Structure

256 reports5 crashes1 fire
“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”

“I TOOK MY 4 RUNNER TO JOSEPH TOYOTA TO THE HAVE THE ROTORS CHECKED AND THE I WAS TOLD THEY FOUND RUST ON MY MAIN FRAME AND WOULD NOT SERVICE THE CAR. THEY SAID I NEEDED TO BUY A NEW CAR BECAUSE MINE WAS NOT SAFE. THIS IS THE ONLY CAR I HAVE AND I HAVE TAKEN GOOD CARE OF IT. I WAS SHOCKED THAT TOYOTA WOULD TURN ME AWAY AFTER PURCHASING 4 CARS FROM THEM. THEY TOLD ME THAT THE 4 RUNNER WASN'T COVERED BY THE RECALL FOR MAIN FRAME RUSTING LIKE THE TACOMA. I THINK WHEN TOYOTA KNOWS THIS PROBLEM EXIST THEY SHOULD HAVE TO TAKE RESPONSIBILITY FOR THE DEFECT. NOT EVERYONE CAN JUST GO BUY ANOTHER CAR. *TR”

Steering

21 reports4 crashes
“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.”

“HI, I HAVE A 2000 TOYOTA 4 RUNNER. IT HAS A LITTLE OVER 200K MILES AND I TOOK IT IN FOR SERVICE TO HAVE THE TIMING BELT AND WATER PUMP REPLACED. I DRIVE THE VEHICLE DAILY. THE MECHANIC DID NOT PERFORM THE WORK BECAUSE HE NOTICED THE FRAME HAD RUSTED THROUGH AND RECOMMENDED TO NOT DRIVE THE VEHICLE FOR SAFETY REASONS. HE STATED THAT IF THE FRAME DID BEND OR SEPARATE THE VEHICLE WOULD BUCKLE AND THERE WOULD NOT BE ANY CONTROL, ESPECIALLY ON THE EXPRESSWAY. THE MECHANIC RECOMMEND THAT I CHECK TO SEE IF THERE HAS BEEN ANY RECALLS. I DID CHECK TO SEE IF THERE WERE ANY RECALLS AND THERE WAS NOT. I WAS INFORMED THAT THE TOYOTA TUNDRA AND TOYOTA TACOMA HAD SIMILAR ISSUES WITH THE FRAME'S RUSTING THROUGH AND TOYOTA DID A RECALL/BUY BACK FOR THOSE VEHICLES. I WAS ON THE TOYOTA FORUM AND IT SOUNDS LIKE THERE ARE A LOT OF TOYOTA 4 RUNNERS IN THIS SAME CIRCUMSTANCE. I FEEL IF THERE ARE OTHER SIMILAR VEHICLES FROM TOYOTA HAVING THE SAME ISSUE, THEN THEY SHOULD BE INCLUDED IN THE RECALL/BUYBACK PROCESS. THANK YOU. *TR”
