Infiniti QX30: The Complete Deep Dive into Best & Worst Years (2017‑2019)
📖 What is the Infiniti QX30? Full Definition & Origins
The Infiniti QX30 is a subcompact luxury crossover SUV produced from 2016 to 2019 (sold as 2017–2019 model years). It was born from the Renault-Nissan and Daimler partnership, sharing its MFA platform with the Mercedes-Benz GLA-Class. Under the hood sits a 2.0L turbocharged 4-cylinder (208 hp / 258 lb-ft) paired exclusively with a 7-speed dual-clutch automatic transmission (7G-DCT). The QX30 blends European driving dynamics with Infiniti’s design language, offering a raised ride height and available all-wheel drive (AWD).
🔎 Key definition “QX” denotes Infiniti’s crossover/SUV line, and “30” indicates its entry-level compact positioning. Unlike many rivals, the QX30 only had one generation, making year-to-year differences critical for buyers.
🏆 Best & ⚠️ Worst Infiniti QX30 Years: The Definitive Ranking
2019 Infiniti QX30
Why it’s the best: The final model year received revised transmission software that drastically improved low-speed smoothness. It also added Forward Emergency Braking and Rearview Camera as standard across all trims. Complaints about infotainment glitches and sensor faults dropped significantly. Reliability surveys show the 2019 QX30 with the fewest reported issues.
✅ Also excellent: 2018 QX30 – nearly identical mechanical refinement; often better value on the used market.
2017 Infiniti QX30
First-year gremlins: The 2017 QX30 suffers from the most owner complaints. The dual-clutch transmission can be jerky at parking speeds, sometimes hesitating from a stop. Electrical issues include infotainment freezing, random sensor warnings, and battery drain. While many 2017s are trouble-free, the risk is highest here.
🔧 Common 2017 problems: Rough DCT behavior, premature brake wear, turbo wastegate rattle.

🔧 Infiniti QX30 Common Problems & What to Watch For
⚙️ Transmission (7G-DCT)
The dual-clutch transmission is the most discussed component. In 2017 models, it can feel abrupt at low speeds and may hesitate when accelerating from a roll. A software update (available at Infiniti dealers) often improves behavior. Always test drive in stop-and-go traffic.
💻 Infotainment & Electronics
Early QX30s can suffer from screen freezes or Bluetooth disconnects. The system is not compatible with Apple CarPlay or Android Auto in any year. Battery drain issues were reported on some 2017 models due to a faulty telematics module.
🛞 Brakes & Suspension
Premature brake pad and rotor wear (as early as 20k miles) is common. Listen for squealing. The suspension is generally robust, but front strut mounts may develop noise over time.
🌡️ Turbo & Engine
The M274 2.0T engine is reliable if oil changes are kept up. Some owners report wastegate rattle at cold start (normal). Ensure the high-pressure fuel pump recall (if applicable) has been performed.
💰 Maintenance Costs & Schedule
Because of its Mercedes bones, the QX30 has higher maintenance costs than a typical Japanese car. Budget $600–$900 annually. Major services:
- Oil change: Every 10k miles / 1 year (~$120-$180 synthetic).
- Transmission service: 40k miles (~$450-$650).
- Spark plugs: 60k miles (~$350).
- Brake fluid: Every 2 years (~$140).
- Coolant: 100k miles.
