2016 Honda Pilot Fuel Injector Misfires: What It Really Costs to Fix
Quick answer: 2016 Honda Pilot fuel injector misfires is free to fix on recall-covered VINs and up to $1,800 out of pocket otherwise.
Applies to: every version of this generation.
What the Issue Is
The documented misfire problem on 2016 to 2019 Pilots is the fuel injectors. The 3.5-liter V6 uses direct injection, and failing injectors can set misfire codes (P0300 to P0306), air-fuel imbalance codes (P219A, P219B) and catalyst-efficiency codes (P0420, P0430), with a steady or flashing check-engine light, rough running and hesitation.
Honda's answer is a 2021 warranty extension on the fuel injectors: 10 years from the original purchase date or 150,000 miles, whichever comes first, and it transfers to later owners. It came as two notices: one for 2016 to 2017 Pilots (with 2017 Ridgelines and 2018 Odysseys) whose repair also includes a PCM software update, and one for 2017 to 2019 Pilots (with 2017 to 2019 Ridgelines and 2018 to 2019 Odysseys) without the software step. Repairs under it are free when the codes trace to the injectors.
The calendar is the catch on a 2016. Ten years from the original sale has already run out for most 2016 Pilots by late 2026 and is running out for 2017s sold in 2016; later 2017 to 2019 Pilots stay covered until their tenth anniversary unless they pass 150,000 miles first. Paperwork showing injectors replaced under the extension is worth having on any of these cars.
Symptoms to Watch For
- 1.Check-engine light, steady or flashing, with misfire codes P0300 to P0306
- 2.Air-fuel imbalance codes P219A or P219B
- 3.Catalyst efficiency codes P0420 or P0430
- 4.Rough idle, stumble or hesitation under load
Real Repair Costs
Free under Honda's injector warranty extension while the car is inside 10 years from its original sale and under 150,000 miles. Out of coverage, the usual repair replaces all six injectors as a set with the fuel joint pipe and seals; the range is an estimate built from Go-Parts injector pricing and YourMechanic's injector labor on the older Pilot V6.

Moderate issue. Ranges are US independent-shop estimates with quality parts. Use them as negotiation grounding, not a quote.
Mechanic's Tip: Spot It Before You Buy
Bring a $20 code reader and check for stored and pending misfire (P0300 to P0306), imbalance (P219A/P219B) and catalyst (P0420/P0430) codes before anything else; a car whose codes were just cleared will show readiness monitors not yet complete, which is its own clue. Then ask the seller, or a Honda dealer by VIN, whether injectors were replaced under Honda's 2021 extension: on a 2016 the 10-year window has most likely closed, so a car with the work already done is the version to want.
The Bigger Ownership Picture
Beyond this specific issue, budget roughly $1,100-$1,700 per year for scheduled maintenance and likely out-of-warranty repairs on a 2016 Honda Pilot. That is a typical US range from Avturo's ownership-cost table, an estimate rather than a quote, and it excludes insurance, fuel, and financing.

Frequently Asked Questions
Why does my Pilot have misfire codes?▼
On 2016 to 2019 Pilots the documented cause is the fuel injectors: Honda extended injector coverage in 2021 because failing injectors set misfire (P0300 to P0306), air-fuel imbalance (P219A/B) and catalyst (P0420/P0430) codes. Plugs and coils can also cause misfires, so a shop should confirm the cause before replacing parts.
Did Honda extend the warranty for Pilot misfires?▼
Yes, for the injectors: a 2021 warranty extension covers fuel injectors on 2016 to 2019 Pilots for 10 years from the original purchase date or 150,000 miles, whichever comes first, and it transfers to later owners. Ten years has already passed for most 2016 Pilots by late 2026, so a dealer VIN check tells you whether a given car is still inside it.
What does Pilot injector replacement cost without coverage?▼
Roughly $900 to $1,800 at an independent shop by our estimate: the usual repair replaces all six injectors as a set along with the fuel joint pipe and seals, and on this direct-injection V6 the labor is a large share of the bill. Check the VIN first; the extension still applies to many 2017 to 2019 Pilots under 150,000 miles.
What should I check before buying a used Pilot?▼
Scan for misfire, imbalance and catalyst codes, ask for injector paperwork, confirm the trim (2016 to 2020 Touring, Elite and Black Edition have the nine-speed, which is its own topic), and have a Honda dealer check by VIN whether the injector extension and the transmission software updates apply or were done.
