2012 Honda Civic si problems
The Honda Civic Si is a sport compact trim of Honda's Civic. The Si (Sport Injected) trim was introduced for the third generation of Honda Civics in both Japan and North America. In Canada and elsewhere, the trim became known as the SiR for the sixth and seventh generations as the "Si" badge was used for the equivalent to the USDM Civic EX model.
For the Japanese and European markets, the Civic Type R was adopted as the high-performance variant of the Civic, starting with the EK9 hatch for Japan in 1996 and then with the EP3 hatch for Europe in 2001. The 2017 model year marked the first time that the Civic Type R was sold in North America, previous to this the Si trim was the highest in North America (except for Acura vehicles). While the Civic Type R has a more powerful engine, plus it being available in a more track-oriented and spartan configuration including less sound deadening and amenities, by contrast the Civic Si has been positioned as more of a full-featured sport trim, featuring luxury options such as a sunroof and a seven-speaker audio system.
1984–1987
Honda first adopted the Si badge for the Japanese domestic market (JDM) third-generation Civic in November 1984. Japanese and European Si's received a 118 hp (88 kW) DOHC engine, while US and Canadian cars were powered by a 91 hp (68 kW), 12-valve SOHC engine. The Civic Si also appeared in New Zealand and Australia in 1987, with specifications similar to those of the American-market Si.

Common 2012 Honda Civic si problems
Based on the complaints from owners of the Honda Civic Si 2012, several common problems have been identified:
- Oil Dilution: Excess fuel vapors not being burned up in the combustion process can lead to oil dilution in the Civic Si. This issue causes the oil to become thinner, potentially causing leaks and engine damage. Regular tuning and fuel system maintenance are crucial to prevent this problem.
- Direct Injection Carbon Build-Up: The design of the direct-injection engine in the Civic Si can lead to carbon build-up on the tops of the valves over time. This build-up can result in reliability issues, decreased performance, rough idle, and poor throttle response. Solutions like walnut blasting or fuel injection cleaners are recommended to address this issue.
- High Engine Oil Consumption: Some 2012 Civic Si models with a 2.4-liter gasoline engine are prone to high engine oil consumption due to abnormal wear of the engine pistons and piston rings. This issue can lead to increased maintenance needs and potential engine damage.
- Starter Bendix Issues: In some cases, the starter bendix in the Civic Si may spin without making contact with the flywheel teeth when starting the engine. Replacing the faulty starter motor with a new part meeting quality specifications is necessary to correct this problem.
- Electronic Power Steering Module Malfunction: Malfunctions in the electronic power steering module can cause the EPS light to illuminate on the instrument panel and make the steering wheel hard to turn. Addressing this issue promptly is essential for safe driving and proper vehicle operation.
- Air Intake Hose Ripping: Over time, the air intake hose in the Civic Si can develop rips, leading to hard starting conditions, rough idle, and hesitation during acceleration. This issue can impact engine performance and should be addressed to maintain optimal vehicle operation.
- Heater Blower Motor Noise: The heater blower motor in the Civic Si is prone to becoming noisy over time, indicating a need for replacement to restore proper heating and ventilation functions.
- TPMS Sensor Malfunction: TPMS sensors in some Civic Si vehicles are prone to malfunction or premature battery discharge, causing the TPMS light to illuminate on the instrument panel. Ensuring the proper functioning of these sensors is crucial for monitoring tire pressure and vehicle safety.
- Front Wheel Bearing Noise: Front wheel bearings in certain Civic Si vehicles may become noisy between 120,000 and 150,000 miles, necessitating replacement to maintain smooth and quiet operation of the vehicle.
