What is the 2001-2011 Honda Civic Radiator Internal Transmission-Cooler Failure — ATF/Coolant Cross-Contamination ('Strawberry Milkshake')?
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.
What is the 2001-2005 Honda Civic 7th-Gen Automatic Transmission Failure — Slipping, No Engagement, and Premature Failure?
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.
What is the 2001-2011 Honda Civic SRS Clockspring / Cable-Reel Failure — Airbag Light, Dead Horn and Cruise?
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.
What is the 2001-2005 Honda Civic EGR Port Carbon Clogging — P0401/P0402 Check-Engine Light and Rough Idle (TSB 99-085)?
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.
What is the 1996-2005 Honda Civic Idle Air Control Valve Carbon Fouling — Hunting/High Idle and Stalling?
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.
What is the 2001-2020 Honda Civic P0741 — Torque Converter Clutch Stuck Off from a Failing TCC Lock-Up Solenoid / Worn Converter?
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.
What is the 2001-2005 Honda Civic 7th-Gen HVAC Blower Motor Resistor & Connector Overheating/Melting?
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.
What is the 2001-2011 Honda Civic Valve Cover Gasket Oil Leak — Burning Smell and Oil in Spark-Plug Wells?
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.
What is the 2001-2011 Honda Civic Power Window Regulator and Motor Failure?
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.
What is the 1996-2005 Honda Civic VTEC Solenoid Spool Valve Gasket Oil Leak?
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.
