2014 Toyota Tacoma Transmission Problems

You're hearing a groaning sound coming from your front differential (the component that helps distribute power to your front wheels) while driving between 15-55 MPH. Toyota has acknowledged this issue with a Technical Service Bulletin (TSB #0026-15), but they're only covering it under warranty rather than issuing a recall. The concern is that this noise indicates wear that could cause additional damage to the differential over time. Fixing this will likely involve inspecting and servicing the front differential, possibly replacing worn gears or bearings.

Your Tacoma's air switching valve has needed replacement twice in two years, and the vehicle keeps entering limp mode, which reduces performance and power. The dealer suggests you need to drive more than 5,000 miles annually to prevent this issue, but this seems like an unusual requirement for an emissions component. Fixing this will likely involve replacing the air switching valve again and possibly diagnosing why it's failing prematurely.

REAR DIFFERENTIAL IS SHOWING SIGNS OF LEAKAGE AND TOYOTA IS REFUSING TO COVER UNDER POWERTRAIN WARRANTY. PHOTOS ARE ATTACHED. DIFFERENTIAL CLEARLY SHOWS SIGNS OF OIL LEAKAGE WHICH CAN LEAD TO SAFETY CONCERN. THEIR DECISION TO NOT COVER UNDER WARRANTY IS NOT IN THE PUBLIC OR CONSUMER INTEREST.

AUTOMATIC TRANSMISSION SHIFTER UNABLE TO SHIFT -- BEGINNING IN 2017 (3 YEARS INTO THE NEW CAR), THE TRANSMISSION BEGAN TO EXHIBIT PERIODS WHERE IT WAS VERY DIFFICULT TO SHIFT. MOVING THE TRANSMISSION SHIFTER FROM STATIONARY TO ANY OF THE MOVING POSITIONS (R, D, 3, 2, 1) REQUIRED SIGNIFICANT STRENGTH. BEGINNING EARLIER 2019, CHECK ENGINE LIGHT CODE P0705 BEGIN COMING AND GOING ON THE DASHBOARD DISPLAY. THREE TRIPS TO THE DEALERSHIP THUS FAR HAS FAILED TO PROPERLY DIAGNOSE AND REMEDY THE ISSUE.

THE NEUTRAL SAFETY SWITCH PREVENTS THE SHIFTER TO ENGAGE THE DRIVE. I HAVE HAD THE NEUTRAL SAFETY SWITCH REPLACED ONE TIME UNDER THE MANUFACTURE WARRANTEE. I WILL HAVE IT REPLACED AGAIN TOMORROW APRIL 5, 2018. THE DEALER STAID IT IS CAUSED BY CORROSION. THE SAFETY ISSUE IS THAT YOU CANNOT CHANGE GEARS FROM REVERS TO DRIVE. IF IT FAILS TO ENGAGE, YOU MUST RUN THE GEARS UP AND DOWN AGAIN UNTIL IT DOES. SO BACKING OUT INTO TRAFFIC IS VERY DANGEROUS. DRIVEWAYS, PARKING LOTS AND STREETS, GOING FROM REVERSE TO DRIVE FROM PARKED TO DRIVE ETC. EVEN IF IT IS CAUSE BY SALT ON THE ROADS IN NORTHEAST, OHIO 1 WOULD NOT THINK IT NEEDED TO BE REPLACED EVERY 2 YEARS AND IF SO, THE MANUFACTURE SHOULD HAVE DISCLOSED THIS AS A REOCCURRING MAINTENANCE ITEM.

WHEN ATTEMPTING TO PULL OUT INTO TRAFFIC, WHEN I STEP ON THE ACCELERATOR, NOTHING HAPPENS. YOU HAVE TO PUSH THE SCCELERATOR ALMOST TO THE FLOOR BEFORE YOU GET ANY POWER. THIS IS VERY DANGEROUS, IN THAT I HAVE ALMOST BEEN BROAD SIDED NUMEROUS TIMES DUE TO THIS PROBLEM. . I HAVE REPORTED THIS PREVIOUSLY VIA REFERENCE NUMBER 10680961 BACK IN FEB OF 2015. THE NHTSA REPORT WHICH I RECEIVED WAS INCORRECT IN ITS DESCRIPTION OF THE PROBLEM. I HAVE ALSO REPORTED THIS TO TOYOTA, BIT THEY SAY THEY CANNOT DUPLICATE THE PROBLEM SO NOTHING HAS BEEN DONE. MY TRUCK NOW HAS APPROXIMATELY 24,000 MILES AND THE CONDITION HASBECOME MORE FREQUENT. I WANT TO GO ON RECORD WITH THIS COMPLAINT SO IF ANY OTHER DRIVERS ARE EXPERIENCING THIS CONDITION MAYBE TOYOTA WILL DO SOMETHING. MOST OF THE TIME I AM TRYING TO TURN INTO TRAFFIC WHEN THIS CONDISION HAPPENS.

TL*THE CONTACT OWNS A 2014 TOYOTA TACOMA. THE CONTACT STATED THAT WHEN THE BRAKE PEDAL WAS DEPRESSED, THE VEHICLE ACCELERATED INDEPENDENTLY. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 5,000. ....UPDATED 04/23/15 *BF UPDATED 11/12/15/2015*JS

WHEN OUTSIDE TEMPERATURE IS COLD (BELOW 10 DEGREES F) THE CLUTCH PEDAL STICKS FOR 1-2 SECONDS AT THE FLOOR WHEN PRESSED AND RELEASED. WHEN THIS HAPPENS, I CANNOT SAFELY MERGE INTO TRAFFIC. THE VEHICLE DOES NOT RESPOND AS I WOULD EXPECT. THE PROBLEM GETS WORSE AS THE TEMPERATURE DECREASES. AT -10 DEGREES F, THE VEHICLE IS ALMOST UNDRIVEABLE. ON 2/20/2015, ACTON TOYOTA OF LITTLETON, MA WAS ABLE TO REPLICATE THE PROBLEM ON MY VEHICLE. TOYOTA CLAIMS TO KNOW ABOUT THIS PROBLEM BUT DOES NOT HAVE A FIX. *TR
