What is the 2017-2025 Honda Civic Type R Brake Fade and Fluid Boiling on Track (Stock Brakes)?
The FK8 and FL5 Civic Type R stock Brembo brake calipers with 350mm front rotors are adequate for street use but suffer brake fade after 2-3 laps on a circuit. The stock brake fluid (Honda Ultra Brake Fluid) has a wet boiling point of only 284°F, which is quickly exceeded on trac… Repairs typically run $150-$600. Severity: high.
What is the 2016-2022 Honda Civic 1.5T Turbo Engine Coolant Intrusion Into Cylinders / Head Gasket Degradation (Class Action)?
A class-action lawsuit (filed in U.S. and Canadian courts) alleges the turbocharged 1.5L i-VTEC engine cannot properly manage the added compression and heat, so engine coolant seeps through grooves in the cylinder head, degrades the head gasket, and leaks INTERNALLY into the comb… Repairs typically run $1,500-$8,000. Severity: high.
What is the 2016-2021 Honda Civic 1.5T Earth Dreams Direct Injection Carbon Buildup on Intake Valves?
The 1.5L turbocharged Earth Dreams direct-injection engine (L15B7) accumulates heavy carbon deposits on intake valves and ports because fuel is injected directly into the cylinder, bypassing the intake valves. Unlike port-injection engines, no fuel washes the intake valves clean. Repairs typically run $300-$800. Severity: medium.
What is the 2016-2020 Honda Civic Engine Oil Dilution from Fuel?
The 1.5L turbo engine can experience fuel mixing with engine oil during cold weather operation or short trips. This raises oil levels and reduces lubrication effectiveness. Honda extended the powertrain warranty and released software updates to address this. Repairs typically run $0-$150. Severity: medium.
What is the 2016-2023 Honda Civic A/C Compressor Failure?
The A/C compressor can fail, particularly on vehicles in hot climates or those with high A/C usage. When the compressor fails internally, it can contaminate the entire A/C system with debris, requiring extensive repairs. Repairs typically run $600-$1,800. Severity: medium.
What is the 2016-2023 Honda Civic CVT Shudder/Judder During Acceleration?
The CVT transmission can develop a shudder or judder, particularly during light acceleration from a stop or at low speeds. This vibration can feel like driving over rumble strips and is often related to the torque converter or CVT fluid degradation. Repairs typically run $150-$3,000. Severity: medium.
What is the 2016-2023 Honda Civic Honda Sensing System False Alerts/Phantom Braking?
The Honda Sensing driver assist system can experience false alerts and phantom braking, particularly with the adaptive cruise control and collision mitigation. The system may brake unexpectedly when no obstacle is present or fail to detect vehicles ahead. Repairs typically run $0-$500. Severity: medium.
What is the 2016-2021 Honda Civic 1.5T Turbocharger Coolant and Oil Line Leaks?
The 1.5L turbo Civic experiences premature failure of the turbocharger coolant feed and return hoses, and the oil feed/return lines. The banjo bolt sealing washers (crush washers) on the oil feed line compress and leak over time, causing slow oil loss near the turbo. The coolant… Repairs typically run $100-$1,400. Severity: medium.
What is the 2017-2025 Honda Civic Type R Limited Slip Differential Noise and Chattering?
The FK8 and FL5 Civic Type R uses a Torsen-style mechanical limited slip differential (LSD) that produces chattering, grinding, or clicking sounds during low-speed turns, especially in parking lots and during U-turns. This is inherent to LSD operation but becomes problematic when… Repairs typically run $100-$1,500. Severity: medium.
What is the 2016-2021 Honda Civic A/C Condenser Refrigerant Leak — Pinhole Corrosion Causing Warm Air (Warranty Extension, TSB 19-091)?
10th-gen Civics commonly lose A/C cooling because the factory condenser was not manufactured to specification: tiny corrosion holes form in the condenser tube walls and slowly leak refrigerant, so the A/C blows warm or only mildly cool air. The problem is widespread enough that H… Repairs typically run $0-$900. Severity: medium.
What is the 2016-2019 Honda Civic Body Control Module Parasitic Battery Drain?
Owners of 10th-gen Civics, especially 2017s, report the Body Control Module (BCM) failing to fully power down after the car is shut off, leaving a parasitic current draw that flattens the 12V battery overnight or over a few days. Because the BCM stays partially awake, the drain c… Repairs typically run $150-$900. Severity: medium.
What is the 2016-2021 Honda Civic A/C Condenser and Compressor Refrigerant Leak (R-1234yf System)?
The 10th-generation Civic's air-conditioning system, which uses the newer R-1234yf refrigerant, is prone to refrigerant leaks from two points. Condensers built out of spec corrode and develop pinhole leaks in the tube walls, and the A/C compressor shaft seal wears abnormally and… Repairs typically run $0-$2,000. 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 2016-2023 Honda Civic Thin Windshield Cracks/Chips Easily From Minor Impacts (ADAS Glass)?
Owners across 10th- and 11th-gen Civics report the windshield chips and cracks far too easily — from tiny pebbles, temperature changes, or with no apparent impact at all (cracks starting at the edge/seal). The modern thinner laminated glass (lighter and designed around the Honda… Repairs typically run $300-$1,500. Severity: medium.
What is the 2017-2022 Honda Civic Type R (FK8) 6-Speed 3rd-Gear Synchro Crunch on Cold/Fast Upshifts?
Early FK8 Civic Type R 6-speed manuals can exhibit a crunch/grind when shifting into 3rd gear — most noticeable on fast upshifts or when the gearbox oil is cold — caused by premature wear of the 3rd-gear synchromesh ring. Some owners also report 3rd/4th-gear failures under hard t… Repairs typically run $700-$3,000. Severity: medium.
What is the 2016-2018 Honda Civic 1.5T Cold-Weather Misfire from Fuel Injector Leakage — PGM-FI Software (TSB A19-033)?
On 1.5T Civics, fuel injectors can leak/over-deliver fuel — worst in cold weather and on short trips — causing single- or multi-cylinder misfires (P0301-P0304 / P0300) and contributing to fuel-in-oil dilution and spark-plug fouling. Honda addressed it with TSB A19-033 (NHTSA TSB… Repairs typically run $0-$800. Severity: medium.
What is the 2016-2021 Honda Civic Infotainment System Lag/Freezing?
The Honda infotainment system can experience lag, freezing, and unresponsive touchscreen inputs. The volume knob may be slow to respond, and the system can reboot randomly. CarPlay/Android Auto connections can be unstable. Repairs typically run $0-$1,000. Severity: low.
What is the 2016-2023 Honda Civic Rear Brake Squeal/Noise?
Many Civic owners report squealing or grinding noise from the rear brakes, often during light braking or when brakes are cold. This can occur even with adequate pad thickness and is often related to the pad compound or rotor surface condition. Repairs typically run $50-$400. Severity: low.
What is the 2016-2023 Honda Civic Front Suspension Clunk/Rattle?
A clunking or rattling noise from the front suspension when going over bumps is common. This can be caused by worn stabilizer bar end links, strut mounts, or control arm bushings. The issue may be more noticeable on rough roads. Repairs typically run $80-$400. Severity: low.
What is the 2006-2022 Honda Civic P0442 — Small EVAP Leak from a Degraded Gas Cap Seal or Cracked Vapor Hose?
P0442 sets when the Civic's PCM runs its EVAP self-test and detects a small leak (roughly 0.020-0.040 in). On the Civic the overwhelmingly most common source is the fuel-filler cap: the rubber O-ring on the cap hardens and shrinks with age/heat and stops sealing, which is why a P… Repairs typically run $20-$300. Severity: low.
