2027 Toyota Sienna: What Toyota Has and Has Not Announced

Release date: Toyota has not announced the 2027 Sienna or a release date as of October 2026; last year it announced the 2026 Sienna on October 23, 2025, with dealer arrivals expected in January 2026. Redesign: not announced; the current fourth-generation Sienna launched for the 2021 model year as a hybrid-only minivan, and the 2026 changes were equipment and colors.

Has Toyota announced the 2027 Toyota Sienna?

No. Toyota’s What’s New for 2027 page is a navigation hub that says additional information about 2027 vehicles will be added as it becomes available, and it carries no Sienna information. The Sienna still appears under its 2026 name in the newsroom menus. Searches for a dedicated Toyota 2027 Sienna release turn up only dealer and aggregator pages, which are not Toyota announcements and are not used for specs here.

That leaves two honest answers for shoppers: the 2027 Sienna may be a carryover, or it may include changes, and Toyota has said neither. The sections below give the verified 2026 numbers and how Toyota timed the last model year, so you can judge what to expect without any unconfirmed claim. Treat any article that quotes a 2027 Sienna price, hp or mpg as unverified until it links to pressroom.toyota.com or fueleconomy.gov, because neither source has published them as of this writing.

Is the 2027 Toyota Sienna a Redesign?

Toyota has not said. Its What’s New for 2027 page carries no Sienna details as of October 6, 2026, so a redesign is neither announced nor ruled out. The current fourth-generation Sienna (XL40) was redesigned for the 2021 model year and has been hybrid-only since (Wikipedia). Toyota revealed that generation on May 18, 2020, and its October 27, 2020 release said the 2021 Sienna would reach dealerships that November. Toyota’s 2026 Sienna release, dated October 23, 2025, described additions of equipment and paint rather than mechanical changes, with the same 245 hp hybrid system. Minivans from Toyota have typically run several years per generation, but that is a pattern, not an announcement. Until Toyota publishes a 2027 release, treat any redesign claim as unverified.

What are the 2026 Toyota Sienna specs?

Every Sienna is a hybrid. There is no gas-only version, and AWD is rated 1 mpg lower in the city and combined. Toyota’s 2026 warranty terms are 36 months or 36,000 miles basic, 60 months or 60,000 miles powertrain, 8 years or 100,000 miles on the hybrid system and 10 years or 150,000 miles on the hybrid battery.

What changed on the 2026 Sienna?

Toyota’s October 23, 2025 release is headlined “2026 Toyota Sienna Packs in More Standard Features.” Changes were equipment and color additions rather than mechanical.

• Current 2026 figure: the entry LE adds an 8-speaker audio system, power rear door, rear window shades, auto-dimming mirror and de-icer, plus a power tilt and slide moonroof per Toyota’s newsroom page.
• Current 2026 figure: the XSE gets a JBL Premium Audio system with 12 speakers, a subwoofer and an amplifier.
• Current 2026 figure: Heavy Metal exterior paint arrives across several grades, and the Woodland grade gets Ice Cap as a paint option.

When Is the 2027 Toyota Sienna Release Date?

Toyota has given no 2027 Sienna date. The only precedent is last year’s schedule. Toyota announced the 2026 Sienna on October 23, 2025 and said it was expected to start arriving at dealerships in January 2026, which is a gap of roughly two to three months. A year earlier, Toyota announced the 2025 Sienna on September 17, 2024, from $39,185 for the LE FWD excluding dealer processing and handling, and said it would start arriving at dealerships in fall 2024. The 2027 Tundra and Grand Highlander were announced on July 21 and October 1, 2026, so Toyota is releasing 2027 information model by model. If the Sienna follows last year’s pattern, an announcement could come in the fall, but Toyota has not committed to this and the pattern is not a prediction.

2027 vs 2026: what is confirmed and what is not?

How does the Sienna compare with the Grand Highlander on official numbers?

Shoppers weighing a minivan against a three-row SUV can use the official Toyota figures. The Grand Highlander has a 2027 release dated October 1, 2026, which confirms its powertrains for the new model year, while the Sienna figures are from 2026.

On those numbers the Grand Highlander leads on peak output by 117 hp, while the Sienna is the one with a published 36 mpg combined rating. Cargo is not directly comparable because the Toyota Sienna release does not list a figure.

What should you look for when Toyota publishes 2027 Sienna details?

• Whether Toyota restates the 245 hp hybrid system and the 36 and 35 mpg EPA ratings.
• The starting price for the LE and whether the $40,120 figure moves.
• Any change to standard equipment on the LE, XLE and XSE grades, which received additions for 2026.
• Whether the Woodland Edition returns and keeps its standard AWD.
• The dealer arrival window, which Toyota gave as January for the 2026 model.

Should you buy a 2026 Sienna or wait for the 2027?

The official data supports a simple rule. If the 2026 Sienna’s 36 mpg, 245 hp and eight-seat layout fit your needs and a 2026 is available at a good price, you are not giving up any announced 2027 feature, because none is announced. If you are waiting for a specific change, such as a different grade lineup or new standard equipment, there is no official signal that it is coming.

One pricing caution applies to either year. The $40,120 figure excludes dealer processing and handling, and the Toyota release does not state a destination charge, so the delivered price will be higher. Compare the full window sticker, not the headline starting price, and use our free VIN decoder to confirm the year and trim of any used or in-stock unit.

Recent Toyota Sienna recalls: NHTSA’s recall database, which files the current van as the Sienna Hybrid, lists four Toyota campaigns reported since February 2025 that cover 2021-2026 models. The newest, filed in October 2026, involves the second-row seat backs. Each remedy is free at Toyota dealers.

• 26V690 (reported October 20, 2026), 2022-2026 Sienna Hybrid 7-passenger: the second-row seat backs may not stay secured in a crash. Dealers will update the supplemental restraint system (SRS) control-unit software, and vans with the Mobility as a Service (MaaS) package get two new second-row seat backs. Owner letters are expected December 7, 2026.
• 25V744 (October 30, 2025), 2025 Sienna Hybrid with Panoramic View Monitor: part of a multi-model Toyota, Lexus and Subaru recall. The rearview camera image may freeze or go blank in reverse. Dealers update the parking assist software.
• 25V668 (October 7, 2025), 2025 Sienna Hybrid: the second-row seat rails may be improperly welded. Dealers replace the second-row seat rails.
• 25V086 (February 13, 2025), 2021-2025 Sienna Hybrid: the third-row seatback bolts may not be tightened properly. Dealers tighten the bolts.

Older Toyota campaigns for these years are 22V239 (2021-2022, stability control software that may not switch back on at restart; fixed with a software update) and 21V889 (2022 eight-seat models, a wrong second-row seat belt webbing guide; fixed with new seat belt assemblies). Two equipment makers, Rollx Vans (25V876, 2024-2025 models) and Vantage Mobility (25V877, 2021-2025 models), recalled wheelchair-accessible conversions with QRT-Deluxe or QRT-Max restraints whose retractors may not lock; the fix is new retractors. To check a specific van, decode its VIN with our free VIN decoder to confirm the model year, then use the NHTSA recall link in the results to see any open recall for that vehicle.
