Hi Sienna family,
Toyota has released updates for 2023 Sienna and nothing much changed. So what will be 2024 updates looks like? We get our closest guess by looking at Chinese Sienna.
All the images are captured from Toyota China: 赛那官方网站
Updates looking forward to in 2024
  • Dual power sunroofs
  • 12.3 inch Infotainment system
  • 12.3 inch TFT Multi-Information Display
  • Powered 2nd row captains’ seats
  • Additional USB C ports with cup holders for 2nd row captains’ seats
  • Smart PM2.5 cabin air filter system (maybe a Chinese market only)
  • Spare tire without loses ottoman chair.
By the way Chinese made Sienna are about $10k - $12k more compare to US models.
Tell me what do you think?

Huge infotainment system although I don’t see any physical volume/power button.

I’m on my phone, but looks like the 2nd row seats may still be non removable. Looks like they have them pushed all the way against the funny seats from what I can make out.
You are right about 2nd row seats not been removable. Big mistake by Toyota.

Someone needs to tell Toyota China to stop distorting their pictures so much that the grownup dude in pic. 2024d looks like he is 3.5 feet tall :)

Also, am I the only one who thinks that the larger the infotainment screen, the more awkward it looks on the pop-up panel instead of being integrated with the multifunction display into one, continuous all-purpose screen.

You don't have to look at China for the next round of updates, you just have to look at the sister model. They Highlander/Hylander. They are are both made in the same factory in the US on the same line even. I predict the larger newer infotainment, digital instrument panel and TSS 2.5, since that's what the Highlander got for 2023.

The 'upgrades' you saw on the website is already installed on the 2022 ver Chinese Sienna. Not future functions.

I posted some complaints on the Chinese forum to what they can get vs what we can get. They got dual sunroof and the power 2nd row seat, along with power folding side mirrors.

With that said, these functions are only equipped on the top trim, which costs about $85k in Canadian dollars(tax Inc). So...

Many of these updates may still be supply constrained going forward 1 - 1 1/2 years so Toyota may continue to prioritize Highlander and to some extent RAV4 for upgrades. In normal times quite sure the updated infotainment would have been a MY 2023 Sienna feature.

Let's hope some of the current features that have been omitted like DRM come back... let alone more upgrades.

Makes me wonder if power hatch, windshield de-icer, side mirror flashers would have been on our LE if not for supply constraints.

Supply constraints will always an issue as globalization shifting its course. Toyota has two competitive by upgrading its technologies specific to the region and market. In N.A, Sienna is not a luxury van, but a great people mover/cargo carrier/camper and having a great winter package even with the cheapest trim should be a must.

Yes, they couldn't keep up with producing Sienna's or RAV4 Primes (or even regular RAV4 hybrids). So the way I see it, anything new they release is meaningless anyway. The wait on any Sienna is over 1 year in Canada now. If they announce a new Sienna Prime, the wait will be like what, 2 years? That's the wait (at least) for a RAV4 Prime, which means that for all intents and practical purposes, it doesn't exist.

Off topic but related note: We went to look at the Ioniq 5 over the weekend. We were told the wait to get one is approx. 2.5 years.

Here's Lexus' LSS comparison chart, I assume that TSS and LSS are interchangeable

Seems to be a fair extrapolation. Btw, Kia and Hyundai have a new safety system at the top trims of 2023 Kia Telluride and 2023 Hyundai Palisade mirroring TSS 3.0, I imagine Toyota's Enhanced Tracing Assist is similar to Kia/Hyundai's Lane Following Assist (in which the lane centering feature is decoupled from adaptive cruise control function); Toyota's Curve Speed Management is somewhat identical to Kia/Hyundai's NSCC-C with Curve management; and finally Toyota's Left Turn Vehicle Intervention Support, Front to Front oncoming Car detection and Right/Left Turn detection/braking is similar to Kia/Hyundai's FCA JT/LO/LS/JC/ESA. So looks like Toyota and Kia/Hyundai are releasing new versions of their safety system with Kia/Hyundai a bit ahead in the timeline of rolling them out. Unfortunatley, Sienna will be one of the last to receive these systems (don't expect TSS 3.0 in Sienna until at least 2026MY)

What I am waiting for to upgrade my existing 2015 Limited Premium AWD sienna is:
  • Removable second row seats (I actually wish we could get less airbags/grenades in these family haulers).
  • PHEV - Come on its 2023 almost and Toyota can't make the entire line up with a simple plug (even for 110 hook up that would be fine)!
  • I want the new 3.5L Twin Turbo hybrid setup like in the tundra. But the van needs to be able to do 100 miles in EV only mode. Make it so I can buy drop in battery pack modules if that makes it cheaper, but I want 100 miles of battery (its almost 2023).

Optional items I wish to have:
* electro chromatic glass for all glass so we can adjust the privacy/tint level

I think once you start telling customers it’s okay to disconnect the seats which also disconnects the airbags, you open yourself up for lawsuits. Especially when someone clueless removes them and then doesn’t reconnect the airbags. It’s just a can or worms best avoided by saying the seats are not removable.
Removing the seats looks pretty straightforward and is certainly worth while if you go camping or hauling big loads on a regular basis. I just don’t think this applies to 99% of buyers.

That's certainly a possibility, but equally someone may sue for it being "too easy" to remove the supposedly irremovable seats.

Car companies have a lot of experience of dealing with millions of clueless drivers and thousands of predatory lawyers.

Legally speaking, forgetting to reconnect the airbags is not much different from let's say failing to put on your seat belt, or to shut the doors, or even to keep your hands on the steering wheel. The computer will promptly alert you to your great folly, and will continue to do so until you comply, and in certain cases it will even immobilize the vehicle. And the electronic record of the event will be sitting at Toyota's server forever, without your knowledge or consent.

It's not just quality concerns related to the quest for lighter/cheaper materials but it seems there are quite a few electronics issues, not just infotainment, reported here and by other Toyota owners I know of. My experience with earlier Toyotas has been exceptional so maybe my expectations were just unreasonably high.
Same here. Toyota's strongest selling point has been its TCO, the reliability being an important component of it. The Prius was rock solid, but this Sienna quality-wise feels kind of "soft", like the cheapo Accent we had 15 years ago. Runs great as far as the powertrain, but something goes wrong all the time, somewhere in the car.

A cargo version of the Sienna would be very popular for a lot of folks wanting to do light hauling along with smaller, more efficient camper conversions and I'm actually a bit surprised Toyota hasn't cashed in on the current cargo van craze (which is off the charts) and brought something like their Proace van here. It would help eliminate the need to remove perfectly good seating from a Sienna along with not having to either sell or find a place to store such big, bulky items.

I'm more than a bit alarmed at the number of quality issues reported here and elsewhere regarding the new Sienna (plus seeing reports of increased issues with other models) indicating Toyota's legendary reliability seems to have slipped a bit since my (1996 & 2003) Tacoma days. Guess I haven't been paying attention.

Maybe I'm overeacting as I really 'want to want' a Sienna since I feel I could easily make the form-factor work well for me and 30+ mpg in a van is a big deal these days.

Toyota is already struggling to meet demand, a cargo van would just be another model that barely has availability.
I think people are confused about “quality” issues. Toyota has been picking cheaper materials for various parts of the interior but these items have no longevity issues. For example hard plastics are much cheaper than soft touch but they will probably last longer.
