Older Tesla Model S builds to lose connectivity features with 3G network phase out

Published

on

Tesla Model S owners with pre-June 2015 builds of the company’s flagship sedan are set to lose some connectivity features in their vehicle as AT&T is gearing up to shut down its inferior 3G network.

Due to the recent phase-out of older cellular networks like 3G, Tesla Model S vehicles built before June 2015 are still operating with the old MCU chip that cannot connect to LTE networks. AT&T’s decision to shut down the 3G network it has operated since 2004 in February 2022. The company stated that more effective networks, like LTE, 4G, and 5G, offer customers faster speeds. The 3G network is inferior compared to the newer, more advanced cellular networks, and 3G is not needed anymore.

According to Tesla enthusiast Sawyer Merritt, an inside source has indicated that these vehicles without the MCU2 upgrade will lose certain connectivity features when the 3G network is shut down. The only way these features will continue to operate without the MCU2 upgrade is if the vehicle is connected to Wi-Fi.

Merritt indicates that Tesla will be offering retrofits for these vehicles for a bargain price of only $200, even though the vehicles affected by this could be up to nine years old.

Interestingly, Infotainment Upgrades for owners who drive pre-April 2018 versions of the Model S or Model X are eligible to purchase the MCU2 upgrade as well, but it’s available for $2,000 plus tax unless Autopilot Computer 2.0 or 2.5 is installed. For these vehicles, the upgrade is only $1,500.

Infotainment Upgrades are not uncommon for owners of older Tesla vehicles, and we have covered some owner’s experiences in the past. More often than not, the MCU2 upgrade is utilized to gain better performance with smoother instrument cluster commands, access to streaming music and the Tesla Arcade, the added ability to watch YouTube, Netflix, and Hulu, new Driver Assistance features like Driving Visualization, DashCam, and Cellular and WiFi connectivity.

Unfortunately, when MCU2 upgrades occur, owners lose access to AM and FM radio, as well as SiriusXM.

While it is unfortunate some owners of Teslas older vehicles will have to upgrade to keep these connectivity features, it is likely a good thing to have owners operating with MCU2. Because of the chip’s increased capability, owners can experience more features with their cars. At the same time, the upgrade also offers better software performance with more responsive and smoother operation with the touchscreen. Additionally, downtime in the Tesla, like when Supercharging, will now offer more options for entertainment.

Tesla has launched Europe’s first public shuttle service using Full Self-Driving (Supervised) in the rural Eifelkreis Bitburg-Prüm region of Germany, demonstrating how the technology can restore independence and mobility for people who struggle with limited transport options. 

Local officials tested the system on narrow country roads and were impressed by FSD’s smooth, human-like driving, with some calling the service a game-changer for everyday life in areas that are far from urban centers.

Officials see real impact on rural residents

Arzfeld Mayor Johannes Kuhl and District Administrator Andreas Kruppert personally tested the Tesla shuttle service. This allowed them to see just how well FSD navigated winding lanes and rural roads confidently. Kruppert said, “Autonomous driving sounds like science fiction to many, but we simply see here that it works totally well in rural regions too.” Kuhl, for his part, also noted that FSD “feels like a very experienced driver.”

The pilot complements the area’s “Citizen Bus” program, which provides on-demand rides for elderly residents who can no longer drive themselves. Tesla Europe shared a video of a demonstration of the service, highlighting how FSD gives people their freedom back, even in places where public transport is not as prevalent.

What the Ministry for Economic Affairs and Transport says

Rhineland-Palatinate’s Minister Daniela Schmitt supported the project, praising the collaboration that made this “first of its kind in Europe” possible. As per the ministry, the rural rollout for the service shows FSD’s potential beyond major cities, and it delivers tangible benefits like grocery runs, doctor visits, and social connections for isolated residents.

“Reliable and flexible mobility is especially vital in rural areas. With the launch of a shuttle service using self-driving vehicles (FSD supervised) by Tesla in the Eifelkreis Bitburg-Prüm, an innovative pilot project is now getting underway that complements local community bus services. It is the first project of its kind in Europe. 

“The result is a real gain for rural mobility: greater accessibility, more flexibility and tangible benefits for everyday life. A strong signal for innovation, cooperation and future-oriented mobility beyond urban centers,” the ministry wrote in a LinkedIn post

Tesla has posted a new job listing in Shanghai explicitly tied to its Robotaxi program, fueling speculation that the company is preparing to launch its dedicated autonomous ride-hailing service in China. 

As noted in the listing, Tesla China is currently seeking a Low Voltage Electrical Engineer to work on circuit board design for the company’s autonomous vehicles.

Robotaxi-specific role

The listing, which was shared on social media platform X by industry watcher @tslaming, suggested that Tesla China is looking to fill the role urgently. The job listing itself specifically mentions that the person hired for the role will be working on the Low Voltage Hardware team, which would design the circuit boards that would serve as the nervous system of the Robotaxi. 

Key tasks for the role, as indicated in the job listing, include collaboration with PCB layout, firmware, mechanical, program management, and validation teams, among other responsibilities. The role is based in Shanghai.

China Robotaxi launch

China represents a massive potential market for robotaxis, with its dense urban centers and supportive policies in select cities. Tesla has limited permission to roll out FSD in the country, though despite this, its vehicles have been hailed as among the best in the market when it comes to autonomous features. So far, at least, it appears that China supports Tesla’s FSD and Robotaxi rollout.

This was hinted at in November, when Tesla brought the Cybercab to the 8th China International Import Expo (CIIE) in Shanghai, marking the first time that the autonomous two-seater was brought to the Asia-Pacific region. The vehicle, despite not having a release date in China, received a significant amount of interest among the event’s attendees.

Tesla CEO Elon Musk and AI Director Ashok Elluswamy celebrated Christmas Eve by sharing personal experiences with Robotaxi vehicles that had no safety monitor or occupant in the driver’s seat. Musk described the system’s “perfect driving” around Austin, while Elluswamy posted video from the back seat, calling it “an amazing experience.”

The executives’ unoccupied tests hint at the rapid progress of Tesla’s unsupervised Robotaxi efforts.

Elon and Ashok’s firsthand Robotaxi insights

Prior to Musk and the Tesla AI Director’s posts, sightings of unmanned Teslas navigating public roads were widely shared on social media. One such vehicle was spotted in Austin, Texas, which Elon Musk acknowleged by stating that “Testing is underway with no occupants in the car.” 

Based on his Christmas Eve post, Musk seemed to have tested an unmanned Tesla himself. “A Tesla with no safety monitor in the car and me sitting in the passenger seat took me all around Austin on Sunday with perfect driving,” Musk wrote in his post.

Elluswamy responded with a 2-minute video showing himself in the rear of an unmanned Tesla. The video featured the vehicle’s empty front seats, as well as its smooth handling through real-world traffic. He captioned his video with the words, “It’s an amazing experience!”

Towards Unsupervised operations

During an xAI Hackathon earlier this month, Elon Musk mentioned that Tesla owed be removing Safety Monitors from its Robotaxis in Austin in just three weeks. “Unsupervised is pretty much solved at this point. So there will be Tesla Robotaxis operating in Austin with no one in them. Not even anyone in the passenger seat in about three weeks,” he said. Musk echoed similar estimates at the 2025 Annual Shareholder Meeting and the Q3 2025 earnings call.

Considering the insights that were posted Musk and Elluswamy, it does appear that Tesla is working hard towards operating its Robotaxis with no safety monitors. This is quite impressive considering that the service was launched just earlier this year.
