THE VEHICLES FRAME, IN THE LOCATION WHERE THE REAR LOWER CONTROL ARM BRACKET IS WELDED TO THE FRAME IS COMPLETELY ROTTED OUT. THIS POINT ON THE FRAME SECURES THE LOWER LINK OF THE REAR SUSPENSION. IF THIS BRACKET SEPARATES, AN ACCIDENT WOULD LIKELY OCCUR. THE REST OF THE VEHICLE IS RUST FREE AND THE FRAME IS NOT EXPECTED TO ROT WITHIN THE VEHICLES LIFESPAN. TOYOTA WAS CONTACTED AND REFUSED TO ASSIST WI REPAIRS. *TR

I JUST BOUGHT IT LESS THAN A MONTH AGO FROM AN INDIVIDUAL THAT IS A CAR SALES MAN FOR TOYOTA WEST IN COLUMBUS OH !! WANTING TO KNOW WHAT I CAN DO I HAVEN'T EVEN PUT A 1000 MILES ON IT !! *TR
WENT TO DO PREVENTIVE MAINTENANCE AND NOTICED MY FRAME IS RUSTED TROUGH ON PASSENGER REAR CLOSE TO AXLE. THERE IS A HOLE ABOUT 10-12 INCHES LONG. VERY VERY UNSAFE AND PROBABLY WON'T PASS INSPECTION. MAKES ME SICK TO MY STOMACH. WHY WON'T TOYOTA FIX THIS ISSUE. FROM WHAT I'VE SEEN IT'S COMMON ON THIS YEAR OF 4RUNNER. *TR
THE PASSENGER SIDE REAR FRAME SECTION IS RUSTED THROUGH. THE INSIDE PORTION OF THE FRAME IS COMPLETELY ROTTED AWAY. I HAVE CONTACTED TOYOTA IN REFERENCE TO THIS MATTER, AND THEY STATED THAT THEY INTEND TO TAKE NO ACTION IN THIS MATTER. *TR

I OWN A 1999 TOYOTA 4RUNNER, THE INSIDE FRAME RAIL IS ALMOST COMPLETELY RUSTED THROUGH NEAR THE REAR TRAILING ARM BRACKET . UPON INVESTIGATION I'VE CAME ACROSS MULTIPLE IMAGES, WEBSITES, AND FORUMS THAT SHOW THE EXACT SAME PROBLEM! HOW IS IT THAT A MANUFACTURER CAN HAVE THIS MUCH OF A WIDE SPREAD PROBLEM AND NOTHING BE DONE ABOUT IT! THEY FIXED THE PROBLEM ON THEIR TRUCKS AROUND THE SAME YEAR AND REPLACED THE FRAMES OR BOUGHT BACK THE VEHICLES, I UNDERSTAND THE FRAMES WHERE MADE IN DIFFERENT PLACES BUT THERE IS OBVIOUSLY STILL A PROBLEM! TOYOTA CANNOT EXPECT PEOPLE TO BELIEVE THAT THESE FRAMES WERE NOT DEFECTIVE WHEN THE EXACT SAME PROBLEM IS PREVAILING IN A MAJORITY OF THESE VEHICLES! HOW CAN A MANUFACTURER LIKE TOYOTA FIX SUCH SMALL ISSUES SUCH AS BLINKERS, INTERIOR LIGHTING, REFLECTORS ETC AND TOTALLY IGNORE SUCH A MAJOR SAFETY CONCERN AS THIS! I GUESS IT'S GOING TO TAKE A 4RUNNER WITH A FAMILY OF 4 TO CRASH INJURING OR KILLING ALL OF THEM TO MAKE SOMEONE STEP UP AND SAY WE HAVE A PROBLEM! SOMETHING MUST BE DONE! *TR
RECENTLY HAD NEW TIRES PUT ON CAR. I THEN HAD A MUFFLE REPAIRED, WAS NOT HAPPY AND TOOK TO TOYOTA DEALER TO HAVE DONE PROPERLY. I WAS TOLD THAT MY CAR WAS UNSAFE TO DRIVE AND IT COULD NOT BE REPAIRED. THE FRAME IS COMPLETELY RUSTED AND COULD CAUSE A MAJOR ACCIDENT. THE CAR LOOKS GREAT AND THERE IS LITTLE ISSUES WITH THE BODY…

RECENTLY HAD NEW TIRES PUT ON CAR. I THEN HAD A MUFFLE REPAIRED, WAS NOT HAPPY AND TOOK TO TOYOTA DEALER TO HAVE DONE PROPERLY. I WAS TOLD THAT MY CAR WAS UNSAFE TO DRIVE AND IT COULD NOT BE REPAIRED. THE FRAME IS COMPLETELY RUSTED AND COULD CAUSE A MAJOR ACCIDENT. THE CAR LOOKS GREAT AND THERE IS LITTLE ISSUES WITH THE BODY AND ENGINE. I WAS PLANNING ON GETTING ANOTHER 100,000 MILES ON THE CAR. I TOOK IT TO A GARAGE FOR A SECOND OPINION AND WAS TOLD THAT YOU COULD PUSH YOUR FINGER THROUGH THE FRAME. I NOW HAVE A PRETTY GOOD LOOKING CAR PARKED IN A DRIVEWAY WHICH IS UNSAFE TO DRIVE. I CANNOT BELIEVE THAT THERE IS NO RECALL OR WARNING ON THIS SAFETY ISSUE! I VOLUNTEER FOR A DOG RESCUE AND DRIVE ON THE HIGHWAY TO PICK UP AND DROP OFF THESE BEAUTIFUL DOGS NEVER KNOWING THAT I COULD HAVE ENDED THEIR LIFE AS WELL AS MINE AND OTHERS! UNBELIEVABLE! TOYOTA DID HAVE A FRAME RECALL ON THE TACOMA, WHY ARE THEY RISKING INNOCENT LIVES WITH NO WARNING!! *TR
WELL MAINTAINED 99 4RUNNER...ORIGINAL-EXCELLENT CONDITION PAINT AND NO RUST ON BODY PANELS. NOTICED AFTER EXAMINING THE UNDERSIDE THAT FRAME HAS RUSTED THROUGH IN MULTIPLE SECTIONS. SOME SECTIONS NEAR REAR SUSPENSION MOUNTS. IF MOUNTS BREAK LOOSE COULD RESULT IN SERIOUS ACCIDENT. *TR
