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.

    The problem is with a shitty latch: the hood appears closed, but it’s not.

    The OTA Update doesn’t fix the shitty mechanical latch - it still doesn’t latch consistently. What it fixes is another poor design choice: evidently, the car has sensors that can tell if the hood was closed correctly or not, but this was never turned on/programmed? The OTA Updates this so now the car can warn you when the shitty latch fails.

    Or who knows, maybe they initially turned off that sensor because it was going off all the time because of the latch…
