What owners say about the power train

Verbatim from NHTSA complaints, newest first
“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.”

“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.”

“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.”

“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.”
