Is the Acura 2.4 engine reliable?

The Acura 2.4L engine, based on the Honda K24 series, is considered highly reliable, with many owners reporting high mileage with minimal issues, say Reddit and Facebook users. Potential issues include timing chain tensioner problems, oil consumption (more so in later K24Z versions), and, less commonly, cracked engine blocks in early K24A versions. Another point to consider is that some models with this engine, like the TLX, are paired with a dual-clutch transmission (DCT) which may require specific maintenance or updates, notes YouTube. 
Reliability and common issues

• Maintenance is key: As with any engine, regular maintenance is crucial to achieve its long lifespan. Owners mention that proper care is essential to get the most out of the engine. 
• Potential issues:
  • Timing chain tensioner: Some K24 engines have documented issues with the timing chain tensioner. 
  • Oil consumption: Oil consumption can be a problem, especially in some of the later K24Z versions. 
  • Cracked blocks: Early K24A engine blocks have been known to crack, though this is less common. 
• Model-specific considerations:
  • Acura TLX: The 2.4L engine in the TLX is paired with a dual-clutch transmission. While the engine itself is reliable, the transmission may require maintenance. Some owners suggest issues can be mitigated by ensuring the car is properly warmed up or by getting software updates, say YouTube and Facebook users. 
  • Acura TSX: While the engine is reliable, some early TSX models (2004-2006, 2009) may have had issues with the engine, transmission, and brakes, recommend CarParts.com. 
• Long-term ownership: The overall reliability is strong, with many owners keeping their cars well over 100,000 miles without major issues, according to Yahoo! Autos.
