Tesla Issues Physical & OTA Recall for Hardware 4 Computer

Tesla has issued a recall for some vehicles due to issues linked to a revision of the Hardware 4 (HW4) computer that was introduced this past November. This recall affects all vehicles with the revised hardware except for the Cybertruck, as it uses a slightly modified version of the HW4 system.

Many vehicle owners have reported a complete failure of their Autopilot computer, which not only leaves the vehicle without FSD and Autopilot but also disables many of the active safety features that make a Tesla what it is.

Let’s take a look at this recall - because the recall is partially physical and partially a software recall.

HW4 Failure

Tesla has identified the failure and flagged it to the U.S. NHTSA (but not Transport Canada or Euro NCAP at the time of publishing) as a recall.

Tesla mentions that the vehicle’s FSD computer circuit board may short circuit, resulting in the loss of the rearview camera image. The recall itself is focused on the rearview camera - as not having a functional rearview camera breaks a Federal Motor Vehicle Safety Standard. However, it does impact more than just the rearview camera.

As previously mentioned, users have experienced the full loss of Autopilot and FSD on these vehicles, as well as reduced traction control and removal of safety features such as automatic emergency braking, collision avoidance assist, and forward collision warnings.

While the vehicle remains driveable, it is not necessarily a good idea to drive the vehicle with many of these features, especially with the reduced traction control noted by many people. We’ve already noted that while Tesla has been sending tow trucks to pick up some vehicles, it is also prompting owners to drive the vehicle to their service center in some cases.

Remedy

Unlike most of Tesla’s recalls, this one isn’t entirely an OTA recall, owing to the fact that people have already experienced circuit board shorts and are already waiting for replacements.

The software portion of the recall has already been mostly completed for any vehicles with Tesla software update 2024.45.25.3 or greater. However, a significant portion of the tracked fleet remains on update 2024.44.25.2 (approximately 20%), so we recommend updating your HW4 vehicle whenever you receive the notification.

On the hardware side, Tesla is immediately identifying and replacing hardware that has had circuit board failure. Tesla is also reaching out to customers who have expressed intermittent issues with Autopilot features, active safety features, or vehicle cameras that don't display correctly. If you have experienced any of these issues in a late 2024 vehicle, we recommend submitting a service ticket with Tesla to ensure that your vehicle isn’t affected by this recall.

Tesla Says It's Working on a Comprehensive Camera Cleaning Solution

Tesla vehicles rely heavily on external cameras for their advanced driver-assistance systems (ADAS) and the future of fully autonomous robotaxis. However, driving in bad weather presents a significant challenge: keeping those cameras clean. Without a reliable cleaning solution, Robotaxis, which depend entirely on vision, cannot function safely and effectively.

Tesla owner Chuck Cook recently brought up this issue on X, saying to the Tesla AI team, “While I agree cleaning cameras while supervised is definitely something we need to consider... having an official post from @Tesla_AI about cleaning our own cameras is a bit concerning. You have a plan for this, right? Unsupervised can’t have customers wiping cameras.”

The Tesla_AI team responded, “On a more serious note, a more comprehensive cleaning solution is being worked on.”

Front Cameras

With the redesigned 2025 Model Y, Tesla introduced a front-facing camera, joining the Cybertruck in this regard. The Model S and Model X are also slated to receive this upgrade in the future and we eventually expect all Tesla vehicles to come with one standard.

Camera Washers

While the addition of a front camera is a step forward, it introduces another yet camera that needs to be cleaned.

Currently, the Cybertruck is the only known Tesla model equipped with a dedicated camera washer. This system drips water onto the front camera lens, allowing the wind to blow the moisture away. While it’s a simple and effective feature, it’s unclear whether Tesla implemented a similar feature in the new Model Y.

Rear Camera Shield

Tesla recently added a small shield around the rear camera to reduce the amount of dirt and water splashing onto the lens. Additionally, the rear camera on the new Model Y was relocated from above the license plate to the trunk lid. This repositioning presumably helps keep the lens cleaner by reducing its exposure to road spray.

While these adjustments are helpful, they don’t fully solve the issue, especially in harsher environments with constant rain, snow, or road debris.

Potential Solutions

There are several possible ways Tesla could address this issue:

Camera Washers: Expanding the Cybertruck’s washer feature to all external cameras or at least to the rear camera could provide a straightforward solution for keeping lenses clean.
Lens Coatings: Applying special coatings that repel water, dirt, and debris could reduce buildup on camera lenses. However, these coatings would still have limitations in extreme weather conditions.
Software Alerts: Software already notifies drivers when a camera is obstructed or dirty, but this wouldn’t solve the issue without a hardware solution to physically clean the lens.

Given that the new Model Y has already been announced, it doesn’t sound like Tesla incorporated a “comprehensive” solution to the dirty camera issue.

Tesla’s Solution?

Tesla’s mention of working on a “comprehensive cleaning solution” raises questions about what’s in development. The new Model Y doesn’t appear to feature anything we’d classify as comprehensive, and it’s unclear whether it even has a front camera washer like the Cybertruck.

One potential solution could tie into Tesla’s Robotaxi plans. Tesla is building hubs for its Robotaxis, where vehicles can be cleaned and maintained using robotic systems. These cleaning hubs could include robotic arms that wipe down exterior cameras when needed.

While this approach may work for Robotaxis in most situations, it doesn’t address the needs of private Tesla owners who rely on their vehicles daily. Tesla may assume that individual owners can manually clean their cameras as needed.
