2014 TOYOTA SCION Electrical System Problems

I HAVE A 2014, SCION XD, I WAS DRIVING HOME IN THE RAIN GOING ABOUT 60-65 ON THE INTERSTATE. WHEN MY CAR LOST POWER. MY RADIO WENT OUT, A/C OFF. LIGHTS OFF, WIPERS STOPPED RIGHT IN FRONT OF MY FACE BLOCKING MY VIEW AND MY STEERING WHEEL LOCKED. ALL MY DASHBOARD LIGHTS CAME ON. NOT SURE HOW LONG POWER WAS OUT BUT IT DID COME BACK ON. LUCKILY THIS TIME IT DID NOT CAUSE AN ACCIDENT I WAS ABLE TO GET OFF THE INTERSTATE SAFELY WHEN THE POWER CAME BACK. I LET THE CAR SIT AND RESTARTED. THE CHECK ENGINE LIGHT, AIRBAG LIGHT AND TRAC OFF WERE STILL ON. BIG SAFETY CONCERN. HAD TO HAVE THE CAR TOWED TO THE DEALERSHIP WHERE THEY TOLD ME THE COMPUTER DID NOT PICK UP ANYTHING. IT WAS JUST A GLITCH MEANING A PROBLEM THEY COULD NOT FIGURE OUT. WHAT DO WE DO ABOUT...

I PURCHASED MY CAR BACK IN OCTOBER BRAND NEW NO MILES. WHEN I WAS LEAVING THE DEALER SHIP I NOTICED MOISTURE IN THE TAIL LIGHTS. I CALLED THE DEALER SHIP THEY SAID THEY HAD TO SEE IT HAPPENING. IT DID NOT HAPPEN AGAIN TILL ABOUT JANUARY. I TOOK MY CAR IN AND TO HAVE THEM SEE THE TAIL LIGHTS AND THEY SAID IT WAS A ISSUE AND REPLACED THE DRIVERS SIDE TAIL LIGHT DUE TO IT BEING THE ONLY ONE HAVING THIS ISSUE AT THE TIME OF MY VISIT. A WEEK AFTER THEY REPLACED THE TAIL LIGHT IT HAPPENED AGAIN. THE DEALER SHIP EXPRESSED THE CONCERN FOR SAFETY FOR THIS ISSUE AND REPLACED THEM AGAIN. WHILE IN THERE FOR THIS VISIT THE OWNER OF THE DEALER SHIP CAME UP TO ME AND SAID ITS A KNOWN ISSUE WITH THE CAR AND THAT THEY WOULD TRY THEIR BEST TO FIX THIS...
