2002 Toyota 4Runner Powertrain & Transmission Problems

WHEN THE CHECK ENGINE LIGHT IS ILLUMINATED, THE TRACTION CONTROL AND ANTI LOCK BRAKE FEATURES ARE AUTOMATICALLY DISABLED.

I PURCHASED THE 2002 4RUNNER IN 2014. AT THAT TIME, THE 4RUNNER ONLY HAD 79,000 MILES AND HAD BEEN CARED FOR METICULOUSLY. I HAVE TAKEN THE CAR IN FOR ROUTINE SERVICE OVER THE PAST 5 YEARS. UPON TAKING THE 4RUNNER IN DUE TO A VIBRATION AND CHECK OF THE DIFFERENTIAL, THE MECHANIC CALLED ME IN TO LOOK AT THE FRAME WHILE IT WAS UP ON THE LIFT. BELOW IN THE ATTACHED PHOTOS, THERE IS EXTENSIVE RUSTING OF THE REAR DIFFERENTIAL, AXLE AND FRAME. THE VEHICLE WAS STATIONARY AND THE ISSUE WAS FOUND DURING ROUTINE MAINTENANCE. THE RUSTED FRAME AND DIFFERENTIAL HAVE RENDERED THIS VEHICLE PRACTICALLY VALUELESS AND UNSAFE.

"TAKATA RECALL" FRAME RUSTED OUT FROM THE INSIDE OUT. LOOKING AT ON FRAME IT WAS AT LEAST 1.5 INCHES OF DIRT AND SMALL ROCK FROM MAINE ROADS AND THAN WHEN RAINED IT WAS JUST MUD THE BAD SPOT IS ON THE PASSENGER SIDE D BY TORSION BAR NO WAY TO DRAIN. ALSO REAR END DIFFERENTIAL GEAR COVER RUSTED OUT ON OTHER VEHICLES YOU REPLACED JUST THE COVER ON THE 4RUNNER I WAS TOLD TO REPLACE THE REAR END PRICE JUST FOR THE REAR END WAS $2500 THAN LABOR.

REAR DIFFERENTIAL RUSTED THROUGH

REAR DIFFERENTIAL COVERED RUSTING THROUGH.

MY FRAME IS ROTTING OUT. I JUST HAD TO REPLACE MY REAR AXLE BECAUSE IT HAD ALMOST ROTTED THROUGH. IT WAS ACTUALLY WEAPING GEAR OIL OUT OF SMALL HOLES THROUGH THE ROT. SOME OF THE FRAME HAD TO BE WELDED TO PASS INSPECTION.

TL* THE CONTACT OWNS A 2002 TOYOTA 4RUNNER. THE CONTACT STATED THAT FLUID WAS LEAKING UNDER THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC. THE TECHNICIAN DIAGNOSED THAT THE REAR DIFFERENTIAL HOUSING WAS RUSTED, LEAKED FLUID INTERMITTENTLY AND THERE WERE MULTIPLE HOLES TO THE POINT THAT THE COMPONENT MAY FRACTURE. THE REAR DIFFERENTIAL NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS NOT AVAILABLE.

REAR DIFFERENTIAL HAS RUSTED THROUGH, THE WHOLE THING HAS TO BE REPLACED BECAUSE THERE IS NO SEPARATE COVER THE REPAIR COST MAY BE HIGH. *TR

4 WHEEL DRIVE WOULD NOT WORK. VCS LITES AND CHECK ENGINE LITES ON. CAR ENGINE FILLED WITH BLACK SMOKE AND WAS TOWED TO REPAIR SHOP. DETAILS: DROVE ON FREEWAY AND LOST TRACTION AND THAN ON SHOULDER WITH ABOVE PROBLEM. DIFFERENTIAL REPAIRED. TWO DAYS LATER LITES ON AGAIN AND OIL LEAK. *TR

REAR AXLE ASSEMBLY ROT! NOW LEAKING ON REAR NON REPLACEABLE YOKE COVER. 1800-2000 DOLLAR FIX. TO MAKE THINGS WORSE AXLE ASSEMBLY HAS NO TAGS!!!! TOLD BY DEALER DOOR TAGS ARE OFTEN WRONG SO ORDERING RECYCLED (IF YOU CAN FIND ONE IN BETTER SHAPE) IS A GAMBLE!!!! HAS BEEN A DEPENDABLE TRUCK OTHER WISE BUT NOW IT SEEMS AS THOUGH THEY ARE PROFITING FROM THERE DESIGN FLAWS. *TR

(THERE WAS NO CATEGORY OFFERED FOR FRAME). DURING A RECENT AUTOMOTIVE SERVICE FOR BRAKES ON 9-26-13 FOR MY 2002 TOYOTA 4RUNNER, I WAS NOTIFIED OF A RUST PERFORATION IN THE FRAME BODY NEAR A REAR SUPPORT MOUNT FOR THE AXLE MAKING IT UNSAFE FOR OPERATION. THIS IS A SITUATION WHERE RUST FORMS IN THE INTERIOR OF THE FRAME AND WORKS ITS WAY OUT DESTROYING THE STRUCTURAL INTEGRITY OF THE VEHICLE. IT SEEMS THE SERVICE TECHNICIAN USED TO WORK AT A TOYOTA DEALERSHIP AND KNEW EXACTLY WHERE TO LOOK FROM HIS PRIOR EXPERIENCE WITH OTHER 4RUNNER FAILURES. THE TOYOTA DEALER INFORMED THAT THIS WOULD NOT BE COVERED. MY ?02 4RUNNER IS FROM THE SAME GENERATION (3RD) AND OF SIMILAR DESIGN TO THE TACOMA THAT WAS RECALLED FOR THIS THE DEALER INSTRUCTED ME TO CONTACT THE TORRANCE, CA TOYOTA CUSTOMER SERVICE AS HIS DEALERSHIP WOULD BE UNABLE TO ASSIST IN ANYWAY. IT WAS CLEAR THEY HAD ENCOUNTERED THIS BEFORE. THROUGH DISCUSSION WITH TOYOTA CA THEY HAVE NO INTENTION OF PROVIDING ANY MEANS OF RELIEF FOR A KNOWN AND WELL DOCUMENTED SAFETY PROBLEM. ONE REP DID COMMENT THAT THE TUNDRA AND SEQUOIA HAD BEEN RECENTLY ADDED TO THE RECALL BUT THE 4RUNNER WAS ?NOT YET? ON THE RECALL LIST. IT SEEMS TOYOTA VIEWS THE PRODUCTS TO BE DIFFERENT DUE TO THE BODY STYLE DIFFERENCES OR US VS JAPANESE BUILT PRODUCTS. THEY ALSO CLEARLY HAVE NO INTENTION TO ESCALATE INTERNALLY. I WAS INSTRUCTED TO FILE A COMPLAINT WITH NHTSA AND NTSB. RESEARCH ON LINE SHOWS THAT THERE IS A VERY WIDESPREAD ISSUE THAT TOYOTA IS CLEARLY CHOOSING TO IGNORE. WEB INFORMATION SUGGESTS THAT COLD CLIMATE AND THE AXLE BRACKET IN CLOSE PROXIMITY TO THE EXHAUST, ARE PRIMARY FACTORS. HOW CAN YOU RECALL ONE MODEL FOR A RUSTED FRAME DUE TO SAFETY BUT NOT ANOTHER? PERSONAL PHOTOS AVAILABLE. HUGE NUMBERS OF PHOTOS AND REPORTS AVAILABLE ONLINE - SEARCH " RUSTED FRAME 4RUNNER" OR SIMILAR. *TR

THE DIFFERENTIAL HOUSING IS RUSTING OUT AND IS SEEPING FLUID. IN ADDITION, THE FRAME IS DANGEROUSLY RUSTED, ESPECIALLY FROM THE REAR AXLE BACK. I HAVE BEEN TOLD BY A VERY REPUTABLE BODY SHOP IN THE AREA, THAT THE FRAME NEEDS TO BE REPLACED, BUT DUE TO THE SEVERITY OF THE RUST, THIS IS NOT PRACTICAL. TOYOTA IS REPLACING FRAMES ON THEIR TUNDRA PICKUPS DUE TO RUST, BUT REFUSES TO COVER 4RUNNERS, THOUGH THEY SHARE THE SAME FRAME. IF I DID NOT HAVE THE VEHICLE SERVICED BY THE DEALER REGULARLY, I WOULD BE UNAWARE OF THE DANGEROUS CONDITION OF THE FRAME. *TR

2002 TOYOTA 4 RUNNER. CONSUMER WRITES IN REGARDS TO VEHICLE GAS PEDAL MALFUNCTION. *SMD THE CONSUMER STATED AFTER STOPPING AT A STOP SIGN, HE ATTEMPTED TO MOVE FORWARD, BUT THE VEHICLE WOULD NOT MOVE. AFTER SEVERAL TRIPS TO THE DEALER, THE PROBLEM WAS FIXED. HOWEVER, THE CONSUMER DID STATE WHAT THE PROBLEM WAS.

MY 4RUNNER HAS 72000 MILES ON IT, AND I JUST REALIZED THE REAR DIFFERENTIAL HOUSING HAS RUSTED THROUGH. THE METAL IS SO THIN THAT THE FLUID IS LEAKING OUT THROUGH THE POURS OF THE METAL. I TOOK IT TO THE DEALER AND THEY SAID IT WOULD COST 3000$+ TO REPLACE THE ENTIRE REAR END. THERE IS NO OTHER RUST UNDER THE VEHICLE EXCEPT FOR THE PUMPKIN HOUSING. AFTER LOOKING AROUND ON THE INTERNET I FOUND THIS IS A COMMON PROBLEM, OF THE HOUSING NOT ONLY BEING TOO THIN OF METAL FOR THE APPLICATION, BUT LOW QUALITY STEEL THAT'S PRONE TO CORROSION. *TR

AFTER NOTICING A STRONG GEAR OIL ODOR AND SEEING THE ACTUAL GEAR OIL ON THE BACK THE OF THE VEHICLE I WAS ALARMED TO FIND OUT THAT THE REAR AXLE HOUSING HAD RUST PERFORATING THE REAR OF THE HOUSING. ONCE THE HOUSING WAS CHECKED BY A CERTIFIED MECHANIC AND TURNED AWAY DUE TO FEAR OF DESTROYING THE HOUSING, I REMOVED THE VEHICLE FROM THE ROAD. *TR

2002 4RUNNER SR5 4WD, 141K MILES, COMPLETELY RUSTED THROUGH REAR DIFFERENTIAL, BOTH REAR AXLE SEALS BUSTED OUT, DIFFERENTIAL HOUSING HAS SEVERAL PIN HOLE LEAKS AND IS THINNED OUT, THE ONLY FIX IS A COMPLETELY NEW REAR END, WHICH IS VERY COSTLY, I AM THE 2ND OWNER, I'VE OWNED A 99 4RUNNER THAT HAD THESE SAME REAR DIFFERENTIAL RUST ISSUES, THE RUST IS RIDICULOUS AND HAS DETERIORATED THE WHOLE UNDERCARRIAGE AND MY 4RUNNER IS GARAGE KEPT AND I WASH IT ALL THE TIME. I CAN'T BELIEVE TOYOTA HAS NOT BEEN HELD ACCOUNTABLE FOR THE RUSTING OUT OF REAR DIFFERENTIALS AND REAR AXLE ISSUES. *TR

THE REAR DIFFERENTIAL HOUSING HAS RUSTED THROUGH CAUSING ITS OIL TO LEAK OUT. *TR

2002 TOYOTA 4 RUNNER RUSTED OUT REAR AXLE HOUSING. REAR AXLE HOUSING LEAKS OIL DUE TO RUST EROSION ON THE REAR AXLE COVER. *TR
