Selected complaints filed with NHTSA by 2019 Toyota Tacoma owners, lightly cleaned up (personal details are redacted by NHTSA).
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. …
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
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 differential skid plate was manufactured in a way that one of the brackets make contact with the fuel tank of the truck. It rubs and compromises the integrity of the tank. Possibly leading to a puncture and leak. I brought it to the attention of the manufacturer, and they have stated that they received several complaints from customers and redesigned the skid plate to prevent this. However they refused to replace mine and others, they also have taken NO steps to notify owners of this safety hazard.
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.
About 70,000 miles, bearings on the idler pulley and tensioner on serpentine belt failed. These have been replaced. About 75,000 miles, the rack and pinion began leaking from one end. I'm watching power steering fluid levels and expect to replace the rack and pinion soon. Note: I'm being told the design of this vehicle requires that the engine be partially pulled to replace the rack and pinion.
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
I purchased and drove a brand new 2019 Toyota Tacoma trd off road 4x4 6'bed off the lot, with only ten miles on it. I was driving on the interstate back to my hometown and was broken down on the side of the road at 236 miles. While driving on the interstate, the RPM odometer gauge suddenly began to jump rapidly while the vehicle simultaneously lost power and speed and the whole vehicle lurched forward abruptly a few times. I pulled over immediately. I turned off the vehicle. Turned it back on, and it lurched forward and was clearly not drivable so I turned it back off. At no point did any check engine light or warning signals go off on the vehicle either while driving or after having pulled over. It was three hours before roadside assistance got a tow truck to arrive. …
For no reason at all my 2019 Toyota Tacoma sr5 stalled and displayed a "high transmission temp warning". This occurred when picking up my child from school. The truck would not shift and the breaks did not function I had to use ebrake to not hit other vehicles, and was stuck in the middle of the school parking lot with my two young children in az heat. I waited awhile after turning the truck off and shifting to park then turned vehicle back on and it then functioned as normal. I then took the Tacoma to avondale Toyota, for a diagnosis and repair. So far they have made no repairs as they said they could not replicate the problem and are on day two of having the vehicle testing it to see if it will have issue again. This could be a very dangerous situation if the situation was to occur on a highway or interstate or in the middle of 115 degree weather. …
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. …
