On automatic-transmission Civics the ATF cooler is integrated inside the radiator's end tank. As the radiator ages the internal cooler wall corrodes/breaches, letting engine coolant and transmission fluid mix. The result is a pink, milky emulsion (a 'strawberry milkshake') visibl… Repairs typically run $400-$3,500. Severity: high.

The 2001-2005 (7th generation) Civic automatic transmission is widely documented as failing prematurely, often before 90,000 miles. Owners report harsh/abrupt shifting, the engine revving without the car moving, slipping, or no engagement in drive — typically from torque-converte… Repairs typically run $1,800-$3,500. Severity: high.
The idle air control valve (IACV) on the throttle body meters the air that bypasses the closed throttle at idle. On D-series Civics it fouls with carbon and the pintle sticks, so the ECU can no longer stabilize idle. Symptoms are a hunting/surging idle, abnormally high idle, or t… Repairs typically run $50-$300. Severity: medium.
P0741 sets when the PCM commands the torque converter clutch (TCC) to lock up but the measured engine-vs-input RPM slip (greater than ~200 RPM) shows it is not engaging (stuck off) or slipping. It applies only to automatic/CVT-transmission Civics. This is a well-known Honda autom… Repairs typically run $150-$2,500. Severity: medium.
On the D17 the EGR passages inside the intake manifold pack with carbon over time. Restricted flow sets P0401 (insufficient EGR flow), while a stuck/dirty valve can set P0402 (excessive flow). Owners chase this because a new EGR valve alone rarely fixes it — the manifold ports th… Repairs typically run $100-$450. Severity: medium.
The clockspring (cable reel) is the coiled ribbon conductor in the steering column that keeps the driver airbag, horn, cruise and steering-wheel controls connected while the wheel turns. Its fine wires fatigue and break, setting a latching SRS code (Honda 10-2, driver's airbag) t… Repairs typically run $100-$350. Severity: medium.
On 7th-gen (and adjacent-era) Civics the heater/AC blower motor resistor (power transistor) and its wiring connector overheat and melt, causing loss of some or all fan speeds, intermittent blower operation, and a burning-plastic smell from the vents. The melted connector commonly… Repairs typically run $30-$250. Severity: low.
The plastic sliders, cable/track and motor of the power window regulators wear out, most often on the driver's door which sees the most cycles. The window slows, moves unevenly, binds off-track, or drops into the door and won't come back up. It is a high-volume search item on bot… Repairs typically run $90-$350. Severity: low.
The VTEC spool valve (solenoid) bolts to the side of the cylinder head and uses oil pressure to actuate variable valve timing. Its rubber sealing gasket hardens and shrinks with age and heat, letting engine oil seep out the side of the head/block. The oil often drips onto the exh… Repairs typically run $20-$150. Severity: low.
The valve cover gasket (and the round spark-plug tube seals) harden and shrink with age on D17 and R18 engines, letting oil weep onto the block and exhaust manifold. Oil dripping onto the hot manifold produces a burning-oil smell and light smoke; oil pooling in the spark-plug wel… Repairs typically run $90-$350. Severity: low.
