I've got FSD 12.3 as of this morning, and it is so bad I think something must be broken. I have been using FSD 11.4.9 for months, including two trips to California and back (from Phoenix). Here's what is going wrong.
First, an anomaly in regard to the software download (yesterday), version 2023.44.30.25 replacing 2023.44.30.8 on my 2023 MYP: It downloaded midday yesterday, and oddly the release notes said FSD 11.4.9. The software seemed to install cleanly, and I took it on a quick test drive last night. Still FSD 11.4.9. Today I got up and the release notes say FSD 12.3. Hmm.
OK, so I tried to take a 24 mile round trip from north Phoenix to Carefree to pick up a bag of coffee beans. (A destination I've used before for testing FSD.) The result was utter failure. FSD could not take me to my destination, nor could it take me home again once I got to Carefree. And the reason for that is that it refused to turn - it failed EVERY turn. All FSD would do was to stay in whatever lane I was in at a stop and then go straight.
Here are the problems I had, in order.
1. Autosteer temporarily unavailable. I could not turn on FSD for a mile or so until I got out of my neighborhood and onto a street with painted lines. I noticed several times that FSD would not engage if there were no painted lines on the side of the road.
2. Refused to get into turn lane / would not follow nav. Trying to turn right onto Carefree Highway at 27th Ave, the car refused to get in the turn lane and turn.
3. Never put on a turn signal. Related to the above, I'd say.
4. Refused to get in a turn lane even when I manually put on the signal and the nav was telling me to turn. This seems really weird because the car did change lanes just fine on multiple lane highways when I manually used the turn signals. It only refused to turn at a corner - any corner. Every corner. The last corner on the trip gave me a 'auto lane change unavailable' message.
5. Stops at GREEN lights! Yes, on Carefree Highway, a 55mph rural road, the car repeatedly slowed and STOPPED at green lights. The display showed the lights were green too.
6. Will not proceed from a stop light or a stop sign by itself. ? Every time I was stopped at a light or a stop sign, the car sat there with a message that I needed to use the accelerator or gear stalk (how?) to proceed. When I got it going, it did such slow acceleration that Buicks were going around me.
7. Will not go more than 5 mph over the speed limit. Meh.
8. Very inconsistent behavior coming up to stop lights. Actually, in retrospect it's like the car reversed red and green lights in ways. If the light was green and empty of cars, my car would start 'slowing for traffic control' 500 feet ahead of it. And it was gently brake to a stop - at the GREEN light. However, when coming up to a red light with cars stopped, my car would zoom in at 60mph then jam on the brakes.
9. There were several times where I had to pull the stalk multiple times to get FSD to engage.
The weirdest part is certainly the lack of turning, but in particular when I was coming to a turn with a turn lane and manually put the turn signal on. Not only would the car not get into the turn lane, it fought me and I had to disengage to make a turn.
I'm wondering if my FSD software is all mixed up between 11 and 12. It's completely unusable, unless you never need to turn.
