The 2016 Infiniti QX60, a luxurious three-row SUV, was designed with families in mind, offering a comfortable ride and ample space. However, like any vehicle, it's not without its potential pitfalls. Understanding these common issues can help you make informed decisions, whether you're considering buying one or already own one and want to be prepared for potential repairs. Let's dive into the typical challenges faced by 2016 QX60 owners, so you can keep your ride smooth and your wallet happy.

Is Your CVT Giving You the Blues? The Transmission Troubles

Perhaps the most widely reported issue with the 2016 QX60 is its Continuously Variable Transmission (CVT). Unlike traditional automatic transmissions with fixed gears, a CVT uses a belt and pulleys to provide a seamless range of gear ratios. While this design promises smooth acceleration and improved fuel economy, it can also be prone to problems.

What's the Deal?

  • Shuddering or Hesitation: Owners often describe a shuddering or hesitant feeling during acceleration, especially at lower speeds. This can feel like the car is struggling to find the right gear, even though there are no gears in the conventional sense.
  • Transmission Failure: In more severe cases, the CVT can fail completely, requiring expensive repairs or even replacement. This is obviously the worst-case scenario and can leave you stranded.
  • Whining Noises: A persistent whining noise, especially during acceleration, can be an early warning sign of CVT issues. Don't ignore unusual sounds!
  • Delayed Engagement: Sometimes, there may be a noticeable delay between pressing the accelerator and the car actually moving.

Why Does This Happen?

CVTs are generally more sensitive to fluid degradation than traditional transmissions. Over time, the transmission fluid can break down, losing its lubricating properties and leading to increased wear and tear on the internal components. Heat also plays a role; excessive heat can accelerate fluid degradation and contribute to CVT failure. Some suspect that the factory-specified CVT fluid isn't robust enough for the vehicle's weight and power, especially under demanding driving conditions.

What Can You Do About It?

  • Regular Fluid Changes: This is the single most important thing you can do to prolong the life of your CVT. Follow the manufacturer's recommended service intervals, and consider shortening them if you frequently tow or drive in stop-and-go traffic. Use only the recommended CVT fluid!
  • Avoid Aggressive Driving: Excessive acceleration and hard braking can put extra stress on the CVT. Drive smoothly and avoid sudden changes in speed.
  • Monitor for Symptoms: Be alert for any of the symptoms mentioned above. If you notice anything unusual, take your QX60 to a qualified mechanic for inspection.
  • Consider a Transmission Cooler: If you regularly tow or drive in hot climates, a transmission cooler can help to dissipate heat and extend the life of your CVT.

SMOD Alert! The Dreaded Radiator Issue

Another significant concern for 2016 QX60 owners is the potential for "Strawberry Milkshake of Death" (SMOD), a colorful but terrifying term for coolant mixing with transmission fluid.

The Gist:

The radiator in the QX60 contains separate chambers for engine coolant and transmission fluid. In some cases, these chambers can leak, allowing coolant to mix with the transmission fluid. This creates a pink, milkshake-like substance that circulates through the transmission, causing severe damage.

Why is This So Bad?

Coolant is not designed to lubricate transmission components. When it mixes with transmission fluid, it can cause:

  • Severe Transmission Damage: The abrasive nature of the mixture can quickly wear down the internal components of the CVT.
  • Transmission Failure: In many cases, SMOD leads to complete transmission failure, requiring a costly replacement.
  • Engine Damage: While less common, coolant contamination can also potentially damage the engine.

Spotting the Danger Signs:

  • Pink, Milky Fluid: Check your transmission fluid dipstick (if equipped) for a pink, milky appearance.
  • Coolant Loss: Noticeable coolant loss without any visible leaks can be a sign that coolant is being lost into the transmission.
  • Overheating: Overheating can occur as the cooling system becomes compromised.
  • Transmission Problems: Shuddering, slipping, or other transmission problems can indicate SMOD.

Preventative Measures and Solutions:

  • Regular Inspections: Have your cooling system and transmission fluid inspected regularly by a qualified mechanic.
  • Pressure Test: A pressure test of the cooling system can help to detect leaks before they become a major problem.
  • Bypass the Radiator: Some owners choose to bypass the radiator altogether, using an external transmission cooler instead. This eliminates the risk of SMOD but may require some modifications.
  • Replace the Radiator: If you suspect that your radiator is leaking, replace it immediately.

Tech Gremlins: Electrical and Infotainment Quirks

Modern cars are packed with technology, and the 2016 QX60 is no exception. However, this technology can also be a source of problems.

Common Issues:

  • Infotainment System Freezes: The infotainment system can sometimes freeze or become unresponsive, requiring a reboot.
  • Bluetooth Connectivity Problems: Difficulty pairing devices or maintaining a stable Bluetooth connection is a common complaint.
  • Navigation System Errors: Inaccurate navigation or difficulty updating maps can be frustrating.
  • Sensor Malfunctions: Issues with parking sensors, blind-spot monitoring, or other driver-assistance systems can occur.
  • Battery Drain: Some owners have reported issues with excessive battery drain, especially if the car is left sitting for extended periods.

Troubleshooting Tips:

  • Software Updates: Make sure your infotainment system is running the latest software. Updates often include bug fixes and performance improvements.
  • Reset the System: Try resetting the infotainment system by disconnecting the battery for a few minutes.
  • Check Connections: Inspect the connections to your battery and other electrical components to ensure they are clean and secure.
  • Consult a Technician: If you're unable to resolve the issue yourself, consult a qualified technician who specializes in automotive electronics.

Other Annoyances: Smaller Issues to Watch Out For

While the CVT and radiator issues are the most significant concerns, there are a few other minor problems that 2016 QX60 owners should be aware of.

  • Power Liftgate Problems: The power liftgate can sometimes malfunction, failing to open or close properly. This could be due to a faulty motor, sensor, or switch.
  • Interior Trim Issues: Some owners have reported issues with the interior trim, such as peeling or cracking.
  • Seat Motor Problems: The power seat motors can sometimes fail, making it difficult to adjust the seats.
  • Brake Problems: Some owners have reported premature brake wear or squealing brakes.

Staying Ahead of the Game:

  • Regular Maintenance: Follow the manufacturer's recommended maintenance schedule to keep your QX60 in good condition.
  • Early Detection: Be alert for any unusual noises, smells, or behaviors. Addressing problems early can often prevent them from becoming more serious.
  • Reliable Mechanic: Find a trusted mechanic who is familiar with Infiniti vehicles.

Frequently Asked Questions

  • Is the 2016 Infiniti QX60 reliable? While it offers luxury and space, its reliability is questionable due to CVT and radiator issues. Regular maintenance is crucial.
  • How often should I change the CVT fluid in my 2016 QX60? Follow the manufacturer's recommendation, but consider changing it more frequently (every 30,000 miles) if you tow or drive in harsh conditions. This can significantly extend the life of the transmission.
  • What is SMOD, and how do I prevent it? SMOD is when coolant mixes with transmission fluid due to a radiator leak. Regular inspections and pressure tests can help prevent it.
  • Are there any recalls for the 2016 Infiniti QX60? Check the NHTSA website for any open recalls on your vehicle. Recalls are typically free to address.
