778 (Step Motor Function). These codes point to specific issues within the CVT.

  • Complete Transmission Failure: In the worst-case scenario, the CVT can fail completely, leaving you stranded. This is often preceded by a significant increase in the severity of the symptoms listed above.

Why is the 2009 Murano's CVT So Prone to Problems?

Several factors contribute to the higher-than-average failure rate of the 2009 Murano's CVT:

  • Design Limitations: The Jatco CVT used in the 2009 Murano was simply not as robust as it needed to be for the vehicle's weight and engine output. The internal components, particularly the belt or chain, weren't always up to the task.

  • Heat Buildup: CVTs generate a significant amount of heat, and the 2009 Murano's transmission cooling system may not have been adequate to dissipate that heat effectively, especially under demanding driving conditions. Overheating accelerates wear and tear on the CVT.

  • Lack of Maintenance: Many owners were unaware of the specific maintenance requirements for CVTs, such as the need for regular fluid changes using the correct Nissan CVT fluid. Neglecting this maintenance significantly shortens the CVT's lifespan.

  • Driving Habits: Aggressive driving, such as frequent hard acceleration and towing heavy loads, puts extra stress on the CVT and can contribute to premature failure.

What Can You Do to Prevent CVT Problems?

While you can't completely eliminate the risk of CVT failure, there are several steps you can take to prolong the life of your 2009 Murano's transmission:

  • Regular CVT Fluid Changes: This is the most important preventative measure. Use only Nissan NS-2 or NS-3 CVT fluid (check your owner's manual to be sure). The recommended interval is typically every 30,000 miles, but consider more frequent changes if you do a lot of stop-and-go driving or towing.

  • Install an Auxiliary Transmission Cooler: Adding an aftermarket transmission cooler can help dissipate heat and reduce stress on the CVT, especially if you live in a hot climate or frequently tow.

  • Drive Conservatively: Avoid aggressive acceleration and excessive speed. Smooth, gentle driving habits will help reduce stress on the CVT.

  • Avoid Towing: The 2009 Murano is not ideally suited for towing, especially with its CVT. If you must tow, keep the load light and drive cautiously.

  • Monitor Transmission Temperature: Consider installing a transmission temperature gauge to monitor the CVT's temperature. This can give you an early warning of potential overheating issues.

  • Listen for Unusual Noises: Pay close attention to any unusual noises coming from the transmission. If you hear whining, humming, or other strange sounds, have it checked by a qualified mechanic as soon as possible.

  • Check for Leaks: Regularly inspect the transmission for leaks. Leaking fluid can lead to low fluid levels and transmission damage.

Okay, My CVT is Failing. What Are My Options?

If your 2009 Murano's CVT is showing signs of failure, you have several options:

  • CVT Fluid Change: If the symptoms are mild, a CVT fluid change might temporarily improve the situation. However, this is often just a short-term fix. If there is significant internal damage, a fluid change won't solve the problem.

  • CVT Repair: In some cases, it may be possible to repair the CVT. This typically involves replacing worn or damaged components. However, CVT repairs can be complex and expensive, and the results are not always guaranteed. It is also difficult to find shops that specialize in CVT repairs.

  • CVT Replacement: The most common solution is to replace the CVT with a new or remanufactured unit. This is the most expensive option, but it provides the most reliable long-term solution.

  • Used CVT: A used CVT is the least expensive option, but it comes with significant risks. You don't know the history of the used transmission, and it could fail shortly after installation.

  • Sell the Vehicle: If the cost of repairing or replacing the CVT is too high, you might consider selling the vehicle. Be honest with potential buyers about the transmission issues.

Where to Get Your CVT Serviced or Replaced?

Finding a qualified mechanic to service or replace your 2009 Murano's CVT is crucial. Here are some options:

  • Nissan Dealership: A Nissan dealership will have the most experience with Nissan CVTs. However, dealership service can be expensive.

  • Independent Repair Shops: Many independent repair shops specialize in transmission service. Look for a shop with experience working on CVTs.

  • Transmission Specialists: Some shops specialize exclusively in transmission repair and replacement. These shops often have the most expertise and specialized equipment.

Before choosing a shop, get multiple quotes and ask about their experience with CVTs. Make sure they use the correct Nissan CVT fluid and offer a warranty on their work.

How Much Will This Cost Me?

The cost of repairing or replacing a 2009 Murano's CVT can vary depending on the severity of the problem, the location of the repair shop, and the type of replacement unit used. Here's a general estimate:

  • CVT Fluid Change: $150 - $300

  • CVT Repair: $500 - $2000 (depending on the extent of the damage)

  • Remanufactured CVT Replacement (installed): $3,000 - $5,000

  • New CVT Replacement (installed): $4,000 - $6,000+

  • Used CVT Replacement (installed): $1,500 - $3,000 (buyer beware!)

It's always a good idea to get multiple quotes before making a decision.

Frequently Asked Questions

  • What kind of fluid does my 2009 Murano CVT need? Only use Nissan NS-2 or NS-3 CVT fluid. Using the wrong fluid can damage the transmission.
  • How often should I change my CVT fluid? Every 30,000 miles is generally recommended, but consider more frequent changes if you do a lot of stop-and-go driving.
