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.
XTS
Overall
Mixed sentiment with a clear generational divide. Long-term owner reports for the 2013-2015 models describe significant and expensive reliability issues, leading to a reputation for high maintenance costs. Feedback for the 2016+ models, particularly the 2016, is notably more positive, with multiple owners describing them as "bulletproof" and "nearly perfect" up to high mileage, representing a strong value when purchased used.
Best version to buy
2016 Model Year. There is a strong, recurrent consensus that the 2016 model represents a significant improvement in reliability, particularly regarding the infotainment system.

- CUE Infotainment System Failure: Screen delamination, cracking, and touch unresponsiveness. Very frequent in 2013-2015 models; noted as improved but not eliminated in 2016+. Frequency: very frequent.
- Magnetic Ride Control (MRC) Strut/Suspension Failure: Expensive replacement, often needed around 100,000 miles. Causes rough ride and sagging. Frequency: very frequent.
- Timing Chain Issues (3.6L V6): Chain stretch and related problems, often attributed to infrequent oil changes. Frequency: recurrent.
