FSD failing after 20 min... Software update bug?

[Coins1 Tx]

Mine has stopped working all the time. Have an appointment on Tuesday to have it checked out as the back speakers have stopped working too.

Every time I head south to Olympia, WA, at 2 specific locations on Hwy 101 near Potlatch the CT always veers over to the centerline rumble strip & I have to intervene.

And then, further south on 101 there is another specific location where the display changes from a 60 mph speed limit to 50 mph even though there is no speed limit sign change at that location.

I’ve stopped reporting these problems now & hope Tesla will soon correct whatever is causing these unique, location based issues to occur.

Keep reporting. I had minor complaint with Model 3, car didn't slow for a rough railroad crossing near the house. Reported it a couple of times and, after software update, car regularly slowed for that crossing.
Software team is fantastic and responsive, like early-days Microsoft. However, speculation is that their attention is on Robo-taxi product at the present time.

I have a 2 hour drive I make regularly, and in one spot, where they shifted the lanes but didn’t move the rumble strips across the road, FSD will scream and disengage. I must pull over, get out and back in to use FSD for the rest of the trip. If I remember to stop FSD before that spot it will throw an error that stop on hold will no longer work that drive. Now I cross my fingers that the country road is empty and I disengage and ‘pass’ the rumble strips if I can. So far with the scream and disengage I’ve been able to figure out what the cause has been with the road surface or terrain. Tunnels, extreme blind hills and odd black marks have all caused them on occasion. I do find it strange I’ve gone over other rumble strips with no bad effect. It appears these in particular make the truck think it’s lost traction or something.

I'll sign on to the lane issues. I've had it drive on the rub strip off the roadway for over 3 miles on an interstate (no traffic) three or four times. Have we written off autosteer out of tesla? I miss it and would gladly give up FSD for autosteer, at least until FSD is fully cooked

Can't get FSD to stay engaged for more than 30 min. Truck (and cameras) are clean, weather is sunny and perfect, traffic light to nonexistent. I'm hoping it's that last software update, it got much worse after it.
Anybody else in FSD hell?

I’m having identical problem. I get twenty or thirty minutes then the red yoke of death. Says ‘cruise control unavailable’. ‘Automatic vehicle hold unavailable’ . And a couple other errors. Do a power down reboot and FSD comes right back on for another half hour or so. I have had a door module replaced, a brake caliper replaced, a full software reload from the dealership, it still happens. I have a service set up for Aug 11- they think it’s a wiring harness failure. Idk, maybe. happened before software update, worse now, but I don’t know if the update is related or not.

Isn't there a way to go into the service menu and revert to the last software version? If there is, I'd do that if the latest software if freaking out.

Not so bad. After turning left onto a two lane road, mine often aligns itself in the left lane-- the oncoming traffic lane!
This truck is my third Tesla and I know how great their FSD can be. I've just assumed it had software issues but, if I'm the only one, it's a hardware problem and I'll have to take it in.

I've had the same issues ... the current version (I don't yet have 2025.6) has a thing with double yellow lines when making left turns. It's about the only steering wheel interventions I've had to make for several thousand miles. Speed control remains sucky -- sometimes 5 under the speed limit, then touch the gas pedal momentarily and it will go 10 over. This is NOT 'keeping up with the surrounding flow of traffic.' Other than these things, it's so good that my wife, who three years ago (2021 Model Y with hardware 3) wouldn't let me use FSD when she was in the car, now 'suggests' I use it in the CT because she's more relaxed when the robot is driving.

There is hope!

Can you get a video of it happening?

Mine does the same on any narrow country road.

Mine was hardware, or was made worse by a hardware issue. It got progressively worse and, I believe, self reported. I had to take it into service. Fortunately, repair only took minutes. Just cleaning the part of the windshield under the center camera cover and, I think, a software update.
That was a month ago and several o.t.a. software updates ago. Since then FSD has, on left turns, lined up left of the yellow centerline twice but only when no cars were oncoming and, when I didn't intervene, it corrected itself in about 20 yards
