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 comments read like a lot of people don’t quite understand the issue.
The bonnet (hood if you insist) latch may not warn a driver if it isn’t secured correctly. If it is secured correctly then it is fine. So it isn’t going to suddenly open.
If the latch isn’t shut correctly and then the sensor doesn’t report this then the bonnet may open unexpectedly.
If they can use a software update to correct the reporting then that’s it fixed.
There’s no issue with the actual latching mechanism. It’s just the sensor for reporting the latching state.
It may be that it currently works on a two value system. i.e a value for correctly latched and a value for not latched. If that’s the case and isn’t just not providing the second valve correctly then a simple software change to only use the latched value would fix this. As any other value or the absence of a value will report it at unlatched.
The comments read like a lot of people don’t quite understand the issue…There’s no issue with the actual latching mechanism.
…“Although the problem is with the hood latch” <— literally from the article. Care to re-read?
It’s just the sensor for reporting the latching state.
You skipped over the part where a) the latch is deforming, and as a result of that deformation b) the sensor can’t detect that it’s not closed, and so c) Tesla is pushing an update that lets people know their deformed latch isn’t closed properly.
But yes, we all misread the article. Not you. Definitely not you.
And what is the next word after the bit you have quoted?
Is it by any chance switch.
The full quote is deformation of the hood latch switch. Not the hood latch.
Thanks for further confirming my point that you’re not reading it correctly.
No, it’s quite literally not. Click the article, read the article all the way. Including the last paragraph. Where my quote is from.
Then read the recall. Then lookup the part. See what it is? Oh, it’s the entire latch assembly. Good job! Proud of you sweetie. 😘 Keep licking those musky boots!
You missed the part where the latch is deforming, causing it to not close or alert the driver. The software fix is yet another attempt to dodge the fact that they do not have enough repair capacity or financial reserves for a major fleet recall.
Too bad the software isn’t open source.
diff --git a/hood.js b/hood.js
- if(false) {
+ if(true || false) {
+ alert("Check your hood")
It’s a soft close latch, the frunk pulls the lid into the latching mechanism. The mechanism isn’t doing it’s job and needs to be replaced either with a properly adjusted soft close mechanism that grabs the lid, or with a non soft close standard latch that is very obvious to the user when it has not been properly closed.
It’s a bit ambiguous, but I read it as saying it isn’t the mechanism that’s at fault, it’s user error that’s not currently being properly detected.
I don’t think it’s ‘user error’ exactly. Maybe when this has occurred, something in the frunk has obstructed the closing of the hood so it almost latched, but the deformed switch is detecting it as closed. I think they might be adjusting the switch sensitivity in software (maybe it uses a Hall effect sensor and a magnet?) so that this almost-closed condition will be reported as just being open.
