Specs side by side
What owners say
Q5
Overall
Mixed sentiment with a clear dichotomy. The vehicle is consistently praised for its superior driving dynamics, handling, and refinement compared to mainstream and some luxury competitors. Owners frequently describe it as "fun to drive," "super quiet and smooth," and possessing a solid, tank-like build quality.
Best version to buy
The 3.0T supercharged V6 engine (found in pre-2017 Q5 models and in the SQ5) is very frequently recommended over the 2.0T four-cylinder for its power, refinement, and perceived reliability. For newer generations, the plug-in hybrid Q5 e is suggested as a high-feature, powerful, and efficient alternative to the performance-oriented SQ5.
Known issues
- ⚠High maintenance and repair costs: very frequent mentions of routine services costing $1,400-$3,000, with out-of-warranty repairs described as exceptionally expensive. Frequency: very frequent.
- ⚠Electronic/Infotainment glitches: includes CarPlay/Bluetooth connectivity failures, random system reboots, unresponsive screens, and parasitic battery drain causing "Low Battery" warnings in new models (e.g., 2025).
- ⚠Sunroof leaks: noted as a design flaw in some generations (e.g., Q3/Q5), requiring extensive disassembly and often recurring. 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).
