Honda Pilot 2016–2022Common problems, reliability & repair costs

Symptoms: Hard 1–2 and 2–1 shifts, a pause then a lurch when accelerating from a roll, clunks at parking-lot speeds, occasional hesitation before kickdown. Worst on 2016–2018 cars; owners and a class action blamed the transmission and powertrain control software.

Fix: Most cars are dramatically improved by the dealer software updates Honda released across the run — a $150–$250 visit if out of warranty, free if a campaign applies. Actual hardware failure is uncommon; a valve body or replacement 9HP48 is the rare worst case at $3,500–$5,000+. By the 2019 refresh the calibration was largely sorted, which is why late cars barely complain.

Symptoms: Check-engine light with random or single-cylinder misfire codes (P0300–P0306), rough idle, shaking at stops, hesitation. Caused by debris from machining in the direct-injection injectors/high-pressure pump — Honda's TSBs call for replacing all six injectors with an updated part.

Fix: Honda extended injector coverage to 10 years/150,000 miles (TSB 21-010, superseding 20-100 and A18-025) — a dealer replaces all six free if the VIN and failure conditions qualify. 2016 cars start aging out of the 10-year window in 2026, so out-of-pocket at an independent shop runs $800–$1,800 for six injectors installed.

Symptoms: The engine shuts off at a light as designed, then won't restart — dash lights up, no crank, car stranded in traffic. Some owners needed a jump start. NHTSA logged hundreds of complaints, opened an investigation on ~195,000 2016–2020 Pilots, and upgraded it in 2025 to cover over 2.2 million Honda/Acura vehicles.

Fix: Honda's TSBs 23-008/23-009 prescribe a fuel-injection software update first, then a starter assembly/relay replacement or valve adjustment if that fails — with a 10-year/unlimited-mileage warranty extension on the component fix. Out of that coverage, a starter replacement at an independent shop is roughly $450–$950. Some owners report failures even after the fix, which is why the federal investigation (EA25004) is still open. Cheap insurance: the idle-stop can be switched off every drive.

Symptoms: Engine knock or ticking from the bottom end, oil-pressure warning, stalling, or a no-start. Improperly ground crank pins from the factory accelerate rod-bearing wear; a seized bearing can kill the engine while driving. About 250,000 Honda/Acura V6 vehicles recalled in November 2023.

Fix: Free under recall 23V-751: dealers inspect the crankshaft and repair or replace the engine as needed — run the VIN to confirm it was done. The catch: NHTSA has since opened a new probe (PE25008) into V6 engine failures outside the recall's scope, so a knocking J35 that isn't VIN-covered is a $5,000–$8,000 used-engine job. Walk away from any example with bottom-end noise.

Symptoms: Battery dead overnight or after a day or two parked, keyless-start error messages, flickering exterior or dash lights, random warning-light storms. The keyless access control unit stays awake and parasitic-drains the battery; CarComplaints logs 600+ electrical complaints on the 2016 alone.

Fix: Diagnose the parasitic draw properly — the fix that sticks is replacing the keyless access control unit (plus the battery it murdered). Owners who just keep replacing batteries keep getting stranded. An independent shop can do the module and a quality battery for $250–$700 depending on parts pricing.

Symptoms: A vibration or shudder at steady light throttle between roughly 20 and 60 mph, like driving over mild rumble strips. Honda traced it to transmission fluid that degrades faster than expected under heat — not a failing torque converter.

Fix: TSB 17-014/17-015: a software update to manage fluid temperature plus fluid replacement with genuine Honda DW-1 (a triple drain-and-fill clears it in stubborn cases). Honda covered it 8 years/80,000 miles, now lapsed on these cars — but it's a cheap fix and an easy DIY (see repairs below). Use DW-1 only; aftermarket ATF can bring the shudder back.

Tools: 3/8-in ratchet (the drain plug takes a square drive), Drain pan, Funnel with long neck, Torque wrench, Ramps or jack + stands (level the car to check the fluid)

1. Warm the transmission with a short drive, then park level and remove the drain plug with a 3/8-in square drive; drain into a pan and measure what came out.
2. Replace the sealing washer, reinstall the drain plug, and torque to spec.
3. Refill through the dipstick/fill point with the same amount of genuine Honda DW-1 you drained (typically ~3–3.5 quarts per drain).
4. Run the shifter through all gears with the engine idling, then recheck the level warm on level ground.
5. For judder cars, repeat the drain-and-fill two more times with short drives between (the 'triple flush' from Honda's TSB) so mostly-fresh fluid ends up in the converter.

Tools: None (hands only; maybe a small screwdriver for the airbox clips)

1. Open the glovebox, squeeze the sides to release the stops, and swing it down to expose the cabin filter cover.
2. Slide the old cabin filter out and insert the new one with the airflow arrow pointing the direction marked on the housing.
3. Under the hood, release the airbox clips, lift the lid, and swap in the new engine air filter.
4. Re-seat the airbox lid, snap the clips, and reinstall the glovebox.

Tools: 10mm wrench or socket, Memory saver (optional but avoids radio/window relearns), Battery terminal brush

1. With the ignition off, disconnect the negative terminal first, then the positive (10mm nuts).
2. Remove the battery hold-down bracket and lift the old battery out.
3. Clean both terminal clamps with a terminal brush before installing the new battery.
4. Set the new battery, secure the hold-down, connect positive first, negative last, and coat the terminals.
5. If your Pilot keeps killing batteries, don't stop here — have the parasitic draw tested; the keyless access control unit is the usual culprit on 2016–2017 cars.
