On 10/15/19 i was returning my vehicle to lustine chrysler jeep dodge in woodbridge, va for engine knocking and transmission thumping when (i'm pretty sure i hit a bump on the highway) and the whole electronic dashboard flicker very fast and the vehicle accelerated on its own. i arrived at the dealership, they verified a malfunction code and sent me home to return another day because they didn't have any loaner vehicle to give me. i have loud engine knocking, thumping transmission and the ac blower didn't work october 1, 2019.
