2002 TOYOTA 4RUNNER Power Train 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.

I TOOK MY VEHICLE IN FOR A ROUTINE OIL CHANGE RECENTLY AND THE TECHNICIAN SAID THAT I HAVE SOME MAJOR RUST ISSUES ON MY REAR AXLE AND DRIVETRAIN. HE SHOULD ME WHEN IT WAS ON THE LIFT. HE EXPLAINED TO ME THAT THE BOLT AND CLIP THAN HOLDS THE BRAKE LINE DOWN ON THE REAR DIFFERENTIAL HAD RUSTED AND BROKEN OFF OF THE DIFFERENTIAL COVER. THE REAR DIFFERENTIAL IS NOW LEAKING GEAR OIL. THE TECHNICIAN ADVISED ME THAT IT IS TOO RISKY TO ATTEMPT TO REPAIR AS IT MAY CAUSE THE ENTIRE DIFFERENTIAL TO BE DAMAGED AND THE WHOLE REAR AXLE WOULD NEED TO BE REPLACED. THE TECHNICIAN ALSO SAID THAT IT IS A RISK TO DRIVE THE VEHICLE AND IS POSSIBLY UNSAFE TO KEEP DRIVING. HE STATED THAT IT IS UNKNOWN HOW MUCH LONGER I WOULD BE ABLE TO DRIVE IT UNTIL THE REAR AXLE CEASES.

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.

(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?

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.

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

RECENTLY PURCHASED THIS VEHICLE AND STARTED CLEANING IT, AFTER I DROVE IT HOME AND PRESSURE WASHED UNDERCARRIAGE, PIECES OF THE REAR DIFFERENTIAL STARTED FLYING OFF AND GEAR OIL STARTED RUNNING OUT OF HOLES. I HAVE A 1971 DODGE CHALLENGER WITH ORIGINAL REAR END THAT HAS NEVER BEEN IN GARAGE AND HAVE NEVER SEEN A REAREND RUST LIKE THIS. I'M REALLY WORRIED ABOUT HOW STRONG THE AXLE HOUSING STRUCTURE IS AND IF IT COULD POSSIBLE BREAK IN HALF WHILE DRIVING VEHICLE. *TR

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

Mileage: 72,000

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

TL* THE CONTACT OWNS A 2002 TOYOTA 4RUNNER. THE CONTACT STATED WHILE DRIVING 35 MPH, THE VEHICLE BEGAN TO LOSE POWER ABNORMALLY ACCOMPANIED BY THE ILLUMINATION OF THE CHECK ENGINE WARNING LIGHT. THE CONTACT LATER DISCOVERED THAT THE ALUMINUM RADIATOR AND THE BOLT THAT CONNECTED THE COOLANT AND TRANSMISSION FLUID TRANSFER WAS FAULTY CAUSING THE TWO FLUIDS TO COMBINE ABNORMALLY. THE CONTACT STATED SPOKE WITH SEVERAL MECHANICS THAT ADVISED HIM OF THAT THE TWO FLUIDS WERE COMBINING. THE VEHICLE WAS NOT REPAIRED. THE CURRENT AND FAILURE MILEAGE WAS UNAVAILABLE.

I AM THE ORIGINAL OWNER OF A 2002 TOYOTA 4RUNNER-SR5, SPORT EDITION WITH 74,600K MILES. IN NOVEMBER 2009, I EXPERIENCED THE SAME PROBLEM THAT'S BEING REPORTED BY OTHER TOYOTA OWNERS WHOSE VEHICLES ARE BEING RECALLED. THE ACCELERATOR PEDAL STUCK IN A PARTIALLY DEPRESSED POSITION ON ITS OWN AND QUITE SUDDENLY. THIS OCCURRENCE ONLY HAPPENED ONCE. THE ENGINE WAS RACING AT A VERY HIGH RPM AND MY REAR TIRES WERE SQUEALING LOUD ENOUGH TO DRAW ATTENTION FROM PASSERSBY. LUCKILY FOR ME I WAS SLOWLY PULLING INTO A PARKING SLOT. MY REACTION TO THIS SITUATION WAS TO PUT THE GEAR IN NEUTRAL AND APPLIED THE BRAKES. MY MAIN CONCERN IS IF THE ONGOING INVESTIGATION BY THE NHTSA AND TOYOTA WILL INCLUDE A LOOK-BACK AT EARLIER MODELS FOR THESE KNOWN PROBLEMS? AND, IF SO, WHAT IS THE MANUFACTURER'S RECOMMENDATION TO OWNERS' WITH EARLIER MODELS? *TR

I HAVE A 2002 TOYOTA 4 RUNNER WITH RUST OUT OF THE REAR DIFFERENTIAL HOUSING. I TOOK THE VEHICLE IN FOR REPAIRS ONLY TO DISCOVER THAT METAL WAS QUITE RUSTED AT THE REAR HOUSING AND INSTEAD OF A SIMPLE PART REPLACEMENT, THE WHOLE ASSEMBLY HAS TO BE REPLACED, A COSTLY REPAIR. I FOUND OTHER OWNERS WITH SIMILAR STORIES ONLINE. IS THIS A DEFECTIVE PART? I HAD TEMPORARY REPAIR WITH GRINDING, WELDING AND EPOXY WHICH FOR THE TIME BEING HAS CORRECTED THE LEAK BUT EVENTUALLY IT WILL REAPPEAR. *TR

CHECK ENGINE LIGHT CAME IN, IT WAS DIAGNOSED AS A 770 SHIFT SOLENOID-E AND I WAS TOLD BY TWO DIFFERENT EXPERTS THAT MY TRANSMISSION WOULD NEED TO BE REPLACED. THE TOYOTA 4-RUNNER WAS PURCHASED IN JANUARY 2008 FROM FOLSOM LAKE TOYOTA WITH 89,000 MILES AND CURRENTLY HAS 95,500 MILES ON IT. THE ESTIMATE FOR REPAIR WAS $2,300.00. *TR
