Engine Rattling And Whining Sounds problems of the 2010 Dodge Caliber

While driving on a major state highway, my temperature light came on and I heard a whining sound coming from the engine and my vehicle started to jerk. I was able to pull over to the shoulder when it stalled out. I let it sit for a couple of seconds and started the car. I took the car to the shop and they conducted a diagnostic check on the vehicle. I was told they found nothing wrong with the vehicle. They also told me that it could have been a lose gas cap that caused this issue. The last time I went to the gas station was about two days prior to the incident. I drove several places before the incident. If it was a gas cap issue, the car would have stalled out before that. Something needs to be done.
