2018 Toyota Corolla Transmission Problems

Your 2018 Corolla experienced a whining noise and loss of acceleration power while driving at highway speeds, with the check engine light coming on. A mechanic diagnosed the problem using a diagnostic scanner and found multiple transmission-related error codes pointing to a faulty torque converter. Your CVT transmission will likely need to be replaced to fix the issue.

Your 2018 Corolla has experienced a recurring problem three times where the car suddenly limits speed to 40 mph while the engine revs high (around 4,000 RPM), even on the freeway. The transmission becomes slippery and noisy during these episodes, which you describe as scary. After waiting for the engine to cool, the car operates normally again until the problem repeats. A transmission inspection and potential fluid replacement or internal transmission repair may be needed to resolve this issue.

After vehicle is driven for approximately 15 mins or more and then comes to a long stop at a red light or drive thru line (while transmission is in drive and foot is on the brake), idle drops to 500rpm and car starts shaking as if it's about to die. Issue has been ongoing for years even before the fuel pump recall fix was performed but didn't start until around 25 thousand miles. Issue isn't the AC compressor cycling, it is not the secondary/auxillary cooling fans engaging, no check engine lights, no other symptoms. If it gets worse, it could cause the vehicle to completely stall in traffic posing a safety hazard. Shifting the transmission to neutral or park stops the issue. Shifting into neutral and then back to drive temporarily corrects the issue but then it re-occurs after at least 30 seconds or more. Many other 2017 and 2018 Corolla owners have reported this issue as well online and nobody has found the cause.

Had a recall on the fuel system causing the system to potentially stall the vehicle. Had the car service but still when doing cruise control its still doing the same thing by reving the engine to high on RPM to potentially stall the vehicle. Potential safety problem

IT HAS BEEN MULTIPLE TIMES WHERE I AM SITTING AT A RED LIGHT AND THE CAR SURGES FORWARD UNEXPECTEDLY. IT FEELS AS IF SOMEONE JUST REAR-ENDED ME. ONCE THIS HAPPENS AND YOU PRESS ON THE ACCELERATOR IT TAKES LONGER TIME FOR THE CAR TO COME TO SPEED. IT'S AS IF THE ENGINE JUST "BOGS" UP FOR A COUPLE SECOND.

TL* THE CONTACT OWNS A 2018 TOYOTA COROLLA. THE CONTACT STATED THAT WHILE THE VEHICLE WAS PARKED IN THE GARAGE, THE ELECTRIC FUEL PUMP STARTED ITSELF WHILE THE ENGINE WAS OFF. THE FAILURE RECURRED. THE CONTACT CALLED THE PRESTIGE TOYOTA DEALER (844-838-7075, LOCATED AT 1096 NJ-17, RAMSEY, NJ 07446) AND WAS TOLD TO BRING THE VEHICLE TO THE SHOP.

CAR RECENTLY IS NOT SHIFTING PROPERLY. DRIVES AT HIGH RPMS AND IF I ACCELERATE TOO QUICKLY SAY I GET UP TO 80 MPH ON HIGHWAY CAR WON'T SHIFT INTO NEXT GEAR THE RPMS SUDDENLY DROP ALL THE WAY DOWN TO UNDER 1000 AND QUITS ACCELERATING UNTIL IT JUMPS BACK INTO GEAR. HAVE TO LET FOOT OFF THE GAS FOR IT TO SHIFT AND CRUISE CONTROL HAS BEEN NOT FUNCTIONING PROPERLY EITHER.

THE RPM OF THE CAR JUMPS UPTO 4000 WHEN ATTEMPTING TO SLOW THE CAR ON DOWN HILLS. TOYOTA DEALERSHIPS ARE REFUSING TO ACKNOWLEDGE THE ISSUE BUT THERE ARE CASES MANY PEOPLE GOT THEIR CAR FIXED OR EXCHANGED. THIS PROVES THE ISSUE WHEN USING CRUISE CONTROL. THE IDEAL INTENT OF USING THE CRUISE CONTROL IS TO SAVE GAS MILEAGE AND EFFORT TO DRIVE THE CAR FOR LONG DISTANCES. I HAVE TO TRAVEL LONG DISTANCES TO WORK ON DAILY BASIS. I FEEL VERY UNCOMFORTABLE AND UNSAFE DRIVING THE CAR ON CRUISE. TOYOTA SHOULD ACKNOWLEDGE THE PROBLEM TO SAVE THE TRUST OF THE CUSTOMERS. THIS HAPPENS CONSISTENTLY. I AM TRYING TO CONTACT TOYOTA FOR THE ISSUE. I HOPE TO RECEIVE A POSITIVE RESPONSE.
