Known Problems

A faulty power window switch can cause the power windows to stop working, or to work intermittently.

The 1999-2016 Honda Civic Si engine oil pressure sensor is known to leak from normal operation.

More information about the oil pressure sensor here.

To correct the leak, the sensor must be inspected, properly sealed and installed, or replaced with new.

On certain models the Powertrain Control Module (PCM) can misinterpret the secondary oxygen sensor data and set a false Check Engine Light. A software update from Honda is needed for this issue.

The front brake rotors can warp and cause a vibration when braking. The rotors will need to be machined or in cases where they are worn to thin, replaced to correct this issue.

On certain models the automatic transmission range switch can fail and cause the Check Engine light (MIL) to illuminate, and the engine may not crank intermittently. Replacing the range switch is needed for this repair.
Excessive second clutch wear (automatic transmission) can cause the car not to move and set a Check Engine light (MIL). Replacing the transmission is necessary when this happens.

A fluid leak may develop from one or both front suspension struts. Replacing the struts (usually in pairs) will be necessary to take care of the problem.

On certain models the drivers seat bushings can wear out and the seat can rock back and forth. Replacing the bushings are needed to repair this issue.

On vehicles that have a sunroof, squeaking can occur. Special anti squeak tape should be applied to stop the noise.

Worn door locks (tumblers) can cause the lock not to work. Removing the lock and replacing the worn parts (tumblers) is needed to get the lock working again.

Plugged moon roof drains can cause a water leak inside the car, usually over the head of the driver or passengers head when turning a corner. Cleaning the drains will fix this problem.

Damaged engine mounts can lead to vibration and roughness felt in the steering wheel. A rattle in the dash and engine area may also be heard. Replacement of damaged mounts will commonly correct these issues.

Front compliance bushings may crack and break. Damaged bushing should be replaced before damaged is done to suspension components.
