I just bought a 2023 Corolla, and it came with Toyota Safety Sense 3.0. Then, I checked out the 2025 Sienna, and it still has TSS 2.0! Why is Toyota putting the newer safety features on a cheaper model like the Corolla before adding it to a family-oriented vehicle like the Sienna that costs twice as much?
Honestly, it’s probably because Toyota doesn’t want to spend extra on the engineering work to update the Sienna’s wiring or other parts just to add TSS 3.0. They’ll wait for the next model refresh to add the latest version.

Makes sense, but it’s frustrating that Toyota would cut corners on a $40k+ family vehicle.
@Jensen
Well, if it helps, the Sienna is still safer in a car-to-car accident just because it’s a heavier vehicle compared to the Corolla.
@Jensen
True, but in an emergency maneuver situation, that 4500 lb weight could actually make it harder to avoid something in time.
@Jensen
If they didn’t ‘cut corners,’ the Sienna would be $45,000 or more.
@Jensen
They’re already $45k or higher at dealers near me, so it feels like we’re already paying that price.
A lot of it comes down to waiting for a full model refresh. Updating each model as soon as there’s a new Safety Sense version would be way more expensive. The Tacoma was also behind until they refreshed it for 2024.
@Orin
Exactly. I went from a 2019 Corolla to a 2021 Camry and actually got fewer safety features because the Camry’s design was older.
They need test drivers for the new tech, lol 
Honestly, TSS 3.0 can be more annoying than helpful.
TSS 2.0 is already enough. No need for all those extra features.
Did the Corolla get a refresh recently? Price doesn’t always mean you get the latest features. Welcome to how companies operate—they want profit, not just better features.
My new Yaris also has a bunch of safety features. They’re putting them on more of the smaller cars now.
Don’t get too caught up in version numbers. A lot of ‘new’ features are things luxury cars had years ago, like Lexus models from a decade ago.
That’s true, but safety tech has come a long way. I used to drive an older Lexus, and even though it had similar features, they didn’t work as smoothly as they do now on my Corolla.
Headlights are way too bright nowadays. There should be limits—it’s blinding when everyone’s driving around with what feels like stadium lights!
High beams and lane assist aren’t that new; Toyota has been using them for a while. Lexus usually gets them first though.
Yeah, but the high beams on the older Lexus models were almost too dim to be useful, while the new ones work really well in all situations. Technology has definitely improved.
Honestly, TSS 3.0 is a lot better than 2.0 in real use.
