2009 Toyota Tundra Suspension Problems

Frame perforation , front passenger side , bottom part of frame in critical point where weld is , in close distance from rack and pinion . At the dealer while servicing have asked to check the frame as there ben lots of concern from Tundra owners. I'm aware that early models have had frames replaced , perforation was found 7'' long by 3'' wide , vehicle was deemed NOT SAFE TO OPERATE . There is no action from Toyota on 2009's . Have called the Toyota brand rep to confirm and found that there is no action taken at this moment .There was no warning signs on dash as this is not part to be electronically monitored .This vehicle is well maintained and in its prime shape .Regularly washed with frame/chassis inhibitors (RASTEX) .Has only 146 K , for this model considering not broken in yet . I'm its original owner. Just spend a significant amount of $$$ on service and additional equipment, was looking for another 5 years +++ of use . Just purchased RAV 4 and COROLLA S hatchback for family members .TOYOTA is not offering to help at no coast . I know that if my track will reach 15 year mark there will be nothing to be concerned by Toyota .Fix is estimated parts and labor over $10 K , I do not have this kind of money at this time as just purchased 2 BN Toyota's . Please help !!!!! , thank You

TRUCK HAS EXTREME VIBRATION, BOUNCE AND OVERALL SHAKE AT FREEWAY SPEEDS AS FELT THROUGHOUT THE VEHICLE. THIS COMBINED WITH THE VERY LIGHT STEERING AND ACCELERATOR EFFORT LEADS TO A VERY UNSTABLE FEELING OF NOT BEING IN CONTROL OF THE VEHICLE. IT IS DIFFICULT TO MAINTAIN EVEN AND STEADY ACCELERATOR PRESSURE AND STEERING DIRECTION. DEALERSHIP HAS ROTATED AND BALANCED TIRES AND PERFORMED ALIGNMENT, BUT HAS MADE ZERO DIFFERENCE. *TR
