Truck which is a 4 wheel drive has a vibration in the steering wheel and floor board when applying the brakes. This vibration starts when speed gets to 30 mph and below.

Update from Jul 13, 2018: Took to dealership and they recognized the problem but did not know how to fix. They drove 2 brand new 4 wheel drive trucks on their lot and both had the same problem. They did not know how to fix so they called Toyota and they said they were unaware of the problem so they could not tell the dealership how to fix it. I have file a formal complaint with Toyota.

Buzzing vibration in the pedal, steering wheel, cabin, and almost everywhere. High frequency vibrations related with engine RPMs. Toyota has acknowledged the vibration (engine/exhaust harmonics/rpm related vibration) and does not have a solution/will not fix it until it gets bad enough to isolate issue. My hands and feet go numb after extended road trips so that is not great, seems like an issue to me (explained to Toyota to no avail). Toyota, if you fix this, you win. I have not traded it in yet but it's getting to the point that it needs to be fixed or it needs to be gone.

MY NEW 2018 FRED ANDERSON TOYOTA TACOMA WITH 3000 MILES HAS A BAD VIBRATION IN THE STEERING WHEEL AND FLOOR BOARD AT 2000 RPMS. I CARRIED IT TO THE FRED ANDERSON TOYOTA DEALERSHIP IN COLUMBIA S.C. AND CHARLESTON S.C. WHERE I PURCHASED IT FROM AND BOTH DEALERSHIPS IN COLUMBIA S.C. AND CHARLESTON S.C. TOLD ME THAT THEY DON'T KNOW WHAT IS CAUSING THE VIBRATION AND TOYOTA DOESN'T HAVE A FIX FOR IT. TOYOTA CUSTOMER SERVICE TOLD ME THAT ALL TOYOTA TACOMAS FROM 2015 TO 2018 HAS A BAD VIBRATION PROBLEM. SO BEFORE YOU PURCHASE THAT NEW TACOMA YOU SHOULD TEST DRIVE IT AT DIFFERENT RPMS AND SPEEDS.
