A multi-millionaire is set to spend hundreds of thousands of dollars suing Tesla over a tiny tear in his seat.

Tech mogul Alain Cohen, 50, was one of Tesla’s first customers and forked out nearly $386,000 for three state-of-the-art cars — including $125,000 for a red Model S sedan.

But a few months after getting his newest vehicle in 2015 he says he noticed the back seat was squeaky and sounded like an “old taxi” — so he took it to a Tesla repair center.

Cohen claims mechanics trying to solve the problem managed to rip the leather interior and promised to replace the seat.

But after 12 months — and he claims dozens of ignored emails and blanked phone calls — Cohen insists the company has still not fixed the problem.

He might spend hundreds of thousands waging war against the electric car manufacturer just to highlight their “atrocious” customer service.

Tesla denies this is the case, and a spokeswoman said the company has been trying to install a new seat for months.

They also allege that Cohen — whose car is under warranty — demanded a new vehicle, plus an additional cash payment — something he denies.Cohen, CEO of internet

Cohen, CEO of internet start-up Bublup and biotech company Cobro Ventures, is now taking Tesla’s billionaire owner Elon Musk to court and suing for $50,000 damages.

The entrepreneur was a co-founder of software business OPNET technologies, which sold for $1 billion in 2012.

The businessman from Washington DC said: “I feel like I have had a love affair with Tesla and I’m a jilted lover now.”

“I love the concept behind the company but their customer service is atrocious. I have never seen anything like it.”

“How can you damage a car, promise to repair it and then completely go silent and never address the problem? You can’t treat customers that way.”

“I can’t recognize the company I used to love that was trying to do the right thing. They have become the most brutal company I have ever come across.”

“I was such a loyal customer and I feel bullied. I thought, ‘Wait a second, you can’t do that to me. Something has got to be done.’ The only recourse is to sue.”

“Nobody else has the resources to do it so I feel like I’m standing up for all their customers.”

“This will cost me many tens of thousands, maybe hundreds. I won’t win financially but this is a matter of principle. I will fight it all the way.”

Cohen owns two other Teslas and says he loves the company’s ethos and innovation — so much so that he also convinced his brother to also buy two.

But he says his opinion of the company has nosedived after he took his newest car to the Tesla repair center in Arlington County, Virginia, in August 2016.

He said: “It started with a little problem with the car. They took the seat out to see why it was squeaking and they said afterward that unfortunately, it tore.”

“It wasn’t particularly bad but they told me they were sorry and that it couldn’t be reupholstered so they would replace the whole seat.”

“I thought they were well intentioned. But then months went by.”

“They said they were still waiting for the seat and then they refused to even give an ETA.”

“I called and must have sent 20 emails. There was a very strong pattern of them ignoring me.”

“It has been a year since they did the damage and they still haven’t done anything about it, despite their own promise to solve the problem.”

“It’s ironic to me that they only way to get them to answer the phone is to sue them.”

“My hope is that people higher up will have to take notice and realize that they have lost their way as a company.”

“I would not buy another Tesla until I can see somebody at a higher level in the company say, ‘We are sorry, this shouldn’t have happened.’”

Cohen is suing for $50,000 in actual damages because of financial loss due to the “exorbitantly unnecessary” amount of time he needed to devote to the issue and lost value.

Tesla said it would “strongly defend” against claims that are unjust and lack merit.

A spokeswoman said they have been “trying to install” a new seat for “many months, but the customer has chosen not to bring in the car to have it replaced.”

She added: “Even though there are no remaining issues with his car, the customer has demanded a new vehicle, plus an additional cash payment.”

“These demands are simply unreasonable.”
