2010 Jeep Patriot drivetrain & axles problems

My sister was driving my vehicle. She felt car wheels pulling to one side. Vehicle began to veer out of control where she tried to stablize. Picture taken after accident shows that bottom frame of vehicle became unattached from vehicle. The vehicle did not hit another vehicle or anything else solid. The vehicle was in motion on two way street where the vehicle was keeping straight with no turns.

While driving on I-75 in june 2014 the jeeps temp. Light went on regarding the transmission was overheating and started to slow down. I pulled off the and was lucky to find a jeep dealer. I explained what happened,and the dealer checked the trans fluid and said it was fine he also said it was the heat from the highway and the outside temp was 90 degrees. We continued and the car ran fine after that. The same thing happened on sunday sept 21 2014 driving through pa.
