A Tesla Model 3 on display at this week’s Shanghai Motor Show was used literally as a platform for a disgruntled owner.

An angry Tesla owner standing on the roof of a Model 3 display car at the Shanghai Motor Show deflected open umbrellas used by security guards attempting to cover her t-shirt slogan which said “brakes lost control”.

Tesla representatives initially asked the woman to step down off the roof of the vehicle but security guards stepped in when she refused their request.

However, the woman was able to deflect a number of open umbrellas held up by security guards in their lame attempt to cover her t-shirt slogan which claimed the brakes on her Tesla did not work.

The botched attempts to conceal the message merely attracted more attention to the scene, as onlookers began filming the incident on their phones, with some uploading the footage to social media.

The customer claims the brakes on her Tesla Model 3 failed, and four of her family members were almost killed in an accident earlier this year.

However, after checking the car’s onboard diagnostics (the equivalent of a 'black box' recorder), Tesla claimed data revealed the vehicle was traveling close to 120kmh and the car’s “braking and emergency warning systems had functioned properly”, the Bloomberg media agency reported.

Tesla told the news outlet the customer “is widely known for having repeatedly protested against Tesla’s brake issue.”

In a statement published by Bloomberg, Tesla said it “places great emphasis” on consumer rights, and has been negotiating with the customer but has reportedly so far failed to reach a resolution.
