Tesla software update to address display restarting due to CPU overheating – Not a Tesla App

Ads

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.
Yesterday Twitter held an all-hands meeting with Tesla CEO and Twitter’s potential new owner, Elon Musk.
During the almost hour-long meeting, Elon addressed Twitter employees’ questions and talked about his vision for the future of Twitter.
The video was leaked by Project Veritas and is available below:

You may see headlines state that Teslas were involved in nearly 70 percent of advanced vehicle technology crashes, however this statistic doesn’t paint an accurate picture.
The U.S. Department of Transportation released the initial data it has collected since the agency advised more than 100 automakers to report collisions related to automated driver-assist systems.
Of the 392 crashes submitted to the NHTSA, Tesla had the largest amount of incidents, with Honda coming in second.
Tesla: 273
Honda: 90
Subaru: 10
Other: 19
The other 19 incidents are divided between nine manufacturers.
NHTSA is saying that this data shouldn’t be used to make any conclusions on the safety of these systems.
The data provided by NHTSA lacks context, such as the number of vehicles equipped with the system, the number of miles driven, or how individuals are using the system.
While Tesla has the most incidents, Tesla’s Autopilot is very actively used. Autopilot is likely used more than 3x than Honda’s system, which would instantly change the takeaway people are getting out of this report.
This data also doesn’t show how these systems are preventing accidents. Autopilot is a much more advanced system than those available on other vehicles, so while it was involved in more accidents, it also prevented additional accidents.
Tesla runs Autopilot safety systems passively in the background. It’s ready to hit the brakes or even move out of the way of a vehicle to help avoid an accident.
I’d encourage Tesla to follow up on NHTSA’s report with exact figures of how many vehicles have Autopilot, how many miles have been traveled, and how many times Autopilot has moved within its lane to avoid potential accidents.
The video below shows many of these situations where Autopilot has prevented collisions.

What NHTSA is trying to find out is whether these systems are safe. However, without proper context and additional information, NHTSA is adding confusion about the capabilities of Autopilot.
In a day and age where consumers read headlines and not articles, this report is causing more harm than good.
Due to this report, two senators are now calling on NHTSA to take further action. Senator Ed Markey said, “we are seeing a never-ending parade of reports about Autopilot operating in ways that skirt our safety laws and endanger the public, from rolling through stop signs and phantom breaking. Tesla has argued Autopilot makes us safer, but this report provides further evidence slamming the breaks on those claims.”
This report comes just one week after NHTSA upgraded its probe into Tesla’s Autopilot. The initial investigation started after a dozen crashes involving Teslas and parked emergency vehicles.
In fact, the agency has 35 active crash investigations where Autopilot is believed to have been used. Several news agencies reported they reached out to Tesla but did not receive a comment on the report.
I was lane changing while a motorcyclist very aggressively lane changed and accelerated from behind the car behind me. Autopilot aborted the lane change and was right.
It’s likely the company predicted it would have higher numbers, due to the large number of miles driven with Autopilot.
ADAS, which stands for advanced driver assistance systems, includes driver assistant systems for steering and speed and provides traffic-aware cruise control. Tesla is a frontrunner in this technology and has 830,000 of these vehicles on the road in the U.S. Tesla also has far more advanced crash reports, which is lacking in other automakers.
NHTSA calls this report a first of its kind and plans to release the data monthly. Dr. Steven Cliff, NHTSA’s Administrator, said, “new vehicle technologies have the potential to help prevent crashes, reduce crash severity, and save lives, and the Department is interested in fostering technologies that are proven to do so; collecting this data is an important step in that effort. As we gather more data, NHTSA will be able to better identify any emerging risks or trends and learn more about how these technologies are performing in the real world.”
The report is admittedly not comprehensive. The NHTSA admits it lacked data to provide immediate information from all automakers. It also stated that some companies were more “robust” with data because their vehicles are equipped with telematics (Tesla). In contrast, several other manufacturers do not have telematics capabilities.
