What owners say
TLX
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.
