20200228ELECTRICAL SYSTEM
ON THURSDAY, FEBRUARY 27, 2020 MY VEHICLE WAS NOT STARTING IN ORDER TO TAKE ME HOME AT 9:40 PM. DUE TO THE FAILURE OF THE ESL IN THE STEERING COLUMN I AM NOW FORCED TO WAIT HERE UNTIL A TOW TRUCK COMES. I DO NOT FEEL SAFE IN THIS LOCATION AND WISH MY VEHICLE WOULD START KNOWING THAT IT HAS THE CORRECT AMOUNT OF VOLTAGE AT THE BATTERY.

THE ESL STEERING LOCK MALFUNCTIONED. THIS CAUSES THE CAR NOT TO START. I HAD THE AIRBAGS REPLACED DUE TO RECALL ABOUT 3 WEEK SALES EARLIER. THE CAR WAS WORKING PROPERLY THE DAY BEFORE AND THE NEXT MORNING THE CAR WON'T START AND A MESSAGE COMES UP ABOUT REMOVING THE KEY.
