At 120,000 miles, your 2018 Honda Accord hits a major maintenance milestone. This is when Honda recommends replacing spark plugs if they haven't been replaced yet, plus inspecting all major systems to catch potential issues early.
What Gets Done at 120,000 Miles
Here's what your Accord needs at this service interval:
- Replace spark plugs (if needed based on previous service history)
- Inspect all major systems including engine, transmission, suspension, and brakes
- Check engine oil and coolant levels
- Inspect front and rear brakes for wear and condition
- Rotate tires and check tire inflation and condition
- Inspect brake hoses and lines (including ABS)
- Check all fluid levels and look for leaks
- Inspect the exhaust system
- Inspect fuel lines and connections
- Check all lights
- Inspect the vehicle underbody
Why This Service Matters
At 120,000 miles, your Accord has significant mileage. This inspection catches wear before it becomes an expensive problem. The spark plug replacement is important because worn plugs reduce fuel efficiency and engine performance.
If your vehicle is driven in severe conditions like dusty areas, frequent towing, or stop-and-go traffic, you may need to service some items sooner. Check your owner's manual or Maintenance Minder display for condition-specific recommendations.
How to Stay on Track
Your 2018 Accord has a Maintenance Minder system that alerts you on the multi-information display when service is due. This system considers mileage, driving conditions, and engine load to give you accurate timing. Regular maintenance at recommended intervals helps your Accord run reliably and maintain its resale value.
