The short answer
Based on available data, the Lexus NX comes out ahead of the Alfa Romeo Tonale on fuel economy and power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Mixed to negative sentiment overall, with significant concerns regarding reliability, build quality, and value proposition. The vehicle is acknowledged for its sporty driving dynamics, direct steering, and attractive design by some owners. However, these positives are heavily overshadowed by very frequent reports of severe electrical and mechanical issues, including vehicles leaving owners stranded, hybrid system failures, and pervasive software bugs.
Best version to buy
Insufficient owner data available to identify a consensus "best" version. Discussions primarily focus on the model line as a whole rather than trim-level comparisons.
Known issues
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.

The verdict
The Lexus NX is the better choice for most buyers.
It has better fuel economy on its best-equipped version than the Alfa Romeo Tonale, based on the data above. If power matters more to you than running costs, the Alfa Romeo Tonale is worth a closer look instead.
