2012 Honda Civic

The 2012 Honda Civic marked the beginning of the ninth generation of this popular compact car. It was available with a 1.8-liter inline-4 cylinder engine producing 140 horsepower and 128 lb-ft of torque. A natural gas powered version was also available, as well as a Civic Si with a 2.4-liter inline-4. The standard transmission was a 5-speed manual or a 5-speed automatic (depending on the trim). People generally appreciated the Civic’s fuel efficiency, reliability, and affordability. Common complaints focused on the redesigned styling (especially initially), ride quality (some found it harsh), and interior materials.

Summary

The 2012 Honda Civic, while generally reliable, has some common issues to watch out for. The most significant concerns revolve around the 1.8L engine, specifically potential engine block cracking and excessive oil consumption, which can be costly to repair. Transmission issues, particularly with the automatic, also warrant attention. Other problems like suspension wear, electrical glitches, and interior cosmetic issues are less severe but still impact the ownership experience. Potential buyers should thoroughly inspect the vehicle and check its maintenance history, paying close attention to any signs of these common issues.
