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.

It’s not the actual latch that’s faulty, but the warning the driver should get, if they haven’t closed the frunk properly.

does tesla just not bother to hire a qa team or something?

[–] [email protected] 6 points 4 months ago (1 children)

It's pretty tough to say without looking at comparable recall rates for other companies. My Toyota Corolla had two recalls that I know about while I owned it, and Toyota is known for their reliability. Tesla is just always in the news because they're always in the news.

Toyota is also known for their reluctance to issue recalls even though they REALLY need to do a recall because they don't want to tarnish their reputation for reliability. Often waiting until the government forces them to issue the recall. I'd much rather the Ford approach and just issue recalls like candy on Halloween. Sure having 700 recalls sucks, but driving a defective car sucks even more.

Cheaper to just let a bunch of people get injured/killed

[–] [email protected] 2 points 4 months ago

Not always. But yes, there is a price.

Microswitch lever fatigue is what this sounds like and it's really not the kind of thing that a QA team could ever detect without years of testing. This is just how it'll go as we add more bells and whistles to all our cars. More obscure new issues will be identified years down the line and added to institutional knowledge for future use.

To be fair, it's not an issue with just Tesla, but basically all modern software. The end user has become the beta tester.

This isn't software, it's a car. It's highly regulated. NHTSA doesn't care if it's a software issue.

Recalls aren’t uncommon. You just don’t hear about most because it’s not trendy.

One of my vehicles is at risk of catching fire. The other is at risk of its axle falling off.

These are major brands, within the past 5 years.

The latch is fault, and so is the sensor. Sensor doesn't go off when the latch starts to fail from deformation.

[–] Lev_Astov 1 points 4 months ago (1 children)

According to the description, it's just the sensor, not the latch. The microswitch has a lever like many do and that lever can become bent if damaged which would prevent it from warning the user if they failed to latch the hood. Most older cars just had a secondary latch so if you failed to latch it completely, at least the secondary one would catch it...

Not sure what description you're talking about, but I'm basing this on the article itself.

Even in your reply..you say the problem is the actual latch being physically damaged.

It's the owner that's faulty for buying one in the first place.

[–] OutsizedWalrus 3 points 4 months ago

I mean, this can happen with any car that has a hinged hood (so nearly all cars)

Is a frunk a front trunk, or is that a typo?

[–] CliveRosfield 9 points 4 months ago

Front trunk, yeah
