Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter (Code A)

Every 7,500 mi

Replace 0W-20 full-synthetic oil and filter. The Maintenance Minder triggers Code A between 7,500 and 10,000 miles depending on driving conditions.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation (Sub-code 1)

Every 7,500 mi

Rotate tires front-to-back to even out wear. Honda triggers Sub-code 1 alongside every other oil change.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection (Code B)

Every 15,000 mi

Inspect brake pads, rotors, and parking brake. Code B includes a multi-point inspection of brakes, suspension, and fluids.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Brake Fluid (Sub-code 5)

Every 45,000 mi

Replace DOT 3 brake fluid every 3 years regardless of mileage to prevent moisture absorption and corrosion of ABS components.

Extends the life of your vehicle and improves comfort

Cabin Air Filter (Sub-code 3)

Every 15,000 mi

Replace the cabin air filter — accessible behind the glove box on most Hondas. Honda recommends 15,000 miles in dusty conditions, longer in clean climates.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

Valve Clearance Adjustment (Sub-code 6)

Every 105,000 mi

Inspect and adjust valve clearances at 105,000 miles. Critical on K-series and L-series engines to prevent valve recession.

Estimated cost — typical U.S. ranges

Dealer

~$495–$535

Shop

~$345–$375

DIY

Pro only

Mechanical-bucket valvetrains (many Honda 4-cyls, older Toyotas) need this. Hydraulic lifters don't. Shop work — feeler-gauge precision required.

Timing Chain — No Replacement

On condition / lifetime

Modern Honda engines (K-series, L-series, R-series, plus all Earth Dreams 1.5T and 2.0T) use a timing chain designed to last the life of the engine. No scheduled replacement.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Pro only

Timing chains are normally lifetime. Listen for rattle on cold start — that's the actionable signal. Replacement is major work, quote separately.

Fatal crash history & reported problems

Occupant deaths in fatal crashes (FARS)
