After two weeks of ownership, yesterday our Model 3 headed up I-15 at 75 mph rapidly slowed to 50 mph for no reason. Lucky that no one was behind us. Is there a fix?

This started happening more with recent updates. It was mostly gone for quite a few versions of the software. I haven't driven enough recently after getting 12.11 to see if it's gone. I know 12.16 is rolling out now...here's to hoping the arguably dangerous behavior, has been resolved.

good luck to you. hope you chime back in with an update. personally skeptical of such a calibration helping but hoping to be proven wrong.As an update to my situation, I sent them dashcam footage and date/time logs so they can review data on the car and they initially told me what I was experiencing was a "feature of autopilot" .. Like WTF? A feature of autopilot is to randomly slam on the brakes when no hazards are nearby? Anyways, we cancelled that appointment, and the next day I went out and recorded the screen and the road with my camera in 4k resolution, in one shot so they could see everything + the dashcam footage, and sure as *sugar* nothing nearby going 85, car slams on the brakes for no reason. Sent the same tech a copy of the video and he said 'yeah we need to send someone out to recalibrate your radar'. tried to tell them 2 weeks ago, not sure why they were so set on not following through with the appointment initially.
They're coming out to recalibrate it next week.
Did the recalibrate fix the problem? I have had the problem of Phantom or panic braking since I got my car last October. They have told me that future software updates would take care of it. I'm still waiting.As an update to my situation, I sent them dashcam footage and date/time logs so they can review data on the car and they initially told me what I was experiencing was a "feature of autopilot" ..

No, there is not a fix, at least not for me. My July 2018 LR RWD EAP/FSD and now HW3.0 Model 3 did not have phantom braking when I first got it on firmware 2018.24.8. The very next update gave it to me in spades, and I have had the annoyance since. It has gotten substantively worse in 2020.12.11.1, my current firmware.After two weeks of ownership, yesterday our Model 3 headed up I-15 at 75 mph rapidly slowed to 50 mph for no reason.

They're scheduled to be out on the 26th. The jacked up thing is they contacted me again yesterday and said the same thing - 'your system looks fine from our side, do you want to cancel the appointment?' no motherfskr I don't want to cancel the appointment, you already did this BS once already.
About all you can do is one or more of the following:
1- submit a verbal bug report each and every time. See the manual on how to do this.
My take: You’re wasting your time. If I were a betting man I’d say there’s a 0% chance any radar calibration resolves this long ongoing issue.
Wanted to post an update with my situation.
Tesla tech came out yesterday to the house took the car out and recalibrated the cameras. I drove it about a hundred miles yesterday to get everything back to normal, didn't see any issues. took it out again today drove another hundred miles on the same road that The braking happens to me all the time on, and had zero incidents. It's still only one day in, but it's the first time I've driven on the interstate for months that it didn't do phantom breaking at least once.
So there's a potential that it actually just needed recalibrated
Disturbing. If it did fix it, that means Tesla designed and programmed a self-driving system that can't tell whether it's safe for the road or not. I hope SpaceX doesn't things differently for the sake of NASA astronauts and their families.
