2019 Toyota Tacoma Powertrain & Transmission Problems

The transmission cooling line in my 2019 Toyota Tacoma was never installed by an authorized repair shop following an accident. This critical component failure led to the transmission failing just 1.5 hours after I retrieved the vehicle from the shop. My safety was compromised, as the failure occurred while driving at highway speeds, without any warning lights or messages indicating an issue. The failure has been confirmed by the dealership (MotorWorld Toyota) currently inspecting my vehicle. The shop responsible for the initial repairs has taken liability for missing the installation of the transmission cooling line. My insurance company (GEICO) has been involved but is delaying total loss consideration. No warning lamps or messages appeared before or after the transmission failure, which is highly suspicious. This negligence has caused severe damage to a vital component of my vehicle, and I question the overall integrity of the repairs.

This 2019 truck feels like it just doesn’t want to go. It struggles to go up ANY hill no matter how small. The engine jumps feels like it’s got a heart beat while riding. The gas mileage is horrendous and awful the 2015 was all around a better truck I read somewhere that Toyota recalled a bunch of 2019 trucks for a gas line rip was causing fires and whatever else. I thought for sure it had to be my trucks issue bc that would absolutely explain why it’s running so weird and ragged. The poor thing … I’m very worried about it.

The engine part “Coolant bypass joint” failed, started leaking coolant at 44k miles, because it was made of inferior plastic material, unlike the same part used in the same 3.5L V6 engines in the Lexus vehicles, which are made of aluminum. This is a widespread failure since 2016 model years, and Toyota refused change the design or manufacturing material of the part, or to repair it under warranty. The part number for this failed part is 16356-31051.

Occasionally, my Tacoma jerk at lower speeds of 20 to 5 mph. Also, random I hear a click sound on brake.

A full replacement of the cylinder 1 head and valves at only 60,000 miles, repair estimate of $8000

Took my car for Regular maintenance and they did tire rotation and etc after that the car was driving kind of off now its just acting up started shaking and jerks like shutters and stuff feels vrry unsafe

TRUCK STARTING LUNGE FORWARD WHILE IN HIGHWAY GOING SPEED LIMIT ALMOST LIKE IT'S SLIPPING GEARS

NOTICEABLE VIBRATION WHEN SLOWING DOWN. IT HAPPENS BETWEEN 40MPH TO 0 MPH. SLIGHT VIBRATION WHILE ACCELERATING FROM A STOP TO AROUND 45MPH. ENGINE ALSO SURGES, AND HAS TROUBLE FINDING THE CORRECT GEAR WHILE ACCELERATING OR DECELERATING. WHEN PUT IN NEUTRAL WHILE SLOWING DOWN, THE VIBRATION IS NOT FELT AT ALL. TOOK THE TRUCK TO THE DEALERSHIP, EXPLAINED THE ISSUES. WAS TOLD NOTHING WAS MECHANICALLY WRONG. THEY ROTATED MY TIRES AND DID A FRONT END ALIGNMENT. THE TRUCK HAS JUST OVER 12K ON IT ! THIS IS A DISASTER IN THE MAKING.

Transmission shifts when it should not shift! It also jerks when accelerating and maintaining speeds. While in cruse control the truck drops in 20mph in speed really concerning when it would cause a bad wreck while it drops it constantly still jerks and it also floors the truck to get back up to the preselected speed and transmission jerks and studders and drops and speeds back up and so it sounds like it could blow up from it flooring and dropping in speed and flooring it in cruse control This needs fixed and worked out! Transmission shouldn’t be jerking or hunting for gears

MY VEHICLE (VIN# [XXX]) HAS NOT HAD SAFETY RECALL ADDRESSED BY MY LOCAL DEALERSHIP. THE RECALL WAS INITIATED ON 28 OCTOBER 2020. THE LOCAL DEALERSHIP HAS HAD MORE THAN A MONTH TO MAKE A PLAN TO FIX THE PROBLEM AND HAS RESPONDED TO MY REQUEST BY STATING THAT PARTS ARE NOT YET AVAILABLE AND FEEL I SHOULD CONTINUE TO OPERATE MY VEHICLE IN ITS CURRENT STATE. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

II HAVE A 2019 TOYOTA TACOMA 6-SPEED MANUAL TRANSMISSION. I AM EXPERIENCING A RATTLING NOISE FROM THE TRANSMISSION WHENEVER YOU ARE ROLLING FROM A LOW SPEED IN NEUTRAL. YOU WOULD BE ABLE TO HEAR THE RATTLE FROM THE TRANSMISSION INTENSIFY IF EVER YOU ARE ROLLING THROUGH A SPEED BUMP AT LOW SPEEDS IN NEUTRAL.

INITIAL NOTICE OF RECALL IN NOVEMBER 2019, BY PRESS. FAULTY FUEL PUMP CAN LEAD TO VEHICLE STALL AT HIGH SPEED. RESULANT SERIOUS INJURY OR DEATH. I HAVE INQUIRED NUMEROUS TIMES AT THE LOCAL TOYOTA DEALERSHIP IN PERSON, BY PHONE, AND EMAIL. NEVER GET THE SAME OR A RESPONSE THAT IS DEFINITIVE...I DO NOT FEEL SAFE IN THIS VEHICLE AND AFTER RESEARCHING AND FINDING A CLASS ACTION LAWSUIT ON THIS MATTER, I HAVE DECIDED TO GET RID OF THIS VEHICLE..IT HAS HAD SEVERAL RECALLS ALREADY AND NOTED SEVERAL OTHER ISSUES WITH THE TRANSMISSION SHIFTING, BODY, BRAKES AND REAR DIFFERENTIAL. TO BE BLUNT THIS VEHICLE IS SUBSTANDARD, OVER-PRICED BY TOYOTA AND HAS LED ME TO BELIEVE THAT TOYOTA DESIGN, CONSTRUCTION AND SALES ARE SHODDY AND DECEPTIVE AT BEST. *TR

ACCELERATION IS OFTEN HESITANT AND JERKY. WHEN AT A COMPLETE STOP,TURNING OR DRIVING , I WILL PUSH THE GAS TO ACCELERATE BUT THE TRUCK TAKES ABOUT 2 SECONDS TO FINALLY MOVE. THE DEALERSHIP STATED IT WAS THE TRACTION CONTROL BECAUSE I TURN TOO FAST. WHEN ASKED ABOUT WHY IT HESITATES TO ACCELERATE WHEN AT A STOP OR WHEN I'M DRIVING STRAIGHT, THEY STATED THEY DIDN'T KNOW BUT IT WASN'T AN ISSUE SINCE THEIR MECHANICALS COULDN'T REPLICATE THE PROBLEM. I DON'T FEEL CONFIDENT OR SAFE IN THIS TRUCK. *TR

DRIVING TO THE UPS BRAKE MALFUNCTION LIGHT CAME, ENGINE LIGHT CAME ON, TRACTION CONTROL OFF LIGHT ON, VEHICLE LOST POWER, ABLE TO ONLY MOVE 1 MILE AN HOUR, BRAKE MALFUNCTION LIGHT ALSO SAID BRAKE OVERRIDE, ADVISE BRING TO DEALER . LUCKILY I WAS A HUNDRED FEET AWAY FROM THE TOYOTA DEALER WHEN THIS HAPPENED LIVING IN A SMALL TOWN. TURN ON MY HAZARD LIGHTS AND DROVE INTO TOYOTA DEALERSHIP.

A COUPLE TIMES OVER THE LAST SEVERAL MONTHS, I'VE HAD PROBLEMS WITH RPMS SURGING (BETWEEN 800 & 1200) SHORTLY AFTER STARTING THE TRUCK WHEN THE VEHICLE IS COLD; BOTH WHILE IDLING IN PARK AND SHORTLY AFTER PLACING THE VEHICLE INTO D OR R. THIS HAS RESULTED IN UNINTENDED VEHICLE MOVEMENT WHEN IT STARTED SURGING AFTER THE TRUCK WAS PUT INTO DRIVE. THIS HAS HAPPENED WHEN PULLING OUT OF MY DRIVEWAY ON COLD MORNINGS OR LEAVING AN APPOINTMENT OR WORK AFTER THE TRUCK HAD SAT & COOLED. THE RPM SURGE WASN'T AN ISSUE WHILE IT WAS SIMPLY IDLING. HOWEVER, IT HAS OCCASIONALLY STARTED SURGING AFTER I PLACED THE VEHICLE INTO DRIVE. I PLACED THE VEHICLE INTO DRIVE, LET OFF THE GAS BUT HAD NOT YET (OR JUST STARTING TO) PRESSED ON THE GAS PEDAL. THE SURGING WAS POWERFUL ENOUGH TO CAUSE THE VEHICLE TO LURCH FORWARD SIGNIFICANTLY WHICH IS POTENTIALLY VERY DANGEROUS. IN ONE INSTANCE I HAD DRIVEN MAYBE 100 YARDS AND PULLED UP TO A STOP. AS I WAS JUST LETTING OFF THE BRAKE TO ENTER TRAFFIC AND NOT YET PRESSED ON THE GAS PEDAL IT STARTED SURGING AND JERKED FORWARD. I HAD TO SLAM ON THE BRAKES TO PREVENT HITTING OTHER VEHICLES. THIS LASTED FOR A MINUTE OR SO AND FORCED ME TO STAY ON THE BRAKE AND BLOCK TRAFFIC UNTIL THE SURGING STOPPED. THIS PROBLEM HAS OCCURRED ONLY A COUPLE OF TIMES BUT IS A HUGE SAFETY RISK TO MYSELF AND OTHERS DUE TO THE UNINTENDED ACCELERATION/VEHICLE MOVEMENT WHEN THE RPM'S SURGED WHILE THE POWERTRAIN WAS ENGAGED. TOYOTA HAS ACKNOWLEDGED THE SURGING AND HAS STATED THERE IS NO REPAIR AT THIS TIME. HOWEVER, TOYOTA HAS ALSO TRIED TO TELL ME THAT IT IS OPERATING AS 'NORMAL'. I HAVE TAKEN THE TRUCK TO THE SHOP SEVERAL TIMES AND THEY HAVE STATED THAT THEY HAVE SEEN THE SURGING BUT BECAUSE THEY HAVE NOT EXPERIENCED THE SURGING WHEN THE POWERTRAIN IS ENGAGED (IT HAPPENS ONLY OCCASIONALLY) THE VEHICLE IS OPERATING NORMALLY. THIS IS NOT NORMAL OR SAFE.

I TOOK MY 2019 TACOMA SR5 TO HEADQUATER TOYOTA MIAMI TODAY. I TOLD THEM THAT MY TRUCK VIBRATE WHEN BRAKING BETWEEN 25 TO 15 MPH. THEY INSPECTED MY TRUCK AND TOLD ME THEY FELT THE VIBRATION SO THEY CALLED THE CORPORATE AND THE MECHANIC WAS TOLD TO TEST DRIVE A SIMILAR TRUCK. THE MECHANIC TOLD ME THAT IT DOES THE SAME THING AND TO WAIT FOR A MAYBE RECALL. NEXT WEEK I'M TAKING MY TRUCK TO ANOTHER DEALER.

PURCHASED MY VEHICLE ON 10/19/19. SHORTLY THEREAFTER, I BEGAN EXPERIENCING THE FOLLOWING: IN THE DRIVE MODE, THE VEHICLE DOES NOT DOWN-SHIFT PROPERLY (A LAG) TO LOWER GEARS WHEN SLOWING DOWN FROM HIGHER SPEEDS(50-60 MPH) TO LOWER SPEEDS (30-40 MPH). IT STAYS IN 5TH OR 6TH GEAR TOO LONG, CAUSING THE TRUCK/TRANSMISSION TO "LUG" DOWN WITH SOME ENGINE "MISSING" BEFORE IT FINALLY DOWNSHIFTS AUTOMATICALLY. I HAVE TO DRIVE IN THE SPORT MODE AND MANUALLY SHIFT GEARS REGULARLY TO CIRCUMVENT THIS PROBLEM. THE TRANSMISSION SHIFT POINTS ARE NOT SET CORRECTLY, AND/OR THE TRANSMISSION TORQUE CONVERTER STAYS ENGAGED/LOCKED IN TOO LONG AT HIGHER GEARS WHEN SLOWING DOWN TO LOWER SPEEDS. THIS WILL EVENTUALLY LEAD TO TRANSMISSION BEARING FAILURES AND SAFETY PROBLEMS IF THE TRANSMISSION-ENGINE STARTS TO STALL/CUT OUT. TOYOTA CORPORATE HAS BEEN NON-RESPONSIVE TO MY COMPLAINT SUBMITTED.

2019 TACOMA SPORT, TRANSMISSION JUDDER, VIBRATE ON SLOWING DOWN AND LIGHT ACCELERATION ON STEP INCLINE ON TOWN OR HIGHWAY TOYOTA DEALER, TOYOTA OF OLYMPIA IN WASHINGTON SAYS IT'S NORMAL THAT WORKS AS DESIGNED. THIS CAN'T BE NORMAL GETTING WORSE THE MORE I DRIVE ONLY 3300 MILES PLS HELP WITH THIS PROBLEM MORE PEOPLE ARE COMPLAINING ABOUT THIS ISSUE. THANK YOU

HAVING ISSUE WITH THE TRUCK 'LURCHING AND JERKING" WITH RPMS FLUCTUATIONING BETWEEN 500 AND 1000. THIS HAPPENS PRIMARILY IN REVERSE WITH YOUR FOOT ON THE BRAKE WITH STEADY PRUSSURE. I HAD AN UNCOMFORTABLE INCIDENT WITH A WOMAN IN THE SUPERMARKET PARKING LOT. SHE SAW THAT I HAD STOPPED TO LET HER PASS BEHIND ME WHEN THE TRUCK TOOK A SHORT HOP BACKWARDS. SHE WAS NOT HAPPY. SHE TOOK MY PLATE # AND SAID THAT SHE WAS GOING TO FILE A COMPLAINT WITH THE LOCAL PD . I HAVE TAKEN THE TRUCK TO THE LOCAL DEALER AND THE OLD STANDARD ANSWER, " ITS NORMAL".THE TECH THAT EVALUATED MY TRUCK VERIFIED THAT IT WAS IN FACT LURCHING.. I THINK ITS A SAFETY ISSUE AND HAVE OPENED A CLAIM WITH TOYOTA CARE. THIS IS NOT A NEW ISSUE AS THERE ARE SEVERAL WRITTEN CONCERNS IN THE TACOMA FORUMS AND ON SOCIAL MEDIA. I WOULD HATE TO SEE SOMEONE GET INJURED. I AM NOT AN AUTOMOTIVE TECHNICIAN BUT I BELIEVE THIS POSSIBLY MAY BE A SOFTWARE ISSUE BETWEEN THE THROTTLE CONTROL AND ONBOARD COMPUTER

THIS TACOMA SR5 IS BRAND NEW, ABOUT 400 MILES ON IT SO FAR. NOTICING A LOT OF HUNTING BY THE TRANSMISSION TO FIND A GEAR IT IS HAPPY WITH FOR A GIVEN SPEED AND TERRAIN. BUT THE MOST CONCERNING ISSUE IS THAT IT PULSES HARD WHEN SLOWING TO A STOP. THOUGHT IT WAS THE BRAKE ROTORS AT FIRST, BUT I PUT THE TRANSMISSION IN NEUTRAL WHILE BRAKING, AND BRAKING IN NEUTRAL WORKS VERY SMOOTHLY. SEEMS MORE LIKE THE TORQUE CONVERTER DOESN'T WANT TO DISENGAGE. ALSO NOTICE A WHISTLING SOUND FROM THE REAR WHEN ACCELERATING THRU APPROX 40MPH. WILL BE TAKING IT IN TO THE DEALER SOON TO HAVE THESE THINGS CHECKED. I LOVE THE TRUCK OTHERWISE, AND WAS PLANNING TO OWN THIS VEHICLE FOR 10+ YRS, BUT THIS IS NOT A GOOD START.
