The Honda Civic Sedan, especially the 2018-2021 model years, is widely regarded as a dependable, affordable, and fuel-efficient vehicle. Known for its versatility and strong resale value, the Civic remains a top choice among compact cars. However, even this trusted model is not without its issues. In this in-depth guide, we’ll explore the common problems affecting the 2018-2021 Honda Civic Sedan, including essential tips for prospective buyers and an overview of ownership costs.
Common Problems with the 2018-2021 Honda Civic Sedan
1. Infotainment System Glitches and Screen Unresponsiveness
One of the most frequently reported issues with the 2018-2021 Honda Civic involves its infotainment system. Users have reported problems with the touchscreen display, including lag, freezing, and outright unresponsiveness. In particular, the system may reboot itself unexpectedly or struggle to connect reliably to smartphones through Apple CarPlay or Android Auto. Some drivers also experience a blank screen, making it difficult to adjust settings, navigate, or play media.
Underlying Causes:
- Software Bugs: Honda has issued software updates to address some of these issues, as they are primarily related to software instability.
- Hardware Wear: Over time, the touchscreen or main unit may degrade, resulting in unresponsiveness.
Possible Solutions:
- Software Update: Check with a Honda dealership to see if your vehicle’s infotainment system requires a software update.
- Hard Reset or Replacement: For persistent issues, a hard reset of the system may help, though some owners have had to replace the infotainment system at their own cost.
Estimated Repair Costs:
- Software Update: Often free at dealerships.
- Replacement Cost: Replacing the infotainment unit may cost between $400 and $1,200, depending on parts and labor.
2. Fuel Pump Recall Issues
In 2020, Honda issued a recall affecting certain 2018-2021 Civics due to faulty fuel pumps. The issue involves fuel pumps manufactured with low-density impellers that can absorb fuel, swell, and deform, leading to engine stalling or failure to start. This defect is potentially dangerous, especially if it leads to engine stalling at high speeds.
Underlying Causes:
- Material Defect: The low-density impellers in the fuel pump can swell and fail over time, particularly in extreme temperatures.
Possible Solutions:
- Recall Repair: This issue is part of a recall, meaning Honda will replace the fuel pump for free if your car is affected.
Estimated Repair Costs:
- Recall Repair: No cost if addressed through Honda’s recall program.
3. CVT Transmission Problems
Honda Civics equipped with the Continuously Variable Transmission (CVT) have reported occasional transmission issues. Some of the common symptoms include delayed shifting, surging, hesitation, and a jerking sensation during acceleration. This can affect the overall driving experience, reducing the smoothness that Honda Civics are known for.
Underlying Causes:
- Transmission Fluid Breakdown: CVT transmissions rely heavily on high-quality transmission fluid, and low or degraded fluid can lead to performance issues.
- Software Calibration: Some Civics may experience transmission issues due to calibration settings that could require updates.
Possible Solutions:
- Fluid Replacement: Regular CVT fluid changes are essential to maintain transmission health.
- Transmission Reprogramming: In some cases, a software update or reprogramming at a Honda dealership may resolve the issue.
Estimated Repair Costs:
- Transmission Fluid Change: Generally costs between $100 and $150.
- Transmission Reprogramming: Typically ranges from $80 to $200, depending on the dealership.
4. AC Compressor Failure
The air conditioning system in the 2018-2021 Honda Civic is another commonly reported issue. Some owners have noted that their AC blows warm air or that the compressor fails entirely. This problem is particularly troublesome in warmer climates, where reliable AC performance is essential for comfort.
Underlying Causes:
- Faulty Compressor Design: Some models may have defective compressors that fail prematurely.
- Refrigerant Leaks: Leaks in the AC system can result in low refrigerant levels, reducing the system’s ability to cool.
Possible Solutions:
- Compressor Replacement: If the compressor fails, it typically needs to be replaced.
- Leak Repair and Refrigerant Refill: If a leak is the culprit, locating and repairing it, followed by a refrigerant refill, may restore AC performance.
Estimated Repair Costs:
- Compressor Replacement: This repair can cost between $800 and $1,500, depending on the shop and whether OEM parts are used.
- Leak Repair and Refill: A refill alone might cost around $150-$250, while repairing leaks could add an additional $300-$700.
5. Brake Pad and Rotor Wear
Premature brake pad and rotor wear is a concern among some 2018-2021 Civic owners. The Civic’s braking system, especially in models driven in urban or stop-and-go traffic, may require frequent replacement of brake pads and sometimes rotors. Some owners report a squealing noise, vibration, or even grinding when applying the brakes.
Underlying Causes:
- Pad Material: The Civic’s OEM brake pads may wear out faster than expected under certain driving conditions.
- Driving Style: Frequent braking in city traffic or aggressive driving can accelerate pad and rotor wear.
Possible Solutions:
- Quality Aftermarket Pads and Rotors: Replacing OEM pads with high-quality aftermarket pads can improve longevity.
- Regular Inspection and Replacement: Routine inspection ensures that worn pads and rotors are replaced before they cause more serious damage.
Estimated Repair Costs:
- Brake Pads: Replacing pads typically costs $150 to $300.
- Brake Rotors: Replacing rotors along with pads can raise the total to $500 to $800.
6. Paint and Body Quality Issues
Some owners report paint quality issues, particularly on the hood and roof areas, where fading, chipping, or peeling may occur prematurely. While Honda has improved its paint technology over the years, environmental factors and sun exposure can affect the longevity of the Civic’s exterior finish.
Underlying Causes:
- Sun Exposure and Weather: Prolonged exposure to UV rays and environmental elements can accelerate paint degradation.
Possible Solutions:
- Regular Waxing and Coating: Protective coatings and regular waxing can help protect the paint from damage.
- Respray: In severe cases, a partial or full respray may be necessary.
Estimated Repair Costs:
- Respray Costs: Depending on the level of repair needed, respraying affected areas can cost $500 to $1,500.
What to Look For When Buying a 2018-2021 Honda Civic Sedan
When shopping for a used 2018-2021 Honda Civic, check for a documented service history, especially concerning the CVT transmission fluid, brake wear, and any past recall work. Ensure the AC blows cold air and the infotainment system operates without glitches. Look for signs of body and paint quality, as fading or peeling can indicate prolonged exposure to harsh weather without protection. A pre-purchase inspection by a mechanic is advised to identify potential issues before buying.
