Is the 2017 Infiniti Q50 Worth Buying?

The 2017 Infiniti Q50 offers an engaging driving experience and premium cabin, but its overall reliability is a mixed bag, particularly with the newer 3.0L twin-turbo VR30DDTT engine. While many units run flawlessly, the potential for significant engine and electrical issues means careful pre-purchase inspection and a robust maintenance strategy are paramount to avoid unexpected, costly repairs. Proceed with caution, especially if considering a VR30DDTT model without verifiable service history.

While offering undeniable style and performance, the 2017 Infiniti Q50, especially with the VR30DDTT engine, carries a moderate risk of costly repairs. A thorough pre-purchase inspection, meticulous service history verification, and a healthy repair budget are essential. The Hybrid model offers a more reliable path…

What Tends to Fail First on the 2017 Infiniti Q50

The systems that tend to fail first on the 2017 Infiniti Q50, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.

VR30DDTT Engine (3.0T)major~40,000-80,000 mi

Twin-turbochargers, specifically the wastegate actuators and turbine housings, are prone to premature failure, leading to reduced boost, power loss, and sometimes catastrophic engine damage if not addressed. Intercooler leaks (charge air…

Electrical & Infotainment (InTouch)moderate~20,000-70,000 mi

The dual-screen InTouch system can suffer from freezing, lagging, non-responsiveness, or random reboots. Other electrical gremlins include battery drain issues, failing sensors (e.g., ABS, wheel speed), and intermittent dashboard warnings.

Direct Adaptive Steering (DAS)major~50,000-100,000 mi

The 'steer-by-wire' system, while innovative, can experience software glitches, sensor failures, or even complete system shutdowns, which require dealer intervention and potentially expensive component replacement.

Full repair-cost ranges, fix-before-you-buy notes, and inspection checklists are in the report.

2017 Infiniti Q50 Mileage Danger Zones

The mileage windows when the 2017 Infiniti Q50 most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.

30,000

Low Risk Zone

At this mileage, most vehicles should still be covered under the factory warranty. Focus on scheduled maintenance and address any early electrical glitches or odd engine noises proactively.

60,000

Maintenance Zone

This mileage often marks the end of the bumper-to-bumper warranty. Expect to budget for major scheduled maintenance, and be vigilant for early signs of VR30DDTT turbocharger issues, suspension wear, and continued electrical nuisances.

90,000

Elevated Risk Zone

Past this point, components like the Direct Adaptive Steering, further electrical issues, and potential major engine component failures (if not addressed earlier) become more likely. Consistent maintenance records are critical.

120,000+

High Risk Zone

Entering true high-mileage territory, the risk of significant repairs increases. If the VR30DDTT turbos haven't been replaced, they're a ticking time bomb. Exhaust components, persistent electrical issues, and transmission longevity depe…

2017 Infiniti Q50 Ownership Cost Outlook

What it typically costs to keep the 2017 Infiniti Q50 on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.

Annual Maintenance

$600-900

Moderate Repairs

$800-2,500 occasionally (e.g., intercooler leak, DAS sensor)

How Long Does the 2017 Infiniti Q50 Last?

For 2017 Q50 3.0T models, I would be very wary of units approaching or exceeding 60,000 miles without verifiable turbocharger service or replacement. For Hybrid models, mileage is less of a concern, but regular high-voltage battery checks are prudent for any vehicle over 100,000 miles.
