Tesla Model 3 gets Full Self-Driving HW3 upgrade: Full details with lessons learned

True to Elon Musk’s expectations on Twitter last month, it appears that Tesla is now looking to ramp Hardware 3 retrofits for owners who purchased the Full Self-Driving suite and whose cars are equipped with HW2 or HW2.5. A recent account involving a Tesla owner-enthusiast’s experience with her Model 3’s HW3 upgrade shows that there are still some areas in the retrofit process that can be improved. 

Tesla Model 3 owner-enthusiast TeslaJoy was looking to do a video on the company’s recent voice command update when she noticed that the feature on her vehicle was not working properly. This prompted her to make an appointment with Tesla to get her car checked in and fixed. During the troubleshooting process, she inquired if a possible HW3 retrofit could be done to her vehicle as well. Fortunately, a HW3 unit was available for her Model 3, and so, a rather eventful upgrade process began. 

Tesla Service Centers currently receive batches of HW3 units from the electric car maker, and each unit is assigned to a specific VIN. This is the reason why for now, at least, owners are not advised to call Tesla to schedule a HW3 retrofit. Fortunately for Joy, the Tesla Service Center opted to perform the HW3 upgrade at the same time as her appointment, since she would need to bring her Model 3 back for a retrofit anyway.

Since the retrofit was estimated to take around 5 hours, Tesla asked the Model 3 owner to leave her car for the day and claim it the next business day. That was December 31, which meant that the vehicle should be ready the day after New Year’s. As it would turn out, the Service Center would end up encountering difficulties installing the necessary firmware on Joy’s Model 3. This resulted in delays, which culminated in the vehicle’s HW3 retrofit being completed on January 5, 2020, over five days after the Model 3 owner turned in her car. 

Hardware 3 retrofits are available for owners who have purchased Tesla’s Full Self-Driving suite, and whose cars are still equipped with the company’s HW2 and HW2.5 units. With Hardware 3 installed, owners will be able to utilize the full suite of FSD capabilities that the company is rolling out today. One of these is the FSD preview that Tesla rolled out for the holidays, as well as features like traffic cone recognition. 

True to Elon Musk’s words on Twitter, the HW3 retrofit is free for owners who have purchased the company’s FSD suite. Joy, for her part, was able to get FSD last March at a discounted price of $2,000 on top of her Enhanced Autopilot. FSD currently costs $7,000 when it is included in a new vehicle’s order.

Based on Joy’s experience, it appears that owners should expect to wait some time for their vehicles are set to be retrofitted. In the Model 3 owner’s case, her car’s upgrade ended up taking days since the first HW3 kit that was installed did not function properly. This resulted in the vehicle essentially getting retrofitted twice, causing delays. Tesla did give Joy a $500 Uber voucher due to the absence of loaner vehicles, but the whole experience showed notable points for improvement nonetheless. 

In a way, TeslaJoy‘s experience with her Model 3’s HW3 retrofit stands in stark contrast with the experiences of Model S owner Sofiaan Fraval, whose car was upgraded by a Service Center during a voluntary HEPA replacement. In Fraval’s case, his Model S was fully retrofitted within a matter of hours, and it was calibrated in pretty much the same day. A Tesla Model S owner who runs the Electric Dreams YouTube channel also received his vehicle’s HW3 retrofit without any issues, and it was performed by a mobile technician, not a Service Center. 

In the Electric Dreams host’s case, the entire HW3 retrofit was conducted from the convenience of his home, with a mobile service tech coming over in the morning, taking an hour and a half for the installation to be completed, and an additional two hours for the necessary firmware to be loaded onto the vehicle. This is in line with Elon Musk’s previous statement on Twitter, where he stated that HW3 retrofits should be possible through Tesla’s mobile service fleet. 

Overall, there seems to be a variance with regards to the experience of owners when getting their vehicles retrofitted with Tesla’s FSD computer. Some owners seem to be experiencing a seamless, painless process, while some, like Joy, end up having to test their patience. Hopefully, as Tesla ramps its HW3 retrofits this quarter, the company could work in optimizing its upgrade process, so there are more experiences like the Electric Dreams host’s, and less like TeslaJoy‘s.

Tesla Model Y reclaims elusive sales title in competitive market

As more EVs have entered the market and some at better prices, Tesla’s Model Y has been put up against some very attractive options.

The Tesla Model Y reclaimed an elusive sales title in one of the most competitive markets it is in, outpacing key rivals and formidable competitors to regain the crown it once was a shoe-in for.

As more EVs have entered the market and some at better prices, Tesla’s Model Y has been put up against some very attractive options.

This is especially prudent in Europe and China, where domestic car companies have been offering attractive and cheap EVs as Tesla alternatives.

However, in September, the Model Y was able to battle back and take over the top sales spot for EVs in Europe.

In September, it had 25,938 sales, and although it was an 8.6 percent decrease compared to the same month in 2024, it was enough to be labeled the best-selling car in the European market, Automotive News reported.

500-mile test proves why Tesla Model Y still humiliates rivals in Europe

There are four vehicles that have been atop the European EV sales rankings for any given month this year: the Renault Clio, which has three titles, the Dacia Sandero, which has won four monthly sales titles, and the Volkswagen T-Roc, which was the best-selling car in the market in August.

The Clio captured the number-two spot in September with 20,146 sales.

Despite a strong September showing for the Model Y, which was its first monthly sales crown of the year, the vehicle has not been a top-three EV in Europe this year. That is still led by the Sandero, Clio, and T-Roc.

Despite that, Tesla’s Model Y is still likely to be one of the best-selling vehicles in the world, if not the best, for the year.

In the United States, it has dominated EV sales charts and has been one of the most popular cars in the region. The same goes for China, where the Model Y has more competition than in Europe, but is so attractive because of its premium look and feel, as well as its tech offerings.

The Model Y has been the best-selling car globally for the past two years, outpacing widely popular gas and EV models from around the world.

Tesla also just finished up its best three-month sales period in its history, delivering just shy of half a million vehicles from July to September.

Tesla dashcam video shows crazy plane crash avoidance maneuver

A Tesla captured video of a crashing plane on an Oklahoma highway, as a shocking video shows a small aircraft coming across a local roadway, with various cars ducking to avoid it.

On October 23, an Oklahoma National Guard OA-1K Skyraider II turboprop plane crashed during a training mission after an engine failure. Both crew members escaped unharmed, but they were not the only ones at risk of injury.

A Tesla Dashcam video shared by a friend of the car’s owner shows the vehicle narrowly avoiding an impact with the plane, swerving left, then back onto its side of the road. It appears to be a serious miracle:

David Bellow, the person who posted the video of the Tesla avoiding the plane, claims it was Full Self-Driving that performed the maneuver, but it is not confirmed. This is what he said:

There are a few hints that suggest it could be Tesla’s Full Self-Driving suite, but it is important to note that neither the company, the driver, nor the friend has confirmed this.

The first hint is the vehicle’s maneuver and subsequent reaction. The car suddenly swerves to the left, which any human would do, but how the vehicle continues to travel as if nothing had happened seems to solidify the idea that FSD could have been involved in avoiding the plane.

Nevertheless, this does not confirm that FSD was in control.

My Tesla did this on FSD (Supervised) v14.1 and the internet went crazy

Most people would likely have stopped in their tracks after avoiding an aircraft while driving.

However, this is not enough proof to definitively say FSD was responsible for the avoidance.

Additionally, the “Jump to Event” button is activated in the video, suggesting that FSD was in control. The vehicle gives this option when something major has occurred, including human intervention.

Regardless of whether the car was on FSD or was controlled manually, it is pretty crazy to have this piece of dashcam footage.

Tesla Full Self-Driving got a minor feature that’s a massive improvement

“Brake Confirm for the Start Self-Driving button is now defaulted off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement.”

Tesla’s Full Self-Driving suite seems to get better with every single release. However, it is also making it more seamless and easier than ever to use for passenger travel, thanks to a recent feature that has flown under the radar.

Tesla started rolling out its v14 iteration of the Full Self-Driving suite a few weeks ago to Early Access Program (EAP) members, and it finally started making its way to the public for the first time earlier this week.

Tesla Full Self-Driving v14.1 first impressions: Robotaxi-like features arrive

The wide rollout of Tesla v14.1.3 was long-awaited, as its capabilities were flexed by the handful of people lucky to have it. However, those sitting with v13.2.9 were still eager to get to their hands on the new FSD version, especially considering it came with a lot of cool upgrades.

One of which is flying under the radar and not getting as much attention as it should. Although it is a minor feature change from v13, Tesla has made FSD more seamless than ever with a simple fix that it started utilizing with v14.

With v14.1.1, Tesla started rolling out the removal of the “Brake Confirm” feature, which required drivers to touch the brake to activate Full Self-Driving. This is now an optional feature, as it now is defaulted to the off position by the car.

The release notes for the feature state:

“Brake Confirm for the Start Self-Driving button is now defaulted off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement.

You can enable Brake Confirm in Autopilot > Brake Confirm.”

Simply put, you no longer need to touch the brake to confirm your intention to use Full Self-Driving, which is a small but very effective fix.

It makes your car much more active in terms of overall activation, and it is definitely a quicker and more streamlined departure from your current location than ever before.

Here’s a good look at how quick it is:

@teslarati With Tesla Full Self-Driving v14, there is no delay when you start FSD. Press “Start Self-Driving” and you’re on your way #fyp #viral #tesla #teslafsd #fsdv14 ♬ original sound – TESLARATI

The feature is small, but it is very noticeable with your first uses of FSD v14. Eventually, it will become even more streamlined as Tesla solves self-driving and autonomy, as it will require zero human intervention to get started, which means the “Start Self-Driving” button will also be removed.
