Infiniti Qx50 Years to AvoidThe weakest years — and the one you should buy instead
After reviewing every Infiniti Qx50 we've analyzed (7 years), these are the 2 weakest. Each one has either an absolute low AutoScore, chronic repair issues, or unusually high ownership costs relative to other Qx50 years.
Proceed with caution
2019 Infiniti Qx50
The 2019 Infiniti QX50 is a sophisticated luxury crossover boasting an innovative VC-Turbo engine, but this technological marvel, coupled with its CVT, introduces a level of long-term risk not present in more traditional powertrains. While offering a premium experience and advanced features, prospective owners must be diligent about maintenance and prepared for potentially expensive repairs should these complex systems falter. It's a calculated risk for those who prioritize innovation and comfort.
Why this year scores low
The revolutionary variable compression engine is complex, with numerous moving parts and specialized sensors. Potential for expensive issues if specific components, like the multi-link crank system or variable valve timing, experience early wear or sensor failures. While specific widespread failures are not yet rampant, the complexity raises future cost concerns.
Infiniti's Continuously Variable Transmission (Jatco variant) can be prone to premature wear of internal belts/pulleys, leading to shuddering, slippage, or complete failure, especially if fluid maintenance is neglected. Software glitches causing hesitation or rough engagement are also reported.
Owners frequently report issues with the dual-screen infotainment system freezing, lagging, or rebooting. Camera glitches, especially the rearview, and various sensor warnings (e.g. parking sensors, ProPilot Assist) can also occur, often requiring software updates or module replacements.
Proceed with caution
2020 Infiniti Qx50
The 2020 Infiniti QX50 offers a compelling package of style, comfort, and advanced technology, but its innovative VC-Turbo engine and continuously variable transmission (CVT) introduce notable long-term reliability considerations. While generally well-built, owners must commit to diligent maintenance to mitigate potential high-cost issues down the road, making it a vehicle for those who understand and are prepared for its specific complexities.
Why this year scores low
The innovative variable compression engine, while powerful and efficient, introduces more moving parts and higher tolerances. Potential for carbon buildup (common in direct injection engines) and long-term wear on the complex variable compression mechanism could lead to expensive repairs if not properly maintained. Early reports indicate some instances of increased oil consumption.
While Infiniti's latest CVTs are improved, the fundamental design remains. Common issues include reduced power delivery, 'rubber band' feel, and in some higher mileage cases, shuddering or complete failure. Proper fluid changes are critical but even then, long-term durability beyond 150,000 miles can be a concern for some owners.
The dual-screen infotainment system, while visually appealing, can be prone to software glitches, freezing, slow response, and occasional connectivity issues (Bluetooth, Apple CarPlay/Android Auto). Less common, but reported, are issues with advanced driver-assistance sensors requiring recalibration or experiencing intermittent faults.
