The leak is real
It starts in the back. Specifically the left rear corner of the panoramic roof. It just lets go.
Owners of the BYD Ti7 in China are complaining. Loudly. The glass detaches within a week of picking up the car. Water gets in. It leaks. Then it floods the charging port at the back. Not great.
There are three hundred complaints on the record. 12365autol, the platform for consumer grievances in China, is tracking them all. These aren’t just noise complaints. Or wind noise, though that’s bad too. This is structural. Or rather structural adhesion failure.
And it’s only the EV.
The Plug-in Hybrid versions? No reports yet. The issues started right after the all-electric Ti7 launched in late April. That timing matters.
Why does it come loose
You can push it down. Temporarily. But it pops right back up.
SMZDM noted this earlier. They saw charging ports turning into little indoor swimming pools. The water drips down the side. Straight into the charge port. One complaint from mid-June even showed photos. That post was deleted though. Probably for safety reasons. Or liability.
People think it’s a factory thing.
3YC Ownership Report suggests uneven glue or wrong force during installation.
It wasn’t the design. PHEV models are fine. If it was a design flaw everyone would be broken. This smells like production. Maybe the ramps. Maybe the hands shaking while applying adhesive.
The silence from BYD
They answered most of them. 99.2%. But answering isn’t fixing.
One guy says BYD called. Asked him to delete the bad review. Offered a “fix” in exchange for silence. He said no. Nothing happened after that. No money. No repairs. Just a void.
Thirty-one specific cases have been filed officially. BYD’s response is basically bureaucratic stalling. “Forwarded to authorities,” they say. “Wait for contact.”
People are waiting.
Sales still ticking
The car still moves. A lot, even.
Back in December, the Ti7 was the third best-selling SUV in the whole country. Thirty-four thousand units. Now it’s slowing. May delivered 17.5 thousand. Still a lot.
But look at the EVs specifically. May got 1.8 thousand. June? Nearly five thousand.
They cranked up EV production. That’s exactly when the roofs started falling off.
Maybe that’s coincidence. Maybe not. BYD is quiet. They’re supposed to comment soon.
Until then the rain keeps falling. Into the charge ports. 🌧️
