Thinking about buying a used 2017 Infiniti QX60? Or maybe you already own one? Either way, it's smart to be aware of potential issues that this luxury SUV might face. While generally a comfortable and stylish ride, the 2017 QX60 isn't without its quirks, and understanding these can save you time, money, and headaches down the road. Let's dive into the common problems reported by owners, so you can make informed decisions about maintenance and repairs.

Transmission Troubles: The CVT Conundrum

One of the most frequently discussed issues surrounding the 2017 Infiniti QX60 revolves around its Continuously Variable Transmission (CVT). Unlike traditional automatic transmissions with fixed gears, a CVT uses a belt and pulley system to provide a seamless and seemingly infinite range of gear ratios. While this can improve fuel economy and offer a smooth driving experience, it also introduces a set of potential problems.

What's Going Wrong?

  • Shuddering and Hesitation: Many owners report experiencing shuddering, particularly during acceleration or when climbing hills. This feels like the transmission is struggling to find the right "gear," resulting in a jerky and uncomfortable ride. Hesitation is also common, where the vehicle pauses briefly before responding to the accelerator pedal.

  • Transmission Slippage: In more severe cases, the CVT can exhibit slippage, where the engine revs up without a corresponding increase in speed. This is a serious issue that can lead to complete transmission failure.

  • Overheating: CVTs are more susceptible to overheating than traditional transmissions, especially under heavy load conditions like towing or frequent stop-and-go traffic. Overheating can damage the transmission fluid and internal components, leading to premature failure.

  • "Limp Mode": When the CVT detects a serious problem, it may enter "limp mode," which severely restricts engine power and speed. This is a safety feature designed to prevent further damage, but it can be incredibly inconvenient if it happens while you're driving.

Why is This Happening?

The CVT used in the 2017 QX60 (specifically, the JF017E) has a somewhat checkered reputation. Some contributing factors include:

  • Design Limitations: The CVT design itself can be prone to wear and tear over time, especially under demanding driving conditions.

  • Fluid Degradation: CVT fluid is crucial for proper lubrication and cooling. If the fluid isn't changed regularly according to the manufacturer's recommendations (or even more frequently under heavy use), it can degrade and lose its effectiveness, accelerating wear and tear on the transmission.

  • Driving Habits: Aggressive driving, frequent towing, and constant stop-and-go traffic can put extra stress on the CVT, increasing the risk of problems.

What Can You Do About It?

  • Regular CVT Fluid Changes: This is the single most important thing you can do to prolong the life of your CVT. Follow the manufacturer's recommendations for fluid changes, and consider doing it even more frequently if you regularly drive in demanding conditions. Use only the specified CVT fluid to avoid compatibility issues.

  • Gentle Driving: Avoid aggressive acceleration and hard braking, especially when the engine is cold.

  • Avoid Overloading: Be mindful of the vehicle's towing capacity and avoid exceeding it.

  • Monitor for Symptoms: Pay attention to any unusual noises, vibrations, or shifting problems. If you notice any of these symptoms, take your QX60 to a qualified mechanic for inspection as soon as possible.

  • Consider a Transmission Cooler: If you frequently tow or drive in hot climates, installing an aftermarket transmission cooler can help to keep the CVT fluid at a safe temperature.

Electrical Gremlins: When Things Just Don't Work

Beyond the CVT, the 2017 Infiniti QX60 can sometimes suffer from a variety of electrical issues. These can range from minor annoyances to more serious problems that affect the vehicle's functionality.

Common Culprits:

  • Battery Drain: Some owners have reported experiencing premature battery drain, even when the vehicle is not in use. This can be caused by a parasitic draw, where an electrical component is drawing power even when the ignition is off. Potential sources of parasitic draw include faulty sensors, malfunctioning modules, or aftermarket accessories.

  • Infotainment System Issues: The infotainment system in the 2017 QX60 can sometimes be glitchy. Common problems include screen freezes, unresponsive touchscreens, Bluetooth connectivity issues, and navigation errors.

  • Sensor Malfunctions: Modern vehicles rely on a network of sensors to monitor various systems. A faulty sensor can trigger warning lights, affect engine performance, or disable certain features. Common problem areas include oxygen sensors, mass airflow sensors, and wheel speed sensors.

  • Power Window and Door Lock Problems: Some owners have reported issues with power windows and door locks, where they may stop working intermittently or completely. This can be caused by faulty switches, wiring problems, or malfunctioning actuators.

Troubleshooting Tips:

  • Check the Battery: If you're experiencing battery drain, have the battery tested to make sure it's in good condition. Also, check the battery terminals for corrosion and clean them if necessary.

  • Scan for Error Codes: Use an OBD-II scanner to check for any stored error codes. These codes can provide valuable clues about the source of the problem.

  • Check Fuses and Relays: Inspect the fuses and relays related to the affected system. A blown fuse or a faulty relay can often be the cause of electrical problems.

  • Consult a Qualified Technician: Electrical problems can be complex and difficult to diagnose. If you're not comfortable working on electrical systems, it's best to take your QX60 to a qualified mechanic who has experience with Infiniti vehicles.

Interior Annoyances: Cabin Comfort Concerns

While the 2017 Infiniti QX60 boasts a luxurious interior, some owners have reported certain issues that detract from the overall experience.

What Owners Are Complaining About:

  • Seat Leather Wear: The leather upholstery on the seats can be prone to wear and tear, especially on high-use areas like the driver's seat. Cracking, fading, and even tearing can occur over time.

  • Dashboard Cracking: In some cases, the dashboard can develop cracks, particularly in areas exposed to direct sunlight. This is not only unsightly but can also affect the resale value of the vehicle.

  • Sunroof Issues: The sunroof can sometimes experience problems, such as sticking, leaking, or failing to open or close properly. This can be caused by worn-out seals, malfunctioning motors, or debris in the tracks.

  • Third-Row Access: While the third-row seats are a valuable feature for families, accessing them can be a bit cumbersome, especially for adults. The second-row seats don't always slide forward easily, making it difficult to climb into the back.

Addressing the Issues:

  • Leather Care: Regularly clean and condition the leather upholstery to help prevent cracking and fading.

  • Sun Protection: Use a sunshade to protect the dashboard from direct sunlight.

  • Sunroof Maintenance: Periodically clean the sunroof tracks and lubricate the seals to ensure smooth operation.

  • Practice Third-Row Access: Familiarize yourself with the proper procedure for accessing the third-row seats and ensure that passengers are aware of the best way to get in and out.
