2015 Toyota Prius Electrical System

When I parked my car and stopped the engine after driving for 90 min/62 miles on June 22, 2023, I found that I couldn't lock my car's door, through my remote, door handle or the switch inside the door. Upon further examination, I saw complete loss of the power: no light, no audio, no other accessory power, no start of engine. Foot press on the brake feels heavy/less responsive. One hr after the incident I went back (because I had some business to attend) to the car, everything looked normal (with full functions recovered) as if nothing happened before. 6 hrs later the car still behaved fine. I measured 12-v battery and it registered 12.3 v (I bought the car new 8 years ago and I haven't changed the battery yet). I noticed that my the clock in the car lost 10 mins (behind correct time) and I concluded the complete loss of battery power lasted about 10 mins. By the time of this report, I have started the engine 5 times without any problem but this loss of power gravely concerns me. I saw recalls for similar problems affecting similar prius models/years however my car is not on the list.

Window buttons on drivers side master power window switch failed. Felt warm on door. There have been recalls of other models of Toyota cars including Prius C.

During routine low speed suburban driving, a fire started under the hood in the right front of the car. The smoke was first noticed by a pedestrian so I pulled over, got out of the car, and called 911. I had no prior warning of any sort. The fire completely destroyed the car. This is being investigated by Toyota. I have photos and would be happy to provide more details.

WHILE DRIVING, LEFT SIDE OF INSTRUMENT PANEL WENT DARK. NO SPEED INDICATION AND CRUISE CONTROL TRIPPED OFF. STARTED CAR NEXT DAY AND INSTRUMENT PANEL WAS NORMAL. WHILE SITTING IN DRIVEWAY WITH ENGINE RUNNING, ENGINE STOPPED AS NORMAL FOR THE HYBRID PRIUS, WHEN THE ENGINE TURNED OFF, THE LEFT SIDE OF THE INSTRUMENT PANEL AGAIN WENT DARK. DIMMER SWITCH AT FULL BRIGHT AND NOTHING BLOCKING MIRROR FOR COMBINATION PANEL (INSTRUMENT CLUSTER).

RANDOM ELECTRICAL PROBLEMS STARTED HAPPENING. BLUETOOTH WOULD NOT ALLOW ME TO ANSWER INCOMING PHONE. I COULD NOT CALL OUT. UNABLE TO CHANGE RADIO STATION, TURN ON/OFF RADIO.

WITHIN A 6 DAY PERIOD, THE MAIN 12 VOLT BATTERY DIED AND THE CAR WHICH WAS ONLY 3 WEEKS OLD WOULD NOT START. ALSO THE CABLE USED TO CHARGE THE HYBRID BATTERY TRIPS THE CIRCUIT BREAKER IN MY HOUSE EACH TIME EVEN THOUGH IT IS A GROUND FAULT OUTLET AND A 20 AMP BREAKER. I HAD TO CALL OUT A TOW TRUCK TO JUMPSTART THE BATTERY BOTH TIMES. CAR WAS PARKED AND DIRECTIONS WERE FOLLOWED EXACTLY FOR CHARGING IT. I TOOK IT TO THE DEALER WHO FOUND NOTHING WRONG AND WAS TOLD I SHOULD HAVE A DEDICATED LINE TO CHARGE THE CAR, EVEN THOUGH I WASN'T TOLD THIS BY THE SALESMAN. THE ELECTRIC SERVICE IN MY GARAGE IN BRAND NEW. THIS IS RIDICULOUS TO GO TO THIS EXPENSE AND NOT BE TOLD IN ADVANCE, AND TO HAVE A NEW BATTERY NEED CHARGING. IT HAD TO BE CHARGED BEFORE I COULD EVEN TEST DRIVE THE CAR BUT THAT DID NOT MATTER. I WAS TOLD I COULD NOT GET A NEW BATTERY AS IT TESTED "GOOD".

THE NAVIGATION AND AUDIO SCREENS ARE MOSTLY UNREADABLE IN BRIGHT SUNLIGHT. IN ORDER TO ATTEMPT TO SEE THE SCREENS IN THESE CONDITIONS SOME OPERATORS MAY BE DISTRACTED FROM THE ROADWAY IN ORDER TO READ THE SCREEN INFORMATION. THESE DISTRACTIONS MAY INCLUDE MOVING HEADS AWAY FROM THE WHEEL AREA IN ORDER TO GET A BETTER VIEW OF THE SCREEN OR ATTEMPTING TO HOLD OBJECTS ABOVE THE SCREEN IN ORDER TO MINIMIZE THE GLARE FROM THE SUNLIGHT. COMPLAINANT HAS OWNED PREVIOUS MODELS OF TOYOTA PRIUS WHICH DID NOT HAVE THIS PROBLEM.
