Toyota Camry
The Toyota company is famous as a manufacturer that pays attention to the quality of its products. So, in 2012, when they made a deal with the U.S. government to pay $1.2 billion to avoid criminal prosecution, the car community realized that even Toyota was covering something up. The thing that Toyota desperately wanted to hide was unintended acceleration on various Toyota and Lexus models due to a faulty part (via Toyota).
In fact, for several years, the company was hiding documents showing that they knew about the problem but decided to do nothing about it. However, when they brought the case to light, Toyota paid all the expenses and settled it out of court. In fact, they recalled 9.3 million cars in one of the biggest recall cases in history.
