Tesla to address display restarting in certain situations
Tesla has issued a new recall affecting 129,960 vehicles from 2021 and 2022, due to an overheating issue with the
infotainment center CPU.
The automaker has discovered a fault where the center display may become laggy due to the CPU overheating when
the vehicle is pre-conditioning the battery pack for Supercharging or while it's Supercharging.
“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
wrote in their recall notice.
Tesla claims to have discovered the issue during standard endurance testing. Although there have been no reports
of wrecks or injuries, the company has received 59 warranty claims from January to early May.
Luckily, just like past recalls, the automaker will be able to fix the issue with a software update. The Recall
Report from the National Highway Traffic Safety Administration Safety reads:
“On May 3, 2022, Tesla began deploying an OTA firmware that will improve the management of the CPU temperature
and associated communications with elevated temperature operation. This remedy will mitigate temperature
elevations in the CPU when the vehicle is fast-charging or preparing to fast-charge, which will prevent slow
processing or restart.”
Tesla will contact the specific owners with an official recall notice, expected to be mailed July 1, 2022.
Tesla’s ability to issue over-the-air software updates in order to fix most of the issues that have led to
official safety recalls lately, highlights the effectiveness of their approach to in-car operating systems and
connectivity, a feature that seems to be gaining fast adoption by other automakers, and will surely change the
landscape of the automotive industry.
A typical traditional recall, in which affected owners must bring their vehicles in for service, could easily
bankrupt a carmaker, which must pay for labor and parts to perform the repairs.
Affected vehicles appear to be limited to those with Ryzen-based CPUs, Tesla's latest MCU. MCU 3 provides increased
responsiveness and faster loading apps such as streaming services and the web browser.
If you have a Tesla with a Ryzen-based
CPU and have experienced a delay when using the touchscreen or had it restart randomly, you may see
improvements when this fix is rolled out.
The fix is expected to be in later revisions of Tesla's 2022.12 updates.

Tesla is getting ready to start rolling out FSD support for hardware 3 vehicles in China. Tesla is internally testing what appears to be a build of FSD V12.6 on HW3 vehicles with its employees.
A post on Chinese social media platform Rednote initially shared the software update details and was then shared by Tesla Newswire. We’ve verified that the vehicle in question is a 2023 Model Y, confirming it falls within the HW3 hardware generation.
We reviewed FSD V12.6 in depth here, and provided a comparison to FSD V13 here, but here’s the key points you’ll need to know.
FSD V12.6 is Tesla’s latest revision of FSD for HW3 vehicles and it’s is very comparable to FSD V13 in terms of features. It includes 3 speed profiles, Chill, Standard, and Hurry, which control how aggressive FSD is in making lane changes and ensuring it stays at, near, or above the speed limit.
This version of FSD also comes with an improved controller, as well as earlier and more natural lane change decisions, making it far more capable than V12.5 or V12.3 builds.
For Chinese customers getting their first taste of FSD after using Autopilot for years, it’s mindblowing. It can handle city level streets, hanlde turns and traffic control signs and get you to your destination with minimal interventions.
When Does It Release?
Given’s China’s more crowded streets and more complex road layouts, we weren’t sure whether Tesla would introduce support for HW3 vehicles in the market. This news is a positive and encouraging sign, not only for FSD in China, but for all HW3 vehicle owners out there.
Tesla usually releases updates to employees in advance of releasing them to its general customers - providing them with a second chance to find and fix bugs. Usually, once updates make their way to employee vehicles, and barring any major issues, they begin rolling out to customers within one to two weeks.
China currently requires owners to buy FSD, as FSD subscriptions aren’t available in the country yet. If you’re in China and bought FSD on a HW3 vehicle, it may not be long before you have access to FSD.
Tesla’s Cybertruck has officially earned a 5-Star Safety Rating from the NHTSA—an impressive achievement given the vehicle’s design. The achievement demonstrates Tesla’s engineering prowess. As one engineer points out, it wasn’t an easy feat.
Interestingly, the NHTSA only recently disclosed the results, despite the crash tests being completed a while ago. According to Lars Moravy, Tesla’s VP of Vehicle Engineering, the team had been aware of the 5-star rating for quite some time. While the reason for the delay remains unclear, now that the results are public, Tesla’s engineers can finally share how they achieved the rating.
Crumple Zones
Wes Morril, the Cybertruck’s Lead Engineer, wrote about the crash test video on X recently, addressing the claims that the Cybertruck doesn’t have a crumple zone. He also posted a side-by-side video (below) of the engineering analysis and the crash test itself.
Engineered Crash Safety
There’s a lot of engineering precision at play when a Cybertruck is involved in a crash. Unlike traditional crash structures that rely on crash cans and collapse points, the Cybertruck’s front gigacasting is designed to absorb and redirect impact forces in a highly controlled manner.
It all starts with the bumper beam, which crushes within the first few milliseconds of a high-speed impact. At the same time, the vehicle’s sensors rapidly analyze the crash dynamics and determine the optimal deployment of safety restraints, including airbags and seat belt pre-tensioners. These split-second actions are crucial in keeping occupants safe.
As the crash progresses, the vehicle’s structure deforms in a carefully engineered sequence. The drive unit cradle bends, directing the solid drive unit downward and out of the way, allowing the gigacasting to begin absorbing impact forces.
The casting crushes cell by cell, methodically dissipating energy in a controlled manner. This gradual deceleration reduces the g-forces transferred to occupants, making the crash much less severe. As the gigacast begins crushing, the safety restraints are deployed.
As Wes points out in his post - you can see how accurate the virtual analysis and modeling were. The video shows the simulated crash side by side with the real-life crash test and they’re almost identical. All that virtual testing helps provide feedback into the loop to design a better and safer system - one that is uniquely different than any other vehicle on the road.
All the armchair experts claimed the Cybertruck has no crumple zone and I get it, the proportions seem impossible. It was a tough one and there is a lot of engineering that went into it. Let me break it down for you:
