Here to vent. The adaptive cruise control on my 21MYLR has NEVER worked properly since buying new in Oct 21. From day one it slams on the brakes when passing a semi truck on the interstate. Happened again this morning with my family in the car- Had my own lane to pass the semi, but the car slams on the brakes for NO REASON. Reported it to Tesla service and of course the said a fix is coming- Well, fact is I bought a $57k car TWO YEARS AGO and have never had a properly functioning CRUISE CONTROL. This is so absurd, and I'm tired of giving Tesla the benefit of the doubt on this issue. Give my car a properly functioning cruise control or give me $$$ back on my purchase to account for TWO YEARS of putting up with this dangerous driving behavior.

Done giving Tesla the benefit of the doubt on Autopilot and adaptive cruise control- it's JUNK.

Same vintage car, 9/21 LR Y, same experience. To be fair, there has been 6 months at a time in the PNW when it worked really well. The last 3 updates though have been horrible. Even slightly tighter high speed curves on the freeway lane keeping will drift over the line.
It's back to phantom braking over taking trucks and some other weird times. Still doing ok with mirages, amazingly.
But I'm over it too. Did a 6 hour drive each way a couple weeks ago, no TACC or lanekeeping the whole way, just drove it old school. It was actually really relaxing, and on balance less mental effort than trying to babysit the AP features.
I'm done with all things AP. Actually probably done with Tesla. Once there's an alternative that can use the Supercharging network and charge as fast as Tesla, I'm out. This dumpster fire of a company will never get it right with the current leadership.
Oh, plus all the interior pillar covers keep falling off and never go back on right. Not giving me warm fuzzy feelings, to say the least.

Autopilot & auto steer beta work well for me in my model y built 12/2021. No FSD & I have ultrasonic sensors, no radar. I have it drive by semis & in between. So strange. Y’all know autopilot & autosteer have not been updated in a while for people who do not have FSD.

@OxBrew, I definitely share your sentiments aboutTACC. After 38.6 update it seems more quirky. More slow-downs for no apparent reason. My bigger problem is with the guy at the helm.I test drove an i4 last year and was pretty impressed, but DC charging is too big an obstacle for me. Other manufacturers will catch up, given enough time, and I can envision many Tesla owners making the switch if Tesla continues to not give a damn about its customers and starts fixing some of their glaring software problems. I’ve been a fan of the cars, and they have improved in the 5 years I’ve owned them, but improvements seem to take so long.
This is common, and they are working hard to get this phantom braking under control.
It is getting better and they say they are putting solutions into some of the OTA updates, but people get spooked by it.
They believe the latest AI being populated into the cruise control will eliminate it.
Automated emergency braking is something the Feds recently mandated. Taking some time for the manufacturers to get a handle on it.

I get phantom braking when a "water mirage" occurs on a highway/interstate at high speed. Slams on the brakes at 85 mph if the mirage is too close.
Dash image displays the mirage as a large truck in my lane, hence the braking. Happens both in FSD and ACC. This is not a new phenomenon.
I suspect there is not an easy fix to this.
On rural roads the car tries to change lanes into turning lanes when correct path is straight, this requires a dramatic manual intervention. Car also treats flashing yellow caution lights as full traffic signals - it slows quickly and seems to anticipate a change to red. Poorly striped roads yield poor FSD performance, and rural roads in my area rarely have proper striping. Some FSD stuff is off-the-chart great, but other situations, not so much. Better with every release, but still nowhere near ready for prime time.
YMMV

I'm with you- done with Tesla. Too many promises unkept. And now the "leader" of company doesn't even focus on cars- what made him in the first place.
Auto driving is not an easy problem to solve, for sure. But I very much appreciate the methods and results of OpenPilot (here's the hardware, run our software or someone else's improvement on it, whatever) far more than Tesla (pay now for this story proprietary black box thing that will be awesome someday, right after it stops getting worse!)
Or at least give us a dumb cruise control option on Tesla. That's not too much to ask.

I’m not even asking for auto driving, just a reliable adaptive cruise control where I don’t have to be on high alert. It’s supposed to be a safety system to prevent rear end collisions as well as maintain steady speed, not a video game where you have to be ready at any moment to take control.

Come on be real. Smart summon is blowing everyone's mind just like Elon said it would. We just didn't know it would blow our mind how bad it would it be.

It sounds like you have a direct line to them. Do you have written corroboration for these statements or are you just postulating?

In my quite new 2024 MYLR, I was first shocked at how bad FSDS was. It tried to kill me a couple times. I cannot imagine why anyone would pay for FSD or any of its predecessors. That seems entirely backwards to me. Tesla should pay any of us who want to be test drivers.
My park assist is much less reliable than just using my (old fart) eyes. I kept checking it as I slowly approached the wall in my daily parking spot, and the distance from the wall when the STOP warning comes varies from 6" to 3'. Often, the visual shows the wall and car merged (as if post collision) when the actual separation is 2'.
Lane keeping is scary, several times veering off onto an exit instead of continuing straight ahead.
I found out just after taking delivery that the auto wipers on my car do not work, and have learned here and elsewhere online) that they don't appear to work for anyone.
I have used TACC several times, and is sometimes works ok for about 5 miles. I was beginning to think I could live with just using TACC, and perhaps assign a scroll wheel to make the wipers go immediately to full speed, as required... but even TACC is defective. I have now (in the first two weeks of ownership) experienced phantom braking several times as well as accelerating toward yellow traffic lights.
There must be thousands of Tesla owners who are trying to return cars under the lemon laws. Anyone have experience with that?

I fear it may be too much to ask. My 1973 Citroen SM had wipers that reliably wiped faster as rain increased. Tesla can't even make things work as well as they did 50 years ago.
Who is they? And please explain the process by which the latest AI will be populated into cruise control. Has it already been accomplished? My brand new MYLR does not have TACC that functions correctly, so should I assume that "being populated" is a very very long process? Is it possible that algorithmic programming might be a better choice? It seems that the things that work well on my car (its being able to produce a fart sound, for example) can be easily accomplished via conventional algorithms.
Wall Street (maybe due to a short squeeze) seems bamboozled by this news: https://www.cnbc.com/2024/04/29/tes...assing-hurdle-to-china-full-self-driving.html. Sure, they'll have a new source of revenue now (didn't realize that "FSD" didn't exist there) and it's the world's largest auto market w/a strong EV market but stock jumping 15%?
BTW parsec, you might find this take amusing: Robotaxi? Really??.

Curious to know what issues you have with TACC. I have very little to complain about with mine. The unexpected braking thing is now a rare occurrence
Unexpected braking occurs about twice a day on my 12 mile commute. Most frequently, I think, around over/under passes, but elsewhere too. Following distance is often handled well, but occasionally the response to coming up to a slower moving vehicle is delayed, so my MY tailgates a little before establishing a safe following distance.
A few days ago, it accelerated upon seeing a yellow light.
