2005 Toyota 4runner Transmission Problems

Your 4Runner's undercarriage and frame have developed severe rust despite excellent maintenance and low mileage (under 140k miles). The rust has corroded critical components like power steering lines, making them too fragile to service safely. A mechanic has advised against driving the vehicle long distances due to safety concerns, limiting you to short trips at low speeds.

EXCESSIVE FRAME RUST AND UNDERBODY RUST. MOST WELD POINTS AND FRAME ASSEMBLY IS DEGRADING FROM RUST. TRANSMISSION COOLANT LINES HAVE CRACKED AND LEAKED.

STSTIONARY REAR AXEL HOUSING RUSTED -LEAKING OIL-INFERIOR STEAL JUST LIKE THE FRAME THAT WAS REPLACED

TL* THE CONTACT OWNS A 2005 TOYOTA 4RUNNER. WHILE DRIVING 70 MPH, THE VEHICLE LOST POWER. IN ADDITION, THE ACCELERATOR PEDAL WAS DEPRESSED, BUT THE VEHICLE FAILED TO ACCELERATE. THE CHECK ENGINE AND VSC WARNING LIGHTS ILLUMINATED. THE VEHICLE WAS TAKEN TO AN AUTO STORE WHERE A TECHNICIAN PULLED UP DIAGNOSTIC TROUBLE CODES. THE CONTACT SPOKE WITH A LOCAL DEALER WHO STATED THAT, BASED ON THE CODES PROVIDED, THE VEHICLE WOULD BE REPAIRED UNDER NHTSA CAMPAIGN NUMBER: 05V123000 (ENGINE AND ENGINE COOLING). THE VIN WAS NOT INCLUDED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 103,000.

TL* THE CONTACT OWNS A 2005 TOYOTA 4RUNNER. WHEN THE VEHICLE CAME TO A COMPLETE STOP, THERE WAS A TWO SECOND DELAY BEFORE THE VEHICLE JOLTED. THE CONTACT STATED THAT IT FELT AS THOUGH SOMEONE HAD REAR-ENDED THE VEHICLE. THE CONTACT STATED THAT THE FAILURE OCCURRED INTERMITTENTLY AND BECAME PROGRESSIVELY WORSE OVER TIME. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE DRIVESHAFT WAS LUBRICATED; HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 150,000.

I HAVE A 2005 TOYOTA 4RUNNER AND IT HAS A LOUD CLUNK IN THE DRIVETRAIN EVERY TIME I STOP.WHEN IT CLUNKS IT ALSO LUNGES FORWARD CAUSING A FEW CLOSE CALLS I HAVE ADDRESSED THIS ISSUE WITH TOYOTA AND THEY SAY IT IS A NORMAL OPERATING CHARACTERISTIC. THE PROBLEM OCCURS IN THE 03-06 4RUNNERS,TACOMAS AND LEXUS GX470 TOYOTA HAS A T.S.B ON THE LEXUS MODEL ONLY NOT THE TOYOTA 4RUNNERS OR TACOMAS WHICH MEANS AT LEAST TO ME THAT IT IS A DEFECT!!! I HAVE CONTACTED THE DEALERSHIP AND THEY SAY THEIR IS NO TSB SO THEY CANT DO ANYTHING I CONTACTED TOYOTA AND GOT NO RESPONSE. IF THEY WILL FIX THE LEXUS VERSION WHY NOT THE TOYOTA VERSION??? *TR

2005 TOYOTA 4-RUNNER SPORT EDITION. HAD CAR PARKED IN DRIVEWAY. CAR WAS IN PARK WITH NO KEY IN THE IGNITION. 4-YEAR OLD CHILD CLIMBED INTO CAR AND PUT CAR GEAR-SHFT INTO NEUTRAL (NO KEY IN IGNITION AND FOOT WAS NOT ON BRAKE PEDAL). CAR ROLLED OUT OF DRIVEWAY INTO A BUSY ROAD. ANOTHER CAR NEARLY HIT THE 4-RUNNER. DRIVER OF OTHER VEHICLE STOPPED AND HALTED OTHER TRAFFIC BY HONKING THEIR HORN. OWNER OF 4-RUNNER HEARD HONKING, CAME OUT OF HOUSE AND FOUND 4-RUNNER SITTING ACROSS THE ROAD WITH THE 4-YEAR OLD CHILD STILL IN IT. CONDITION OF PUTTING 4-RUNNER INTO NEUTRAL WITHOUT KEY OR FOOT ON BRAKE PEDAL WAS TESTED SEVERAL MORE TIMES AND FOUND TO BE REPEATABLE. *TR

THE VEHICLE RPMS WOULD GO UP BUT THE CAR WOULD BARLEY MOVE, OR WHILE DRIVING GOING TO ACCELERATE THE VEHICLE WOULD NOT GO FASTER TO ENGAGE IN TRAFFIC, CORROSION OF PINS IN THE TRANSMISSION WIRING HARNESS THAT CONNECTS TO THE ENGINE WIRING HARNESS. THIS HARNESS IS ALSO TIED TO THE ABS, TRACTION CONTROL. IT CAUSES THE VEHICLE TO BECOME UNSAFE WHEN DRIVING AS IF IT ACTS UP YOU CANNOT ACCELERATE AND SORT OF CHUGS ALONG. DANGEROUS IN ON RAMP AND TRAFFIC SITUATIONS. THIS ALSO CAUSED THE SOLENOID IN THE TRANSMISSION TO SHORT OUT AS IT WAS HANGING UP ON THE SHIFT WHICH CAUSED A CLUNKING SOUND. THE TRANSMISSION WIRE HARNESS WAS REPLACED WHICH SHOWED 3 CORRODED PINS. THE SOLENOID IN THE TRANSMISSION WAS ALSO REPLACED. *TR

WHEN BRINGING VEHICLE TO A STOP, THERE IS A VERY LOUD CLUNK THAT CAN BE PHYSICALLY FELT SHUDDERING THROUGH THE ENTIRE VEHICLE. MANY MANY TRIPS TO THE DEALER RESULTED IN NOTHING. THERE IS A TSB FOR THE LEXUS EQUIVALENT OF THE 4RUNNER WITH THIS PROBLEM. THIS MEANS THEY ADMIT THERE IS A PROBLEM, BUT REFUSE TO ACKNOWLEDGE IT ON NON-LEXUS VEHICLES. UNACCEPTABLE. IF THE DRIVESHAFT IS IMPACTING THAT HARD EVERY TIME THE VEHICLE STOPS, IT IS A MATTER OF TIME BEFORE EXCESSIVE WEAR WILL CAUSE A SAFETY ISSUE. *TR

WHEN COMING TO A STOP VEHICLE TENDS TO SHIFT INTO FIRST GEAR LATE, RIGHT AT STOPPING AND IT FEELS LIKE A BUMP OR SOMEONE HITTING YOU FROM BEHIND. THIS DEPENDS ON HOW FAST THE VEHICLE IS STOPPED. IF STOPPED FASTER, THE VEHICLE NEVER SHIFTS INTO FIRST GEAR AT STOPPING. AFTER THE BRAKE IS RELEASED THE VEHICLE FEELS AS IF SHIFTING FROM SECOND TO FIRST GEAR. MANUALLY DOWN SHIFTING THE VEHICLE IN ALL GEARS FEELS NORMAL EXCEPT FROM SECOND TO FIRST. THERE IS A HESITATION BETWEEN THESE GEARS, THE VEHICLE COAST AS IF IN NEUTRAL FOR ABOUT TWO SECONDS THEN SHIFTS INTO FIRST GEAR. THIS WEBSITE ALSO DESCRIBES THE "BUMP" FEEL FROM OTHER OWNERS, SEARCH FOR "BUMP" HTTP://TOWNHALL-TALK.EDMUNDS.COM/DIRECT/VIEW/.F0DACC5/175. *TR

EVERY SO OFTEN MY 2005 TOYOTA 4-RUNNER WILL LURCH FORWARD AT A STOP. ITS LIKE THE VEHICLE IS BEING REARENDED. THIS OCCURS WITHOUT WARNING AND AT RANDOM TIMES DURING A TYPICAL DAY. THE TRANSMISSION WILL ALSO LOCK IN 4TH GEAR IF WHILE DRIVING ON THE INTERSTATE THE VEHICLE SLOW SUDDENLY - THIS IS CORRECTED BY PULLING OFF THE INTERSTATE, SHUTTING DOWN THE VEHICLE AND WAITING A FEW MOMENTS. *TR

1. HAPPENED SINCE ABOUT 15-20K MILES ON MY 2005 4RUNNER (I'M THE FIRST AND ONLY OWNER). 2. OCCURS WHEN COMING TO A STOP, LARGE CLUNK SOUND AND VEHICLE JOLTS FORWARD RIGHT AFTER A FULL STOP. 3. NOTHING HAS BEEN DONE TO CORRECT THE FAILURE. EACH TIME THE TOYOTA DEALER SERVICE TECH TAKES IT FOR A RIDE THEY CANNOT REPLICATE IT, I WENT ONCE AND WAS NOT ABLE TO REPLICATE IT AT THAT TIME. HOWEVER, THERE ARE NUMEROUS ONLINE FORUM DISCUSSIONS ABOUT THE ISSUE (SEE THIS ONE: HTTP://WWW.TUNDRASOLUTIONS.COM/FORUMS/4RUNNER/53302-4RUNNER-V8-CLUNK-IN-DRIVETRAIN/). APPARENTLY A RECALL FIX FOR THE LEXUS 470 (SAME AS A TOYOTA 4RUNNER LIKE MINE) HAS BEEN PROVIDED FOR LEXUS OWNERS BUT NOT FOR TOYOTA OWNERS. THE PARTS TO SOLVE THE ISSUE ARE IDENTICAL. TOYOTA DEALER SERVICE DEPARTMENT STATED UNLESS TOYOTA MOTOR CORP. ACTUALLY ISSUES A RECALL AND PROVIDES DETAILS ON A FIX, THEY ARE NOT ABLE TO DO ANYTHING SINCE WE CANNOT REPLICATE IT WHEN THEY ARE SERVICING MY 4RUNNER. *TR

SEVERAL TIMES A DAY WHEN I COME TO A STOP IN MY 2005 4RUNNER I HEAR A CLUNK AND IT FEELS LIKE SOMEONE HAS JUST REAR ENDED ME. THIS HAS HAPPENED SINCE I BOUGHT THE VEHICLE AND IS GETTING WORSE. LEXUS HAS A TSB FOR THIS EXACT SAME COMPLAINT YET TOYOTA PRODUCTS DO NOT. WHY IS THAT? TSB#DL002-07. *TR

DRIVESHAFT CLUNKS AFTER COMING TO A STOP ALSO ON ACCELERATION FROM A STOP. *TR

IN GENERAL, WHEN I PULL UP TO A STOP I SOMETIMES FEEL A CLUNK. THEN, WHEN I START AGAIN, IT FEELS LIKE THE BRAKE RELEASE IS DELAYED WITH ANOTHER CLUNK. THERE'S A FEW LEXUS GX470 OWNERS (SAME ENGINE AND DRIVETRAIN AS 4RUNNER) THAT ARE COMPLAINING AT OTHER SITES. I'VE BEEN TOLD THE TWO PIECE DRIVESHAFT GETS AIR COMPRESSED INSIDE, AND WHEN THE COMPRESSION LEAKS OUT, YOU GET THE CLUNK. LEXUS IS APPARENTLY FIXING THE PROBLEM. *JB

WHILE THE CONSUMER WAS DRIVING 35 MPH IN HER 2005 TOYOTA 4RUNNER A BOOK SLID INTO THE SHIFTER KNOB AND KNOCKED IT OUT OF DRIVE AND INTO REVERSE. *NM ON TWO MORE OCCASIONS, THE VEHICLE WAS STOPPED ON A RAMP LIKE HILL AT A STOP LIGHT, THE CONSUMERS FOOT WAS OFF THE BRAKE, AND BEFORE THE CONSUMER COULD APPLY THE GAS A LOUD CLANKING NOISE FOLLOWED BY A RATCHETING SOUND AS THE VEHICLE DRIFTED BACKWARDS. *SC THE CONSUMER TEST DROVE ANOTHER VEHICLE AND THE SAME NOISE WAS HEARD, THE MECHANIC ALSO HEARD THE NOISE BUT STATED IT WAS NORMAL AND WAS NOT SURE OF THE SEVERITY OF IT. *JB
