I was driving in a construction zone near my home in heavy traffic in rush hour on august 21, 2019, when the vehicle stopped dead with no warning; the engine simply cut off. it would not restart. the car behind managed to stop, but the situation led to cars passing me by driving into the opposite lane in the face of incoming traffic. earlier i had been driving on a local highway at 65 miles an hour in heavy traffic, and the results could well have been significant injury. i had the car towed to a local dealer, where it was determined that the fuel pump had failed at a little over 23,000 miles. one mechanic there said that this type of fuel pump in this car was known to fail in the american southwest due to regional high temperatures; i have no way to verify that. i can upload the repair paperwork if that is helpful.
