The short answer
Based on available data, the Chevrolet Trailblazer comes out ahead of the Chevrolet Trax on 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
Sentiment is mixed and varies significantly by generation. For the older GMT360 platform (circa 2002-2009), long-term owner reports describe a vehicle that is "a bit thirsty" and prone to numerous small, persistent electrical and component failures, though the straight-six engine is noted for its reliability. The interior quality is widely criticized as "craptastic." For the newer, unibody generation (2021+), direct owner feedback on driving experience is absent from the provided data.
Best version to buy
Insufficient owner data available. No specific trim or powertrain recommendations are made within the community feedback provided.
Known issues
Overall
Sentiment is sharply divided by generation. For the first-generation models (approximately 2014-2022), owner feedback is overwhelmingly negative, characterized by very frequent and severe mechanical failures leading to high repair costs and widespread distrust. Common catastrophic issues include turbocharger failures, timing chain problems, and complete engine failures, often occurring before 100,000 miles.
Best version to buy
Insufficient owner data available to identify a "best" version. For the new generation, an owner notes the LT trim offers a good balance of features.
