Reviews On 2014 Infiniti Qx60
Welcome, Infiniti QX60 owners! This article is designed to be your go-to resource for common issues and practical solutions for your 2014 QX60. We understand that owning a luxury vehicle comes with the expectation of a smooth and reliable ride, and when things go wrong, it can be frustrating. Let's dive into some frequent problems and how to tackle them.
Common Issues and Solutions for the 2014 Infiniti QX60
1. Transmission Problems: The CVT Conundrum
One of the most frequently reported issues with the 2014 QX60 revolves around its Continuously Variable Transmission (CVT). Symptoms can range from hesitation during acceleration, a whining noise, to more severe issues like slipping or failure. CVTs, while fuel-efficient, can be sensitive and require specific maintenance.
The Problem: The CVT uses a belt and pulley system to provide a seamless range of gear ratios. Over time, the belt can wear, the pulleys can develop issues, or the transmission fluid can degrade, leading to performance problems.
The Solution:
- Regular Fluid Changes: This is crucial. Infiniti recommends a CVT fluid change every 30,000 to 60,000 miles, depending on driving conditions. Use only genuine Infiniti CVT fluid (NS-3) or a compatible equivalent that specifically states it's safe for your transmission. Using the wrong fluid can cause significant damage.
- Fluid Change Procedure: This isn't a simple drain and fill like with traditional automatic transmissions. The QX60 CVT requires a specific procedure to ensure the correct fluid level. It’s best left to a qualified mechanic who knows the procedure.
- DIY Fluid Change (Advanced): If you're experienced with car maintenance, you can tackle this. You'll need:
- Infiniti NS-3 CVT fluid (approximately 5-6 quarts)
- A fluid pump
- A socket set
- A torque wrench
- A drain pan
- A scan tool capable of reading CVT fluid temperature (crucial for proper fill level)
- Professional Diagnosis: If you're experiencing severe symptoms like slipping or failure, a professional diagnosis is necessary. A mechanic can use diagnostic tools to read error codes and pinpoint the problem. It could be a faulty valve body, a worn belt, or other internal damage.
- Transmission Replacement: In the worst-case scenario, the CVT may need to be replaced. This is a costly repair, typically ranging from $4,000 to $6,000, including parts and labor. Consider getting quotes from multiple shops.
Approximate Repair Costs:
- CVT Fluid Change: $200 - $400 (at a shop)
- Valve Body Replacement: $800 - $1,500
- CVT Replacement: $4,000 - $6,000
2. Electrical Issues: Sensors and Beyond
Modern vehicles are heavily reliant on electronics, and the 2014 QX60 is no exception. Electrical problems can manifest in various ways, from malfunctioning sensors to issues with the infotainment system.
The Problem: Common electrical issues include:
- Faulty Oxygen Sensors: Can cause poor fuel economy, rough idling, and a check engine light.
- Battery Drain: Often caused by a parasitic draw, where something is draining power even when the car is off.
- Infotainment System Glitches: Freezing, crashing, or unresponsive touch screen.
- Sensor Malfunctions: Issues with parking sensors, blind spot monitoring, or other safety features.
The Solution:
- Diagnostic Scan: The first step is to get the car scanned for error codes. This will help pinpoint the source of the problem. You can use an OBD-II scanner yourself or take it to a mechanic.
- Oxygen Sensor Replacement: If an oxygen sensor is faulty, it needs to be replaced. This is a relatively straightforward repair, but ensure you use a quality replacement sensor.
- Parasitic Draw Diagnosis: Finding a parasitic draw can be tricky. A mechanic will use a multimeter to test the current draw on different circuits to isolate the source. Potential culprits include aftermarket accessories, faulty relays, or a malfunctioning module.
- Infotainment System Reset: Try a hard reset of the infotainment system. The procedure varies depending on the system version, so consult your owner's manual or search online forums for specific instructions. In some cases, a software update may be necessary.
- Sensor Testing: Use a multimeter to check the voltage and resistance of the sensors in question. Compare your readings to the manufacturer's specifications to determine if they're functioning correctly.
- Check Wiring and Connections: Inspect wiring harnesses and connectors for corrosion, damage, or loose connections. Clean and re-secure any faulty connections.
Approximate Repair Costs:
- Oxygen Sensor Replacement: $150 - $300 (per sensor)
- Parasitic Draw Diagnosis: $100 - $300 (depending on complexity)
- Infotainment System Repair: Varies widely, from software updates ($50-$150) to component replacement ($500-$1500)
3. Suspension Issues: A Bumpy Ride
A comfortable ride is a hallmark of a luxury vehicle, but suspension problems can quickly compromise that. Listen for clunking noises, excessive bouncing, or uneven tire wear.
The Problem: Common suspension issues include:
- Worn Shocks and Struts: Leads to excessive bouncing and poor handling.
- Damaged Control Arms: Can cause clunking noises and instability.
- Worn Ball Joints and Tie Rod Ends: Affects steering and handling.
- Broken Suspension Bushings: Results in clunking noises and imprecise handling.
The Solution:
- Visual Inspection: Inspect the shocks, struts, control arms, ball joints, tie rod ends, and bushings for signs of wear, damage, or leaks.
- Bounce Test: Push down firmly on each corner of the car and release. The car should rebound quickly and settle without excessive bouncing. If it bounces several times, the shocks or struts are likely worn.
- Shock/Strut Replacement: Replacing shocks and struts is a common repair. It's generally recommended to replace them in pairs (front or rear) for balanced performance.
- Control Arm Replacement: If a control arm is damaged, it needs to be replaced. This often requires specialized tools and expertise.
- Ball Joint/Tie Rod End Replacement: Replacing these components requires a ball joint press and other specialized tools. It's crucial to torque the fasteners to the manufacturer's specifications to ensure safety.
- Bushing Replacement: Replacing bushings can be challenging, as they're often pressed into the control arms. A shop press is typically required.
- Wheel Alignment: After any suspension work, a wheel alignment is essential to ensure proper handling and tire wear.
Approximate Repair Costs:
- Shock/Strut Replacement: $300 - $600 (per pair)
- Control Arm Replacement: $300 - $500 (per arm)
- Ball Joint/Tie Rod End Replacement: $200 - $400 (per component)
- Wheel Alignment: $80 - $150
4. Other Common Issues:
Brake Problems: Inspect brake pads and rotors regularly. Listen for squealing or grinding noises. Ensure proper brake fluid levels. Replacement costs vary depending on the extent of the repair.
Air Conditioning Issues: Check the refrigerant level. If the A/C is blowing warm air, there may be a leak or a faulty compressor. Recharge kits are available, but professional service is recommended for accurate diagnosis and repair.
Engine Problems: Address any warning lights promptly. Regular oil changes are crucial. Listen for unusual noises, and monitor fuel economy. A diagnostic scan can help pinpoint the source of engine problems.
Preventative Maintenance: The Key to Longevity
The best way to avoid major problems with your 2014 Infiniti QX60 is to adhere to the recommended maintenance schedule. This includes:
- Regular oil and filter changes
- Transmission fluid changes (CVT)
- Coolant flushes
- Brake fluid flushes
- Air filter and cabin air filter replacements
- Spark plug replacement
- Tire rotations and inspections
By staying on top of preventative maintenance, you can help ensure that your QX60 provides years of reliable service.
Final Thoughts
Owning a 2014 Infiniti QX60 can be a rewarding experience. By understanding the common issues and taking proactive steps to address them, you can keep your vehicle running smoothly and reliably.
