Reliability report · 2016 Honda Odyssey · Updated July 2026

The engine-misfire year — Honda's own piston-ring program is the safety net, so read the service history before you fall for the paint.

This is the second-to-last year of the fourth-generation Odyssey, and its defining problem comes from VCM — Variable Cylinder Management, Honda's fuel-saving system that shuts down three of the six cylinders when you're cruising gently. The cylinders it shuts down are the rear three, and over time their piston rings deteriorate, oil gets past them, the spark plugs foul and the engine starts misfiring. Owners describe a flashing check-engine light, shaking, and a van that feels like it's running on half an engine. Honda's own repair — cylinder-head disassembly and piston-ring replacement in cylinders 1 through 3 — is documented in service bulletin 25-061, with a warranty extension and a reimbursement programme for people who paid out of pocket first.

The rest of the 2016's file is mostly free work. Four separate recalls address second-row seats that can slide, tip or fold when they shouldn't — the single most important cluster on a van where a child seat lives in row two. There is a fuel-tank recall for bad welds and a fuel-pump recall that can cause a stall. None of that costs you anything; all of it needs the VIN checked. Buy a 2016 with the misfire work already done and documented, or with a compression and cylinder-leakdown check in hand — and confirm every seat recall is closed.

Canary status

Squawking

What that means: 263 federal complaints, and the loudest one is a single mechanical story: the engine misfires because the piston rings in the rear three cylinders wear out. That is a real, expensive repair — but Honda eventually admitted it, published a fix under service bulletin 25-061, extended the warranty for it and set up a reimbursement programme for owners who already paid. A 2016 with that work documented is a very different van from one where it hasn't happened yet.

Rear-bank misfire from piston-ring wear — and the Honda programme that covers it

major

The dominant 2016 complaint, and the reason this year is Squawking. The Odyssey's 3.5-litre V6 uses VCM — Variable Cylinder Management, a fuel-saving system that shuts down three of the six cylinders when the engine is barely working. Those three sit on the rear bank, and over tens of thousands of miles their piston rings deteriorate. Oil gets past the rings, fouls the spark plugs, and the engine misfires: a flashing check-engine light, heavy shaking, loss of power. Owners in the federal file report it at 76,000 and at 100,000 miles, with dealers diagnosing failed piston rings outright. Honda's answer is service bulletin 25-061 — a repair involving cylinder-head disassembly and replacement of the piston rings in cylinders 1 to 3, backed by a warranty extension and a reimbursement programme (a 'warranty extension' is Honda quietly agreeing to pay for a repair after the normal warranty has run out; the reimbursement programme pays back owners who already footed the bill). One owner's reimbursement request for the job was $1,859.90. Several owners report reimbursement claims sitting unpaid for months. Ask directly whether this work has been done, get the invoice, and if it hasn't, have a compression and cylinder-leakdown test done before you buy.

Four second-row seat recalls — the ones that matter most in a minivanmajor

The 2016 carries four separate federal recalls on the second-row seats, which is where most families put a child seat. Recall 16V-932 covers the second-row centre seat, whose horizontal adjuster bar can stick unlocked and let the seat slide — a failure to meet the federal seat-systems standard, and it applies to vans built in a narrow window in autumn 2016. Recall 16V-933 covers the second-row outboard seats, whose walk-in release lever can stay unlocked so the seat moves unexpectedly. Recall 17V-725 covers those same outboard seats failing to latch properly to the floor striker, so the seat can tip forward under braking. Recall 18V-170 covers the left outboard seatback free-folding after the walk-in lever is used on a fully reclined seat. All four are free, all four are fixed with brackets, springs or replacement parts, and all four are individually checkable by VIN. Do not take 'the recalls are done' on trust — check each of these four by number.

All four seat recalls

Fuel-tank welds and the in-tank fuel pump — 16V-417, 23V-858moderate

Two fuel-system recalls, both free. Recall 16V-417 covers fuel tanks built with insufficient welds that can separate and let fuel leak — a fire risk, remedied by replacing the tank outright (Honda's internal code KA9). Recall 23V-858 is the very large in-tank fuel-pump campaign that runs across most of Honda's range: the pump can fail and stall the engine while you're driving. Dealers replace the pump module free of charge; owner letters went out in September 2024. Owners of 2016 vans in the federal file describe exactly that failure, including one dealer report that a pump 'almost exploded'. Both are VIN-specific, so check both.

Fuel-tank replacement and fuel-pump module, both under recall

Sliding doors, rear camera and the small stuffminor

The 2016's sliding doors are in better shape than the years that follow, but they have their own footnotes. Honda issued a Product Update — its term for a free dealer fix that isn't a safety recall — for 110 vans whose driver's-side sliding door had three spot welds at the top left unprimed, leaving bare metal that can rust. A separate service bulletin (a TSB, or Technical Service Bulletin: the fix instructions Honda sends its dealers) covers a bad crimp in the sliding-door rear latch switch wiring that makes the door-ajar beeper sound while you drive even though the doors are properly shut. Separately, owners report rainwater getting into the rearview camera and turning the image blurry — a nuisance on this year rather than a campaign, though Honda would later recall the same failure on 2018–2020 vans. Test both doors through several full open-and-close cycles and check the camera image after rain.

The dealership performed repairs in accordance with Service Bulletin 25-061, which included cylinder head disassembly, replacement of piston rings (cylinders 1-3).
