FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP
Campaign #19V053000 · Jan 24, 2019
Issue: Honda (American Honda Motor Co.) is recalling certain 2017-2019 Ridgeline trucks. Exposure to acids, such as from car wash soaps, can result in the fuel pump feed port cracking.
Risk: A crack in the fuel pump feed port can allow pressurized fuel to leak out, increasing the risk of a fire.
Fix: Honda will notify owners, and dealers will replace the fuel pump, if necessary, and install a fuel pump cover, free of charge. The recall began March 14, 2019. Owners may contact Honda customer service at 1-888-234-2138. The recall number for this recall is Q3V.
SEATS
Campaign #18V221000 · May 4, 2018
Issue: Honda (American Honda Motor Co.) is recalling certain 2018 Honda Pilot and Ridgeline vehicles and 2018 Acura MDX vehicles. The front driver and passenger powered seats in the Honda vehicles and the driver powered seats in the Acura vehicles may have been assembled with improperly manufactured rivets. In the event of a crash, the rivets can break causing the seats not to be secured to the floor. As such, these vehicles may fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 207, "Seating Systems," and 210, "Seat Belt Assembly Anchorages."
Risk: In the event of a crash, if the seat does not remain secured to the floor, the seat occupant has an increased risk of injury.

Issue: Honda (American Honda Motor Co.) is recalling all Honda Genuine Accessory Tonneau Covers, part number 08Z07-T6Z-100F, sold for installation on 2017-2020 Ridgeline trucks. If the tonneau cover is not properly secured in the open or closed position, wind resistance may cause the cover to flip and buckle. If this occurs, the hinges between the center and rear panel may deform, possibly allowing the rear panel to separate from the vehicle.
Risk: A separated panel may become a road hazard, increasing the risk of crash or injury.
Fix: Honda will notify all registered owners of 2017-2020 Honda Ridgelines, and dealers will install tethers onto any Honda Genuine Accessory Tonneau Cover to prevent panel separation and apply warning labels, free of charge.

Critical for safety and preventing major damage
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.
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.
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.
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.
Keeps your vehicle running smoothly and efficiently
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.
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.
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.
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.
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.
Extends the life of your vehicle and improves comfort
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.

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.
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.

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