I've always loved our '99 4R for it's LACK of technology that can get screwed up. But I'm not a Luddite either and might be willing to look at a 4Runner with Safety Sense, since this may be the last SUV we buy. Any thoughts on reliability? Last think I want is some computer code that screws up the vehicle, costing money to fix.

I have a 2020. With my experience I have only had audio alerts when it went off but never has it brake for me… that’s because I have it set to the lowest invasive setting. I’m already applying the brake myself when some DUmbass cuts me off and triggers it. I also feel that the truck will function no problem even if the TSS is impaired in anyway… whenever I have frost covering the radar or camera it disables the camera/radar until the frost melts off. Based on that it seems the TSS system will disable itself if it cannot function as intended and your truck will drive just fine as if it never had the system in the first place. I have never had anything odd happen in the 2 years I have had it. My truck is wheeled regularly and even with that jostling around and abuse it hasn’t made my TSS go crazy haywire or anything. I trust these electronics that were assembled in Japan.

Same for me. Audio alert and “BRAKE!!!” displays in the instrument cluster.

Thanks for the feedback - nice rig!

Good to know. Thank you .

Mine works great, I thought I’d hate it, but it seems great so far.

Tip: on my 2022 if I press the cruise control on button for 2 seconds, cruise works with radar disabled.

The only thing I like is the rear traffic alert and blind spot monitoring. Adaptive cruise is really annoying to me and I never use it unless I'm on a long trip.

I used to love Cruise Control on long drives, but there seems to be too much traffic now to be safe to use. The idea that it's adaptive sounds intriguing if it works as advertised.

Sounds like the system works as promised, and if there are problems, it just doesn't work, as opposed to causing other problems?

It works as advertised, but I find it annoyingly slow to speed up after slowing down. Its makes noise inside the cabin which I find annoying as well. So I just stick with regular cruise most of the time since I don't want the vehicle doing any part of the driving for me.

I have always driven underpowered vehicles, so Cruise Control was always slow to accelerate after slowing down ;). I hear you about having the car "drive itself", never felt completely comfortable, but maybe I just need to get used to it by trying it more.

What is the "noise" inside the cabin?

Its a clicking noise when it slows down.

I guess it's one of those "Things that make you go HMMM"

That's all mine has ever done. Is it supposed to do more than that..like apply brakes *before* you hit the wall?

I am sure its reliable as far as not breaking. But Toyota has a long way to go in refinement and non annoying category.
