Tesla Model X charge port fault: stranded at a Supercharger, charging again the same day
A Model X owner was stuck at the Heathrow Supercharger when the charge port stopped working. We found water damage from a blocked chassis drain, saved the original charge port, and had the car charging again within hours.

On a Friday afternoon, we had a phone call from a Tesla Model X owner who was stranded at the Heathrow Supercharger. The charge port had stopped working properly, and the car would not charge.
Fortunately, he had enough range left to reach our workshop, and we could start diagnosing the fault straight away.
The fault: a charge port door that did not know where it was
The motorised charge port door was no longer reporting its position correctly. The car could not tell whether the charge port was open or closed, and for safety it will not allow charging when it cannot be sure.
As always, we tried a calibration first, but the fault remained. Luckily, we had a new charge port door assembly in stock, so we could start the repair immediately instead of waiting for parts.
The root cause: water from a blocked drain
During disassembly, we found the root cause. The connector between the charge port door and the charge port itself had suffered from water ingress.
Looking further, we found why: a blocked chassis drain beneath the charge port area was letting water collect around the connector.
Saving the expensive part
We were able to clean and restore the connector, which saved the original charge port. We also cleared the blocked drain, so water cannot collect there again.
In the end, only the charge port door assembly needed replacing. That avoided a significantly more expensive repair.
Back on the road the same day
A few hours after that first phone call, the car was repaired, tested and charging normally again. The owner was genuinely surprised by the turnaround, and had not expected to be back on the road the same day.
Water and electrics do not mix
Water ingress is behind a surprising number of the faults we see, from a Model X ‘ninja door’ to a Model Y camera fault. Finding where the water comes from, and stopping it, is what makes the repair last.
If your Tesla will not charge, or is showing a charge port warning, send us a message or call us. If the car can still be driven, we can often look at it the same day.
