The purchase of a vehicle is often one of the more expensive purchases a person makes in a lifetime. Motor vehicles contains many moving parts and advanced technology, which, if faulty, can render the motor vehicle inoperable or unsafe to drive. Unfortunately, in many cases, it is only after driving the vehicle for an extended period of time that the purchaser realizes the problem. Some auto dealers know of the problems that cars have but sell them anyway, without disclosing the issues. This can be fraud, and the victim may seek compensation.
