After turning onto the main road out of our subdivision the vehicle shut down and would not start. The car behind us nearly ran into the back of the vehicle. It appears there is a design flaw in the tensioners used for the timing chains on the motor in this vehicle. The tensioners are a plastic that cannot hold up to the heat and eventually deteriorate prematurely. Apparently when one of them fails the vehicle automatically shuts off the engine causing the driver to lose control.
