Lexus of Pembroke Pines

My daughter bought a mini cooper roadster 2013 with 14700 miles, in 10/16/2017, from Lexus of Pembroke Pines. After one month she noticed an engine oil leaking and she left the car on the BMW of Coconut Creek to fix the problem, once the car was yet in warranty and the service on the engine would be done without costs. BMW found that the engine was not the original engine but was changed for an older engine and the warranty was terminated by this reason. We contacted Lexus about the problem and Lexus admitted the problem and the car was returned to Lexus and my daughter signed all documents about 20 days ago to cancel the finance and had her down payment of $ 10,000 returned to her. She needed the money to buy another car and she rented a car to go the her job while the money was not sent to her and she believed the money would be sent in a few days. After 20 days of waiting for the money , she called Lexus and they said they sent the check to the loan company , Bank of America and she had to call the Bank to have her money back. She called the Bank and they said the money will be put in hold for 16 days. Lexus exempted itself from the problem saying they could do nothing and the Bank said it has its rules and could not release her money before 16 days. My daughter will assume the cost of more than 36 days of a leasing car, not mentioning other problems she had. What a shame for this Lexus company that sold a car with such a fraudulent problem and did not assumed the payment of my daughter costs. Please don't buy any used car from this company. They are not trustworthy.
