2012 TOYOTA TACOMA Power Train Problems

The contact owns a 2012 Toyota Tacoma. The contact stated that the undercarriage of the vehicle was significantly rusted. The TPMS warning light was illuminated. The vehicle was taken to the local dealer, where it was repaired under the warranty; however, the failure recurred. The dealer informed the contact that the rear bumper and brackets were rusted, and there was no recall or warranty coverage. The contact stated upon pulling into the driveway of the residence, the contact noticed a trail of fluid leak on the street. The contact stated that the transmission lines were fractured due to rust. The vehicle was taken to an independent mechanic, where the contact was informed that the vehicle was significantly rusted. The vehicle was not repaired. The manufacturer was contacted and a case was filed. The failure mileage was approximately 71,000.

Mileage: 71,000

My truck started having a vibration when driving around 45-55 mph. This problem first became noticeable when it had about 115,000 miles on it. Over time the speed that the vibration became noticeable at gradually increased. By 125,000 miles on the truck, it was vibrating hard between 60 and 70 mph. The dealership determined that the problem was that the drive shaft was out of balance and that it had to be replaced. They replaced the drive shaft, but this doesn't seem like a problem that should creep up with that relatively few miles on the vehicle, and I have read that if the drive shaft actually fails, it can severely damage the vehicle and potentially cause injury.

Drivetrain vibration and cricket chripping noise; likly coming from propeller shaft

WHEN ACCELERATING THE TRUCK LOST ALL POWER AND ACCELERATION. ENGINE LIGHT IS ON. ENGINE WILL NOT INCREASE RPM WHEN ACCELERATOR IS PRESSED. TRUCK WILL SLOWLY DRIVE BUT IS UNSAFE TO BE ON THE ROAD AS IT SLOWLY ACCELERATES UP TO 20-30MPH MAX. VEHICLE WAS MERGING INTO TRAFFIC FROM PARKING LOT ACCESS.

Mileage: 110,000

WHEN I'M DRIVING THE TRUCK BETWEEN 30 AND 40 MILES AN HOUR THE TRUCK FEEL LIKE WANTS TO STOP AND SAUNDS WUIRD I THINK IS THE TORQUE CONVERTER IS NOT DOING HIS JOB PROPERLY ALSO THAT SUSPENSION IS GETTING RESTLESS SO BAD AND SO QUICKLY AND THE CHATS ARE SO HARD SO I DON'T KNOW IF IT IS SOMETHING WRONG WITH IT OR IT'S JUST NORMAL IN THE CAR AND SAW THE THINGS I'VE BEEN CHECKING ON IT 2012 TOYOTA AND I HAD IT FOR THREE YEARS ALSO IT TAKES TOO LONG TO HEAT UP IN WINTER TIME

Mileage: 108,243

60,000 MILES. THREE YEARS AGO THE AIRBAG LIGHT CAME ON. WE BROUGHT IT AND PAID FOR DIAGNOSTICS BUT NO ANSWERS. NOW THE CHECK ENGINE LIGHT AND TRACK OFF ARE LIGHTING (NOT RELATED TO FIRST ISSUE) AND THE TRUCK IS IN SLOWDOWN MODE. WE REPLACED THE GAS-CAP BUT IT DIDN'T FIX THE ISSUE. DISAPPOINTED IN WHAT USED TO BE A QUALITY COMPANY.

CHECK ENGINE LIGHT WITH TRAC OFF LIGHT COMES ON. NO POWER. AIR IDOL CONTROL VALVE STUCK OPEN.

Mileage: 103,000

DURING NORMAL DRIVING, THE CHECK ENGINE LIGHT AND TRACTION CONTROL OFF LIGHT CAME ON AND TRUCK IMMEDIATELY WENT IN TO LIMP-HOME MODE. I HAD IT SCANNED FOR CODES AT THE LOCAL AUTO PARTS STORE AND IT CAME BACK WITH P2440 AND P2442 WHICH SEEMS LIKE A COMMON ISSUE WITH A VALVE IN THE SECONDARY AIR INJECTION SYSTEM. I QUICK GOOGLE SEARCH SHOWED THAT SOME 2012 TACOMA OWNERS ARE GETTING THIS COVERED UNDER A SPECIAL WARRANTY EXTENSION, SO I PUTTERED OVER TO THE TOYOTA DEALERSHIP EXPECTING TO HEAR THE SAME STORY, BUT THEY ARE TELLING ME THE ECM COMPUTER IS BAD. WHICH I AM TRYING TO GET CLARIFICATION ON SINCE I CAN'T FIND ANY ECM FAILURE ISSUES FOR THIS MAKE AND MODEL YEAR.

Mileage: 144,000

DRIVE TRAIN VIBRATION. TOYOTA HAS A WARRANTY ENHANCEMENT PROGRAM FOR THIS ISSUE THROUGH THE 2011 MODEL, BUT THIS IS A 2012 MODEL WITH SAME ISSUE. SITUATION OCCURS DURING ACCELERATION.

Mileage: 95,000

TL* THE CONTACT OWNS A 2012 TOYOTA TACOMA. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE FAILED TO ACCELERATE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO DAYTON TOYOTA (2291 US-130, DAYTON, NJ 08810, 732-329-9191), BUT THE FAILURE COULD NOT BE DUPLICATED. THE FAILURE RECURRED SEVERAL TIMES AND THE VEHICLE WAS TAKEN BACK TO THE SAME DEALER. THE TECHNICIAN DIAGNOSED THAT THE CLUTCH NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURES AND OFFERED TO COVER THE COST OF THE PARTS WHILE THE CONTACT COVERED THE LABOR COST. THE FAILURE MILEAGE WAS 33,000.

Mileage: 33,000

CHECK ENGINE LIGHT AND TRAC OFF LIGHT CAME ON. TRUCK WENT INTO "LIMP" MODE AND WOULD ONLY GO ABOUT 35MPH. CHECKED THE ERROR CODE AND IT WAS P2442 WHICH SAYS THE SECONDARY AIR INJECTION SYSTEM IS FAILING. TRUCK HAS ONLY 55K MILES ON IT AND HAS BEEN REGULARLY MAINTAINED BY TOYOTA DEALERSHIPS EVERY 6 MONTHS / 5K MILES. DEALERSHIP HAS SAID IT WILL BE $2023 TO REPLACE THE SYSTEM. THERE SHOULD BE A RECALL OR EXTENDED WARRANTY ON THIS INJECTION SYSTEM

Mileage: 55,000

I START UP THE TRUCK AND PULL OUT IN TO THE STREET. WHETHER AT AN INTERSECTION OR MAKING A TURN, I PUSH ON THE ACCELERATOR AND NOTHING HAPPENS. THE RPMS DON'T INCREASE, ENGINE MAKES NO SOUND - AND I AM LEFT SITTING IN THE MIDDLE OF THE ROAD. I PUSH THE ACCELERATOR TO THE FLOOR AND EVENTUALLY THE ENGINE COMES TO LIFE AND THE TRUCK MOVES FORWARD. HAPPENS MORE OFTEN THAN NOT WHEN THE VEHICLE IS "COLD" - WITHIN THE FIRST 20-30 MINUTES OF OPERATION. THE ACCELERATOR IS NOT LINKED DIRECTLY TO THE ENGINE THROUGH A CABLE BUT IS A DRIVE BY WIRE. I HAVE MAINTAINED MY TACOMA METICULOUSLY SINCE PURCHASE INCLUDING TUNE UPS, OIL CHANGES, ETC. I HAVE CLEANED THE MASS AIR FLOW SENSOR WITH NO CHANGE. THE PROBLEM STILL PERSISTS. IT IS VERY DANGEROUS TO BE IN THE MIDDLE OF AN INTERSECTION WITH A VEHICLE THAT HAS LOST POWER.

Mileage: 51,000

WHILE COMMUTING TO WORK THE ENGINE LIGHT AND TRACTION CONTROL LIGHT CAME ON, CAUSING MY TRUCK TO SLOW DOWN, VERY SLOW. IT WOULD NOT LET ME ACCELERATE AND DISABLED MY PROGRESS TO AROUND 2000 RPMS. THIS COULD HAVE BEEN A VERY SERIOUS OR A DANGEROUS SITUATION ESPECIALLY IF I WAS TOWING A LOAD OR IN A MAJOR TRAFFIC SITUATION. CODES - 2440 AND 2442 WERE THE CAUSES OF THIS SCARY ACCOUNT.

Mileage: 105,000

CHECK ENGINE LIGHT ON, TRAC OFF LIGHT ON, ENGINE POWER WEAK CHECK ENGINE CODE- P2441. THIS HAS BEEN A COMMON ISSUE WITH TOYOTA SUVS, AND TRUCKS! CAR IS PUT INTO LIMP MODE. EXTENDED WARRANTY ON TUNDRA WITH SAME PART PROBLEM. NOT TACOMA. SHAMEFUL AND DANGEROUS FOR TACOMA OWNERS.

Mileage: 61,000

I HAVE 27,000 MILES ON MY TRUCK AND THE REAR DIFFERENTIAL IS DEFECTIVE. I AM AFRAID IT WILL LOCK UP AT HIGH SPEEDS, 55 MPH + AND CAUSE AN ACCIDENT!! TOYOTA WON'T FIX IT

Mileage: 27,800

THE SECONDARY AIR INTAKE SYSTEM GOES OUT FAIRLY QUICKLY. MY VEHICLE IS AT 72,500 MILES. THIS CAUSES THE CAR TO GO INTO "LIMP" MODE WHICH MAKES THE CAR GO A MAXIMUM OF 40MPH. THIS CAN BE VERY DANGEROUS IF IT WERE TO KICK IN WHILE ENTERING THE HIGHWAY. IT IS AN EMISSIONS ITEM, BUT TOYOTA IS NOT COVERING IT UNDER THE EMISSIONS WARRANTY.

Mileage: 72,500

CEL CODE P2442,P2445 DEALERSHIP SAYS THE AIR SWITCHING VALVE NEEDS TO BE REPLACED. I HAVE 75K MILES ON TRUCK. DEALER IS CHARGING ME 1200$

Mileage: 75,000

CODE P2440 AND P2442. AIR INJECTION SYSTEM VALVES ARE STUCK OPEN (RELATED TO EMISSIONS CONTROL UNIT) WHICH CAUSES THE VEHICLE TO GO INTO 'LIMP' MODE ABRUPBTLY. THIS RENDERS THE VEHICLE UNDRIVEABLE, AND CAN OCCUR IN THE MIDST OF DRIVING CAUSING SERIOUS DANGER TO THE DRIVER AND FELLOW DRIVERS ON THE ROAD. TOYOTA IS UNWILLING TO COVER UNDER ANY POWERTRAIN OR EMISSIONS WARRANTY. THIS ISSUE IS PERVASIVE AMONG 2012 TACOMA OWNERS AND TOYOTA REDESIGNED THE SYSTEM AS EARLY AS 2013 WHICH IMPLICATES THEIR KNOWLEDGE OF SUCH A DEFECT.

Mileage: 75,000

2012 TACOMA WITH 37,00 MILES: WHILE LEAVING A PARKING LOT AND TRYING TO ACCELERATE ON TO A BUSY HIGHWAY, (60MPH SPEEDS), TRUCK WOULD NOT ACCELERATE AND "CHECK ENGINE" AND "TRAC OFF" LIGHTS ILLUMINATED. VEHICLE WENT INTO "LIMP MODE" AND WOULD NOT GO FASTER THAN 35 MPH. I HAD TO QUICKLY PULL OFF THE ROAD AS TO NOT CAUSE AN ACCIDENT. IF THIS HAD THIS OCCURRED WHILE TRAVELING AT NORMAL HIGHWAY SPEED (60 MPH+), WOULD DEFINITELY BE IN A WRECK DUE TO THE SUDDEN DOWNSHIFT AND DECELERATION. I TOOK VEHICLE TO LOCAL AUTO PARTS STORE AND RECEIVED THE CODE P2442: SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN BANK 2. FROM RESEARCHING, THIS IS A KNOWN PROBLEM WITH 2012 TACOMAS, AND HAD PREVIOUSLY BEEN AN ISSUE WITH OLDER TUNDRAS, WHICH TOYOTA ISSUED A TSB FOR. TOYOTA REFUSES TO REPAIR THIS UNDER WARRANTY (EITHER POWERTRAIN OR FEDERAL EMISSIONS) EVEN THOUGH THE FAILED PART IS DIRECTLY TIED TO THE EMISSIONS SYSTEM! THE SYSTEM IS USED TO PUMP ADDITIONAL AIR INTO THE EXHAUST MANIFOLD UPON STARTUP TO DILUTE THE OVER-RICH CONDITIONS THAT LEAD TO INCREASED POLLUTION. (HOW IS THAT NOT AN EMISSIONS RELATED PART?) THE FAILURE OR WARPING OF THE ONE-WAY CHECK VALVE CAUSES HOT EXHAUST GASES TO BACKFLOW INTO THE SOLENOID, AND MELTING THE GASKETS. THIS ENDS UP BLOCKING THE SEALING PLATE AND CAUSING IT TO REMAIN IN THE OPEN POSITION. THE DANGER IS THAT THE HOT EXHAUST IS THEN FED INTO A PLASTIC AIR PUMP CAUSING IT TO POTENTIALLY MELT OR CATCH FIRE! THE FACT THAT THIS FORCES THE VEHICLE INTO "LIMP MODE" IS ALSO A HUGE SAFETY CONCERN AS IT WILL NOT ALLOW THE VEHICLE TO TRAVEL ABOVE 35 MPH AND COULD LEAD TO SERIOUS ACCIDENTS IF TRAVELING AT HIGH SPEED ON THE INTERSTATE OR HIGHWAY DUE TO THE UNEXPECTED, SUDDEN DECELERATION. FAILED ASSEMBLY IS TOYOTA PART NUMBER : 25710-31020. THIS PART NUMBER HAS BEEN SUPERSEDED BY P/N: 25710-31022 AND TOYOTA CHARGES BETWEEN $1500-$3200 TO REPLACE. *TR

CHECK ENGINE LIGHT CAME ON, TRAC OFF LIGHT IS ON. MY TRUCK HAS NO POWER AND IS UNSAFE TO DRIVE. THE DTC IS P2442. SECONDARY AIR INJECTION SYSTEM SWITCH VALVE STUCK OPEN BANK 2. TOYOTA KNOWS THEY HAVE A EMISSIONS ISSUE. MY VEHICLE IS AT THE DEALERSHIP NOW.

Mileage: 73,000

WE JUST PAID TOYOTA A LITTLE OVER $2,000 TO REPLACE THE SECONDARY AIR INJECTION SYSTEM. THE SWITCHING VALVE WAS STUCK CLOSED ACCORDING TO TOYOTA. THIS IS A 4 YEAR OLD TRUCK. IT IS UNREAL TO SPEND THIS KIND OF MONEY THIS EARLY FOR THIS. THE TUNDRA HAS RECALLS FOR THIS SAME ISSUE.

Mileage: 105,000

TACOMA WENT IN "LIMP MODE" ENGINE LIGHT AND TRAC OFF LIGHT ILLUMINATED; CAUSE THE CAR TO BE EXTREMELY UNDER POWER. VEHICLE EXTREMELY UNDER POWER CAUSING TO BE DANGEROUS IN TRAFFIC. CODE P2442 SECONDARY INJECTION SYSTEM FAILURE; COMMON TO OTHER TOYOTA VEHICLES INCLUDING TUNDRA'S. TOYOTA ACTED RESUMABLE WITH TUNDRA'S WITH EXTENDING WARRANTY REPAIRING BUT AT THIS TIME REFUSES TO REPAIR KNOWN FAILURES IN TACOMA'S.

Mileage: 45,000

SECONDARY AIR INJECTION SWITCHING VALVE FAILURE STUCK IN OPEN POSITION CAUSING LIMP MODE IN THE TRUCK. TRUCK IS NOT ABLE TO GET TO SPEED ABOVE 40 MPH. THIS HAPPENED AS I WAS PULLING OUT OF MY NEIGHBORHOOD ONTO A STATE ROUTE WITH SPEED LIMIT OF 55 MPH AND CARS GOING WAY FASTER THAN THAT. THIS COULD POSE A DANGER IF SITUATIONS WHERE SPEED IT REQUIRED TO GET OUT OF THE WAY OF ANOTHER CAR. TRUCK ONLY HAS 57K MILES ON IT. THIS IS A SUPPLEMENTAL EMISSIONS SYSTEM AND SHOULD NOT CAUSE THE TRUCK TO BE USELESS IF FAIL.

Mileage: 57,000

MY 2012 TACOMA WITH 45,000 MILES GOT A CHECK ENGINE LIGHT AND "TRAC OFF" LIGHT WHEN I STARTED IT TO GO HOME. I WAS MERGING ONTO THE INTERSTATE AND UNABLE TO GO ABOVE 40 MPH. THIS WAS OBVIOUSLY NOT SAFE SO I EXITED AND TOOK IT TO A DEALER. THEY CITED TROUBLE CODES P2440 AND P2442 AND SAID THEY NEEDED TO REPLACE SECONDARY AIR INJECTION VALVE (PN 25710-31022) FOR A TOTAL COST OF $940! ACCORDING TO FORUMS AND THE NHTSA.GOV SITE, THIS IS A VERY COMMON COMPLAINT WITH THIS YEAR AND MODEL. I JUST BOUGHT THIS LAST JULY AND I NEVER EXPECTED TO HAVE TO REPLACE PARTS ANYTIME SOON.

Mileage: 45,100

AS I'VE READ FROM NUMEROUS OTHER 2012 TACOMA OWNERS ON TACOMAWORLD.COM, MY SECONDARY AIR INJECTION SWITCHING VALVE HAS FAILED AT 65K MILES. THIS SEEMS TO BE A RECURRING ISSUE WITH ALL 2012 SIMILAR TACOMA MODELS AND SHOULD ABSOLUTELY BE RECALLED AND REPLACED FOR FREE! UNTIL FIXED, MY TRUCK IS UNDRIVABLE, MEANING THE CEL LIGHT IS ON AND THE TRUCK WON'T GO FASTER THAN 30 MPH.

Mileage: 65,000

THIS DOESN'T HAPPEN ALL THE TIME BUT OCCASIONALLY WHEN THE TRUCK COMES TO A STOP AND THE BRAKE PRESSED THE VEHICLE WILL ACCELERATE WITH A SURGE AND FEEL LIKE SOMEONE HAS BUMPED YOU FROM BEHIND BUT THERE WILL BE NO ONE BEHIND YOU. I HAVE TAKEN THE VEHICLE TO THE DEALER AND THEY MADE SOME ADJUSTMENTS BUT I CONTINUE TO EXPERIENCE THE PROBLEM. THIS HAS HAPPENED SINCE I BOUGHT THE TRUCK. I PURCHASED THE TRUCK WITH 1200 MILES.

Mileage: 1,400

VEHICLE LUNGES WHEN YOU COME TO COMPLETE STOP, BETTER HOLD THE BRAKE WITH SOME FORCE ANY TIME STOPPED, TOYOTA SERVICE SAYS IT HAPPENS ALL THE TIME, ITS NORMAL !!

Mileage: 500

AT APROXIMATE 40 MPH AND AT A CONSTANT SPEED THE VEHICLE STARTS TO SHUTTER OR SHAKE, FEELS LIKE IT WANTS TO DOWN SHIFT OR UP SHIFT MAYBE ITS CONFUSED. DEALER COULD NOT DUPLICATE 2 TIMES

Mileage: 50,000

MY 2012 TACOMA IS NOT SHIFTING PROPERLY. IT IS SHIFTING VERY HARD AND A BIT ERRATIC WHEN DRIVING, AND WHEN I AM COMPLETELY STOPPED AT A LIGHT, THE TRUCK WILL SOMETIMES VIOLENTLY SURGE FORWARD MAKING IT FEEL LIKE ANOTHER VEHICLE HAS HIT ME FROM BEHIND. IT DOES NOT HAPPEN ALL THE TIME, BUT IT SEEMS TO HAPPEN MORE WHEN IT IS COLD. I TOOK IT TO THE DEALERSHIP ONLY TO BE TOLD THEY COULD NOT REPLICATE IT, AND THIS IS NORMAL FOR A TOYOTA. THE DEALERSHIP ALSO SAID THAT TOYOTA IS AWARE OF THIS, ALL TOYOTAS DO IT (EVEN THE BRAND NEW ONES), AND NOTHING CAN BE DONE. MY TRUCK IS STILL COVERED BY THE TOYOTA 5 YEAR WARRANTY AND THE LIMITED LIFETIME WARRANTY OFFERED FROM THE DEALER WHEN I PURCHASED IT. I FEEL LIKE THEY ARE NOT HONORING THEIR WARRANTY. IF THIS IS TRUE AND TOYOTA IS NOT CORRECTING THESE ISSUES, GUESS I WON'T BE BUYING THAT 2015 4-RUNNER I REALLY WANT! *TR

Mileage: 4,000

I WAS APPROACHING A STOPLIGHT AT A DOWNWARD ANGLE AND WHILE APPLYING THE BRAKE THE VEHICLE BEGAN TO SHAKE VIOLENTLY. I WAS GOING APPROX. 15PMH WHEN IT STARTED AND IT DIDN'T STOP SHAKING UNTIL I GOT DOWN TO ABOUT 5 MILES PER HOUR. I TOOK IT TO THE DEALERSHIP THAT DAY AND EXPLAINED THE PROBLEM TO THEM. THEY GOT THE VEHICLE TO REPRODUCE THE VIBRATIONS AND I HAVE PAPERWORK STATING THIS. IT HAS BEEN A FULL YEAR LATER AND THEY HAVEN'T REPAIRED IT YET. THEY CONTINUALLY TELL ME PARTS ARE BEING DESIGNED. JUST WAIT. THAT'S ALL THEY KEEP SAYING. I FOUND OUT THAT THEY MADE A FIX FOR THE V6 MODEL WITHIN 7 MONTHS, BUT THEY DIDN'T HAVE ENOUGH COMPLAINTS AGAINST THE 4 CYLINDER MODEL TO WARRANT REDESIGNING PARTS. I WAS TOLD THIS BY THE SERVICE TECH AT THE DEALERSHIP. *TR

LOUD WHINNING NOISE FROM UNDER VEHICLE AT SPEEDS BETWEEN 30MPH AND HIGHER. *TR

Mileage: 20,950

THERE IS A VIBRATION IN THE ENTIRE DRIVE TERRAIN WHEN ACCELERATING FROM A STOP. THE VIBRATION ONLY OCCURS FROM A STOP AND BETWEEN 5-20 MPH. THIS WAS FIRST NOTICED IN MARCH OF 2013 AND THE DEALER (MIDDLE TOWN TOYOTA) AND US CORPORATE TOYOTA WERE MADE AWARE, BUT WAS TOLD NOTHING CAN BE DONE. AS OF TODAY, THE VIBRATION APPEARS TO BE GETTING WORSE. THERE HAS NOT BEEN ANY LOSS OF CONTROL YET OF MECHANICAL FAILURES, BUT WITH THE VIBRATION GETTING WORSE, IT IS ONLY A MATTER OF TIME BEFORE FAILURES START OCCURRING. *TR

3-5-2013 TACOMA 2012 TRD 4X4 AUTOMATIC NEW, I NOTICED A VIBRATION ON ACCELERATION IN 1ST GEAR THROUGH 2ND GEAR IN THE FIRST FEW DAYS OF PURCHASE. HOWEVER, BECAUSE OF MY JOB TRAVEL AND JUST BEING LAZY I NEVER DISCUSSED THIS ISSUE UNTIL RECENTLY. THE 1ST TIME I BROUGHT IT TO MY DEALER WAS 31 JAN 2013 13,433 MI. THE DEALER ACKNOWLEDGED THE VIBRATION AND SAID TOYOTA WILL ATTEMPT TO FIX THIS PROBLEM WITH A THREE TIER FIX. 1. THEY ORDERED ENGINE MOUNTS PER TSB. 2. FEB 2013 I BROUGHT THE VEHICLE BACK THEY INSTALLED THE MOUNTS, DID NOT FIX THE PROBLEM. AS PART OF THIS TIER FIX, WHILE IN FOR REPAIR THEY ALSO REPLACED REAR SPRING ASSY. RIGHT & LEFT AND THE FINAL STEP 3. REPLACING STEERING WHEEL DAMPER SHA PER TSB. THE DEALER SAID ALL THIS DID NOT HELP. 28 FEB 2013 14,325 MI, I RETURNED AFTER PUTTING MORE MILES ON THIS TROUBLED VEHICLE. THIS TIME THEY REMOVED THE DRIVE SHAFT AND DROVE THE VEHICLE IN 4WD AND VIBRATION GONE. THEY INSTALLED A DRIVE SHAFT FROM A NEW TACOMA 2013 AND THE VIBRATION RETURNED. THEY SAID THEY CREATED A TAS CASE #. THE ( PRODUCT ENGINEER) ?? SAID THIS VIBRATION IS NORMAL AND CANNOT BE FIXED AT THIS TIME AND IS UNDER REVIEW. I MUST SAY THAT MY DEALERSHIP HAS BEEN VERY ACCOMMODATING KUDOS-KUDOS. I FEEL THAT ANY VIBRATION IN THE DRIVE TRAIN OF ANY VEHICLE CANNOT BE CONSIDERED NORMAL. THIS PROBLEM HAS BEEN WITH TOYOTA FOR A WHILE SO IT SEEMS AND I ASK WHY, WHY,WHY. TOYOTA KNOWS THE ABOVE FIXES DO NOT FIX THE PROBLEM IN ANY WAY. SO WHY ARE THEY STILL DOING IT ??

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

Mileage: 90

AT 300 MILES I NOTICED UPON DOWNSHIFTING ( I BELIEVE 3-2 OR 2-1) A RUMBLESTRIP VIBRATION FEELING. I TOOK THE TRUCK TO THE DEALER AND THEY SAID IT WAS NORMAL. IT STILL OCCURS EVERYTIME I DOWNSHIFT (SOMETIMES STRONGER FEELING THEN OTHER TIMES) I RESEARCHED PREVIOUS YEARS WITH THE SAME COMPLAINT.. IT CANT BE HEALTHY FOR THE TRANSMISSION CLUTCHES. I NOW HAVE 1300 MILES...STILL HAPPENING...ANY THOUGHTS? *TR
