The 2018 Infiniti QX30 is a distinctive subcompact luxury crossover, part of Infiniti's brief foray into this segment from 2017-2019. Sharing its platform and powertrain with the Mercedes-Benz GLA-Class, it offers a sophisticated alternative. Available trims include Base, Luxury, Premium, and Sport, with AWD options. New pricing ranged from approximately $30,000 to over $40,000. It stands out for its bold, sculpted styling and upscale interior that feels more premium than its price suggests, appealing to buyers desiring European flair.
The Good
The 2018 QX30 boasts agile performance from its Mercedes-sourced 2.0L turbo engine, offering an engaging driving experience for emotional buyers. Its distinctive, sculpted design and premium interior materials provide a luxurious feel. Practically, it delivers decent fuel efficiency for a luxury crossover and represents excellent used market value, making premium ownership more accessible. Comfort is good with supportive seating.
The Bad
Potential buyers should note the QX30's dated infotainment system lacking Apple CarPlay/Android Auto, and its cramped rear seating and cargo space. Rear visibility is limited. Some may find the ride firm, especially on Sport trims, and the 7-speed dual-clutch transmission can exhibit jerky shifts at low speeds or during downshifts, which is a common complaint.

What Problems Does the 2018 Infiniti QX30 Have?
The 2018 Infiniti QX30, while generally reliable, has several frequently reported problems. A primary concern is the 7-speed dual-clutch transmission (DCT), which, being shared with Mercedes-Benz models, can exhibit rough, jerky, or hesitant shifts, particularly at lower speeds or during downshifts. This behavior can be annoying for owners and, in some cases, lead to premature wear or costly repairs if components fail outside of warranty. Another significant drawback for many is the dated Infiniti InTouch infotainment system. It lacks modern features like Apple CarPlay or Android Auto, and some users report it can be slow to respond or occasionally glitchy, diminishing the overall tech experience.
Interior quality is generally good, but some owners have reported minor creaks or rattles developing over time, especially over rougher pavement. While not widespread, some isolated issues with the HVAC system have also been reported. The firm suspension, while contributing to agile handling, can be a negative for those seeking a more comfortable ride, especially on roads that aren't perfectly smooth.
Regarding recalls, the 2018 QX30 has had very few specific to its model year. One notable recall (NHTSA ID: 18V543000) involved the engine control unit, which could potentially cause the engine to stall under specific conditions for certain 2017-2019 QX30 vehicles. It's always advisable to check a specific vehicle's VIN for any open recalls.
Long-term reliability is considered average for the luxury compact segment. While the Mercedes-Benz derived engine is generally robust, the transmission remains a potential weak point for longevity. Maintenance costs can be higher than non-luxury brands, and out-of-warranty repairs, particularly for complex drivetrain components, can be expensive. Regular, diligent maintenance is crucial for maximizing its lifespan.

Regular, diligent maintenance is crucial for maximizing its lifespan.
How long will the 2018 Infiniti QX30 last?
With diligent maintenance and care, a 2018 Infiniti QX30 can reasonably achieve 150,000 to 200,000 miles, or approximately 10 to 15 years of service. Its Mercedes-Benz sourced engine is generally robust, contributing to decent long-term durability. However, the dual-clutch transmission (DCT) remains a primary long-term concern, with potential for costly repairs as it ages and accumulates mileage. Regular transmission fluid changes, often overlooked, are critical for its longevity.
Other potential weaknesses over time include the infotainment system's eventual obsolescence and the possibility of minor electrical glitches. While interior materials are generally good, some softer plastics may show wear. Suspension components like bushings and shocks will naturally degrade, requiring replacement to maintain ride quality. Overall, attentive maintenance is key to mitigating its inherent weaknesses and ensuring extended service life.

Overall, attentive maintenance is key to mitigating its inherent weaknesses and ensuring extended service life.
What Technology & Safety Features are Included?
The 2018 Infiniti QX30 features a built-in Infiniti InTouch infotainment system, operated via a 7-inch touchscreen, rotary controller, and physical buttons. Standard entertainment includes Bluetooth phone and audio streaming, a USB port, and satellite radio capability. An optional navigation system and a premium Bose 10-speaker audio system significantly enhance the entertainment experience. A notable omission is the lack of Apple CarPlay or Android Auto integration, which was becoming standard on many rivals at this price point.
In terms of driver-assistance, the QX30 comes standard with a rearview camera. Optional features, often bundled in packages, elevate its capabilities: front and rear parking sensors, a helpful Around View Monitor (360-degree camera system), Intelligent Cruise Control (adaptive cruise control), Blind Spot Warning, Forward Emergency Braking, Lane Departure Warning, and Intelligent Park Assist (automatic parallel and perpendicular parking).
Standard safety features include a comprehensive airbag system with 7 airbags (front, side, side curtain, and driver's knee), anti-lock brakes (ABS), traction control, and stability control.
For crash-test ratings, the 2018 Infiniti QX30 did not undergo full testing by the Insurance Institute for Highway Safety (IIHS) or receive an overall safety rating from the National Highway Traffic Safety Administration (NHTSA). However, its structurally similar platform-mate, the Mercedes-Benz GLA-Class, performed well in IIHS tests, generally receiving "Good" ratings in most categories, and "Acceptable" in the Small Overlap Front (driver's side) test, suggesting a reasonable level of occupant protection for the QX30.

2018 Infiniti QX30 Prices and Market Value
When new, the 2018 Infiniti QX30 had an MSRP ranging from approximately $29,950 for the base FWD model to over $45,000 for a fully loaded Premium AWD or Sport trim.
Today, in the used market (late 2023 / early 2024), prices typically range from $12,000 to $20,000, varying significantly by mileage, condition, and trim level.
The QX30 has experienced substantial depreciation. Infiniti vehicles generally depreciate faster than competitors like Audi or BMW, and the QX30's relatively short production run in North America (2017-2019) has further impacted its resale value. Factors affecting resale include high mileage, lack of premium features like navigation or AWD, and its dated infotainment system without modern smartphone integration. The model's discontinuation also makes it less desirable for some buyers seeking longer-term support or a vehicle with consistent market presence.

2018 Infiniti QX30 Cost of Ownership
Owning a 2018 Infiniti QX30 generally entails moderate-to-high long-term costs. Insurance premiums are typically average for a luxury compact crossover. Fuel efficiency is decent, but premium unleaded gasoline is often recommended for optimal performance, increasing fuel expenses. Maintenance costs will be higher than for non-luxury brands, aligning with Infiniti's premium positioning and its shared Mercedes-Benz components. Out-of-warranty repairs, especially for the dual-clutch transmission or complex electronics, can be quite costly due to specialized parts and labor. Therefore, while its used purchase price is appealing, the 2018 QX30 is not an economical vehicle to own in the long run; potential owners should budget accordingly for maintenance and possible repairs.

How Does the 2018 Infiniti QX30 Compare to Other Sport Utility Vehicle?
The 2018 Infiniti QX30 competes in a crowded luxury subcompact crossover segment, facing rivals such as the Mercedes-Benz GLA 250 (its platform mate), Audi Q3, and BMW X1.
Performance: The QX30 excels here, thanks to its potent 208-hp 2.0L turbocharged engine and agile handling, especially the Sport trim. It offers a more engaging drive than the more sedate Audi Q3 and is comparable to the Mercedes-Benz GLA 250. The BMW X1, particularly with its stronger engines, can feel even sportier.
Features: The QX30 boasts a high-quality, distinctive interior and a good array of standard and optional luxury features for its segment.

Alternatives:
- Similar Driving Dynamics & Value: A used Mercedes-Benz GLA 250 (2018-2019) offers almost identical performance and underlying engineering if you prefer the Mercedes badge, though usually at a higher price.
- Better Long-Term Reliability/Resale: Consider a Lexus UX (though it's a newer model and slightly smaller) or even a higher-trim Mazda CX-30, which offers a surprisingly premium feel and modern tech at a non-luxury price point.
- More Modern Tech & Refinement: Newer models of the Audi Q3 or BMW X1 will provide updated infotainment, including Apple CarPlay/Android Auto, and often a more refined driving experience, but at a higher cost.
Final Verdict: Is the 2018 Infiniti QX30 a Good Sport Utility Vehicle?
The 2018 Infiniti QX30 is ideal for buyers seeking a stylish, compact luxury crossover with a distinctive design and premium interior at an attractive used price. It suits individuals or couples who prioritize agile handling and a luxurious cabin over expansive rear passenger or cargo space, or cutting-edge infotainment.
It is definitely worth buying on the used market. Its steep depreciation means it offers excellent value compared to its new price or rivals. For the best experience, target Premium or Sport trims, as they offer enhanced features and driving dynamics. An AWD variant is beneficial for adverse weather.
However, buyers must be prepared for potentially higher maintenance and repair costs due to its luxury branding and shared Mercedes-Benz components, particularly the dual-clutch transmission. A thorough pre-purchase inspection is crucial. Furthermore, be comfortable with its dated infotainment system, as it lacks modern smartphone integration. If these caveats are accepted, the QX30 can be a rewarding and stylish choice.
