Owner report 11172193 · 2019-01-25 (January 25, 2019)
WHEN PARKED IN NEUTRAL WITH THE CLUTCH PEDAL NOT DEPRESSED WHILE RUNNING MY CARS TRANSMISSION MAKES A WHINING NOISE AND ONLY GOES AWAY WHEN YOU DEPRESS THE CLUTCH PEDAL TO ENGAGE THE CLUTCH. ONCE YOU RELEASE THE CLUTCH IT CONTINUES MAKING THE NOISE. HOT AND COLD TEMPERATURES DOESN'T MAKE A DIFFERENCE. THE DEALERSHIP THINKS IT'S THE BEARING IN THE TRANSMISSION BUT NOT 100% SURE UNTIL I PAY THEM TO OPEN TRANSMISSION. TOYOTA HAS A HISTORY OF BEARINGS GOING BAD IN THE TC TRANSMISSIONS AND WILL NOT DO ANYTHING AND REQUESTS YOU TO BUY A NEW TRANSMISS…

Owner report 11326881 · 2020-06-01 (June 1, 2020)
MY 2015 SCION TC AUTOMATIC HAS ROUGH SHIFT POINTS, ROUGH IDLE AT STOP SIGNS. THE SCION FRS HAS THE SAME ISSUES AND TOYOTA ISSUES A TSB FOR SHIFT ENHANCEMENT THAT FIXED THEIR TRANSMISSION ROUGH SHIFTS AND ROUGH IDLE. I'M HOPING THAT SCION OR TOYOTA ARE LISTENING AND WE NEED THIS FIX TOO! RESETTING THE COMPUTERS BY DISCONNECTING THE BATTERY FIXES THE ISSUE TEMPORARILY, SINCE THIS IS A 'LEARNING' TRANSMISSION, IT ALWAYS SEEMS TO DEFAULT AND STARTS TO SHIFT ROUGH, SHIFT TOO OFTEN OR BACK TO BACK EVEN IN CITY DRIVING. IT'S GEAR HUNTING AND I'M SO SI…

Owner report 10704279 · 2015-04-07 (April 7, 2015)
2015 SCION TC 6 SPEED MANUAL. THE EMERGENCY BRAKE WILL LOCK UP AFTER SITTING IN THE DRIVEWAY FOR SEVERAL PLUS DAYS AND I HAVE TO APPLY A LOT OF GAS FOR THE BRAKES TO RELEASE SO I CAN DRIVE THE CAR. AT THE TIME OF THE EMERGENCY BRAKE RELEASE THERE WAS SUCH A HUGE BANG THE FIRST TIME IT HAPPENED I THOUGHT I RAN SOMETHING OVER. MY SAFETY CONCERN IS THE FAILURE OF THE BRAKE SYSTEM FROM THE FORCED RELEASE OF THE EMERGENCY BRAKE. IT HAPPENS MORE OFTEN WHEN THE WEATHER IS HOT AND NOT SO MUCH OVER THE WINTER MONTHS. I HAVE MADE A COMPLAINT TO TOYOTA …

Owner report 11460618 · 2022-04-13 (April 13, 2022)
Over the past 4-5 years, 2015 scion tc has had numerous electrical issues. Both driver and passenger electric door locks do not work. Head and tail lamp lights burn out frequently. Seems like a grounding issue? Car failed to start August 2021 due to electrical problems. 3rd party mechanic fixed the issue. Toyota Dealer-installed automatic start fails multiple times before starting car. Basic electrical mechanisms for a car made in 2015 should not be broken/failing. 2019 Air Conditioner wouldn't drain. Had to investigate and personall…

TRANSMISSION DOES A HARSH/JERK DOWNSHIFT WHEN COMING TO A STOP. IT DOES IT RANDOMLY, USUALLY WHEN COMING TO A STOP SLOWLY. IT'S NOT SAFE, FEELS LIKE THE CAR LURCHES INTO 1ST. TOYOTA RESET THE COMPUTER AND IT WAS OK FOR A BIT BUT CAME BACK. I'M THINKING IT'S THE SOFTWARE OF THE CAR. TOYOTA SAID IT'S A LEARNING TRANSMISSION, BUT SOMETHINGS WRONG. IT'S SCARY TO DRIVE IN TRAFFIC, AND ONLY HAVE 33K MILES. THE TRANSMISSION FLUID WAS CHANGE BY TOYOTA LAST YEAR WITH THE WS AND IT HAS NOT FIXED THIS ISSUE. I'M WORRIED THE CAR MAY STALL IN STOP AND GO OR…
