2005 Chrysler 300 c has a documented history of stalling since taking ownership of vehicle. Vehicle has stalled multiple times while driving. Dealership has attempted to reprogram the powertrain control module, clean the combustion chambers, and replace the manifold absolute pressure sensor; problem still exists. After the most recent occurrence of stalling I was unable to restart the vehicle. I took a video of the attempts to restart the vehicle as the dealership has never been able to duplicate the issue. I have also contacted Chrysler customer relations and they have stated that there is nothing they can do since the dealership cannot duplicate the issue even though I have shown the dealership the video of the stall / non-start issue. Vehicle has approximately 29,000 miles.
