Tesla recalls 1.8 million cars because their hoods can open while driving (arstechnica.com)

The electric car manufacturer Tesla had to issue a massive recall this month to fix faulty hood latches that can open while its cars are driving. The problem affects more than 1.8 million cars, which means it's slightly smaller than the recall in December that applied to more than 2 million Teslas.

The problem, according to the official National Highway Traffic Safety Administration's Part 573 safety recall report, affects model year 2021–2024 Model 3s (built between September 21, 2020, and June 2, 2024), model year 2021–2024 Model Ss (built between January 26, 2021, and July 15, 2024), model year 2021–2024 Model Xs (built between August 18, 2021, and July 15, 2024), and model year 2020–2024 Model Ys (built between January 9, 2020, and July 15, 2024).

The problem first became apparent to Tesla in March of this year after complaints about unintended hood opening from Chinese customers. By April, it had identified the problem as deformation of the hood latch switch, "which could prevent the customer from being notified about an open hood state."

Although the problem is with the hood latch, as with many Tesla safety recalls, the problem can be fixed with an over-the-air software patch. The new software is able to detect if the hood is open and, if so, will display a warning to the driver to alert them to stop their vehicle and secure the hood.

Isn't a sensor... A physical part???

Not if it can be fixed with an update, that's a software issue.

But it's not. If you read the article it literally states it's due to not closing because of deformation of the hood latch switch. Which is a physical object. Sure, you can get a notification now that the thing is open, but guess what, if it flops open while driving, I'll probably already know that.

And if you'd read it, you'd notice they specifically say it's the hood latch switch, and not the latch itself, that is deformed. It doesn't pop open on its own, it falsely detects that the hood is properly closed when it actually isn't, so it doesn't warn the driver to go close it before driving off.
There's no need to do a physical recall if Tesla can bodge some other way to detect the hood is still open and tell the driver to close it.
