Specs side by side
What owners say
XT5
Overall
Mixed sentiment with a clear generational divide. The vehicle is consistently praised for its comfortable ride, quiet interior, spacious cabin, and perceived value when purchased used at a significant discount from MSRP. Long-term owners express strong satisfaction with the vehicle's practicality and overall driving experience when properly maintained.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. Commentary suggests higher trims (Platinum, Premium Luxury) are sought for their enhanced interior materials and feature content.
Known issues
- ⚠Sudden engine/electrical shutdown while driving: Vehicle loses all power, dashboard lights flash, may engage parking brake; often linked to battery/charging system faults but causes can be elusive. Primarily reported in 2017-2019 models.
- ⚠Outdated/unreliable infotainment system (CUE): Screen freezes, goes black while driving, unresponsive touch controls, Bluetooth/Apple CarPlay connectivity issues causing audio to only play from front speakers at low quality.
- ⚠Transmission problems (2017-2019 models): Shuddering, stuttering, rough shifts; noted to be largely resolved in 2020+ 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).
