The short answer
Based on available data, the Acura RLX comes out ahead of the Acura TLX 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 consistently describe the RLX Sport Hybrid as an underrated, reliable, and genuinely enjoyable luxury sedan, praising its smooth power delivery, SH-AWD handling, and strong fuel economy for its size. The most common criticisms are low sales volume leading to parts availability concerns, a small trunk, and polarizing interior controls like the touchscreen HVAC and push-button transmission. Several owners call it their favorite car they have owned, with one reporting 112,000 miles of trouble-free driving and another at 188,000 miles with only routine maintenance.
Best version to buy
The 2018-2020 Sport Hybrid is the consensus best choice, with owners specifically recommending 2018-2020 for improved seats and 2020 for Apple CarPlay. The Sport Hybrid trim is strongly preferred over the non-hybrid PAWS models, with one owner stating to "skip the PAWS models" entirely.
Known issues
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.
