Carlos Thomas, a Cybertruck owner from San Antonio, Texas, says his house nearly burned down when an issue occurred while he was charging his Cybertruck.
Carlos explains that last night at 9:12 PM, he received a notification on his phone stating there was a “communication error” with his truck, and his Cybertruck stopped charging at 41%.
Curious about what was going on, Carlos went to the garage where he had left his Cybertruck plugged in to charge.
To his shock, he found the entire garage filled with smoke.
Thankfully, Carlos says the breaker eventually tripped, stopping the electrical issue before it could burn down his house.
This is definitely not ideal, and Carlos points out that the issue is especially odd because he has two Tesla chargers installed in his garage, and the one charging the Cybertruck is the one with the electrical problems.
Even more surprising, Carlos states that his house is new, having been built last November, and he moved in with his family this April.
A modern house, almost burning down while charging an electric vehicle, is certainly concerning, and the Cybertruck owner shared his story on the Cybertruck Owners Club forum.
He writes…
“Last night at 9:12 pm, I got a ‘communication error’ while charging my Cybertruck. It stopped charging at 41%.
I went out to the garage to check, and the entire garage was filled with smoke. Thankfully, the breaker tripped, and the Cybertruck appears to be okay.
The house was built in November 2024, and I moved in April 2025. We have two Tesla Wall Connectors.
The builder sent us the company that did the electrical work, and they are here now.
Thoughts?”
Below his post, Carlos shared several videos and pictures. The first two videos show his Cybertruck parked in the garage.
The Cybertruck is connected to one of the Tesla chargers, which displays a pulsing downward light indicating proper charging.
However, a few seconds into the video, sparks begin flying from the Tesla wall charger connected to the Cybertruck.
The sparks continue for a few seconds until the charger stops outputting power.
In addition, Carlos shared multiple pictures showing the aftermath of the incident.
As you can see, the wiring behind the Tesla charger is completely fried. After opening the back panel, Carlos shows the burnt electrical cables.

This is definitely not ideal, and looking at the comments, fellow Cybertruck owners suggested that the issue stems from the house’s electrical system, not the Cybertruck or the Tesla charger.
A fellow Cybertruck owner from Florida, Ken, writes…
“I’m not an electrician, but I’d be cautious looking at those wires. Someone clearly made a mistake during the installation, and that person should not be an electrician.
That’s one of the reasons I installed a smoke alarm in my garage.
I’m glad you had a camera, because it shows exactly what happened instead of just guessing. Great idea to have the camera in the garage.
Every time I think about canceling my homeowners insurance except for liability, I see a video like this, and it reminds me that fires can happen anywhere.”
Another Cybertruck owner, Dev from Nebraska, says…
“I am not an electrician, but I’ve done enough DIY to agree the issue is improper installation. And to me, the wires going out to the charger look to be the wrong gauge—they look quite thin.”
A third Cybertruck owner, Ace from Arizona, adds…
“As previously stated, glad you and your family are safe.
Sometimes I feel such rage when someone puts my family in danger despite all my efforts to protect them. I wouldn’t trust myself around that electrician, to be honest.”
Most Cybertruck owners pointed the finger at the electrical work. After a bit of time and an electrician’s visit, Carlos confirms that the problem indeed lies with the type of wiring used to power his Tesla charger.
Carlos writes…
“As an update: my problem seems to be that I have a ROMEX 6/2 electrical cable running from my panel, through my walls, to my Tesla Wall Charger.
ROMEX 6/2 is only rated for 55 amps. Operating a continuous load at 48 amps to charge my Cybertruck exceeds that capacity.”
ROMEX 6/2 cable is typically used for powering energy-intensive household items, such as air conditioning units and ovens. Still, it’s at its limit for EV charging, especially for the Cybertruck, which draws 48 amps constantly.
For Cybertruck chargers, it’s recommended to use high-capacity cables, such as THHN/THWN-2, rated for 65–75 amps and capable of withstanding temperatures up to 90°C.
Cybertruck owners should verify that they are using appropriate high-capacity electrical cables for their chargers.
