Specs side by side
What owners say
CTS
Overall
Sentiment is mixed and heavily dependent on generation and specific powertrain. The third-generation CTS (2014-2019) and its high-performance variants (CTS-V, V-Sport) receive significant praise for their handling dynamics, competitive performance, and value proposition when compared to German rivals. The Alpha platform is frequently cited as providing world-class handling, with some owners stating these models handled better than direct competitors.
Best version to buy
Insufficient owner data available to declare a single "best" version. High-performance V-Sport and CTS-V models are highlighted for their engaging driving experience and competitive performance.
Known issues
- ⚠Transmission problems: Includes shuddering, slipping, delayed engagement, and complete failure. Affects the 8-speed automatic (8L45/8L90) in later models and older automatics in earlier models. Very frequent.
- ⚠Cadillac User Experience (CUE) infotainment system failures: Screen delamination, unresponsive touchscreen, phantom touches, and complete failure requiring costly replacement. Very frequent.
- ⚠Electrical system issues: Battery drain problems, faulty sensors, malfunctioning modules (TCM, ECM communication loss), anti-theft system malfunctions, and accessory failures (heated/cooled seats, steering wheel buttons). Very frequent.
XG
Overall
Sentiment is mixed and heavily dependent on the vehicle's age and maintenance history. Long-term owner reports from the early 2000s models (XG300, XG350) describe a vehicle that was smooth, quiet, solid, and offered good value as Hyundai's first foray into the luxury market, with some owners achieving high mileage (e.g., 250,000 miles) with minimal issues. However, a very frequent and dominant theme in community feedback is a pattern of specific, age-related mechanical and electrical failures.
Best version to buy
Insufficient owner data available to designate a specific model year or trim as "best." Feedback spans the 2001-2005 model years (XG300 and XG350) with similar praise for comfort and criticism for electronic issues.
Known issues
- ⚠Electronic throttle body system failure: causes hesitation, unresponsive or erratic acceleration, limp mode (engine speed limited), with diagnostic codes P0224, P1110, P1171, P1195. Frequency: very frequent.
- ⚠Electrical gremlins: malfunctioning interior dome lights, door lights, dashboard illumination, seat warmer lights, door lock actuators, and intermittent tachometer operation. Frequency: recurrent.
- ⚠Engine misfires: particularly cylinder misfires requiring replacement of spark plugs, ignition coils, and wires. Frequency: recurrent.
