    FSD The latest disaster

    I've been testing FSD since Jan 2022. The software improved from Jan 2022 to approx Nov 2022. Since then, it's been one disaster after another, often the newer release fixed a problem created by the prior release. The latest is no exception. Here's a summary of the latest disasters...

    Autopilot was about to kill me

    First, I am sorry about the clickbait title. I am a proud owner of a new model X (decided to take advantage of FSD transfer option). To give you some background - I've been an FSD beta tester since it was available (after a strenuous couple of weeks and a 99 safety score) for couple of years...

    Car slowing unnecessarily for slower cars in adjacent lane on EAP for anyone else?

    For several months now, when in bumper-to-bumper traffic, if my lane (usually the HOV lane, to the far left) is moving faster than the traffic in the lane to my right, my car, while on EAP, will suddenly lock onto one of the cars in the lane to the right and slow down as if it's actually in my...

    I saw the phantom

    I was in my 2018 S 100D a few months ago, cruising from Paso Robles to I-5 on what's known as the "James Dean Memorial" highway. There was a long stretch of straight road, cutting through the central valley heading east, no traffic in sight, and the car started braking. I glanced at the...

    FSD Owners - Do any of you prefer leaving it off?

    I own FSD. My opinion is FSD drives like an erratic teenager first time driver. Sometimes it's so slow it annoys you. Other times it leaves so little distance it scares you. It's jerky and not smooth. It automatically does lane changes on its own which I'd rather leave off and initiate myself...

    Tesla FSD - A Five Year Perspective

    My Model 3 was delivered in mid-August 2018. While I originally just had Enhanced Autopilot (EAP), I quickly paid the extra $2000 to get FSD as rumors swirled about Tesla charging more in the future. What's my opinion after 5 years of testing and playing with Tesla EAP and FSD? TLDR: It's pretty...

    FSD 11.4.4 - stalling in the middle of a turn

    Here's the issue I observed 2 times over past 24 hours. Notably, this happened at the intersections that weren't previously seen as problematic. When making an unprotected left or right turn, FSD waits, commits to the turn and proceeds but then violently jerks steering wheel left/right and then...

    FSD beta - first time user reactions

    I have got to be honest. Full Self Drive capability in Tesla goes further than any other vehicle designed by man (or woman) but it left me wanting for more. I bought my Model Y Long Range on Friday 9/1 and took it for a little ride from Houston to Corpus Christi on Sunday 9/3. Here are my first...

    Is it worth reporting bugs?

    I still report bugs, particularly phantom braking, by hitting voice assistant and saying "Bug report: phantom braking" and it goes through. Is it even worth doing that? In this age of AI learning everything, does reporting like this even do anything?

    Do any HW4 Vehicles have FSD Beta activated ?

    I traded in my 2022 Model x - that had FSD Beta activated for a 2023 Model X Plaid - with HW4. Sort of disappointed that I went from a working FSD beta vehicle to one that is "waiting for a future update". Help me understand, have any HW4 vehicles had their FSD Beta activated? Does anyone...

    AP phantom deceleration? Not Braking

    This has been going on in my 3 for a month or more now across 2 software updates. Multiple times on my 10 mile commute, using autopilot, it will randomly just stop accelerating. Sometimes it happens while going through an intersection, sometimes not. I've tested it in the early morning on...

    Tesla Software Irritations

    Hi everyone, I'm new to this forum and am hoping to be able to learn more about my Model Y and - in particular - some tips of optimal configuration of the software. Given I'm in Australia (Sydney), my experiences might be a little different from others, but I'd appreciate any thoughts people...

    Why is AP dropping 20mph on freeway

    About a month into ownership here. On the last few trips with AP; going home during rush hour in the HOV lane with a wall of cars to the right while cruising at 75mph the car will randomly drop into the 50s. I can’t figure out why but it brakes pretty hard. I’m sure the pile of cars behind me...

    Could bugs be causing (some) phantom braking?

    I live in Portland and often drive south on I-5 to visit my folks in southern Oregon - I have never had a phantom braking issue. My wife takes the X on a trip to Boise through eastern oregon and reports half a dozen phantom braking issues. Weird. We then went together this past weekend on same...

    Phantom Braking getting worse - any ideas on how to stop it?

    Just took a trip from Texas to Arizona on I-10 in my 2020 LR M3. From West TX to middle of AZ had about 15 instances of phantom braking. HARD braking - from 80 mph to 25 mph in seconds. Thankfully no traffic behind me or they could have easily hit me from the drastic slowdown. Had previously had...

    FSD beta Constantly Moving out of the Cruising Lane

    Did a 4 hour round trip drive yesterday and I have to say that I hate how the FSD beta doesn't have an option to stop Auto lane changes because it constantly wanted to go from the highway cruising lane into the passing lane when no one was in front of me. It must have done it about 20 times...

    Has Basic Autopilot improved (and phantom braking decreased) since radar was removed? (About to buy!)

    Hey guys I'm taking delivery of my new Model 3 on Friday... but I've been a bit spooked reading various articles about the removal of radar in 2021 (2022 in our market - Australia), and the deactivation of radars on cars which do have them. I've had a Mazda CX-5 until now, and while the auto...

    Latest FSD Beta update is a step backwards

    I have a 2020 Model X and was an FSD Beta "test driver" for several months. I downloaded the latest FSD Beta update - presumably the one that serves as the "recall" required by NHTSA - two weeks ago. Since then, my car continues to make the same mistakes it was making under the previous...

    Phantom braking at night with 2022.44.11

    I've had 2022.44.11 for three days now, and for the first time since receiving it, I did a 45-minute drive after dark. (It actually began at late dusk, and by the end it was completely dark.) This drive was mostly on the highway, and phantom braking was awful. I experienced it probably about a...

    Has anyone heard of a Tesla being rear ended because of phantom braking?

    Phantom braking is unsettling and seems like it could cause a rear ending incident but I've yet to hear of a single case where this has happened. Out of the millions of miles that Teslas have driven with automation, there should be multiple reports of accidents if this were truly a problem...

    Why are TACC, AP (and ?FSD) so bad?

    Just recently took another long drive in my 2022 Model S LR and tried out TACC and AP again. (I didn't purchase FSD since it's not ready for prime time). Still serious problems: - Multiple phantom braking episodes on deserted straight roads (single and double lane) - Multiple "Collision warning"...

    Do you regret updating to use Tesla Vision and disabling your radar? Would you go back if you can?

    My M3 is still on 2022.20.X - I stopped updating ~4 months ago when they turned off the radar in favour of Tesla Vision. Everyone on here and the subreddit was saying how phantom braking is worse, which I didn't really like, but the real dealbreaker for me was requiring the auto high beams...

    Why I am losing faith in Tesla’s Autopilot (Autosteer)

    I absolutely love my Model 3. I have had it for just over 3 years now and enjoyed driving every mile of the 42,000 miles that I have clocked till today. Most of the mileage has been on the highway and the remainder was miles that I racked up while commuting for work before the pandemic. When I...

    Major Phantom Braking Issues

    Hi guys, Just wanted to share an experience that I've had today so that others looking at Teslas to use for long distance driving can make an informed decision. My wife and I drove our 2023 MYLR from Tucson to Las Vegas. It's a ~7 hour drive (8.5 with charging stops, ~400 miles) mostly...

    Anyone else having trouble with Traffic-Aware Cruise Control?

    I'm currently driving across Canada in light winter conditions and have had to fight with cruise control a lot more than I'd like. When you activate cruise control you are also engaging Autopilot even if you don't have the Full Self Driving package. And because Autopilot depends on the car's...

    Subscribed to FSD, Very disappointed...

    So, I know this isn't the FSD Beta, but if there is a trickle down of software to the features that were available, I am incredibly disappointed. I just took a 1000 mile trip and there are so many errors and bugs that I just preferred to turn off NoAP and drive on my own. List of things I...

    Nervous Nelly [FSD Complaint]

    FSD and Phantom Braking on the Highway. It is Insane.

    Since I got FSD beta and Tesla switched to a "vision only" system I have been having several random braking whether driving on interstate or state highways (2018 Model S). This happens noticeably when driving with no one in front of me. It has made highway travel an annoyance while having AP...

    Today I experienced phantom braking with Beta when vehicles come up behind to pass. This is dangerous as a closely following vehicle hardly expects the vehicle in front to suddenly slow down. I've read of phantom braking in other scenarios, but not from passing vehicles. Anyone else experience...

    Phantom Braking Needs to be Reported and Fixed

    Yeah, it's bad. I'll be cruising along at 70 mph and my Model Y sees a yellow caution sign with flashing lights and hits the brakes. I push the camera icon to report each incident. Not sure how much that helps, if at all.

    Phantom Braking vs TACC in Late 2020

    On the cusp of getting a new car, and there is so much about the Tesla Model 3 that I love. The one thing I'm worried about is phantom braking during TACC (not talking steering assist, nor FSD). I've been doing a little digging... OK a lot of digging, and it is clear that with each software...

    Reduce/eliminate phantom braking (trigger warning)

    Some weeks ago I posted a poll on how often people experience phantom braking, and the results were around 50% for "Almost never" and the rest spread out over "seldom" to "almost always". That's a really high number so I decided to test out different strategies to improve it (I was one of the...

    My 100D model S regularly brakes hard for no reason at all when in FSD. Have others noticed this?

    For the past few weeks I've noticed extremely erratic braking when in FSD. The car is going along just fine and it will all of a sudden, for no reason at all, slam the brakes and slow down roughly 15-20 mph. It is dangerous and has almost caused an accident twice

    How often do you experience phantom braking

    I think most people on this forum has experienced phantom braking. Some think it's no problem, others think it's a crime against humanity. Personally I think it's such an awful experience that I don't use TACC or AP any more. Every once in a while I use it while I open a bottle or put on my...

    Increased AP1 phantom braking lately

    During few weeks lately i’ve noticed increased phantom braking in my 2015 AP1 Model S. Normally phantom braking is rare, but during last few weeks I’ve had many. Perhaps it is because of piles of snow on road shoulders. We have got a lot of snow during last few weeks. AP1 has whitelist of...
