Specs side by side
What owners say
Q3
Overall
Mixed sentiment with a clear generational divide. Feedback on the second-generation model (2019 onward, often referred to as the F3) is generally positive, with owners praising its comfortable ride, good handling in poor weather, practicality for couples or small families, and the reliable Gen 3 EA888 powertrain. The ability to use regular fuel is frequently cited as a significant positive.
Best version to buy
The 45 TFSI engine (2.0L) is strongly recommended over the smaller 40 TFSI due to adequate power. For trim levels, the Progressiv (Premium Plus in the U.S.) or higher is recommended to avoid overly basic equipment like manual passenger seat adjustments.
Known issues
- ⚠Sunroof leaks – Drains become blocked, causing water ingress into the cabin and headliner. Affects 2019, 2020, and 2021 models specifically. Frequency: recurrent.
- ⚠Excessive road/wind noise – Particularly noticeable at highway speeds, attributed to insufficient sound deadening. Frequency: recurrent.
- ⚠Water pump failure – Faulty component covered by a class action and extended warranty on F3 generation models. Frequency: recurrent.
NX
Overall
Mixed to positive sentiment, heavily dependent on model year and powertrain. The vehicle is widely praised for its exceptional long-term reliability, with the 2015-2021 generation specifically highlighted as "bulletproof." Owners of the post-2022 redesign appreciate the updated technology, smoother ride quality, quieter cabin, and refined interior. However, significant criticism is directed at specific, recurring issues: a very frequent and severe 12V battery drain problem in NX 350h hybrid models, leading to repeated dead batteries; various electrical gremlins and rattles in multiple generations; and a powertrain in earlier turbo models (200t/300) described as underwhelming, with sluggish acceleration and a requirement for premium fuel.
Best version to buy
Insufficient owner data available to declare a single "best" trim or version. Feedback is split by powertrain: the hybrid (350h) is favored for its fuel efficiency and smoothness, but is plagued by battery issues.
Known issues
- ⚠12V Battery Drain (Hybrid Models): Chronic and severe issue causing dead batteries, requiring frequent jumps or trickle chargers, occurs even with regular driving. Owners report multiple roadside assistance calls. Frequency: very frequent.
- ⚠Various Electrical Gremlins: Includes malfunctioning power liftgate (faulty pinch sensors), non-working window switches, delayed key fob response, hands-free microphone failure, "reduced engine power" warnings with no drivability loss, and…
- ⚠Interior Rattles and Build Quality: Rattles from dashboard, center console, infotainment screen, seatbelt area, overhead light, and doors. Loose trim pieces and poorly finished components (e.g., paddle shifter edges).
