Tesla Motors Corp. (TSLA) is in trouble once again.

The electric car maker is being sued by a South Korean actor and singer for sudden acceleration of its Model X car. According to a Reuters report, Ji Chang Son’s filing claims that the car’s “spontaneous acceleration” in September destroyed property in his home. “The vehicle spontaneously began to accelerate at full power, jerking forward and crashing through the interior wall of the garage, destroying several wooden support beams in the wall and a steel sewer pipe, among other things, and coming to rest in Plaintiffs’ living room,” the filing stated.

Son is suing the Palo Alto-based company for product liability, negligence, and breaches of warranty. He has also asked the court to convert his case into a class-action suit based on seven previous claims on the same issue by Tesla owners. Those cases have been documented by the National Highway Transportation Safety Commission.  

But Tesla is not taking the bait. (See also: What Makes Tesla's Business Model Different?)

Based on its own investigation into the accident, the company claims that Son pressed the accelerator pedal “all the way to 100 percent.” In a statement to online publication Electrek, Tesla also charged Son with threatening “to use his celebrity status in Korea to hurt Tesla unless we agreed to make a financial payment and acknowledge that the vehicle accelerated on its own. However, the evidence clearly shows the vehicle was not at fault.” 

The company has maintained a similar line of defense in previous instances of such claims. For example, in one such case, the electric car company said its cars “do not accelerate without the driver instructing it to do so.” An investigation into the claims by Electrek resulted in a “he said she said” situation, where both parties – the aggrieved Tesla owners and the company – stuck to their lines of argument and there was no independently verifiable source of data.
