Risk: A damaged parking rod can allow the vehicle to roll when parked, increasing the risk of a crash or injury.

Fix: Honda will notify owners, and dealers will ensure the battery terminal connections are secure and will update the TCU software, free of charge.

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

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

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Automatic Transmission / CVT Fluid (Sub-code 3)

Every 30,000 mi

Replace ATF or CVT fluid. Honda CVT models (Civic, HR-V, Accord LX) use Honda HCF-2 — do not substitute. The Maintenance Minder triggers earlier under heavy stop-and-go.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Rear Differential Fluid (AWD models, Sub-code 5)

Every 30,000 mi

AWD CR-V, Pilot, Passport, Ridgeline: replace rear diff fluid every 30,000 miles, sooner if towing.

Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Spark Plugs (Sub-code 6)

Every 105,000 mi

Honda uses iridium-tipped plugs rated for 100,000+ miles. Replace at 105,000 miles or whenever Sub-code 6 displays.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Engine Coolant (Sub-code 5)

Every 60,000 mi

Honda Long-Life Type 2 (blue) coolant: first change at 120,000 miles, then every 60,000 miles. Do not mix with other coolant types.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

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

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)

12 crashes 2010–2024

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number

Owner-reported problem signals

Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
