2025 Model 3 Perf FSD issues 14.2.1

pallid7 | 2025-12-09 19:51 | 26 views

Since getting 14.2.1 in my '25 M3P, the car consistenly has hesitation issues when changing lanes on the interstate. Scenario: driving in the middle lane of a 3 lane interstate in Standard mode. When the car wants to pass another car in the, the blinker comes on, the car will start to change lanes (to the left) and will go then hesitate and then eventually make it over. It actually feels like "ok, ok I'm going, then veer back to the center, now i'll ease over". 14.2 never did this -- i drive 120mi daily for my commute. Anyone else experience this issue?

My 2025 M3P did the same at first but hasn't done it lately.

There are probably 5 posts a day since 14.2 came out about this issue. Just need to wait until Tesla fixes it.

14.2.1 sucks. I'm hoping they roll out an update soon. It's a shame we can't rollback to an older version. I've been so frustrated with it.

I am having the same behaviour since 14.2, not better after 14.2.1. Also I notice that on the highway the car is on a constant “mini” zigzagging. I got really disappointed because before the update car was driving like a dream. Super confident and fluid drive. For ref. Model 3 2025 RWD LR.
