Is the new Toyota Sienna only available as a hybrid?

Yes. Since the 2021 redesign, every Sienna is a 2.5L four-cylinder hybrid with an eCVT — there is no V6 or non-hybrid option at any trim level. If you want a gas-only Sienna, you're shopping 2020 or older.

What oil does the 2021+ Sienna hybrid take?

0W-16 full synthetic, 4.8 quarts with a filter change (4.4 without). Toyota permits 0W-20 if 0W-16 isn't available, but says to return to 0W-16 at the next change. It's straight from the hybrid owner's manual — this van never came any other way.

How much oil does the Sienna V6 take?

Depends on the year: the 2016 (2GR-FE) takes 6.4 quarts of 0W-20 with a filter change per Toyota's manual; the 2017–2020 (2GR-FKS) takes about 5.8 quarts — confirm that one in your own manual. Both use the 04152-YZZA1 cartridge filter.

How does AWD work on the hybrid Sienna?

There's no driveshaft. Toyota's E-Four system puts a 40 kW electric motor on the rear axle, and that rear unit holds 1.8 quarts of Toyota ATF WS. It's why the AWD hybrid gives up almost nothing in fuel economy.

Does the hybrid Sienna have a CVT with a belt?

No belt. The eCVT is a planetary gearset that blends the engine and two motor-generators — same architecture as the Prius, with a long reliability record. Its 4.6 quarts of ATF WS are serviced by dealer procedure.

What's the lug nut torque on a Sienna?

76 lb-ft (103 N·m), star pattern — Toyota prints the same figure for every wheel size in both generations.

2016–2024 Toyota Sienna Oil Capacity & Fluid Specs

Quick answer

The 2021–2024 Sienna — hybrid-only — takes 4.8 quarts of 0W-16 with a filter change. The 2016 V6 (2GR-FE) takes 6.4 quarts of 0W-20; the 2017–2020 V6 (2GR-FKS) about 5.8 quarts of 0W-20. All years use the Toyota 04152-YZZA1 cartridge filter, and lug torque is 76 lb-ft.

These are really two different vans wearing one name. Through 2020 the Sienna was a conventional 3.5L V6 — the 2GR-FE with a 6-speed through 2016, then the direct-injected 2GR-FKS with an 8-speed from 2017. In 2021 Toyota did something no other minivan maker had done: it dropped the gas engine entirely. Every 2021+ Sienna is a 2.5L hybrid with an eCVT, and its AWD has no driveshaft at all — an electric motor drives the rear axle. That changes everything at the parts counter: thin 0W-16 oil instead of 0W-20, a 4.8-quart fill instead of 6.4, and two separate pink-coolant circuits (engine plus power control unit). Specs below are verified against Toyota's own 2016, 2021, and 2023 owner's manuals; the 2017–2020 figures we couldn't check against an in-hand manual are flagged.

DIY oil change — quick steps

1 Set up

Warm engine, level ground. On 2021+ hybrids, make sure the hybrid system is fully OFF (no READY light) before working under the hood — the gas engine can start by itself when the system is live.
2 Drain

14mm drain plug, new aluminum gasket every time (Toyota 90430-12031). The V6 drains over six quarts — use a pan with real capacity.
3 Cartridge filter

Both the V6 and the hybrid use the 04152-YZZA1 cartridge: 64mm cap wrench, swap the element and BOTH O-rings (lightly oiled), torque the cap modestly — plastic housings crack from gorilla hands.
4 Refill, verify, reset

Fill per your engine's table — 4.8 quarts hybrid, 6.4 quarts 2016 V6, ≈5.8 quarts 2017–2020 V6 — check the dipstick after settling. Reset the maintenance light: 2021+, Settings → Vehicle settings → scheduled maintenance; older vans, ODO to Trip A, key off, hold the trip button while switching on until zeros.

Common problems on this vehicle

Fuel pump recall (2017–2020)

The 2017–2020 Sienna V6 is covered by the Denso low-pressure fuel pump recall (NHTSA 20V-682): the pump impeller can swell and stop turning, stalling the engine without warning — including at highway speed. The fix is a free dealer pump replacement. Run your VIN through our recall check before assuming yours was done.

Sliding doors — the Sienna's signature weak point

The 2016 model year falls inside recall 16V-858 (2011–2016 Siennas): a power sliding door that stalls while latching can end up able to open while the van is moving. Older XL30s also wore out door cables, which Toyota addressed with extended customer-support coverage. The redesigned 2021+ doors have no recall, but owner complaints about doors that stop responding are common enough to budget for — check your VIN either way.

Heard about V6 oil-line failures? Wrong era

The 2GR-FE's infamous rubber VVT-i oil-line leak hit engines built through early 2008, and Toyota's service campaign for it dates to 2010. A 2016 Sienna's 2GR-FE — and every 2GR-FKS after it — uses the updated line. Don't pay for a preventive replacement based on decade-old forum threads.

8-speed drivability complaints (2017–2020)

Early Direct Shift-8AT vans drew owner complaints about hunting and harsh low-speed shifts, and Toyota released transmission calibration updates over these years. If your 2017–2020 Sienna shifts rough, have the dealer check for updated software before anyone sells you hardware.
