Specs side by side
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.
Known issues
- Timing belt service required on V6 (approximately 100,000 miles or 7-10 years): Frequency: very frequent. Brake rotor warping and juddering, especially on 2021+ models: Frequency: very frequent.
Cadenza
Overall
Sentiment is sharply divided, creating a high-risk, high-reward ownership profile. A significant portion of long-term owner reports praise the Cadenza for its excellent value proposition, offering a comfortable ride, supportive seats for long journeys, and a well-equipped, near-luxury experience at a competitive price. These owners report trouble-free ownership with only routine maintenance, achieving high mileage (over 100,000 miles/161,000 km) without major issues.
Best version to buy
Limited trim (or SXL, likely referencing the same high trim) is mentioned favorably for its high feature content. There is no strong consensus on a model year, though the 2014-2016 generation is the primary subject of discussion.
Known issues
- Catastrophic engine failure (Lambda 3.3L GDI V6): very frequent reports of blown head gaskets, loss of compression, and complete engine replacements, often covered under warranty extensions but causing months of downtime.
- Excessive repair times: warranty repairs, particularly engine replacements, consistently reported to take multiple weeks to several months due to parts availability and dealership service delays. Frequency: very frequent.
- Oil leaks: recurrent issues with valve cover, timing cover, and oil pan gaskets following major engine work. Frequency: recurrent.
