Here’s how your Tesla could be affected by AT&T’s 3G network shutdown
AT&T will officially shut down its 3G network today, completing a phase-out of the near-obsolete connectivity as newer, high-speed options are now available. If you own a Model S vehicle built before June 2015, your car may be affected.
AT&T planned to shut down its 3G network as LTE, 4G, and 5G networks offer customers faster speeds. 3G is simply no longer needed. However, customers of other companies who have used AT&T’s 3G network are also affected. This, unfortunately, includes anyone who owns a pre-June 2015 build of the Model S, as its infotainment center needs to be upgraded to be compatible with the newer networks.
In July, Teslarati reported that AT&T’s 3G network shutdown would require a retrofit in any Model S built before June 2015. The retrofit is available for only $200, even though a vehicle affected could be nine years old by this time. 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 vehicles equipping the Autopilot 2.0 or 2.5 computer, the upgrade is only $1,500.
How to know if your Tesla Model S is affected
Tesla encourages owners to check if their vehicles are affected. “Your vehicle will be affected by AT&T’s 3G network shutdown if it is a Model S vehicle built before June 2015 and has not been upgraded to an LTE-capable modem or purchased Infotainment Upgrade, as these vehicles were not produced with a 4G/LTE capable modem.”
“You can also check your vehicle’s cellular network by looking at the connectivity status bars/icon near the top of the touchscreen. If ‘LTE’ is displayed next to this icon at any time (may require stable cellular connectivity), your vehicle will not be affected by AT&T’s 3G network shutdown,” Tesla said.
Owners can schedule the appointment by going to the Tesla Mobile App. Select ‘Schedule Service’ > ‘Upgrades & Accessories’ > ‘LTE Upgrade.’
The upgrade is needed because the Model S built before June 2015 uses a modem that is 3G compatible. New builds contain LTE-compatible modems that will operate with 4G and 5G networks.
Without upgrading, owners will lose the ability to access the following features unless connected to Wi-Fi:
- Roadside assistance to unlock your vehicle remotely
- Certain mobile app capabilities, including Summon, cabin pre-conditioning, vehicle location, remote unlock, etc.
- Certain Infotainment features, including navigation, maps, live traffic updates, up-to-date Supercharger availability and outage information, online music streaming, and onboard map updates
- Over-the-air updates
AT&T told CNN Business in a statement earlier today, “For nearly two years, we’ve proactively sent numerous communications via direct mail, bill messaging, emails and text messages to help customers transition to next-generation networks before 3G services end on February 22.” AT&T has been provided free replacement phones to many users with a 3G device since 2020.
3G networks launched back in 2002 and were an integral part of the growth of cell phones and wireless communications. Eventually, faster speeds were needed and shutting down the 3G networks globally is part of a larger commitment to re-use 4G and 5G infrastructure, which is more efficient than 3G. Verizon and T-Mobile will also deactivate their 3G networks by the end of the year.

Tesla just upgraded its headlights through a software update, making them even better without any physical or hardware upgrade.
Tesla’s latest software update is quietly improving nighttime driving for a small number of owners. Version 2026.38 includes a new capability called Dynamic Headlight Leveling.
The feature automatically adjusts the aim of the low beams in response to driving conditions and nearby traffic, with the goal of giving the driver more usable light on the road while reducing glare for oncoming vehicles and traffic ahead.
2026.38 just dropped.
Model 3 gets Dynamic Headlight Leveling — low beams auto-aim around traffic for max visibility, less glare. Model 3 / Y (AMD HW3) also pick up sharper Tesla visuals + an enhanced park scene on the center display.

Unlike Tesla’s matrix high-beam system, which selectively dims individual LED segments to create shadows around other cars, Dynamic Headlight Leveling physically tilts the low-beam projectors. Internal motors respond to changes in vehicle pitch.
When the car accelerates hard, climbs a steep grade, or carries extra weight in the rear, the headlights can otherwise point higher than intended. The software counters that movement in real time so the beam stays aimed at the road surface rather than into the eyes of other drivers.
Early indications reveal the update is reaching a limited set of vehicles, including certain Model 3 and Cybertruck examples in the United States and the United Arab Emirates. The rollout does not appear tied to a single hardware revision, and Tesla has not published a broader schedule. It is simply a common waiting game until your car receives it.
The change arrives against a backdrop of wider complaints about headlight glare. Some earlier Model 3 and Model Y vehicles were the subject of an NHTSA recall related to excessive low-beam glare; the software adjustment offers a potential mitigation for cars equipped with the necessary leveling hardware. It does not replace adaptive high beams where those are already available, nor does it alter the basic low-beam pattern itself.
Instead, it keeps an existing beam pointed where it is most useful.
For drivers who have received the update, the system requires no new settings or user input. The headlights simply respond as road conditions and traffic change. As the feature reaches more vehicles, it adds another example of Tesla using over-the-air software to refine existing hardware rather than waiting for a new model year. Nighttime visibility and reduced glare for others are the practical results owners are expected to notice first.

Tesla teases “Halloween Mode” update with Optimus rising from a graveyard
Tesla’s Halloween teaser hides a covered vehicle and an Optimus hand rising from the ground.
Tesla has started teasing a Halloween software update for its vehicles, with a short clip on X that reads, “Halloween is coming.” The clip opens on a glowing pumpkin before pulling back to the car’s center touchscreen, where the usual parked visualization has been replaced by a graveyard scene, and the vehicle draped with a white sheet so it reads as a cartoon ghost.

The second detail is a robotic hand clawing its way out of the dirt like a zombie, which looks to be the hand of Tesla’s latest Optimus V3 humanoid robot. While Tesla still has not formally shown Optimus Gen 3 walking around in service, renders pulled from Tesla’s Android app last month gave the clearest look yet, including far more refined hands that Tesla has said carry 22 degrees of freedom. The hand has been the hardest part of the program. Musk has called it the majority of the robot’s engineering difficulty, and Tesla’s patents describe a design driven by tendons with the actuators moved into the forearm.

Optimus also has a Halloween track record. Last October the robot handed out candy in Times Square, and a costumed “zombie” Optimus shuffled around the Tesla Diner in Los Angeles on Halloween night.
On the software side, Tesla’s 2025 Holiday Update expanded Santa Mode with a Santa sleigh, snowmen, snow effects, and a festive lock chime, so it wouldn’t be too far fetched if we saw something similar but themed for a Halloween Mode.
Tesla Full Self-Driving is set to receive improvements to address its two biggest issues, according to a company engineer.
Director of Engineering at Tesla AI, Phil Duan, revealed in a post on X that improvements to both pothole avoidance and navigation “are coming,’ something we have heard many times in the past. However, there are a few things that seem to hint that things might be different this time around.
Improvements on both are coming.

Pothole avoidance, navigation, speed control, and left lane camping are some of the most prevalent and frequently mentioned shortcomings of the Full Self-Driving suite. These are a few of the biggest issues that have kept Tesla Full Self-Driving as a Supervised suite, meaning drivers must remain attentive during operation.
Pothole Avoidance
Pothole avoidance was first mentioned as an “Upcoming Improvement” with the Tesla Full Self-Driving v14.3 update back in early April of this year. It was listed alongside “Expand reasoning to all behaviors beyond destination handling.”
It’s been six months since we first saw pothole avoidance explicitly mentioned, and it has not moved beyond that and joined the main release notes yet.
Tesla has not shed any light on why pothole avoidance has been such an issue for it to solve, but it also has issues identifying large bumps much of the time, so its modeling of sudden changes in road conditions is likely pretty weak at this particular point. I’ve had more issues with large bumps than potholes, personally, but both are issues that need to be resolved.
This is that big bounce that I mentioned in the quoted post.
It’s just a tad too drastic to take at the speed FSD wants to go over it. You can see me quickly swipe down into Sloth, but I intervened. https://t.co/K20PK9ysBg pic.twitter.com/81Oc82ZJcZ

It makes sense that things might be pretty close to being released to the public, as we are going on such an extensive period of time between it being mentioned and it actually being deployed.
Navigation
Navigation is likely the most painful part of using Full Self-Driving, as it routinely takes strange routes, has trouble with local rules (like Except Right Turn Stop Signs in Pennsylvania), and sometimes does not realize that maneuvers it is suggesting are against the law. Turning out of my neighborhood, you cannot turn left, yet my Model Y still suggests it roughly 70 percent of the time when I’m leaving.
However, Tesla might be close to a breakthrough on this. With the Summer Update, Tesla added “Preferred Routes” alongside “Automatic Navigation.”
Preferred Routes prioritized roads that the driver had actually taken before, instead of always defaulting to what the vehicle believes is the most efficient path. This has already solved many of my issues. Formerly, I would turn off the Online Routing setting, and that would eliminate most of my complaints with routing, but then you lose out later on the Live Traffic Visualization.
Tesla’s Navigation has improved tremendously thanks to the Preferred Routes release with the Summer Update, but it still could use some polishing, as it still suggests strange routes from time to time, and it also has a lot of issues getting out of a parking lot. I find that those truly confuse FSD sometimes.
