A couple of months ago, the owner of a brand-new Tesla Model Y claimed the glass roof panel flew off as they were driving on the highway, turning the electric crossover into a convertible. To make matters worse, the incident happened just a few hours after they drove it off the dealer lot. And now it's happened again, this time to a Tesla Model S. Unlike the last video, we get to see the roof detach from the moving car.

Alarming footage recorded from another car's dashcam shows the roof flying off a passing Tesla Model S driving at high speed on a highway in China, narrowly missing the car that recorded the incident.

That must have been a shock for the driver, who applies the brakes as soon as the roof flies off. It looks dramatic as the glass roof panel flies high into the air, but luckily it didn't hit any other cars or cause an accident, so nobody was injured. It could have easily hit the camera car if it was driving behind the Model S in the same lane. So what happened here exactly?

It's no secret that Tesla models are often plagued with quality control issues, from exterior panel gaps to scratched interiors. In response to the Model Y's issue, Tesla acknowledged that a small number of models may have a problem with the roof. In this case, however, the roof was replaced by a third-party shop.

A few hours after the video was uploaded to Weibo, Tesla China spokesperson responded with the following translated statement: "We have contacted the owner of the car as soon as possible and are helping the owner solve the problem as soon as possible. After preliminary investigations, the vehicle had undergone roof glass replacement at a third-party authorized repair center. We are currently investigating the cause of the incident."

While the shop that replaced the glass roof is being blamed, Tesla could still be held responsible since the work was done by an authorized third-party body shop. Tesla's investigation should reveal if the roof was replaced correctly, but at least this doesn't appear to be a widespread issue with the Model S so we hopefully won't see any more videos of roofs flying off the electric sedan.
