2017 Toyota Tacoma Suspension Problems

Mileage 64000: Vehicle went in for oil change and the mechanic noticed an issue with the differential mounts. The right bolt was corroded and broken leaving that side unsecured. The other bolt was heavily corroded also but still "intact". I had the support bolts, nuts and washers replaced on both sides for safety. These bolts were in a bad condition in relationship to a everything else under the vehicle. I want to make sure there isn't an issue with the bolts failing this early.

TWO MAJOR ISSUES ON MY TRUCK: 1) THE FRONT DRIVER SIDE SUSPENSION HAS BEEN SQUEAKING WHETHER THE VEHICLE IS IN MOTION OR NOT. 2) THE RADIO UNIT REBOOTS ITSELF RANDOMLY AND MULTIPLE TIMES DURING A SHORT DRIVE RENDERING THE BACKUP CAMERA USELESS.

VEHICLE HAS A VIBRATION ON DECELARATION BETWEEN 20 TO 0 MPH WITHOUT FOOT ON THE BRAKE AND VEHICLE OUT OF GEAR ON MANUAL TRANSMISSION. VEHICLE IS ALWAYS ON A STREET GOING STRAIGHT AND HAPPENS AT EVERY DECELARATION.

THE TRANSMISSION IN THIS TRUCK SHIFTS ERRATICALLY. THE FIRST SECOND SHIFT ALTERNATES BETWEEN EXTREMELY SLOW AND HARSH ENOUGH TO MAKE THE TRUCK BUCK AND SHAKE. BECAUSE OF THIS SHIFT ISSUE POWER APPLIED AT LOW SPEEDS IS INCONSISTENT. THE TRANSMISSION SEARCHES FOR GEAR AT HIGHWAY SPEEDS AND DOWNSHIFTS EXCESSIVELY. THE TRANSMISSION ISSUES STARTED AT APPROXIMATELY 2000 MILES ON THE VEHICLE AND ARE ONGOING. THE ISSUES OCCUR AT SPEEDS FROM 2MPH THROUGH 75MPH THESE ISSUES MAKE THE VEHICLE UNPREDICTABLE AND MORE DIFFICULT TO CONTROL. ADDITONALY THE U BOLTS HOLDING THE AXLE ONTO THE VEHICLE WERE NOT TORQUED PROPERLY FROM THE FACTORY. THE BOLTS WERE TORQUED TO APPROXIMALTY 30 FTLBS, NOT THE 52 FTLBS TOYOTA SPECIFIES, WHICH CAUSED AXLE WRAP ISSUES AND MADE THE TRANSMISSION ISSUES LISTED ABOVE WORSE.

TRANSMISSION CONSTANT HUNTING/ SHIFTING.

THE TRUCK SHIFTS INTO TOO HIGH OF A GEAR WHEN ATTEMPTING TO ACCELERATE BETWEEN 20-30 MPH., CAUSING ENGINE TO REV UP TO AND BEYOND REDLINE (5500RPM TO 6000RPM), WHICH IS EXTREMELY DAMAGING TO A NEW ENGINE. THIS RESULTS IN A 3 OR MORE SECOND DELAY OR STALL WHILE THE TRANSMISSION FINDS AN APPROPRIATE GEAR FOR THE CURRENT SPEED. MOST OF THE TIME, WHEN IT FINALLY DOES FIND A GEAR, IT IS OFTEN TOO LOW, RESULTING IN EXTREME ENGINE REVVING FOLLOWED BY COMPLETE LOSS OF POWER. THIS DELAY OR STALL ALMOST LEFT ME IN A SERIOUS ACCIDENT AS I PULLED OUT INTO THE INTERSECTION (UNDER NORMAL CIRCUMSTANCES), THE CROSS TRAFFIC DID NOT YIELD TO THE RED LIGHT. I HAD TO ACCELERATE QUICKLY FROM ABOUT 20 MPH, MEANWHILE, THE TRUCK'S TRANSMISSION STALLED AND WOULD NOT RESPOND. I NARROWLY AVOIDED BEING HIT. I HAVE TAKEN THE TRUCK IN NO LESS THAN FOUR TIMES IN THE LAST 12 MONTHS TO REPORT THE SAME COMPLAINT I HAVE DOCUMENTATION BUT CONTINUE TO BE TOLD THAT THE TRANSMISSION IS PERFORMING AT MANUFACTURED SPECIFICATIONS. NOT SURE WHAT THOSE SPECS ARE BUT NOTHING HAS BEEN DONE TO ADDRESS THE TRANSMISSION ISSUE THE TRUCK IS UNSTABLE WHEN DRIVING WITH HEAVY LOAD IN THE BED (NEVER EXCEEDING 1000LBS.). WHEN LOADED WITH 10- 90LB. BAGS OF CONCRETE (900LBS.), THE TRUCK FEELS EXTREMELY UNSTABLE. I WON'T DRIVE IT ON THE FREEWAY UNDER SUCH WEIGHT. THE MANUFACTURER STATED WEIGHT LIMIT IS TON (1000LBS.) AND YET WHEN FILLED WITH ONLY 900LBS OF CONCRETE THE LEAF SPRINGS ARCH, FULLY INVERTED UPSIDE DOWN, LEAVING THE TRUCK HIGHLY UNSTABLE AND UNRESPONSIVE. OF ALL THREE OF THE TOYOTA TRUCKS THAT I HAVE OWNED, INCLUDING THE 4 RUNNER, I HAVE NEVER SEEN THIS OCCUR IN THE LEAF SPRINGS NOR HAD STABILITY PROBLEMS CARRYING THIS TYPE OF WEIGHT. I DON'T FEEL COMFORTABLE DRIVING THIS VEHICLE DUE TO TRANSMISSION AND WEIGHT CONCERNS, AND FEEL IT IS NOT ONLY A SAFETY HAZARD TO MYSELF AS WELL AS OTHERS.
