Tesla is planning to expand its Model Y production lines at the Fremont facility located in Silicon Valley, California.
According to two applications that were spotted on Fremont’s Public Access website, there are several planned advancements of “General Assembly 4.5,” which has been designated for Model Y production at the production facility.
In the past, GA 4.5 was also responsible for the production of the Model 3 sedan in late 2018. GA 4.5 is effectively an outdoor tent that Tesla placed outside of the main building. It currently holds five production lines, with the most recent being installed in September 2019. Tesla planned to expand GA 4.5 in April 2020 but had to find solutions to handle stormwater drainage.
The applications are named “4.5 Expansion Rev 1” and “F20-0048-F DCM2 Arch & MEP.” DCM2 could refer to a second die-cast machine in GA 4.5 that will allow the Model Y to be manufactured with a single-piece casting design.
“The current version of Model Y has basically two big high-pressure die-cast [HPDC] aluminum castings that are joined, and there’s still a bunch of other bits that are attached. Later this year. We’ll transition to the rear underbody being a single-piece casting that also integrates the rear crash rails,” CEO Elon Musk said earlier this year.

It was reported in early June that Tesla was planning to purchase the massive “Giga Press” for Model Y production. But now, the name of the application seems to infer that Tesla is planning to install a second die-cast machine for the Model Y to increase production volume.
Additionally, the F20-0048-F DCM2 Arch & MEP application shows Tesla’s planned expansion of a new “canopy structure” that will connect to the main assembly building.
The expansion is broken down into Mechanical, Process, and Controls.
-
Mechanical
“Process cooling water & natural gas piping distribution design from existing ab utility mains to new casting area outside. Industrial water to serve process equipment. New cooling tower & distribution pump added to existing ab cooling tower yard.”
Process
“Installation of soft water system with distribution piping & accessories. Installation of new compressed air header with filters, distribution & accessories. Installation of new argon and nitrogen distribution with accessories. Installation of new trade waste piping from the tie point inside the building to dcm2 area with pipes, pumps & accessories.”
Controls
“Installation of new sensors on chilled water lines to monitor & control process Installation & networking of new VFD’s to provide control of cooling tower.”
Tesla is preparing for a massive push of the Model Y crossover as demand for the company’s vehicles continues to increase. After delivering 90,650 cars in Q2 2020, the next step is to begin increasing production and delivery figures to sustain growth and increase the consecutive streak of profitable quarters for the electric automaker.
In early June, Musk indicated via email to Fremont employees that the company needed to continue to increase the production of the Model Y by stating that rectifications were to be minimized and that everyone’s effort was appreciated. “I want you to know that it really makes a difference to Tesla right now,” the Tesla frontman said in the email.
After ditching the plans to produce the Standard Range Model Y due to range deficiencies, Tesla can focus on the Long Range and Performance configurations of the vehicle, which have been widely popular within the community thus far.
Tesla’s Long Range and Performance Model Y variants are available for $49,990 and $59,990 respectively.

Tesla has started to deploy the 2026 Summer Update to owners across its fleet, and among the biggest changes are improvements to Navigation, a new startup animation for the Model 3 and Model Y, Caraoke scoring, and new capabilities for Grok.
As the update has started making its way to some cars, we can now see a few of the features operating in real-time. We will show you what some of the new features look like in this article, along with some additional details on what changed.
Not all of the new features in the 2026 Summer Update have quite made an appearance, but some of them have, so we’ll show those here:
New Animation Screen for 3/Y
Tesla is rolling out a new startup animation for Tesla Model 3 and Model Y owners. This is present in Launch Edition and Performance Model 3 and Model Y, but other trim levels do not have anything like this.

Owners can adjust the color associated with the startup animation to suit their preferences. It is a surprise that more automakers do not focus on this animation for their vehicles; it can be a great first impression piece and make the car immediately feel more luxurious.
Tesla has included this on more premium trims, but it is nice to see it on the Model 3 and Model Y.
Grok Improvements
Grok can now adjust more things in the car outside of the Navigation system. Now, drivers can adjust anything from climate to driving settings by simply speaking to the AI assistant in the car:

You don’t even have to push a button, either. Instead, you can just say “Hey, Grok,” if you have it enabled. That feature rolled out with the 2026 Spring Update just a few months back.
-
This is a great feature, especially pertinent for the Robotaxi platform, as there will be no buttons inside the Cybercab when it eventually starts giving rides to the public. It also broadens Grok’s capabilities, which were relatively limited in terms of vehicle setting adjustments beforehand.
Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.

First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.
-
Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
-
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled
— Dan Burkland (@DBurkland) July 27, 2026
Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
