After pulling into a shopping area parking lot, with the car stationary and the engine off, the door locks failed to open trapping us in the car in the sunlight of a 90 degree day, pressing the key unlock actuator to unlock the doors by using the key unlock button fails to unlock the doors thereby preventing the occupants from getting out of the car. This has happened more than once and has subjected my wife and I to being trapped in the car in rapidly rising heat for more than a few minutes until after repeatedly pressing the key unlock button the doors unlock. The car is not capable of starting during this time. This frightening circumstance has now happened a few times - not comfortable for two people in their seventies.
Power door locks did not operate for car doors or trunk via the remote key fob. The key would not manually unlock the car doors. There is no manual key access for the trunk.
