The short answer
Based on available data, the Acura TLX comes out ahead of the Subaru Legacy 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
Owners generally regard the TLX as a reliable, comfortable, and well-rounded car, with the 2.4L four-cylinder earning especially strong praise as "bulletproof" and capable of very high mileage with basic maintenance. The V6 is respected for its power and smoothness but is criticized for requiring a timing belt service and, in some cases, being prone to spun bearings. Newer 2021+ models draw complaints about brake rotors, puddle lights, and infotainment/tech glitches, though owners still describe the car as mechanically solid.
Best version to buy
Insufficient owner data available to declare a consensus. The 2.4L four-cylinder receives the most consistent praise for reliability and longevity, while the V6 is favored by owners who prioritize power.
Known issues
Overall
Mixed sentiment with a strong generational divide. Long-term owner reports for older generations (pre-2010) frequently praise the 3.0R and 3.6R flat-six engines for smoothness and potential longevity, with some examples cited as reaching over 200,000 and even 300,000 miles with proper maintenance. The all-wheel-drive system is consistently highlighted as a key strength, providing excellent capability in snow and adverse conditions.
Best version to buy
3.6R models (equipped with the 3.6L flat-six engine) are most frequently recommended by knowledgeable owners. The 3.6R engine is praised for its smooth power delivery and perceived robustness compared to the standard 2.5L four-cylinder, which is often described as underpowered.
