Engine

2.0L Inline-4

• No Issues Found

1.5L Turbocharged Inline-4

• Oil Dilution
  • Description/Symptoms: Fuel mixes with the engine oil, leading to a higher oil level than normal, a gasoline smell in the oil, and potential engine damage. This issue is more prevalent in colder climates and with short trips where the engine doesn’t fully warm up.
  • Solution: Honda issued a software update to address the fuel injection strategy to reduce oil dilution. In severe cases, an oil change and inspection of the engine may be necessary. A redesigned A/C condenser was also implemented to warm up the engine faster.
  • Estimated Cost to Fix: Software update is typically free at a dealership. Oil change ~$50-100. Replacing the A/C condenser ~$400-800.
  • Recalls: None Found

Transmission

CVT (Continuously Variable Transmission)

• Jerky Acceleration/Hesitation
  • Description/Symptoms: Some owners report jerky acceleration, hesitation, or a “rubber band” feeling from the CVT, especially during low-speed maneuvers or when trying to accelerate quickly.
  • Solution: In some cases, a software update for the CVT control module can improve the issue. In other cases, replacement of the CVT may be needed.
  • Estimated Cost to Fix: Software update is typically free at a dealership. CVT replacement ~$3,000 - $5,000.
  • Recalls: None Found

Suspension

• Premature Wear of Rear Wheel Bearings
  • Description/Symptoms: Premature wear and tear of the rear wheel bearings can cause loud road noise and vibrations that can be felt inside of the cabin.
  • Solution: Replacement of the affected wheel bearings.
  • Estimated Cost to Fix: $300 - $600
  • Recalls: None Found

Electrical

• Battery Drain
  • Description/Symptoms: Some owners have reported issues with the battery draining overnight or within a few days of the vehicle sitting unused, leading to difficulty starting the car.
  • Solution: Potential causes include a faulty alternator, parasitic drain from an electronic component (e.g., infotainment system, door locks), or a bad battery. Diagnosis involves checking the charging system and performing a parasitic draw test. Replacement of the faulty component is then required.
  • Estimated Cost to Fix: New battery ~$100 - $300. Alternator replacement ~$300 - $600. Parasitic drain diagnosis and repair: $100 - $500+ depending on the source of the drain.
  • Recalls: None Found
• Infotainment System Issues
  • Description/Symptoms: The infotainment system can experience freezing, lagging, unresponsive touch screen, Bluetooth connectivity problems, and random reboots.
  • Solution: A software update may resolve the issue. If the problem persists, the infotainment unit may need to be replaced.
  • Estimated Cost to Fix: Software update is typically free at a dealership. Infotainment unit replacement ~$500 - $1500+.
  • Recalls: None Found

Exterior

• No Issues Found

Interior

• Cracking Dashboard (in certain climates)
  • Description/Symptoms: Some owners, particularly those in very hot and sunny climates, have reported cracking or warping of the dashboard material.
  • Solution: Replacement of the dashboard.
  • Estimated Cost to Fix: $1,000 - $2,000+ depending on labor and parts.
  • Recalls: None Found

Summary:

The 2018 Honda Civic is generally considered a reliable vehicle, but owners have reported some common issues. The most concerning problems relate to potential oil dilution with the 1.5L turbocharged engine and some CVT-related complaints. Electrical issues such as battery drain and infotainment system glitches are also relatively common. The severity and cost of repairs vary, with software updates being a low-cost solution, while engine or transmission replacements can be quite expensive. Potential buyers should be aware of these issues and thoroughly inspect any used 2018 Civic before purchase, paying close attention to the oil level, engine performance, transmission smoothness, and the functionality of all electrical systems.
