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.

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.

Tesla Stock Plunges Amid Musk and Trump Feud: A Timeline of Today's Events

By Not a Tesla App Staff

Elon Musk’s relationship with Donald Trump has quickly shifted from cooperation to conflict, as the two exchanged comments earlier today.

Musk’s companies operate in sectors that are either heavily regulated—or, in his view, not regulated enough. His political involvement makes more sense when seen through the lens of shaping policy: he’s pushed for looser regulations around SpaceX, more consistent standards for autonomous vehicles, and more oversight of artificial intelligence.

But after today’s back and forth, Trump is now threatening to eliminate all EV subsidies and cancel SpaceX contracts.

While we don’t usually cover politics, Musk’s recent criticism of Trump’s new spending bill could and likely will negatively affect both Tesla and SpaceX.

The fallout is already impacting Tesla stock, which fell 14.26% today and has dropped another 2% in after hours trading.

Below is a thread outlining the public exchange between Musk and Trump.

On June 3rd, Musk posted a comment to X criticizing Trump’s new bill due to it drastically increasing the nation’s debt.

Today Trump responded on Truth Social saying the bill is necessary to prevent tax increases.

Trump says in an interview that Musk knew the inner workings of the bill, but is only now speaking out about it. while Musk denies being shown the bill at all.

Trump turns on Musk, and goes back to his anti-EV campaign.

Trump is now threatening to end government contracts for SpaceX, which Musk is calling his bluff on, saying that SpaceX can start decommissioning the Dragon spacecraft immediately.

While we thought this would be the end of political involvement for Musk, he still appears to want to have a larger voice in politics.

It’ll be interesting to see how the Tesla stock reacts tomorrow. We may be in for another rough ride as Trump looks for additional ways to make Musk’s life more difficult. As we saw in the NJ Turnpike case, where Tesla is being forced to decommission all of their Superchargers along the popular route, the best product doesn’t always win.

Tesla Supercharger Network Sees Strong Growth in Q1 2025 With 2,200 New Stalls

Tesla Supercharger network continues to expand, despite issues with the NJ Turnpike that will force several Supercharger sites to shut down, and even Tesla laying off a huge portion of the Supercharger team in 2024.

Tesla recently shared statistics on its Supercharger expansion in the first quarter of 2025. The numbers highlight the work that Tesla’s teams are doing to expand the network and keep up with the growing demand from Tesla and non-Tesla vehicles.

Q1 2025 By the Numbers

Here’s how the Tesla Supercharger network performed in the first quarter of 2025.

Tesla brought online approximately 2,200 new Supercharger stalls worldwide, representing a 17% year-over-year growth for the quarter. That’s impressive growth, especially since Tesla is simultaneously working to transition older V2 stalls to V4 stalls.

Overall, Tesla delivered 1.4 TWh (that’s terawatt-hours) of energy to vehicles, representing a 26% year-over-year growth. More people than ever are using the Supercharger network - and with 42 million charging sessions in Q1 2025 (27% annual growth), Tesla is the de-facto standard for EV charging — even if the NJ Turnpike authorities don’t want to believe it.

That 1.4 TWh accounts for approximately 173 million gallons (657 liters) of gasoline being saved, which offsets 1.5B kilograms of CO2. While that may pale in comparison to the billions of metric tons of CO2 emitted by passenger vehicles every year in the US, it is still a significant amount of carbon being offset.

More Changes Coming

With such a strong start to the year, we can expect Tesla to continue posting impressive numbers throughout Q2 and likely throughout the remainder of 2025. Tesla’s pace of opening over 2,000 stalls (equivalent to 250 8-stall sites) per quarter seems to be well established, which means more density, faster charging, and more range for more parts of the world.

Looking into upcoming Supercharger improvements, Tesla intends to launch 500kW Supercharging for the Cybertruck by Q3 2025, alongside the first deployments of the V4 Supercharger cabinets. Tesla has also recently announced an upcoming change to Supercharger pricing and that Virtual Queues are coming, which won’t force you to wait in line at congested Superchargers.
