So I want to make sure I have this right.Our contract law is built on the foundation of a shared knowledge base between the two people entering into a contract. The law is very clear that withholding material information from someone to induce them to enter into a contract is fraud.
You entered into a contract with Tesla to buy a car as it was presented at the time of your purchase agreement. You received that car.
It is common knowledge that Tesla updates their products as those updates are ready. Good luck arguing in court that, under those conditions, Tesla committed fraud. Good luck even finding an attorney who would take that on!
