Tesla to Patch 130,000 Cars with AMD Ryzen APUs Due to Overheating

[AleksandarK]

One of the electric vehicle driving forces in the car market, Tesla, has today announced that the company would have to issue a soft recall of a few select car models over an issue with overheating. The affected vehicles are Tesla Model 3 2022, Tesla Model S 2021-2022, Tesla Model X 2021-2022, and Tesla Model Y 2022. Tesla's infotainment system is powered by AMD Ryzen APUs, replacing the Intel Atom CPUs found in the previous models. With Ryzen APUs overheating, the infotainment system can lag or restart and sometimes cause it to get completely turned off. The problem is that the car's liquid cooling will prioritize cooling the batteries instead of the processor, causing it to overheat. Tesla issued a soft recall on these models, meaning that a regular firmware update will fix this issue.

Tesla, Inc. (Tesla) is recalling certain 2021-2022 Model S, Model X, and 2022 Model 3 and Model Y vehicles operating certain firmware releases. The infotainment central processing unit (CPU) may overheat during the preparation or process of fast-charging, causing the CPU to lag or restart. A lagging or restarting CPU may prevent the center screen from displaying the rearview camera image, gear selection, windshield visibility control settings, and warning lights, increasing the risk of a crash. Tesla will perform an over-the-air (OTA) software update that will improve CPU temperature management, free of charge. Owner notification letters are expected to be mailed July 1, 2022. Owners may contact Tesla customer service at 1-877-798-3752. Tesla's number for this recall is SB-22-00-009.

Having a moderately "dumb" car is a blessing.

Where does it say in the source that it affects Ryzen?

This isnt normal usage. The 'preparation', doesnt that mean during initial boot up? Bleh, these PRs always play on words.

Tesla goes AMD Ryzen for the 2022 Model Y and Model 3 infotainment systems in America, gets rid of 12V lead-acid batteries

North America is finally getting its new 2022 Tesla Model Y and Model 3 batches with upgraded media system processors and new 12V batteries. Tesla is now equipping all new cars with AMD Ryzen chips instead of the older, slower Intel Atoms, and swapping the 12V lead-acid batteries that were prone...

Tesla has begun to equip the 2022 Model Y and Model 3 models that are rolling off the conveyor belts in the U.S. as we speak with new AMD Ryzen processors and

A car should be dumb car. A car should not have automatic transmission. Everything driver controlled or where is the fun.... and oh by the way, a car should never have anything created by AMD.

I was a bit confused as well since Tesla doesn't usually reveal this stuff (to find out if we had HW3 hardware we had to see if cones would show up in the visualization) but apparently they now do.

Hence, Toms assumed that most 3s and Ys produced in Fremont since then will have new hardware.

Before you hit up a supercharger it needs some amount of battery conditioning. If you set one as your destination, it'll do it on the way there. Allegedly the issue is that the battery is being prioritized on the coolant loop so it does make sense.

Only wires should be the ones to the spark plugs. The rest? Carbs and superchargers! *vrooms in a MOPAR*

Thanks, but what is a supercharger on an electric car? I've only seen them on gas motors.

When you are used to working on cars, cooling priority usually meant going thru the larger hoses first.

also edited in source for AMD info..

It's just Tesla's fast charging network

Supercharger keeps you charged when you’re away from home. With a reliable global network, you can go anywhere and conveniently fast charge. Simply plug in, charge and go.

As for the cooling, it's been a while since I've read up on it and I don't know if 2022s have changed since adding heat pump and Ryzen, but everything just lies on the same (one? two?) loops since these cars really aren't that complicated physically

I was too slow, tabascosauz beat me too it.

Dumb cars last decades. Smart cars will be like smartphones, dying in less than a decade. I don't know why anyone wants what happened to phones to happen to their car.

 

[ARF]

Why? AMD is the superior choice, it is the technology leader.

But, yeah, the tesla inside looks so cheap, simple, minimalistic... and UGLY!!

Right? I'm not doing the smart car thing. No internet or satellite connections, no driver assist crap.

Eh, parking assistance is great. It tells you if the car fits, the angle you need to take, beautiful. Not everyone's a Pythagoras, you know.

Or you can simply avoid that so unpleasant exercise. Don't park between the front end and the rear end of two surrounding cars
Rear view camera and sensor is great, though, to tell you of possible obstacles/walls/etc...

I try to stay equal on all sides.

This sounds better.

Tesla goes AMD Ryzen for the 2022 Model Y and Model 3 infotainment systems in America, gets rid of 12V lead-acid batteries

North America is finally getting its new 2022 Tesla Model Y and Model 3 batches with upgraded media system processors and new 12V batteries.

1st, battery prep is battery conditioning, aka either heating or cooling to get the battery into the ideal temp range.

2nd, that's FUD cuz not all MCU's used Ryzen. There were plenty of Intel MCU delivered in that time frame. It could be true or false, but either way it's inventing facts. Also, the source actually specifies that the cars affected are running certain firmware versions not certain processor types of their MCU.

 

[X71200]

There are some pretty nice non-Tesla EVs out in the market nowadays, the other day I saw an EQC 400 accelerate very good even though the guy wasn't pedalling it all the way. It's a massive SUV even if the battery package is nowhere Tesla-big.

To hell with not having parking sensors if you're parking your car to autistic places, lol. I'm not a bad driver when I drive but those things I'm not doing without.

Would still grab a Genesis G80 EV over these any day, though. Leave Tesla for over glorified hippies.

 

[windwhirl]

... I'll stand by my belief that cars should not have any sort of "infotainment" system at all. Only the information relevant to the act of driving the car should ever be shown to the driver, in a way that doesn't result in a distraction.

 

[X71200]

You just don't look at the infotainment unless you need to. On Infiniti vehicles for example, it tells in your face when you boot the car that you should check the road and not look at infotainment when driving.

You can hack the G37 rear camera to turn it on when you're driving the car, though. Not needed but kind of an interesting bit, heh.

 

[Mysteoa]

APU will overheat, if you don't properly cool it. It wouldn't suddenly behave differently and renders your cooling insufficient.

 

[lexluthermiester]

Eh, parking assistance is great. It tells you if the car fits, the angle you need to take, beautiful.

I've actually tried a BMW with that feature recently. It was pathetic. Got it wrong more than it did it right. I'll stick with actually driving the car myself thank you.

Not everyone's a Pythagoras, you know.

Keep your pedantic, low brow "Chris Rock" like insults to yourself, unless you'd like some "Will Smith" action..

 

[windwhirl]

You just don't look at the infotainment unless you need to.

No touchscreens, either (and quite frankly, no hands-free communications, so no using the phone while driving *at all*).

And if I wanted to truly go all the way to the deep-end, not even music playing or anything like that.

 

[X71200]

Eh, our B8 Audi has got a basic front + back support. Just beeps and shows on display, no extras like on some more modern cars. I guess a luxurious car with both backup camera and sensors could make things a bit more complicated as you have to switch back and forth sometimes, but it doesn't require no Einstein at all.

I never turn music or anything of that form when I'm driving myself, just throw the phone to the pocket and focus on the road. Bad driving habits shouldn't be a reason to ditch modern assisting technologies.
