Power Train Problems of Toyota Tacoma - part 2

Transmission is failing, fluid was black and burnt at 35k miles (dealer did not provide a large enough sample to allow for testing the fluid because I didn't specify the amount I needed), and vehicle is not throwing a cel or mil so therefore Toyota says that there is no defect. Fluid change did improve the functioning, but it did not correct the problem. Transmission failures are a known problem on numerous Toyota vehicles using an a series transmission. My vehicle has done this and progressively worsened since it had roughly 500 miles on it. Dealership originally refused to document my complaints in their system and Toyota customer care's assistance has been minimal at best. My vehicle suffers from numerous of the same complaints that are listed under the 2024 model Tacoma. Before servicing the transmission fluid the vehicle would occasionally have an extremely hard shift around 55mph that would result in the truck spinning tires on the interstate which shouldn't even be possible. I actually managed to capture a short video of the dash as it was doing this once and even sent it to Toyota but they said if they can't replicate it then it doesn't count. I think there needs to be an investigation into Toyota's transmission issues as well as someone should investigate their programming for mil/cel activation parameters as their vehicles are alerting the driver's to a problem until there is a complete and total failure which could leave the driver in an unnecessary and dangerous situation that could possibly be avoided if the driver was informed when the "fail-safe" features activate instead of when they're unable to compensate. I am unable to load the video through this computer; however, I can upload the video from my phone upon request.

Transmission slips and shifts roughly, intermittently. No codes have shown up when scanned at the dealer.

The transmission slams gears, looses power when shifting on acceleration, and goes into a neutral while in parking lots at low speeds. The truck also while stopped will shutter and feel like it just got hit.

While driving the vehicle there is a groaning sound coming from the front end of the Tacoma from the front differential. There is a TSB from Toyota, but they only cover it under warranty and are not treating it as a recall. TSB # 0026-15. I think this is something that is causing wear to the front differential and could cause further damage/could lead to a crash if something was to lock up. The sound is consistent from 15-55 mph no matter the driving.

Vehicle was set in tow/haul mode. Tow/haul mode provides higher acceleration by changing the operation of transmission. Vehicle was towing 2500lb cargo trailer on interstate. Driver stopped at rest area and turned off engine and left vehicle. Driver returned to vehicle 5 minutes later. Driver started engine and proceeded to leave the rest area. Driver was on highway entrance ramp. Entrance ramp merges with right lanr driver attempted to accelerate to enter highway in such a way that there would be safe distance between end of trailer and car on highway approaching end of trailer. Vehicle would not accelerate as quickly as it was accelerating for the past 2 hours. Driver was surprised and distracted. Margin of safety between rear end of trailer and car on highway was greatly reduced. Some time after the incident driver realized that car forgot it was in tow haul mode whenever engine is turned off. There is no warning that mode changed. This means that car does not behave as reasonably expected after an ignition cycle.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? the "coolant bypass hose/joint" (part #: 16356-31051) located at the rear of the engine, connecting the two heads, failed. This part is made of plastic and is known to be a weak point in the 3. 5l v6 (2gr-fks) engine. The failed component is still in the vehicle and can be inspected upon request. 2. How was your safety or the safety of others put at risk? a coolant leak from this component can lead to engine overheating, which could cause sudden engine failure while driving, increasing the risk of an accident. Since the leak is not easily visible under the hood, a driver may not notice the issue until significant overheating occurs, potentially leaving them stranded in unsafe conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, the issue was confirmed by the dealership after an inspection. They identified the coolant bypass hose/joint as the source of the leak. Many users on the forum Tacomaworld have also experienced the same issue with their vehicles. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? the vehicle was inspected by the dealership, but it has not been inspected by Toyota directly, the police, or an insurance representative. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? there were no warning lamps or dashboard messages indicating a problem. The only symptom was a small puddle of coolant on the ground a week after purchasing the vehicle. Upon further inspection, a trail of coolant was observed running down onto the passenger side of the transmission bell housing. Would've costed me 1,000 dollars if didn't have warranty.

The contact owns a 2024 Toyota Tacoma. The contact stated that while shifting into gear, the vehicle jumped and continued to move. There were no warning lights illuminated. The contact received notification of NHTSA campaign number: 25v058000 (service brakes, hydraulic). The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 18,000.

The morning my transmission failed. . . I started the truck and put it in r, at which point the entire truck shuddered for several seconds. At this point many, many warning messages appeared on the instrument cluster screen as well as the infotainment screen - and the truck would not move in reverse. After moving the shifter into p and back to r, the truck backed out of the driveway. When the truck was shifted to d - nothing happened. The truck was shifted back to r and then back to d at which point the truck moved forward but would not shift out of 1st gear. Placed truck back in p and then back to d two more times and truck would move forward but not shift out of 1st gear. Turned truck off and on approximately 3 times and it began to shift gears when driving. I drove the truck to the closest Toyota dealership where the warning codes were checked, and I was told that my transmission was bad and needed to be replaced. I was told that it would need a new torque converter assy, new automatic transmission assy, and a new hybrid module assy. Total cost for parts would be $27,504. 29. . . . Covered by warranty. My truck was purchased brand new in virginia, mn on [xxx], and the failure occurred on [xxx] with less than 800 miles on the vehicle. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The transmion for this vehicles has been runing roughft and hard shiftin. This vehicles has les than 5,000. The croblemas been incresing consering and becamong more ovius with the higher usage of this unit. This hapens especialy when first engagin in first gear from parking. Also when shifting from first to secong gear. This is a automatic transmision.

My 2024 Tacoma sr5 was stuttering and felt like the wheels are locking up when I accelerate I have to go very slow because when going anything over 30 mph feels very unsafe and is hard to control and handle it shut off a lot of my systems like crash detection and 2-3 other ones are cut off on my dash it threw a check engine light so going to take it in to Toyota tomorrow to get it looked at I don’t know if I even want this truck anymore.

The vehicle has a vibration at speeds in excess of 40mph. The dealer has confirmed that the wheels are balanced and that the truck is in alignment. They have duplicated the issue on my truck and have driven an identical model and experienced the same inherent vibration. There are also mentions of this vibration in Tacoma forums online specific to the trd off-road variant.

Stopping at a stop light, after coming to a complete stop, vehicle will want to slowly creep forward and you need to press a little harder on the brake pedal. If you don't pay attention, you will creep into the vehicle in front of you. I am in the transmission TSB range.

Throwout bearing premature failure. Saftey was put at risk with harsh shifting and potential transmission failure while merging into traffic due to not going into gear. Was brought to a shop to install a new tob and had to replace my pressure plate as well due to wear. Tob is now doing something similar causing noises due to wear on the shaft it rides on. This is a very very common problem and should be addressed as a failure point especially for what little milage is on the truck.

My new 2024 Toyota Tacoma trd pro with 2440 miles experienced a transmission failure as I was driving up a mountain highway. I lost most propulsion of the vehicle with no advanced notice. I barely was able to make it to a portion of the road with a shoulder. There was heavy traffic due to the thanksgiving holiday traffic. The error on the vehicle indicated hybrid system failure. In the vehicle information I was able to access additional errors, “a malfunctions in the intelligent clearance sonar system has been detected”, and “a malfunction in the drive start control system has been detected”. The vehicle was towed to a local Toyota dealer and the have diagnose that the transmission and a computer need to be replaced. The problem arose suddenly without warning and with out any prior issues.

I bought the truck at 6 pm on [xxx] in pennsylvania and drove straight home in brooklyn, when trying to find a parking spot the truck started to act weird(10pm after 190 miles). The rpm was going really high with no power to the wheels and abruptly it seems to find gear and jumped off really fast a couple of times. I was driving in a residential area at low speed and was able to pull over to the curb. I could have hit a pedestrian, another car or lost control pretty badly if I was in a highway. After the initial incident all the lights came off (engine malfunction, brakes malfunction, collision system malfunction and others). The truck was towed and after a long wait, today the 5th of December, it was diagnosed as a transmission problem, Toyota is going order a new transmission and the broken one will be sent to Toyota for further inspection. They want to replace my truck and it seems they are not willing to cancel the deal. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have had below issue at 57000 miles on my Tacoma. I was told by the dealer that I am not under the warranty, and coporate that there is no recall for my truck by search VIN, but its clear im experiencing the same issues as below and seeing other videos on youtube experiencing the same issue, so its clear this truck was built with the same defects. The plano, texas-based manufacturer sent a safety recall report to the national highway traffic safety administration (NHTSA) stating they will recall 6,046 2018 Toyota camry, 2018 Toyota highlander, 2017 Toyota sienna, 2017 Toyota Tacoma, and 2017 Lexus rx350 vehicles built between oct. 2 and Nov. 3, 2017. Toyota stated in the report the affected vehicles contain brake booster vacuum pump assemblies with improperly machined oil galleys. The vacuum pump is supplied oil from the engine to seal and lubricate the pump vane’s movement. The defect can cause oil to not properly circulate through the system, eventually breaking the pump vane and causing potentially dangerous braking assist loss.

Since day one vibration and pulsing 30-45mph. Dealer confirmed vibration and said it common with my vehicle and nothing can be done. Returned to dealer same issue confirmed by tech and service manager and they charged $75 for tire balance at 5,000 miles. Returned next day and drove another identical model and 3 lesser versions of Tacoma’s. They claim they have no fix and suggested I trade it in for a tundra and take a $10,000 deductions from my sticker price. Now when I stop slowly theres a thump and surge in the drive train like s load shifted in the bed. And intermittently when going from a dead stop the engine rev’s nothing happens for a second and it clunks into gear and shifts harshly. Again claim there’s nothing they can do.

When I was driving my new truck the transmission failed. It would not change gears forward or reverse. The rmp started ramping up in the red. Check engine light on drive start control malfunction. Advanced ultrasonic detecting and ranging system. The led screen was going hoops asking for code and updating while driving day before transmission went. Called dealer. Had the car towed. Later that day was told bye dealer the transmission needs to be replaced. Did research to find out Toyota new theses transmission are faulty and have not recalled. If I where on highway or similar roads I drive daily I would have been hurt. This problem will cause a accident. I am aware the NHTSA has been informed, reached out to Toyota and Toyota has not responded nor have they started a safety recall. My fear is they are waiting for someone to get hurt or killed. My dealer also informed me another customer with a Tacoma has been waiting since may 2024 for a transmission.

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.

When starting from a stop on at a stop light on a steep hill, the truck did not accelerate and started rolling backward almost hitting multiple vehicles. I was able to get it stopped but had to wait to get help to move it off the road before being able to get it moving forward again.

?it makes a lot of vibration uphill 25-40mph. ?it feels like hunting gear when itñs shifting to the second gear. ?it got stock in second gear in the middle of the traffic and there was risk because cars where behind me yelling me.

When at stop light transmission would not fully engage and started thru intersection was only going approx 20 mph. Engine went to 3500 rpm before it shifted again. After I arrived at my destination started truck back up again and received warning on dash and check engine light came on. Had check engine and drive control system warning messages. Still had same problem with it at stop lights and transmission seemed to not be shifting properly. Was able to get it to dealer and next day received call from them stating that I needed new transmission.

I purchased the 2024 Tacoma trd pro on 9/5/24. On 9/20/24 the transmission failed with just over 1,000 miles driven on the truck. I was stopped at a traffic light when the problem occurred. Multiple sensor alarms were triggered including hybrid system malfunction. I attempted to accelerate when the light changed, but it was very sluggish and felt like it was trying to take off from a high gear. I was less than 1 mile from a Toyota dealership when the malfunction occurred and was able to get the truck to the dealership. After a week of troubleshooting, the dealership informed me that the transmission was stuck in 6th gear due to a solenoid failure and they would need to replace the transmission. The transmission is currently on backorder with an estimated delivery between 10/14 and 10/26. Based on the current estimate, by the time I get the truck back, I will have made two months of lease payments while only having the vehicle in my possession for 2 weeks.

Automatic transmission fault that locked the vehicle in 2nd gear. The vehicle was taken to a local dealership for service, and Toyota refused to replace the transmission and torque converter as per their own repair procedure, claiming it must be replicated in order to authorize the repair. This is an already known fault by Toyota, yet their response was that a dangerous condition has to be duplicated even though vehicle diagnostic codes show that two transmission solenoids were stuck, and even though I provided them photos of the multiple warnings on the driver’s dash from when it occurred. Other vehicles with the same condition have been repaired without question. Vehicle had 1,574 miles on it and 1,579 once I arrived at the dealer.

I purchased the vehicle new and noticed right away that the transmisson would clunk right away when I put it into gear[ it's an automatic]. I asked the dealership about it and they said it was normal and no issues. Now I'm [xxx] and have owned many cars so. . . . Anyway, over the years I've asked several times and they say no issue. Now, just this morning, my wife found an article about the issue and Toyota is finally admitting there is an issue. What can I do? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

New 2024 Tacoma sport. Approx. 3800 miles. While driving automatic transmission revved hi, like it was in neutral. Lost power, went into limp mode. Multiple warnings on dash. Had truck towed to dealer. Next day they said transmission needed replaced. Metal filings found inside transmission. Not sure how long it would be to repair. The dealership was very kind and sorry this happened. I told them it's not there fault, it's Toyota.

Purchased truck with 127 miles, at 327 miles noticed it wasn't shifting. Took truck back to Toyota and they stated there were metal shavings in the transmission and it needed to be replaced. They also stated they have no idea when they would be able to get a transmission.

The automatic will get stuck in a high gear, making it impossible to accelerate. I was almost hit trying to merge into traffic with the transmission failing. Going from reverse to drive, the vehicle will "buck", lurching forward. When at a red light, if the auto start/stop function kicks in, the car will also lurch into gear moving forward.

What component or system failed or malfunctioned, and is it available for inspection upon request? transmission, and yes its available for inspection. When I put the truck into drive from park, and even reverse, the truck would jerk. (I have videos) when accelerating around 13-14mph, I could feel the transmission "gear searching" with rough shifting. When decelerating around 15-17mph, the transmission would down shift too early, producing the feeling of engine breaking, and again rough shifting. When I needed to really go, I experienced "transmission lag" where the engine would be working, reving up, the feeling of engaging the clutch (coasting feeling), then after a moment the gear would catch and the truck would finally take off. I took the truck to a dealership to have it checked out, but the technicians said they couldn't reproduce this issue. I called corporate and they sent me to another dealership. This dealership said the same thing, but went the next step and pulled some transmission fluid and found metal shavings. They had the truck for almost 3 weeks and replaced the transmission and torque converter. When I went to pick up the truck I put the truck into drive and felt the jerk I experienced before. I put it into reverse then drive, and again the whole truck jerks. I asked to speak to a manager and he said he can have the foreman look at it the next day. I made him get in the truck with me and showed him the truck jerking when placed into drive. Next day, foreman said there was nothing wrong and performed the same as a new truck on the lot. I spoke to a higher manager and he recommended I bring the truck in for the regional field technician. The field technician reviewed the vehicle and determined there was nothing wrong and it was performing the same as 3 new trucks on the lot.

While driving on the highway a hybrid system malfunction occurred, which caused the vehicle to be thrown into 2nd gear. Took the vehicle to dealership and they determined that the transmission had failed. The vehicle was only 1 week only and only had 822 miles on it.

Transmission failure.

Drivers side front cv axle boot not clamped from factory. This caused grease to be thrown throughout wheel well including onto brakes. No warning lamps or indicators. Dealer confirmed issue but has no eta for parts to repair.

I was driving on the freeway going 68-70 mph when I had a sudden loss of power. Vehicle could not maintain speeds and was sluggish while making it over to the side of the road. Vehicle was towed to dealership, which could not initially find anything. Next day after test driving vehicle, it was confirmed that the transmission is broken.

The contact owns a 2024 Toyota Tacoma. The contact stated while driving at an undisclosed speed, the vehicle stalled. No warning light was illuminated. The contact restarted the vehicle and drove to the residence. The vehicle was towed to the dealer, where it was determined that the transmission was stuck in sixth gear, and the transmission needed to be replaced; however, the parts were on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 2,300.

Eight speed transmission exhibited difficulty in downshifting to lower gears. Loud rumbling sound could be hard inside of truck cabin. Also, upon my inspection, found transmission fluid leaking on the garage floor. All of this occurred at less than 400 total miles on the vehicle. Vehicle was inspected by the local dealer Toyota service department and determined to be a defective transmission that must be replaced. It is possible that the transmission could have seized up while driving, causing the vehicle to be uncontrollable. No warning lamps or messages . . . Only the loud audible sound coming from the transmission. To date, it is unknown as to the cause of failure. At my request, Toyota has assigned a case number (#240809001043) and is investigating the failure.
