The most probably cause is mechanical wear-and-tear of components. When the machine is doing its work it is exerting forces on the materials that it is working on. By Newton's third law of motion, the material exerts an equal and opposite force on the machine parts. Now, the bit that is being worked on moves on and is replaced by the next bit to be worked on and then the next and so on. But it is usually the same part of the machine that is getting all the reaction. Over time that part wears down and so you get a loss of efficiency.

A reasonable belief that a crime has been committed. Example: You pull over a vehicle and while speaking with the driver smell the odor of marijuana in the vehicle.Added: Or observe a firearm, or what appears to be proceeds of crime inside the vehicle.ALSO: Be advised that these examples are only a small sample of reasonable causes to suspect criminal activity.
