2013 ACURA ILX Steering Problems

Issue had not been persistent, on Sunday, May the 12th, 2024, while driving home, I was on a slight downward slope coming to a halt at a red light, when the car jolted slightly and the warning lights came. The auto-shutoff feature on the vehicle stopped working immediately. I was able to drive the car home, but after parking - the vehicle wouldn’t start again. Electronic screen on the radio came on and I could see error codes P1437 & P15A5. Also warnings on the dash to check IMA system, check charging system, check battery, check breaking system.

DTC'S P0A78 - MPI INTERNAL CIRCUIT MALFUNCTION, P1440 - MPI OUT CIRCUIT MALFUNCTION. MPI FAILING INTERNALLY, CAUSING 12V BATTERY TO LOSE CHARGE. Previously parts involved were recalled in Dec...
