NHTSA Complaint #11197057 — 2018 MITSUBISHI OUTLANDER PHEV

STARTED VEHICLE AND IMMEDIATELY GOT MULTIPLE WARNINGS INCLUDING THE SERVICE ENGINE SOON LIGHT. WHEN I TRIED TO DRIVE THE CAR, IT HAD ALMOST NO ACCELERATION. IT WOULD NOT START THE GAS ENGINE AND THE REGENERATIVE BRAKING WAS DISABLED. THE RBS AND ACC WARNINGS WERE DUE TO THE SYSTEMS BEING DISABLED BECAUSE THE HYBRID SYSTEM WAS NON FUNCTIONAL. IT WAS ALL ON ELECTRIC BUT AT A SEVERELY REDUCED POWER LEVEL. I TRIED TO TURN OFF AND TURN ON THE CAR A FEW TIMES BUT THERE WAS NO CHANGE. I DECIDED TO TRY TO PLUG THE CAR INTO THE CHARGER FOR A MINUTE TO SEE IF THAT WOULD RESET IT, AND IT SEEMED TO HELP. THE CAR OPERATED NORMALLY BUT THE SERVICE ENGINE SOON LIGHT STAYED ON. I PULLED CODES AND GOT P0AA9 WHICH POINTS TO A FAILURE OF THE BATTERY VOLTAGE ISOLATION SENSOR INSIDE THE BATTERY CONTROL MODULE. I CALLED THE DEALER AND THEY TOLD ME NOT TO DRIVE THE CAR AND THEY TOWED IT TO THE DEALERSHIP (150 MILES AWAY.) THEY HAD TO REFLASH THE COMPUTER ANYHOW DUE TO 2 RECALLS AND THEY SAID THAT WAS WHAT TRIGGERED THE FAULT. THEY NEVER DID FIND A CAUSE BUT I DID NOTICE SOMEONE ELSE POSTED HERE THAT THEY WERE TOLD "THAT USUALLY DOESN'T HAPPEN THAT EARLY." MY CAR IS 8 MONTHS OLD WITH 3500 MILES ON IT.
