In the latest episode of the Ride the Lightning podcast, Tesla’s VP of Engineering, Lars Moravy, addressed a question that’s been on everyone’s mind—what’s going on with the Model S and Model X?

It turns out Tesla’s engineering and design teams have been thinking about the same thing. They’ve heard the calls for a refresh loud and clear, and changes are on the way to Tesla’s flagship vehicles.

Most importantly, Lars put the rumors to rest—Tesla has no plans to discontinue the Model S and Model X. Not only are they here to stay, but a refresh is also in the works.

Just give it a minute, we’ll get there - Lars Moravy

Refreshed Flagships

According to Lars, the Model S and Model X will finally be getting some attention—but not until later this year. For now, Tesla’s top priority is launching its more affordable next-generation vehicle ahead of Q2 2025.

Still, a refresh is on the way, and many of the upgrades seen in the Model 3 and Model Y refreshes are expected to make their way to Tesla’s flagship vehicles. There’s a lot to break down from that simple statement, so let’s dive into what’s likely coming—and what we’re hopeful to see.

Interior Updates

Both flagship vehicles are expected to receive a Cybertruck-inspired update—though not in the form of sharp angles and stainless steel. Instead, Tesla, we may see many Cybertruck features move over to the Model S and Model X. We may see things like the removal of the driver’s gauge cluster display in favor of a larger center screen, similar to the Cybertruck’s design. Unlike the Model 3 and Model Y refreshes, this screen won’t tilt, simplifying production and increasing part-sharing across the Model S, Model X, and Cybertruck.

These changes streamline Tesla’s supply chain while also making the vehicles easier to repair and service. However, it’s not all about cutting features. Last year, rumors suggested the Model S and Model X would receive a mid-cycle interior refresh, including ambient lighting—now a standard feature across Tesla’s lineup. This subtle yet elegant lighting improves the cabin’s aesthetics without being overly bright or distracting.

Another major update will likely be the transition to a 48V low-voltage electrical system, a move Tesla has already made with the Cybertruck. Tesla recently announced that a lot of the Cybertruck’s tech, such as this 48V LV system, its 800-volt HV architecture, bi-directional charging, and more are coming to future Tesla vehicles.

This upgrade could also bring support for steer-by-wire to the Model S/X, which would greatly improve the usability of the yoke steering wheel.

Exterior Updates

When it comes to exterior changes, we’re a little less sure of what to expect. A complete body makeover is very unlikely, but we could see updates to the front and rear fascias like we’re seeing with the new Model Y. We hope Tesla preserves the iconic design of the Model S. Its sleek, aggressive profile has a broad appeal—even among muscle car enthusiasts who appreciate its sharp lines and commanding presence.

For the Model X, Tesla might follow a similar strategy to the Model Y refresh, further differentiating it from the Model S. We could also see the introduction of a light or rear light bar like we’ve seen recently with the Cybertruck, new Model Y, and the Cybercab. Tesla has really perfected its grill-less look with recent models and we may see that carry over to the revamped Model S and Model X as well.

FSD Hardware Changes

The timing of the refreshed Model S and Model X could overlap with the launch of Tesla’s next-gen FSD hardware, AI5. While this would be unexpected—given that Tesla has yet to fully utilize AI4—it could align with Musk’s June 2024 statement that AI5 would be available in about 18 months. Afterall, the Cybercab will include AI5 when it hits production this summer.

Additionally, like the recently refreshed Model Y, the Model S and Model X have long been rumored to receive a front bumper camera, and this update will likely bring it. In turn, Tesla may remove the HD radar that has been shipping—albeit disabled—with every Model S and Model X. While the radar appeared to be included for data collection purposes, Tesla never fully committed to integrating it into its autonomy stack.

Drivetrain and Battery

The Model S and Model X still use a relatively outdated air suspension system. If you own one, you’re probably familiar with the issue: the camber (angle of the wheels) changes depending on the vehicle’s height, which increases wear on the inner or outer edges of the tires. Combined with the vehicles’ immense acceleration, this can lead to increased tire wear.

With the Cybertruck’s updated air suspension, this is considerably less of an issue due to how the new suspension functions. It would make sense for Tesla to integrate similar improvements, along with other updates to improve handling, much like the changes made to the refreshed Model 3 Performance. Track Mode V3 would also be a welcome addition to both Plaid models.

Additionally, adopting the Cybertruck’s 800V high-voltage architecture could enable the new Model S and Model X to charge faster, potentially reaching the 500kW speeds the Cybertruck will soon support at V4 Superchargers.

New Production Lines

There’s also another interesting tidbit circulating from stock analyst M44_1RJ. It’s rumored that the Model S and Model X production lines, known internally as the GA1 lines at Fremont, are undergoing upgrades. These improvements are likely part of Tesla’s preparations for the upcoming refreshed versions of these vehicles.

We’re eager to see what Tesla has in store for the refreshed Model S and Model X. While we could see completely new features added to these flagship vehicles, we’re more likely to see some of the Cybertruck improvements carry over.

There’s even hope that the Plaid+ variant will make a return to the Model S, providing a sleek and worthy competitor to the Lucid Air Sapphire and other electric hypercars making waves on tracks worldwide.

It seems Tesla has something big in the works, but it’s probably at least six months away. We can expect more tangible updates to surface around late summer, likely after the launch of the Cybercab and Tesla’s more affordable model.

Tesla May Add Lumbar Support to Driver Profiles, Offer Turn Signal Stalk Retrofit

By Karan Singh

Tesla’s Vice President of Vehicle Engineering, Lars Moravy, recently took to X and opened the floor for user input. There, he asked the community for features and improvements they’d like to see to make Teslas better heading into 2026.

This post generated thousands of suggestions - and we recapped the best of them. There were also a few that Lars responded to, giving owners hope for some much-requested future changes, so let’s take a look at what may be coming

Lumbar Profile Support

Today, lumbar support is one of the few items that is not saved in the Tesla profile. That means if you have multiple drivers who use the same vehicle, you’re often left adjusting this setting manually, as it retains the setting that was last used. One community member suggested saving your lumbar setting to your profile just like Tesla does for other seat settings.

Lars said making this change seems doable, but it’ll take some engineering magic. The lumbar support isn’t tied to an absolute sensor like the other seat settings. This suggests that Tesla does not have an exact value to save, as it does with other seat functions, but Lars believes Tesla can find a way to save lumbar preferences. Tesla could potentially time how long the motor runs to get to the user’s lumbar setting and save this value.

With that said, it seems the vehicle engineering team may take a look at this one, and we may see it included in a future update.

Model 3 Signal Stalk Retrofit

The move away from traditional stalks in favor of the steering wheel buttons on the Refreshed Model 3 has been a point of debate. While the author is squarely in the camp of steering wheel buttons (at least with the Cybertruck), many dissent and say that the buttons on the Refreshed 3 aren’t as satisfying or easy to use.

Many other drivers also prefer the tactile feel and muscle memory of a physical stalk for signaling. Tesla appears to favor stalks, as they retained the turn signal stalk with the new Model Y. There are also rumors that Tesla is going to reintroduce the turn signal stalk to the Model 3.

If Tesla adds stalks back to the new Model 3, current 2024+ Model 3 owners are still left without stalks. However, a user suggested adding stalks as a retrofit option. Lars said that he would try to consider a retrofitted signal stalk for the Refreshed Model 3, similar to the simplified version in the Refreshed Model Y.

While less definitive than the lumbar support response, it appears that Tesla may at least consider offering a stalk retrofit for the new Model 3. If you’re a lover of signal stalks and can’t wait for Tesla to get an official one - we recommend the Enhauto S3XY Stalks, which are customizable and feel very close to Tesla’s original fit and finish.

With that said, it’s nice to see Tesla incorporating more community feedback into its vehicle design these days. Perhaps one day, they’ll address the infamous auto wipers. They have gotten better, but they’re still not as reliable as what’s available in most other vehicles. With that said, we look forward to the changes that will emerge from these recent conversations.

Tesla to Issue TCU Fix That Prevents Vehicles From Sleeping in Update 2025.14.6

Sometimes, even with Tesla’s intensive bug-testing regime, bugs manage to make it out into the wild. In this particular case, a European user (@darkwaffle48484 on X) noticed that their 2024 Model 3 was using up more battery than normal while parked. Normally, they noted that the vehicle would lose about 1-2% per week; however, recently, they noticed much larger drops of 3-4% per night.

They monitored their Tesla widget and noticed the car wasn’t entering deep sleep. The widget consistently showed a recent connection time—usually within the past 45 minutes.

Fix Inbound

After discussing the issue with other Tesla owners and realizing it was somewhat widespread, they contacted Tesla Service. The service team confirmed that it was a firmware bug affecting the Telematics Control Unit (TCU), which prevented the vehicle from entering deep sleep mode.

The TCU is essentially the communications hub of your Tesla - and is mounted on the ceiling of newer vehicles such as the Model 3 and the new Model Y. It enables cellular and location services (via GPS) and also handles Wi-Fi and Bluetooth services. Tesla Service stated that this bug is planned to be fixed in update 2025.14.6, although the exact version number could change. However, they confirmed that they are aware of the issue and it is being addressed.

@darkwaffle48484

When the user reached out to Tesla Service, Tesla Service responded with the following (translated from Dutch):

“It has been confirmed that this is a firmware bug. The fix is in one of the next updates. Currently, it is planned for 2025.14.6 (subject to change). Do you have any more questions?”

Potentially Region-Specific

This bug could potentially be region-specific. TCUs often require specific hardware components, such as modems, as well as specific firmware versions that support different regions and cellular providers. These enable Tesla to comply with local cellular standards and regulations and ensure that your vehicle can connect to the networks available in that particular region.

At this point, it’s not clear when the fix will roll out, but given that update 2025.14.1 has practically stopped rolling out, Tesla may be waiting to resume the rollout with update 2025.14.3 or this 2025.14.6 version.

If you’ve noticed this issue and are in a non-European nation, let us know.
