There's a lot of conjecture here: Heat battery while braking?
Obviously it's physically possible, you can buy 60kW electric water heaters, but can that much heat be transferred that quickly to the battery?

Yeah, it’s more efficient to coast with limited regen and driver can use brakes as needed.
Yes -- SUA problem is real and not imagined. There are many reported instances and everyone's experience as to when this happens is almost identical. All cannot be pinned as "driver error". I faced the exact same situation, pulling into my garage (May, 2019). I followed up with Tesla and got the EDR data working with my insurance company. EDR data only shows the high RPM and pressure on the accelerator pedal but does not show where the input is coming from. I crashed the car against my garage wall and has not driven it since.
Note how many of these are "New Car" and when Parking.
Your feet have not burned in new muscle memory for the new car yet.
And I also bet most have Creep Off (begging for trouble).

Clearly Tesla needs to add a camera in the footwell.
I do think that creep should be the default setting. Anyone know the normal rate of unintended acceleration accidents?
Some googling estimates 16,000 sudden acceleration accidents a year in the US where it is due to user error, no stats on when it is due to issues with the car. This is compared to about 6 million accidents in general per year (with 3 million injuries, and 30 to 40 thousand fatalities).

I don't have the post/thread link handy, but there's someone on this forum who's willing to lay out a $1,000-and-I-will-testify-at-my-expense bet to anyone willing to let him analyze the car's data after a (n alleged) uncommanded acceleration event, against $1,000 from the person making the claim. According to the last post from that guy I saw, there have been no takers.
Calling @wk057...
Unintended Acceleration is a real problem, and of course everyone's experience is almost identical - when you press down on the accelerator the car accelerates.

Except they already pulled the data and it showed that the accelerator was pressed, but it didn't show who pressed the accelerator. I doubt that @wk057 can prove that!
Might be going out on a limb here, but I'm betting it was the person sitting in the drivers seat...

Hey Guys,
So I was able to retrieve the dash cam data. Here is the link to the video. It is difficult to judge what exactly happened but you can clearly see the acceleration. Also, I thought Tesla had updated the software where if an object is detected in front it will not accelerate so much.

Acceleration occurred exactly where one would normally be pressing the brake. Your brain thought your foot was on the brake but it was actually on the accelerator.
I wouldn't be surprised if obstacle aware acceleration did reduce your acceleration into the car.
I got the ED
Here's a summary of what happened with my Tesla Model 3 car:
1. I turned right (almost 90 deg) from the road, into my driveway and slowed to a halt to park.
2. As I was waiting for the garage door to fully open, the car suddenly and violently accelerated and lurched forward.
3. I immediately jammed the brakes but could not stop before the car hit the wall to my left.
With great persistence, I have followed up with Tesla to get the EDR data and a letter from Tesla (based on their reading of the logs). I have attached both documents. If someone has plausible explanations, I would like to hear more.

According to the data log report, you car wasn’t at a stop when the accelerator was pressed. One plausible explanation is you pushed what you thought was the brake pedal to bring the car to a stop while your garage door opened. But what you actually pressed was the accelerator pedal. If you drive with regen on standard, your foot would have been on the accelerator pedal as you pulled into your driveway, slowing on regen. So a potentially easy mistake to make.
-----------
Two problems with your explanations: 1) The car turned sharply to the left to hit the wall (there would be no reason for me to turn the wheel to the left to go straight into my garage). So even if I pressed the accelerator by mistake (as you claim) I should have gone straight into my garage; 2) I was already stopped -- so there was no need for me to press hard on the brake pedal at that time, although the data shows the accelerator pedal pressed to a peak of 78.8% (BTW Tesla's letter wrongly claims 88%). There are additional inconsistencies between the letter and the log data.
