RUSTY FRAME, RUSTED BRAKE, TRANSMISSION LINES

EXCESSIVE VEHICLE VIBRATION. FROM REVIEW OF WWW.TACOMAWORLD.COM FORUMS THIS IS A FAIRLY COMMON OCCURENCE WITH 2ND GENERATION TACOMAS (2005 TO 2015). IT SEEMS TO STEM FROM THE SPLIT DRIVESHAFT MODELS (PRERUNNERS AND 4X4S). IN SOME CASES IT HAS RESULTED IN VEHICLES DROPPING THE DRIVESHAFTS. IN MY TRUCK, IN ONE DAY IT WENT TO FINE TO WHAT FELT LIKE THE WORST WHEEL IMBALANCE I HAD EVER FELT. I IMMEDIATELY HAD MY WHEELS BALANCE AND THERE WAS NO IMPROVEMENT. THAT'S WHEN I WENT TO THE FORUMS. ALSO, HTTP://WWW.TACOMAHQ.COM/3392/TOYOTA-TACOMA-DRIVELINE-VIBRATION-TSB-2005-2014/

A COUPLE OF MONTHS AFTER PURCHASING THE NEW 4 RUNNER LISTED ABOVE, I BEGAN TO FEEL A CLUNK FROM THE TRANSMISSION WHEN COMING TO A STOP. THE DEALERSHIP SAID THEY WERE AWARE OF IT BUT COULD DO NOTHING BECAUSE THERE WAS NO SERVICE BULLETIN PUBLISHED REFERENCING THE PROBLEM. THEY SAID A SERVICE BULLETIN EXISTED ON THE LEXUS GX470, WHICH USED THE SAME DRIVETRAIN. TO THIS DATE THE VEHICLE STILL HAS THE SAME PROBLEM, NOT ONLY CAN YOU HEAR IT BUT THE INERTIA ON OCCASIONS PUSHES THE VEHICLE FORWARD. SERVICE BULLETINS ARE 00207 AND 00106, NHTSA ID# ARE 10021759 AND 10021707. *TR

THE SECONDARY AIR INDUCTION PUMP (AIP) AND SWITCHING VALVES FAILED ON MY 2006 4RUNNER LIMITED WITH V8. THIS IS THE SAME ISSUE THAT IS SEEN ON TOYOTA SEQUOIAS AND TUNDRAS. TOYOTA HAS ISSUED A SPECIAL EXTENDED WARRANTY FOR THIS SYSTEM ON THOSE VEHICLES, BUT NOT ON THE 4 RUNNERS, EVEN THOUGH THE DEFECTIVE SYSTEMS / PARTS ARE THE SAME. TOYOTA CUSTOMER CASE # 1409160408. THIS IS A > $2000 REPAIR TO BASICALLY CLEAR THE CHECK ENGINE CODE AND ALLOW ME TO PASS STATE INSPECTION. I BELIEVE THERE SHOULD BE A RECALL ON THIS SYSTEM OR AT LEAST HAVE TOYOTA COVER ALL VEHICLES WITH THIS DEFECTIVE SYSTEM, NOT JUST CERTAIN HIGHER-VOLUME MODEL YEARS. *TR

I WAS DRIVING MY WIFE 2006 TOYOTA 4RUNNER SR5 APPROXIMATELY 55-60 MILES PER HOURS ON 88 WEST IN CALIFORNIA AND THE SUV EXPERIENCE SUDDEN ACCELERATION PASS 70 MILES PER HOURS. I THEN STEP ON THE BRAKES AS HARD AS I COULD BUT THE SUV CONTINUES TO ACCELERATE FASTER THAN 70 MILES PER HOUR. WHILE MY FOOT IS ON THE BRAKE PEDAL AT ALL TIME BUT THE SUV COULD NOT SLOW DOWN. THE SUV THEN STRUCK THE REAR OF A PICK UP TRUCK IN FRONT. AFTER THE IMPACT, MY SUV CONTINUED APPROXIMATELY A HALF MILE AND THEN I WAS ABLE TO SLOW DOWN AND BRING TO A STOP IN THE RIGHT LANE. TOYOTA DOWN LOAD THE DATA ON THE SUV BLACK BOX ON 3/18/2014 AND SENT A LETTER TO ME AND MY WIFE THIS WEEK STATING THAT THE GAS PEDAL IS NORMAL. *TR

DURING SNOWSTORM IN 4 WHEEL DRIVE MODE; 4 WHEEL DRIVE SYSTEM WOULD NOT ENGAGE DUE TO FAILURE OF ADD - AUTO DISCONNECTING DIFFERENTIAL ACTUATOR. THIS LED TO EXTREMELY DANGEROUS SAFETY HAZARD WITH VEHICLE SLIDING ACROSS OVERHEAD BRIDGE. NO WARNING OF FAILURE, JUST BLINKING 4 WHEEL DRIVE INDICATOR ON DASHBOARD. TOYOTA SHOULD BE ORDERED TO REPLACE THIS PART FOR FREE ON ALL 4 WHEEL DRIVE 4RUNNERS. THIS PART HAS ALSO BEEN OUT-OF-STOCK IN THE USA DUE TO EXTREMELY HIGH FAILURE RATE. NOTE: FAILURE OCCURS WHEN VEHICLE IS IN DRIVING MODE IN WINTER WEATHER WHICH REPRESENTS A MAJOR SAFETY HAZARD TO TOYOTA 4RUNNER DRIVERS AND OCCUPANTS. *TR

AFTER STOPPING THE REAR END WILL 'CLUNK' WHEN EITHER LETTING OFF THE BRAKES, OR UPON ACCELERATING. THIS WILL OCCUR ROUGHLY 1/10TH OF THE TIME REGARDLESS OR VARIATION IN BRAKING PRESSURE OR ACCELERATION. I'VE TRIED EVERY COMBINATION OF GENTLE TO HARD STOPS AND STOPS WITH LITTLE CHANGE IN THE FREQUENCY OF THE ISSUE. THIS ONLY STARTED TO OCCUR AFTER 53K MILES. THE DEALER TOLD ME THE 4RUNNER NEEDED MORE LUBE, THEIR FIX HASN'T STOPPED THE PROBLEM. MY CONCERN IS THE DRIVE-SHAFT IS BINDING, AND AT SOME POINT COULD FAIL. *TR

OWN A 2006 TOYOTA 4RUNNER. NOTICED BELTS HANGING UNDER CAR ONE MORNING. OPENED HOOD AND THERE WAS OIL EVERYWHERE, THE BELTS WERE SOAKED AND HAD DETERIORATED. TOWED TO DEALERSHIP. TOLD IT WAS A KNOWN OIL LEAK DEFECT NEAR CRANKSHAFT. HAD THE ENTIRE DRIVE TRAIN REBUILT AS OIL HAD DAMAGED EVERYTHING. COVERED UNDER WARRANTY. CAR ALSO LUNGES FORWARD WHILE STOPPED AT STOP LIGHTS, STOP SIGNS, ETC. DEALERSHIP COULDN'T RE-CREATE SO NOT AN ISSUE FOR THEM. *TR

THE CONTACT OWNS A 2006 TOYOTA 4RUNNER. THE CONTACT STATED THAT AFTER STOPPING AND RE ACCELERATING THE VEHICLES DRIVE TRAIN MAKES A "CLUNKING" NOISE. THE VEHICLE HAS BEEN TAKEN TO THE TOYOTA DEALER FOUR TIMES AND THE DRIVE TRAIN HAS BEEN LUBRICATED FOUR TIMES. THE FAILURE NOISE GETS LESS NOTICEABLE FOR A WHILE AND THEN RETURNS AFTER THE LUBRICATIONS. THE NOISE IS GETTING PROGRESSIVELY WORSE. A TOYOTA TECHNICIAN STATED THAT THEY ARE AWARE OF THE FAILURE BUT THEY CAN OFFER NO REMEDY. THE FAILURE MILEAGE WAS APPROXIMATELY 25,000. RD THE CURRENT MILEAGE 30,000. RD

I WAS BACKING OUT OF A PARKING SPACE, IN REVERSE, WHEN THE ENGINE BEGAN TO REV. I HIT THE BRAKES AND SHIFTED INTO NEUTRAL. IT REVVED AT ABOUT 4000 RPM FOR A FEW SECONDS, THEN SLOWED DOWN TO A SPEED FASTER THAN NORMAL IDLE. I PUT IT BACK INTO REVERSE WITH BRAKE FIRMLY APPLIED, AT WHICH POINT IT RETURNED TO NORMAL PERFORMANCE. *TR

SOON AFTER PURCHASING MY 2006 4RUNNER V8 4WD I WAS PULLING MY BOAT AND NOTICED WHEN I WAS COMING TO A TRAFFIC LIGHT AND BRAKING THAT THE ENGINE WAS INCREASING IN RPM AND IT BECAME VERY DIFFICULT TO STOP. HAD THE TRAFFIC IN FRONT OF ME NOT BEEN CLEAR THERE WOULD HAVE BEEN AN ACCIDENT. THIS HAPPENED SEVERAL MORE TIMES OVER THE NEXT FEW MONTHS, OFTEN WHEN PULLING THE BOAT BUT NOT ALWAYS. I LATER REALIZED THAT THE ROOT CAUSE OF THE PROBLEM WAS THE PROXIMITY OF THE GAS AND BREAK PETALS. WHEN I PULL THE BOAT, AND SOMETIME OTHER TIMES, I WEAR FLIP-FLOPS WHICH ARE FAIRLY WIDE AND FLAT. THE FLIP-FLOPS ARE WIDE ENOUGH TO ACCIDENTALLY BRIDGE THE TWO PETALS WHILE DRIVING. MY 2001 4RUNNER NEVER HAD THIS PROBLEM. I HAVE NOT HAD THIS ISSUE RECUR SINCE I STOPPED WEARING FLIP-FLOPS WHEN DRIVING THE 4RUNNER. THE ONLY REASON I AM REPORTING THIS IS THAT I HAVE READ OF SUDDEN ACCELERATION ISSUES WITH TOYOTA'S AND THOUGHT THIS INFORMATION MIGHT HELP THE INVESTIGATION. THIS PROBLEM APPEARED TO BE A SUDDEN ACCELERATION ISSUE SINCE THE RPM'S WENT UP AND THE BRAKES COULD NOT STOP THE VEHICLE. I DON'T KNOW IF OTHER TOYOTA'S HAVE THE SAME PROXIMITY ISSUE BETWEEN THE BRAKE PETAL AND GAS PETAL. WE HAVE NOT SEEN THIS SAME ISSUE ON OUR 2004 SIENNA. *TR

I OWN A 2006 TOYOTA 4-RUNNER AFTER ABOUT 40,000 MILES WE STARTED EXPERIENCING A CLUNKING SOUND AND THE VEHICLE WOULD LURCH FORWARD WHILE TAKING YOUR FOOT OFF THE BRAKE WHILE AT A COMPLETE STOP. I ADDRESSED THIS WITH MY LOCAL TOYOTA DEALER AND AT THE TIME THEY DIDN?T KNOW WHAT IT WAS. THIS PROBLEM PERSISTED FROM A ONCE AND AWHILE ISSUE TO DOING IT EVERY TIME. I SPOKE WITH ANOTHER PERSON WHO HAD A V8 AND THE SAME PROBLEM, TOYOTA FIXED HIS VEHICLE BY INSTALLING A NEW LEXUS DRIVELINE. ONCE I TOLD THE SERVICE CENTER ABOUT THEM FIXING A VEHICLE WITH THE SAME PROBLEM THEY EXPLAINED THEY HAVE BEEN HAVING ISSUES WITH THE DRIVELINE AND THE YOKE ON THESE VEHICLES. THEIR FIX WAS TO LUBE THE DRIVELINE ZERK FITTING. THIS WORKED FOR A FEW WEEKS, BUT THE PROBLEM PERSISTED. WE ARE WORRIED THAT THE CAR WILL EVENTUALLY LURCH FORWARD AND EITHER HIT ANOTHER VEHICLE OR PEDESTRIAN. SINCE MY VEHICLE IS A V6 THEY CAN?T SWAP THE DRIVELINE LIKE THEY DID WITH THE V8. I DON?T WANT TO BE LIABLE FOR A HITTING SOMEONE WITH A VEHICLE THAT IS NOT PERFORMING CORRECTLY. MY VEHICLE DRIVE TRAIN IS STILL UNDER WARRANTY, BUT I CAN?T GET ANYONE TO SAY THEY WILL HONOR THIS ISSUE AFTER I PASS MY WARRANTY PERIOD. I BELIEVE THIS IS A SERIOUS SAFETY DEFECT AND SHOULD BE LOOKED INTO AS SOON AS POSSIBLE. *TR

EVERY TIME I STOP AND START DRIVING I GET A CLUNKING SOUND FROM THE VEHICLE. IT ALMOST FEELS LIKE IM BEING REAR ENDED. THIS HAPPENS PRETTY MUCH EVERY SINGLE TIME I STOP AND TAKE OFF FROM TRAFFIC LIGHTS OR STOP SIGNS. *TR

TL*THE CONTACT OWNS A 2006 TOYOTA 4RUNNER. THE VEHICLE WAS PARKED IN THE DRIVEWAY WITH THE ENGINE RUNNING. THE CONTACT STEPPED OUT OF THE VEHICLE WITH THE CHILD IN THE FRONT PASSENGER SEAT. THE CHILD RELEASED THE GEAR SHIFT TO REVERSE, AND THE VEHICLE DRIFTED AND CRASHED INTO A HOUSE. THE CHILD WAS NOT INJURED. THERE WAS PROPERTY DAMAGE , ALONG WITH DAMAGE TO THE VEHICLE. THE VEHICLE HAS NOT BEEN REPAIRED. THE CONTACT STATED THAT THERE SHOULD BE A SAFETY MECHANISM ON THE GEAR SHIFT. THE FAILURE AND CURRENT MILEAGES WERE 11,500. UPDATED 09/10/08. *LJ THE VEHICLE SUFFERED MINOR DAMAGE. UPDATED 09/16/08. *JB

AT ABOUT 32,000 MILES MY TRUCK STARTED TO FEEL AS IF IT HAD BEEN REAR ENDED WHEN I WOULD STOP AT A STOP LIGHT. AT FIRST IT WAS VERY LIGHT, BUT IT HAS SINCE GOTTEN WORSE. I TOOK IT IN TO THE TOYOTA DEALER AND WAS TOLD THAT THEY LUBED THE DRIVE SHAFT. THE DRIVE SHAFT IS SEALED, SO I ASKED HOW THAT COULD POSSIBLY HELP AND HE HAD NO ANSWER OTHER THAN TO SAY JUST SEE IF IT FIXES THE PROBLEM. THE PROBLEM IS STILL THERE AND GETTING WORSE. MY CONCERN IS THAT IT WILL ACTUALLY LURCH FORWARD AND BUMP THE PERSON IN FRONT OF ME IF I AM CAUGHT OFF GUARD AND LOOSE MY FOOTING ON THE BRAKE. *TR

I OWN A 2006 TOYOTA 4 RUNNER WITH A CLUNG IN THE DRIVELINE. IT HAPPENS WHEN YOU STOP AT A STOP LIGHT, ESPECIALLY THE LONG ONES. YOU THINK A CAR HAS BUMPED YOU IN THE REAR BUT NO ONE IS THERE. IT IS VERY DISCONCERTING. IT DOESN'T HAPPEN EVERY TIME. INITIALLY THE DEALER THOUGHT THAT IT WAS DUE TO THE ANTILOCK BRAKES ACTIVATING. THEY WERE NOT SUPPOSE TO ACTIVATE UNDER 3 MPH BUT THE SPEEDOMETER WAS OFF ABOUT 2 OR 2 1/2 MPH SO THE BRAKES PROBABLY THOUGH THE CAR WAS MOVING WHEN IT WAS SITING STILL. MORE RECENTLY, IT DIDN'T HAPPEN WHEN I TOOK IT TO THE DEALER SO THEIR OFFICIAL POSITION WAS THAT CAN'T DUPLICATE THE PROBLEM. BUT THE SISTER VEHICLE WITH LEXUS, THE GX470, HAD A TECHNICAL SERVICE BULLETIN OUT ON IT. IT HAS HAPPEND FROM THE PURCHASE DATE ON 9/1/06. IT NOW HAS A LITTLE OVER 6,000 MILES ON IT. *AK

TL* - WHILE DRIVING HIS 2006 TOYOTA RAV4 AT 60 MPH THE CONTACT FELT A JERKING AS IF THE VEHICLE WERE STRUCK FROM THE REAR. HE BELIEVES THAT THE VEHICLE''S 4 WHEEL DRIVE ENGAGED CAUSING HIM TO LOSE CONTROL OF THE VEHICLE. THE VEHICLE SPUN SEVERAL TIMES AND FLIPPED OVER MULTIPLE TIMES COMING TO A REST ON THE VEHICLE''S ROOF. THE AIRBAG DID NOT DEPLOY. THE DRIVER WAS INJURED. THE CONTACT WILL HAVE THE VEHICLE, PICTURES, AND A POLICE REPORT AVAILABLE.

NEW 2006 TOYOTA 4RUNNER HAS 10,000 MILES, LEAKING OIL FROM REAR DIFFERENTIAL, I WAS TOLD IT WAS DEFECT OF THE SEAL FROM THE MANUFACTURER, I WAS TOLD THE SEAL HAS TO BE HAS REPLACED. NOW I AM WAITING SINCE THE PART HAD TO BE ORDERED. *NM

I HAVE A DRIVELINE VIBRATION ON MY 2006 TOYOTA 4RUNNER V8 SPORT MODEL, 4575 MILES, VIN [XX]. THE VIBRATION IS MOST NOTICEABLE WHILE DIVING AT HIGHWAY SPEEDS OF 72-74 MPH. THE VIBRATION CAN BE DESCRIBED AS A CYCLICAL DRONING VIBRATION AND CAN BE FELT ON THE DRIVER FLOORBOARD AND DEAD PEDAL, THE ACCELERATOR PEDAL, AS WELL AS SLIGHTLY ON THE STEERING WHEEL. THE VIBRATION IS MORE NOTICEABLE WHEN A LOAD IS PLACED ON THE ENGINE LIKE WHEN CLIMBING A GRADE. THE VIBRATION IS ALSO NOTICEABLE WHEN ACCELERATING FULL THROTTLE VERY HARD FROM A STOP. THE VEHICLE ALSO HAS A CLUNK THAT CAN BE FELT AND HEARD WHEN COMING TO A STOP. THE CLUNK IS ALSO PRESENT WHEN STARTING FROM A COMPLETE STOP AFTER REMOVING THE BRAKES. I HAVE HAD THE VEHICLE INSPECTED BY BOTH THE DEALER AND DISTRICT TOYOTA SERVICE MANAGER. BOTH OF THEM INDICATE THAT THIS IS "NORMAL" FOR THIS TYPE OF VEHICLE AND THE THEY WON'T DO ANYTHING TO FIX THE PROBLEM. I DON'T FEEL THAT EITHER OF THESE ISSUES ARE NORMAL AND FEEL THAT THE PROBLEM IS SAFETY RELATED AND SHOULD BE FIXED. *JB UPDATED 07/16/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
