When considering the purchase of a 2017 INFINITI Q60, it's important to evaluate the different trims, common issues, diagnostics, and the overall ownership experience on the secondary market. Here’s a comprehensive overview:

Trims Overview

The 2017 INFINITI Q60 is available in three primary trims: Base, Premium, and Red Sport 400.

1. Base Trim

• Features: The base model comes equipped with a turbocharged 2.0-liter four-cylinder engine, a rearview camera, and an 8-inch touchscreen infotainment system.
• Weak Points: Limited performance compared to higher trims, and fewer luxury features. The infotainment system may feel dated to some users.

2. Premium Trim

• Features: This trim includes upgraded interior materials, enhanced audio system, and some advanced safety features.
• Weak Points: Some users report minor electrical issues with the upgraded infotainment and connectivity features. The overall performance is still lower than the Red Sport.

3. Red Sport 400

• Features: This model features a powerful 3.0-liter twin-turbo V6 engine producing 400 hp, sports-tuned suspension, and performance brakes.
• Weak Points: The powerful engine may have a higher risk of overheating, and it can consume more fuel when driven aggressively. Maintenance costs can be higher due to the performance-focused components.

Common Issues Across Trims

Engine

• Common Issues: Potential oil leaks, turbocharger failure, and excessive oil consumption in the Red Sport due to high performance.
• Mileages: Issues typically arise between 60,000 to 80,000 miles.

Transmission

• Common Issues: Transmission fluid leaks and potential failure in adaptive transmission systems.
• Mileages: Problems become evident typically around 50,000 to 70,000 miles.

Suspension

• Common Issues: Worn out bushings and struts leading to a rougher ride.
• Mileages: Problems may develop around 60,000 to 80,000 miles.

Electronics

• Common Issues: Infotainment system glitches, Bluetooth connectivity issues, and sensor failures.
• Mileages: Commonly arise after 40,000 to 60,000 miles.

Diagnostics Required

Tests and Procedures

• Engine Diagnostics: Use an OBD-II scanner to check for trouble codes related to the engine and other major systems. Look for any codes indicating knock sensors, oil pressure, or turbocharger issues.
• Transmission Check: Inspect transmission fluid levels and condition; look for signs of leakage or burnt smell. Test drive to check for smooth shifting.
• Suspension Inspection: Conduct a visual inspection of the undercarriage, looking for signs of leaking shock absorbers or worn bushings. A mechanic should perform a bounce test on the vehicle.
• Electronics Check: Test all infotainment and navigation functions, including Bluetooth connectivity, to identify any glitches.

Systems Requiring Special Attention

• Infotainment and Electrical Systems: Complex integrations can lead to issues, especially as technology evolves.
• Cooling System: Essential for high-performance engines, it is crucial to ensure there are no leaks or blockages.

Ownership Experience on the Secondary Market

Fuel Efficiency

• Base Model: Approximately 24 mpg combined.
• Premium Model: Similar fuel efficiency as the base.
• Red Sport: Slightly lower, around 21 mpg combined due to the larger engine.

Breakdown Frequency

The breakdown frequency can vary significantly depending on maintenance history. In general, Q60s with documented service records tend to have fewer issues. However, owners should anticipate minor electronic glitches and maintenance around the 50,000-mile mark.

Maintenance Costs

• Routine Maintenance: Expect to spend around $600-$1,200 a year on maintenance including oil changes, brake pads, and tire rotations.
• Major Repairs: Should issues arise, particularly with the transmission or engine, costs can skyrocket. Transmissions might cost $3,000-$5,000 to replace, while serious engine work can exceed $6,000.

Long-Term Reliability and Risks

• Long-Term Reliability: To improve overall reliability, keep up with routine maintenance and fluid changes. Specifically, pay attention to the cooling and transmission systems.
• Potential Risks: Look for signs of deferred maintenance. Avoid vehicles that have been heavily modified or abused, particularly the Red Sport variant.

Parts Availability and Cost

• INFINITI parts are generally available in America, but luxury brands may see higher costs compared to mainstream manufacturers.
• Local Mechanic vs Dealership: While local mechanics can service many issues, specialized repairs or parts may require dealership assistance. This could lead to higher costs for both parts and labor if not careful.

In summary, when buying a used 2017 INFINITI Q60, pay attention to the specific trim’s strengths and weaknesses, be proactive in diagnostics, focus on regular maintenance, and be aware of potential long-term costs associated with luxury vehicle ownership. Prioritizing a thorough inspection and maintaining a detailed service history will greatly enhance the ownership experience.
