2015 Toyota Corolla power train problems

“The problem started 11/12/2021. The car started jerking and dropping out of gear while driving. A mechanic changed the transmission fluid and filter thinking it may resolve the problem. It did not now getting a code P2757 indicating the torque converter clutch pressure control solenoid was failing. Toyota issued a bulletin dated October 20, 2018 on CK313 CVT P2757 valve body replacement. It’s on your website and also a software update for CVT transmission dated August 13,2018 also on your website. This car did not get the update or either bulletin. Toyota has had multiple problems with the control solenoid but no recall . There were no problems with warning lights or issues prior to the incident. A mechanic has assessed the problem . We have contacted Toyota dealership locally they have said no recalls on the car.”

“The contact owns a 2015 Toyota Corolla. The contact stated while driving at various speeds, the vehicle hesitated to accelerate with the accelerator pedal depressed. The contact stated that the vehicle loss motive power with the fuel, check engine, traction control, and oil level warning lights illuminated. The dealer was not made aware of the failure. The vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure and informed the contact that the VIN was not included in a recall. The approximate failure mileage was 105,000.”

“THE TRANSMISSION ON THE VEHICLE HAS A TITAL OF 19,752MILES AS OF 5/3/2021. THE VEHICLE'S TRANSMISSION HAS FAILED DUE TO A "BAD CYLENOID" IN THE TRANSMISSION. I AM A 90 YEAR OLD WOMAN WHO WENT TO MY PHYSICIANS OFFICE AFTER MY APPOINTMENT I GIT IN THE CAR AND ATTEMPTED TO PLACE THE CAR IN REVERSE WHEN IT FAILED TO MOVE. I AM THE ORIGINAL OWNER OF THIS VEHICLE AND WAS SHOCKED THAT THERE WAS A PROBLEM ESPECIALLY DIBCE I HAD JUST TAKEN IT TO THE DEALER FOR REGULAR MAINTENANCE . DURING THAT MAINTENANCE THERE WERE NO NOTED PROBLEM BOUGHT TO MY STTENTIO. HENCE I FELL THAT THIS IS A SEVERE MANUFACTURERES DEFECR. I'M CONCERNED THAT THERE IS A SERIOUS DEFECT AND RELATED ISDUES DUE TO THE DEDIGN OR MANUFACTURING OF THE CVT TRANSMISSION WHICH I UNDERSTAND IS A BIG ISSUE THAT HAS BEEN ENCOUNTERED IN TOYOTA'S 2014 TO 2019 LINE OF VEHICLES. WHILE IT SEEMS THAT NO RECALL WERE FORMALLY ISSUED, I BELIEVE THAT THERE IS A HUGE PROBLEM BASED ON THE FAILURE OF THE CVT TRAMSMISSION... GIVEN THAT THE NORMAL TRANSMISSION MILEAGE FOR THIS MODEL IS ~ 250K MILES SO I STRONGLY FEEL THIS SITUATION IS SUSPECT. I ALSO UNDERSTAND THAT VEHICLES WITH THE CVT TRANSMISSION ARE SUBJECT TO A SPECIAL…”

“WHEN DRIVING, MY 2015 COROLLA WITH A CVT TRANSMISSION WITH ~74,000 MILES, THE CAR WILL OFTEN NOT ACCELERATE, SOMETIMES AT HIGH SPEEDS ON THE FREEWAY OR LOW SPEEDS IN RESIDENTIAL AREAS. FOR EXAMPLE, ON THURSDAY, MARCH 25, I WAS DRIVING HOME FROM WORK WHEN I HAD TO SAFELY PULL OVER BECAUSE MY CAR WOULD NOT ACCELERATE. SINCE I WAS NOT ON A BUSY STREET, I WAS ABLE TO DRIVE HOME BUT AT A HIGHLY REDUCED SPEED. WHENEVER THIS OCCURS IT HAPPENS WHEN I PRESS THE GAS PEDAL. THE CAR EITHER LURCHES REPEATEDLY OR THE ENGINE REVS TO A HIGH RPM WITH OUT ACCELERATING. BASIC MAINTENANCE SUCH AS CHANGING THE OIL AND COOLANT AS REQUIRED WAS DONE, HOWEVER I AM NOT SURE WHAT MAY HAVE CAUSED THE ISSUE. WHEN I TOOK IT TO THE DEALER ON THE 27TH, I WAS ALSO NOT AWARE THAT THERE WAS A RECALL THAT WOULD HELP MINIMIZE WEAR ON MY CVT AND SINCE MY VEHICLE IS OUT OF WARRANTY, I AM STUCK WITH THE ONLY OPTION OF COMPLETELY REPLACING THE CVT TRANSMISSION. I SUSPECT THAT OTHER DRIVERS OF THE SAME VEHICLE MAY HAVE NOT BROUGHT THEIR CAR IN FOR THE RECALL AND MAY BE IN THE SAME POSITION AS ME. PLUS, I DON'T BELIEVE THAT A SOFTWARE UPDATE WOULD HAVE FIXED ANYTHING. MY CAR WOULD STUTTER AT A STOP A…”

“I WAS DIVING DOWN AN INTERSTATE AND AFTER EXITING TO A STOP, THE CAR WOULD BARELY GO AFTER TURNING LEFT. AFTER A FEW MORE MILES, THE CAR JUAT STOPPED. THE ENGINE WOULD STILL RUN BUT NO ACCELERATION. AFTER HAVING THE CAR TOWED AND INSPECTED, WAS TOLD I NEEDED A NEW TRANSMISSION.”

“TL* THE CONTACT OWNS A 2015 TOYOTA COROLLA. THE CONTACT STATED THAT WHILE DRIVING 55 MPH, THE VEHICLE JERKED AND LOSS MOTIVE POWER WITHOUT WARNING. THE VEHICLE WAS RESTARTED HOWEVER, THE FAILURE RECURRED. THE CONTACT STATED THAT THE FAILURE RECURRED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO WALTERS TOYOTA (30 WALTERS LN, PIKEVILLE, KY 41501) TO BE DIAGNOSED HOWEVER, THE MECHANIC WAS UNABLE TO RETRIEVE A DIAGNOSTIC TROUBLE CODE. THE VEHICLE WAS LATER TAKEN TO MANN TOYOTA (1811 US-23, PRESTONSBURG, KY 41653) TO BE DIAGNOSED HOWEVER, THE MECHANIC ALSO FAILED TO RETRIEVE A DIAGNOSTIC TROUBLE CODE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE BUT OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 70,000.”
