2015 SCION TC Complaints

The contact owns a 2015 Scion TC. The contact stated that the air bag warning light remained continuously illuminated while operating the vehicle. The contact stated that when the air bag warning light was illuminated, the horn was inoperable. The vehicle was not diagnosed or repaired. However, an independent mechanic informed the contact that the failure might be associated with an inoperable clockspring. The manufacturer was not notified of the failure. The approximate failure mileage was 130,000.

Whining noise is heard when the clutch petal is released. Noise is coming from the input shaft bearing. Common failure on this model. Mechanic confirmed that is the issue. If the bearing completely fails could leave the car stranded and cause more damage to other transmission components. No warning lights but noise is very loud.

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 personally drain the tubes behind the passenger and driver side-pannels behind center counsel. The entire draining system for the cars air conditioner had clogged. 2015 Exterior Vinyl Pillars on sides of windshield started to fade. Brought it to Westbury Toyota and they said the sun caused it. I didn't even have the car for 6 months yet....

Rear suspension components were loose on vehicle. My car was purchased with rear trd coilovers installed at factory. Suspension components were improperly tightened according to Toyota dealership who serviced my vehicle. Purchased car stock and never had suspension work done in the past. This is similar to NHTSA campaign 15v228000 recall on same car year/manufacturer/model/edition (2015 Scion tC release series 9.0) but my VIN was not part of the 114 out of the 2000 cars sold.

TL* THE CONTACT OWNS A 2015 SCION TC. THE CONTACT STATED THAT WHILE PARKED AND SEATED IN THE VEHICLE, THE CONTACT HEARD AN ABNORMAL SOUND LIKE A SHATTERED GLASS. THE CONTACT EXITED THE VEHICLE AND BECAME AWARE THAT THE CENTER SUN ROOF GLASS HAD SHATTERED. THE CONTACT STATED THAT THE SUN ROOF HAD SHATTERED WITHOUT IMPACT OR INCIDENCE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 85,000.

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 LURCH SO HARD FIRM THE 2-1 DOWNSHIFT THAT I MIGHT HIT THE CAR IN FRONT OF ME AND CAUSE AN ACCIDENT.

TRANSMISSION JERKS WHEN SLOWING DOWN TO A STOP, 50/50, IT SEEMS TO BE DOING A HARD DOWNSHIFT 2-1 BEFORE THE STOP. IT'S SCARY AND FEELS LIKE YOU GOT REAR ENDED. THERE IS ALSO A CLICK NOISE WHEN THE DOWNSHIFT HAPPENS. TOOK IT TO TOYOTA AND HAD A TRANSMISSION DRAIN AND FILL, WHICH THEY SAID THE FLUID WAS AS CLEAN AND THE COMPUTER HAS NO STORE CODES. THE RESET THE TRANSMISSION CONTROL MODULE AND THE ISSUE HAS RETURNED, IT SHOULDN'T HAVE THESE ISSUES AT 19K MILES! ALSO THE TRANSMISSION HESITATES GOING INTO TRAFFIC, WHICH CAN CAUSE AN ACCIDENT BECAUSE IT SEEMS LIKE IT DOESN'T KNOW WHAT GEAR TO BE IN. I WISH TOYOTA WOULD READ THE OTHER PEOPLE'S COMMENTS WHO HAD THE SAME ISSUES WITH THIS U760E TRANSMISSION. THIS IS A SAFETY ISSUE AND NEEDS TO BE CORRECTED. I'M WORRIED FOR THE LONGEVITY AND I FEEL I WASTED MONEY TRYING TO DO A TRANSMISSION SERVICE WHICH WAS SUGGESTED BY TOYOTA AND THAT DIDN'T FIX A THING.

I WAS DRIVING ON THE FREEWAY ON MONDAY DEC 28 HEADING TO WORK IT WAS RAINING HARD AND WAS DRIVING AT THE SAME SPEED AS EVERYONE ELSE IN THE FREEWAY OUT OF NOWHERE MY STEERING TOOK OVER CONTROL AND I SPINNED AROUND HITTING THE CARPOOL LANE DIVIDER AND WAS TOSSED TO THE 4TH LANE AFTERWARDS. AT THAT MOMENT I WAS IN FRONT OF A SEMI TRUCK AND COULDN'T BRAKE IN TIME AND HIT ME SENDING ME BACK TO THE CARPOOL LANE ANY TIME OF THOSE HITS MY AIR BAGS NEVER TURNED ON.

TL* THE CONTACT OWNS A 2015 SCION TC. THE CONTACT STATED THAT WHILE APPROACHING AN INTERSECTION, THE ACCELERATOR PEDAL WAS DEPRESSED HOWEVER, THERE WAS A DELAY IN VEHICLE RESPONSE. THE CONTACT ALSO STATED THAT THE VEHICLE DOWNSHIFTED INTERMITTENTLY WITHOUT WARNING. THE VEHICLE WAS TAKEN TO TOYOTA OF SANTA MARIA (700 E BETTERAVIA RD, SANTA MARIA, CA 93454) TO BE DIAGNOSED, HOWEVER, THE MECHANIC WAS UNABLE TO RETRIEVE A FAULT CODE OR DUPLICATE THE FAILURE. THE MANUFACTURER WAS CONTACTED AND MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 18,000. *BF*JB

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 SICK OF IT. TOYOTA SAID THEY CAN'T FIND ANYTHING WRONG, I DID A TRANSMISSION DRAIN AND FILL WITH TOYOTA THINKING IT WOULD FIX THE ISSUE AND IT NEVER DID. IT'S THE ECU OR TCM, WE NEED THE UPDATE JUST LIKE YOU GUYS DID FOR THE FRS AND YOU FIXED THOSE ISSUES! SO PLEASE FIX OURS! THESE ROUGH SHIFTS ARE ANNOYING. I ONLY HAVE 25K MILES ON MY TC SO IT CAN'T BE THE TRANSMISSION, IT'S THE COMPUTERS, PLEASE SEND OUT A NEW FIRMWARE TO FIX THIS! *TR
