Campaign #20V438000 · Jul 28, 2020

Issue: American Honda Motor Co. (Honda) is recalling certain 2019-2020 Odyssey vehicles. Water may get into the rearview camera mounting holes and enter the camera lens and cause a distorted image, or no image at all.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rearview Mirrors."

Risk: A distorted or inoperative rearview camera display can reduce the driver's view of what is behind the vehicle, increasing the risk of a crash.

Fix: Honda will notify owners, and dealers will replace the rearview camera, free of charge. The recall began September 23, 2020. Owners may contact Honda customer service at 1-888-234-2138. Honda's number for this recall is W83.

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.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

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.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

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

💨

Engine Air Filter (Sub-code 4)

Every 30,000 mi

Replace the engine air filter every 30,000 miles. Honda uses a long-life cellulose element on most port-injected engines.

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.

Recommended maintenance

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.
