2016 TOYOTA 4RUNNER Wheels Problems

Above 55 mph uncontrollable shaking of entire vehicle. The wheels have been balanced and rotated with no help.

75 MPH IMPACT ON INTERSTATE, 4 RUNNER COMPLETE LOSS. ENGINE PROTRUDED INTO FOOT WELL AND NOT A SINGLE AIRBAG WAS DEPLOYED. INJURIES INCLUDE - CONCUSSIONS, BROKEN NOSE, HEAD LACERATIONS, HEAD AND NECK PROBLEMS.

THE VEHICLE HAS HAD A MULTITUDE OF ISSUES. I AM ON MY 3RD DIFFERENT SET OF TIRES THIS YEAR (INCLUDING THE ORIGINAL TIRES). NO MATTER HOW MANY TIMES THE TIRES ARE BALANCED, THE STEERING WHEEL SHAKES RATHER VIOLENTLY AT CERTAIN SPEEDS. THE TIRES HAVE BEEN BALANCED AND RE-BALANCED (INCLUDING ROAD-FORCE BALANCED, ETC.). ON-LINE FORUMS INDICATE THAT MANY OTHER TOYOTA OWNERS ARE EXPERIENCING THE SAME ISSUE. ALSO THIS WEEK I HAVE LOST THE ABILITY TO STEER THE VEHICLE (THE STEERING WHEEL IS LOCKING AND BINDING UP). APPROXIMATELY 2 WEEKS AGO THE RIGHT FRONT CALIPER FROZE UP AND THE VEHICLE NEARLY WENT OFF THE ROAD. ALSO THE REAR DIFFERENTIAL WAS NOISY FROM THE DAY THE VEHICLE WAS NEW. TOYOTA EVENTUALLY REPLACED THE REAR DIFFERENTIAL (I BELIEVE A BAD PINION GEAR). SHORTLY AFTER THE REAR DIFFERENTIAL WAS REPLACED THE VEHICLE STARTED TO GO IN AND OUT OF 4-WHEEL DRIVE ON ITS OWN, AND...

PUT THE VEHICLE IN H4 MODE (4 WHEEL DRIVE). IN A STOP POSITION, TURN ALL THE WAY RIGHT, OR ALL THE WAY LEFT IF YOU PREFER. ACCELERATE, PUSH ON GAS PEDAL. PROBLEM: 1) THE CAR MOVES IN A CLUNKING MOTION. 2) FEELS LIKE YOU ARE DRIVING WITH EMERGENCY BRAKES ON - BUT NO BRAKES IS ON. 3) SMELLS VERY BAD TIRE BURNT SMELL. 4) IF TOYOTA DOESN'T FIX THIS PROBLEM, ITS GONNA COST MORE MONEY TO FIX WHATEVER IT CAUSES - GEAR SHAFT, ECT.. GETS GRIND OR DAMAGE. BROUGHT IT TO THE DEALERSHIP AND THEIR MECHANICS SAYS YOU CAN'T USE 4 WHEEL DRIVE ON DRY PAVEMENT. WHAT? ITS A 4 RUNNER! YOU CAN DRIVE 4 WHEEL WHEN YOU WANT TOO. BESIDES, THE PROBLEM EXIST ON WET PAVEMENT OR SNOW CONDITIONS TOO. HOW ARE WE SUPPOSE TO GET OUT OF OUR DRIVE WAY IF THIS FEATURE DOESN'T WORK DURING SNOW CONDITIONS....
