The 2021 Infiniti Q50 is a luxury sport sedan, representing Infiniti's commitment to performance and style. As the successor to the highly regarded G37, this generation debuted in 2014, known for its elegant four-door body style. Key trims include Pure, Luxe, Sensory, and the performance-oriented Red Sport 400. Originally priced from approximately $36,000 to $59,000, it stands out for its potent twin-turbo V6 engines and distinctive, aggressive styling, offering a compelling blend of power and luxury appeal.
The Good
The 2021 Infiniti Q50 offers significant advantages, appealing to both heart and head. Its powerful twin-turbo V6 engines, particularly in the Red Sport 400, deliver thrilling performance for emotional buyers. Practically, it provides good value compared to European rivals, a comfortable cabin, and a distinctive, upscale design. Infiniti's reputation for general reliability also adds a layer of practical assurance.
The Bad
Potential buyers of the 2021 Infiniti Q50 should be aware of a few weaknesses. Its dual-screen infotainment system can feel dated and less intuitive than competitors', and the available Direct Adaptive Steering (DAS) often receives criticism for feeling artificial. Some interior materials may also not match the premium feel of its German rivals, and fuel economy can be a concern with the powerful V6 engines.

What Problems Does the 2021 Infiniti Q50 Have?
The 2021 Infiniti Q50, while generally reliable, has some frequently reported problems and potential long-term concerns, along with a couple of notable recalls for its model year.
Common Issues:
- Infotainment System Glitches: Owners frequently report that the dual-screen Infiniti InTouch system can be slow, occasionally freeze, or experience connectivity issues with Bluetooth and smartphone integration (Apple CarPlay/Android Auto). This system's architecture dates back several years, making it less intuitive and responsive than newer competitors' interfaces.
- Direct Adaptive Steering (DAS): For models equipped with DAS (standard on Red Sport 400, optional elsewhere), some drivers criticize its artificial feel or report occasional calibration issues, leading to unpredictable steering responses, though serious failures are less common in later model years.
- Brake Wear: Particularly for the performance-oriented Red Sport 400, the high-performance braking system can experience quicker wear of pads and rotors, leading to more frequent and costly replacements compared to standard models.
- Turbocharger Concerns: While the VR30DDTT engine is robust, like any twin-turbo setup, the turbochargers can be a potential point of failure. Earlier iterations of this engine (2016-2018) saw more reports, but consistent maintenance is key for long-term health in all years.
- Minor Electrical Gremlins: Some owners occasionally report minor electrical issues, such as sensors acting up or interior electronics behaving erratically, though these are typically not widespread or debilitating.
Recalls for 2021 Infiniti Q50:
According to the NHTSA, the 2021 Q50 had a few significant recalls:
- NHTSA Campaign Number 21V068000 (March 2021): Fuel Pump Module: This recall addressed a potential issue where the fuel pump's impeller could deform and interfere with the pump body, leading to a loss of fuel supply and causing the engine to stall while driving. This is a critical safety concern.
- NHTSA Campaign Number 21V190000 (April 2021): Back-Up Camera Display: This recall involved the rearview camera image not displaying properly or at all, which fails to comply with federal safety standards for rear visibility.
Long-Term Reliability:
Overall, the 2021 Q50 is considered to have average to above-average reliability. The VR30DDTT engine is generally robust if properly maintained. However, the complexity of the older infotainment system and features like DAS can be sources of frustration or require attention over a longer ownership period. Regular servicing, especially for performance trims, is crucial to mitigate potential issues and ensure long-term durability.
How long will the 2021 Infiniti Q50 last?
With diligent maintenance and responsible driving habits, a 2021 Infiniti Q50 can reliably achieve an average lifespan of 150,000 to 200,000 miles, translating to approximately 10 to 15 years of service for the typical owner. Its core components, including the VR30DDTT twin-turbo V6 engine and the 7-speed automatic transmission, are generally robust and durable when routinely serviced. The body and chassis also demonstrate good long-term resilience.
However, weaknesses tend to emerge over extended periods. The older infotainment system will inevitably feel more antiquated and may be prone to increasing glitches. Suspension components, particularly on sportier trims or those with Dynamic Digital Suspension, will eventually require replacement due to wear. If equipped, the Direct Adaptive Steering (DAS) system could incur expensive repairs should it fail post-warranty. Additionally, interior materials like leather and soft-touch plastics may show significant wear and tear, and minor electrical components can degrade, leading to various small issues over the vehicle's lifespan.
What Technology & Safety Features are Included?
The 2021 Infiniti Q50 integrates a suite of built-in technology, entertainment, and safety features designed to enhance the driving experience and provide peace of mind. At its core is the Infiniti InTouch dual-screen infotainment system, comprising an 8-inch upper display for navigation and applications, and a 7-inch lower screen for climate and audio controls. This system comes standard with Apple CarPlay and Android Auto integration, alongside Bluetooth connectivity and multiple USB ports. For an elevated audio experience, an optional 16-speaker Bose Performance Series audio system is available, and higher trims often include Infiniti InTouch Navigation and Wi-Fi hotspot capability.
In terms of driver-assistance and safety, the Q50 offers a comprehensive package. Standard features across the lineup include Forward Emergency Braking (FEB) with Pedestrian Detection, Predictive Forward Collision Warning (PFCW), and a basic Rearview Monitor. Moving up the trims or opting for specific packages unlocks a host of advanced systems. These include Blind Spot Warning (BSW) and Blind Spot Intervention (BSI), Lane Departure Warning (LDW) and Lane Departure Prevention (LDP), and Intelligent Cruise Control with full-speed range capabilities. Other notable available features encompass the Around View Monitor with Moving Object Detection (providing a 360-degree camera view), Backup Collision Intervention (BCI) with Rear Cross Traffic Alert, front and rear sonar parking sensors, and advanced lighting such as the Adaptive Front Lighting System (AFS) and High Beam Assist. The highly debated Direct Adaptive Steering (DAS), offering electronic steering without a mechanical link, is also an available or standard feature on certain trims like the Red Sport 400.
For crash-test ratings, the 2021 Infiniti Q50 performed well:
- NHTSA (National Highway Traffic Safety Administration): The Q50 received an impressive 5-star overall safety rating. This included 5 stars for frontal crash, 5 stars for side crash, and 4 stars for rollover resistance.
- IIHS (Insurance Institute for Highway Safety): The IIHS gave the Q50 "Good" ratings in most crashworthiness categories, including moderate overlap front, small overlap front (driver's side), side impact, roof strength, and head restraints & seats. Its front crash prevention system (vehicle-to-vehicle) was rated "Superior," and (vehicle-to-pedestrian) was rated "Advanced." However, headlight ratings varied, with some trims receiving "Acceptable" and others "Poor," which often prevents a "Top Safety Pick" designation.

2021 Infiniti Q50 Prices and Market Value
When new, the 2021 Infiniti Q50 had a Manufacturer's Suggested Retail Price (MSRP) ranging from approximately $36,600 for the base Pure trim to around $55,850-$59,000 for the top-tier Red Sport 400, with Luxe and Sensory trims falling in between. As of late 2023 and early 2024, current used market prices for a 2021 model typically range from $23,000-$27,000 for a Pure, $26,000-$30,000 for a Luxe, $29,000-$33,000 for a Sensory, and $36,000-$42,000 for a Red Sport 400.
Depreciation is a notable factor for the Q50; it generally depreciates faster than its key German and even some Japanese luxury competitors. This significant drop in value makes it an attractive used purchase, but less ideal for original owners concerned with resale. Factors affecting its resale value include the vehicle's overall condition, mileage, trim level (Red Sport 400s hold value better due to performance), specific optional features like AWD, and a comprehensive maintenance history. Broader market trends favoring SUVs and Infiniti's less dominant brand perception in the luxury segment also contribute to its depreciation trajectory.
2021 Infiniti Q50 Cost of Ownership
Owning a 2021 Infiniti Q50 generally places it in the costly to own category, especially compared to non-luxury vehicles. Insurance costs will be higher than average due to its luxury status and performance capabilities, particularly for the Red Sport 400. Fuel expenses are significant; the twin-turbo V6 engines require premium fuel and are not particularly efficient. Routine maintenance, including oil changes and scheduled services, will be more expensive than for a mainstream brand, reflecting luxury parts and labor rates. Repair costs can be substantial if issues arise, especially for complex systems like the infotainment or Direct Adaptive Steering (DAS), or specialized components on the Red Sport 400. While potentially less expensive than some direct German rivals, it's far from economical, requiring a solid budget for long-term ownership.

How Does the 2021 Infiniti Q50 Compare to Other Sedan?
The 2021 Infiniti Q50 competes in a highly competitive luxury sport sedan segment, stacking up against formidable rivals such as the BMW 3 Series (330i/M340i), Mercedes-Benz C-Class (C300/AMG C43), Audi A4/S4, and Lexus IS 350.
In terms of Performance, the Q50 presents a strong case. Its 300-hp V6 models (Pure, Luxe, Sensory) are competitive with the base and mid-tier engines of rivals like the BMW 330i, Mercedes C300, and Audi A4, often offering more standard power. The 400-hp Red Sport 400, however, is the Q50's ace, directly challenging the performance of the BMW M340i, Mercedes-AMG C43, and Audi S4. The Red Sport 400 typically provides comparable or even superior horsepower for a lower price point than its German counterparts, though its handling might not be as dynamically sharp as a BMW.
Regarding Features, the Q50 offers a good array of standard luxury amenities for its price. However, its Achilles' heel is the dual-screen InTouch infotainment system, which feels decidedly dated compared to the slicker, more modern interfaces found in German rivals or even the Lexus IS. While Apple CarPlay and Android Auto are standard, the overall cabin design and material refinement in some areas also fall slightly behind the class leaders, who often offer more advanced digital instrument clusters and higher-quality switchgear.
Reliability is where the Q50 can shine. Infiniti generally holds a reputation for solid reliability, often on par with or slightly better than its German competitors, and often comparable to the highly dependable Lexus IS. While specific issues like the Direct Adaptive Steering (DAS) or infotainment glitches can arise, the core engine and transmission are generally robust. Maintenance costs, however, are still at a luxury level.
The most compelling aspect of the Q50 is often its Price. Both new and on the used market, the 2021 Q50 consistently undercuts its German rivals, offering excellent performance-for-dollar value. It's generally priced similarly to or slightly below the Lexus IS.
Recommended Alternatives:
- For superior driving dynamics and cutting-edge tech (at a higher price): BMW 3 Series (especially M340i), Mercedes-Benz C-Class, Audi S4. These offer a more refined and modern driving experience.
- For exceptional refinement and potentially better long-term reliability (similar price): Lexus IS 350. It provides a luxurious, comfortable ride with a strong reputation for durability.
- For a balanced approach with modern styling and good value: Acura TLX. While not offering the Q50's peak horsepower, it's a well-rounded and attractive alternative.
Final Verdict: Is the 2021 Infiniti Q50 a Good Sedan?
The 2021 Infiniti Q50 is ideal for buyers who prioritize strong performance, particularly its potent twin-turbo V6 engines, and distinctive, aggressive styling without paying the higher premium of its German rivals. It appeals to those seeking a luxury badge and a thrilling drive, even if it means foregoing the absolute latest in interior technology or the most cutting-edge driving dynamics.
The Q50 is certainly worth buying, but primarily as a used vehicle. Its significant depreciation makes it an excellent value proposition in the pre-owned market. For performance enthusiasts, the Red Sport 400 trim is the most compelling choice, offering 400 horsepower for a price considerably lower than its new MSRP. The Luxe and Sensory trims also provide a strong balance of features and comfort for everyday luxury. It's a smart purchase if you value power and bold looks over a state-of-the-art infotainment system or the razor-sharp handling of some competitors, and are prepared for luxury-level fuel and maintenance costs.
