Reviews Of 2016 Infiniti Qx50
The 2016 Infiniti QX50, while offering a luxurious experience and nimble handling, presents its own set of maintenance and troubleshooting considerations for owners and mechanics alike. This article dives into the common issues, preventive maintenance strategies, and real-world problems encountered with this particular model year.
Maintenance Essentials for the 2016 Infiniti QX50
Regular maintenance is crucial for prolonging the life and performance of any vehicle, and the QX50 is no exception. Sticking to the manufacturer's recommended service intervals is key.
Oil Changes
Problem: Infrequent oil changes lead to sludge buildup, reduced lubrication, and potential engine damage.
Symptoms: Engine knocking, reduced fuel economy, oil light illumination, dark and sludgy oil.
Cause: Neglecting scheduled oil changes or using the wrong type of oil.
Solution: Adhere to the Infiniti's recommended oil change interval (typically every 5,000-7,500 miles with synthetic oil). Use the correct oil viscosity specified in the owner's manual. For example, many modern engines require 0W-20 or 5W-30. Just like a 2015 Honda CR-V needs specific oil for VTEC performance, the QX50 needs the right lubricant to maintain its engine health. Ensure the oil filter is also replaced with each oil change.
Brake System Maintenance
Problem: Worn brake pads and rotors affect braking performance and safety.
Symptoms: Squealing or grinding noises when braking, longer stopping distances, pulsating brake pedal.
Cause: Normal wear and tear, aggressive driving, and corrosion.
Solution: Inspect brake pads and rotors regularly (every 12 months or 12,000 miles). Replace worn components with quality parts. Consider upgrading to ceramic brake pads for reduced brake dust and quieter operation. Brake fluid should be flushed and replaced every two to three years to prevent moisture contamination, which can lead to reduced braking efficiency and corrosion within the brake lines. Think of it like the brake system in a Nissan Altima; neglecting the brakes can compromise safety significantly.
Tire Care
Problem: Uneven tire wear leads to reduced handling, increased road noise, and decreased fuel economy.
Symptoms: Vibrations, pulling to one side, visible uneven wear patterns (e.g., cupping, feathering).
Cause: Improper tire pressure, misaligned suspension, worn suspension components.
Solution: Check tire pressure monthly and inflate to the recommended pressure (found on the driver's side doorjamb). Rotate tires every 6,000-8,000 miles to ensure even wear. A wheel alignment should be performed annually or whenever new tires are installed. Inspect suspension components (ball joints, tie rod ends, control arm bushings) for wear and replace as needed. Similar to a Toyota Camry, proper tire care is essential for safety and fuel efficiency.
Fluid Checks
Problem: Low fluid levels can cause serious mechanical problems.
Symptoms: Difficulty shifting gears (transmission fluid), overheating (coolant), power steering issues (power steering fluid).
Cause: Leaks, evaporation, normal consumption.
Solution: Regularly check and top off all fluid levels, including engine coolant, transmission fluid, power steering fluid, brake fluid, and windshield washer fluid. Inspect for leaks around hoses, seals, and reservoirs. If significant fluid loss is detected, identify and repair the source of the leak. Specific attention should be paid to the transmission fluid, using only the Infiniti-approved fluid to avoid damage. Consider the transmission in a Ford Explorer; using the wrong fluid can lead to premature failure.
Troubleshooting Common 2016 QX50 Issues
Beyond routine maintenance, certain issues are more prevalent in the 2016 QX50. Understanding these can help you diagnose and address problems quickly.
Navigation and Infotainment System Issues
Problem: Freezing, slow response, or complete failure of the navigation and infotainment system.
Symptoms: Unresponsive touchscreen, system reboots, error messages.
Cause: Software glitches, outdated maps, hardware failure.
Solution: Try a system reset. Check for available software updates from Infiniti. If the problem persists, a visit to a qualified technician may be necessary for diagnosis and repair, potentially involving replacement of the infotainment unit. Older systems, much like those in early Tesla models, can suffer from software bugs over time.
Automatic Transmission Problems
Problem: Harsh shifting, slipping gears, or transmission failure.
Symptoms: Jerky acceleration, difficulty shifting, warning lights on the dashboard.
Cause: Low transmission fluid, contaminated transmission fluid, worn internal components.
Solution: Check transmission fluid level and condition. A transmission fluid flush (using the correct Infiniti-approved fluid) may resolve minor issues. If the problems persist, a professional transmission inspection and repair are required. In severe cases, a transmission rebuild or replacement may be necessary. The transmission in the QX50 is a complex piece of machinery, similar to the automatic transmissions found in many luxury vehicles; prompt attention to shifting issues is essential.
Electrical System Glitches
Problem: Battery drain, intermittent electrical issues, malfunctioning sensors.
Symptoms: Difficulty starting, dimming lights, error messages on the dashboard.
Cause: Faulty battery, parasitic draw, corroded connections, defective sensors.
Solution: Test the battery's health and replace if necessary. Inspect the electrical system for parasitic draws (using a multimeter). Clean and tighten battery terminals and ground connections. Scan the vehicle's computer for error codes to identify malfunctioning sensors or components. Electrical problems can be tricky, mirroring issues often seen in BMW models; a systematic approach to diagnosis is crucial.
Suspension Noises
Problem: Clunking or squeaking noises coming from the suspension.
Symptoms: Noises when going over bumps, poor handling, uneven tire wear.
Cause: Worn bushings, ball joints, struts, or shocks.
Solution: Inspect suspension components for wear and damage. Replace worn bushings, ball joints, struts, or shocks. A suspension inspection is recommended annually, especially if you frequently drive on rough roads. Suspension issues are common in SUVs, and the QX50 is no exception; regular inspection and maintenance are key to a comfortable ride.
Real-World Issues and Solutions
Beyond the typical maintenance items, owners have reported specific issues with the 2016 QX50. Understanding these can help prepare you for potential problems.
* Power Steering Issues: Some owners have reported experiencing power steering failures or reduced power assist. This is a safety concern and should be addressed immediately. Possible causes include a faulty power steering pump, low power steering fluid, or a malfunctioning power steering control module. * Sunroof Problems: The sunroof mechanism can sometimes fail, causing it to get stuck or leak. Regular cleaning and lubrication of the sunroof tracks can help prevent this. If the sunroof malfunctions, a professional repair may be necessary. * Heated Seat Malfunctions: Some owners have reported issues with the heated seats not working properly. This could be due to a faulty heating element, a broken wire, or a malfunctioning control module.Keeping Your 2016 Infiniti QX50 in Top Condition
To ensure your 2016 Infiniti QX50 remains reliable and enjoyable to drive, follow these tips:
* Follow the Maintenance Schedule: Adhere to the manufacturer's recommended maintenance schedule for oil changes, fluid flushes, and other services. * Address Issues Promptly: Don't ignore warning signs or unusual noises. Addressing problems early can prevent them from escalating into more serious and expensive repairs. * Use Quality Parts: When replacing parts, use OEM (Original Equipment Manufacturer) or reputable aftermarket parts to ensure quality and reliability. * Find a Trusted Mechanic: Establish a relationship with a qualified mechanic who is familiar with Infiniti vehicles. * Keep it Clean: Regular washing and waxing can help protect the paint and prevent rust. Interior cleaning helps maintain a comfortable and pleasant driving environment. * Monitor Performance: Pay attention to how your car drives and feels. Notice any changes in performance, such as reduced fuel economy, rough idling, or unusual noises. * Regular Inspections: Conduct visual inspections of your car's exterior and interior regularly.
