2015 TOYOTA HIGHLANDER Suspension Problems

TL* THE CONTACT OWNS A 2015 TOYOTA HIGHLANDER. WHILE DRIVING APPROXIMATELY 40 MPH, THE SUBFRAME FRACTURED DUE TO THE REAR BOLTS ON THE FRAME BEING TOO TIGHT. THE VEHICLE WAS TOWED TO A DEALER WHERE IT WAS DIAGNOSED THAT THE REAR BOLTS WERE NOT PROPERLY INSTALLED FROM THE FACTORY ASSOCIATED WITH THE TORQUE. THE DEALER INSPECTED THE SUBFRAME AND STATED THAT IT DID NOT NEED TO BE REPLACED. THE DEALER REPLACED THE REAR HYBRID DRIVE MOTOR, REAR DIFFERENTIAL, THE ENTIRE EXHAUST SYSTEM FROM THE MOTOR TO THE MUFFLER, AND THE DRIVER SIDE SUSPENSION CONTROL ARM. THE CONTACT STATED THAT THE SUBFRAME NEEDED TO BE FURTHER INSPECTED AND REPLACED. THE CONTACT ALSO WAITED LONGER THAN TWO WEEKS FOR THE PARTS TO RECEIVE THE REPAIRS DUE TO THE FAILURE. THE VEHICLE WAS REPAIRED AND THE CONTACT TOOK THE VEHICLE TO ANOTHER DEALER WHO INSPECTED THE FRAME. THE SECOND DEALER, A MANUFACTURER'S TECHNICIAN,...

POPPING SOUND COMING FROM RIGHT FRONT SIDE WHEN BREAKING TO A STOP AT ALL SPEEDS. THE PROBLEM WAS FIRST NOTICED AT AROUND 2500 MILES AND THE CAR WAS TAKEN TO THE DEALER AT AROUND 2900 MILES. DEALER INSPECTED IT AND COULDN'T FIND WHAT THE PROBLEM WAS. THEN AS INSTRUCTED BY TOYOTA REPLACED THE RIGHT FRONT STRUT ASSEMBLY BUT THAT DIDN'T FIX THE PROBLEM. THE CAR WAS RETURNED TO ME AND I WAS TOLD THERE WERE NO SAFETY CONCERNS AND THAT TOYOTA WAS SENDING ONE OF THEIR TECHS TO TROUBLESHOOT, BUT THAT MAY TAKE A COUPLE OF WEEKS. IN THE MEAN TIME THE PROBLEM SEEMS TO BE GETTING WORSE.

CLUNKING NOISE FROM REAR END OF VEHICLE WHEN BRAKING, DEALER WAS AUTHORIZED TO CHANGE REAR AWAY BARS AND SHOCKS, NO FIX, NOW TOYOTA CORP., SAYS THIS IS NORMAL CHARACTERISTIC OF VEHICLE ? I DON'T FEEL SAFE DRIVING VEHICLE WITH NOISE, AND AS BRAKES FEEL SOFT ALSO.
