The conspiracy theorist in me says this came at a time when the US auto market wasn't great and it was amplified to get people to buy American cars.
In fact the evidence looks just like this situation with the Cybertruck. So getting back to the confirmation of priors point: it's telling that you view one as a "conspiracy" and the other as The Truth.
The floor mats were blamed, but in at least a couple of these cases, it was found that the occupant claimed to have hit the brakes, but actually hit the accelerator.
There is also a staggering number of “two foot drivers” out there.
Incidentally, my sunfire also had the issue of the pedal getting stuck on the floor mat, and more than once I had to press in the clutch cause the pedal got stuck.
The focus on toyota those years always stood out as a hit job to me (and that was a time when I generally disliked Japanese cars cause I was young and impressionable).
You're saying that it may not have been the cause of an accident. Which may be true, but (1) isn't evidence that there wasn't a clear design flaw and (2) is also true of the Cybertruck, which hasn't had any reported mishaps at all.
Yet to you the Toyota thing was a "hit job" where this isn't? It's 100% symmetric, so why the difference in interpretation? I mean, we know why. But "because Elon" makes for poor logic.
The mats were a hit job because most of the cases were not actually the mats, and one company was getting a hard focus for this issue when it was prevalent in many different brands.
The cybertruck is not a hit job because this is just another in the laughing stock line of quality control and design issues from a company known for it.
I don't see Porsche's, Hellcat's, and BMW's having issues with something that has been a resolved non-issue for decades at this point.
I too "find it within the realm of acceptable that a $30,000 car would have issues that should absolutely not be present on a $100,000 car". If, say, a plastic piece on the dashboard tends to develop an unsightly crack over time, that's more ok for a $30k car than for a $100k car.
But some design issues should be present on no car; not a $30k car, not a $100k car, not a $5k car. "The car sometimes accelerates on its own" is one of these.
And I will preface this by saying that Audi isn't without fault either, but my also $100Kish RS 5 has in two years had two issues: a battery failure (determined to be a battery fault, not a vehicle fault), and improper drainage in one of the doors, leading to an accumulation of water, that had a tech advisory to add an additional drainage hole.
Looks like they've recalled almost 1 million vehicles and have tried multiple times to address the issue.

I don't know enough if that meets your requirement of "something that has been a resolved non-issue for decades at this point" but it's something that BMW has apparently been trying and failing to fix for awhile now.
I have higher expectations for my poorly made death machines.
