The frame is rusted almost in half a mechanic said it's not safe to drive it will kill someone. The car lot that is selling me the car said he can fix it but it's being held together by welds and c foam. He wants me to still pay for it. I've complained about not being able to drive over 45 without swaying badly and they keep doing stuff to it saying it's fixed and it's not. It's to dangerous to drive. I have a video of underneath but it won't let me upload it

We recently looked at this vehicle at Toyota of Ann Arbor car lot. After taking the vehicle to a private Professional Certified Car Inspector we were told that that the passenger side Frame had a catastrophic Crack that ran 7' from front to back and over the forward facing Rear Leaf Spring Shackle Support making the vehicle unsafe for any driving. They showed us the frame damage and showed us how wire mesh and foam spray had been used in an attempt to hide it. We were scared to drive it back to the dealer (we drove very slow). We informed them of the damage and they were very rude and asked us to leave. My only goal here is to insure that this vehicle is not put on the road were it could result in death or injury.

Section of frame broke and fell to the pavement. Vehicle bouncing and went off road causing damage to front driver side bumper, turn signal light housing, headlight. Extensive Back frame rusting has made vehicle dangerous. Frame has many soft spots. Both back shocks rusted and broken. Replace shocks but frame will eventually brake. This is my only vehicle. So, I will continue to drive and pray that this vehicle stays together and doesn't result in death. Front frame and suspension are also rusted and rusting. Please help !
Frame is rotted out. Mechanic lifted it on hoist and frame is rusted terribly and said not drivable.
The frame is rusted thru in many places that hold the rearend in the frame and along the side rails of this 4 Runner Toyota 2000, the suspionsion arm rusted and broke free from the frame.
I REPORTED A SERIOUS SAFETY ISSUE SEVERAL YEARS AGO WITH A DEFECTIVE FRAME WELD ON MY 2000 TOYOTA 4RUNNER, WHICH CAUSED MY REAR DIFFERENTIAL SUPPORT TO SEPARATE FROM THE FRAME WHILE DRIVING AT 55-60 MPH. THIS CAUSED A SEVERE, UNEXPECTED SWAYING OF THE VEHICLE BACK AND FORTH AND ALMOST COMPLETE LOSS OF CONTROL
TRAVELING ON INTERSTATE AT 65 MPH AND HEARD A "POP." VEHICLE STARTED SWERVING BADLY -- TOTAL LOSS OF CONTROL. REAR END WAGGING HORRIFICALLY NEARLY HITTING CARS IN OTHER LANES. MANAGED TO GET TO SHOULDER BUT COULDNT SEE WHAT WAS WRONG. GOT VEHICLE OFF AT EXIT AND TO GARAGE. WAS TOLD FRAME SNAPPED AND REAR END CONTROL ARM …

TRAVELING ON INTERSTATE AT 65 MPH AND HEARD A "POP." VEHICLE STARTED SWERVING BADLY -- TOTAL LOSS OF CONTROL. REAR END WAGGING HORRIFICALLY NEARLY HITTING CARS IN OTHER LANES. MANAGED TO GET TO SHOULDER BUT COULDNT SEE WHAT WAS WRONG. GOT VEHICLE OFF AT EXIT AND TO GARAGE. WAS TOLD FRAME SNAPPED AND REAR END CONTROL ARM NO LONGER ATTACHED REAR END TO FRAME. FRAME ROT EXTENSIVE. SCARY AS HELL. NO OTHER RUST ON VEHICLE. THOUGHT VEHICLE WOULD FLIP!
VEHICLE STARTED HANDLING POORLY. I HAD RECENTLY REPLACED THE REAR SHOCKS AND THOUGHT I NEEDED AN ALIGNMENT DONE. BROUGHT IT TO MY MECHANIC WHO POINTED OUT THAT MY REAR UPPER CONTROL ARM BRAKCET ON THE PASSENGER HAD ROTTED AND BROKEN, CAUSING THE SQUIRRELY HANDLING. SHORTLY AFTER, WHILE DRIVING HOME FROM WORK ON THE HIGHWAY AT ~7…

VEHICLE STARTED HANDLING POORLY. I HAD RECENTLY REPLACED THE REAR SHOCKS AND THOUGHT I NEEDED AN ALIGNMENT DONE. BROUGHT IT TO MY MECHANIC WHO POINTED OUT THAT MY REAR UPPER CONTROL ARM BRAKCET ON THE PASSENGER HAD ROTTED AND BROKEN, CAUSING THE SQUIRRELY HANDLING. SHORTLY AFTER, WHILE DRIVING HOME FROM WORK ON THE HIGHWAY AT ~70MPH, I HEARD A CLUNK AND THE TAIL END OF THE TRUCK STARTED JUMPING/SWERVING. TOOK BACK ROADS HOME AND ASSESSED THE PROBLEM. LO AND BEHOLD MY DRIVER'S SIDE UPPER CONTROL ARM BRACKET ENCOUNTERED THE SAME FATE. ROTTED AND BROKEN. MY VEHICLE'S FIRST OWNER WAS IN MINNESOTA BUT SINCE THEN IT HAS BEEN IN TEXAS WHERE THERE IS NO SALT ON THE ROADS. I'VE DONE WHAT I CAN TO SEAL AND PREVENT FURTHER RUST ON THE FRAME AFTER PURCHASE AND YET THIS STILL HAPPENS? MY TRUCK IS NO LONGER DRIVE-ABLE AS IT'S EXTREMELY UNSAFE TO HAVE MY REAR AXLE DISCONNECTED FROM THE FRAME. SO UNTIL I CAN MANAGE TO 1) FIND SOMEONE WILLING TO WELD MY FRAME 2) PAY FOR SUCH A SERVICE I AM WITHOUT A VEHICLE... I PAID $2000 FOR THIS CAR LESS THAN A YEAR AGO WITH ONLY 170K MILES ON IT.
