2019 Toyota Tacoma engine problems

“Engine failure can be catastrophic on I-70. Engine hesitation. Check engine light came on. Code read P11ED - Cylinder 2 Air Fuel Ratio Imbalance (Port). Shop states the cylinder valve is worn. Mileage 190,000 Note - this was "repaired" by Toyota in July 2025. In 2025, P11ED code was read. Cylinder 2 was running rich. Fuel injector was replaced. This made it worse. Caused P219D code. Truck was sent to machine shop to repair cylinder heads, spark plugs were replaced. Mileage 150,000”

“The contact owns a 2019 Toyota Tacoma. The contact stated that while the vehicle was parked, the vehicle shuddered, stalled, and there was an abnormal sound coming from the vehicle. The contact turned off and restarted the vehicle, and the vehicle returned to normal operation. The failure occurred on several occasions. The check engine and the active traction control warning lights were illuminated, with several other unknown warning lights illuminated. The vehicle was taken to a dealer to be diagnosed; however, the dealer stated that the cause of the failure was unknown. The vehicle was not repaired. The vehicle was taken back to the residence, and the contact used a diagnostic tool to retrieve DTC: P0087 (Fuel Rail/System Pressure was too Low). The vehicle was not repaired. The vehicle was taken back to the dealer, where it was determined that the octane fuel or spark plugs might need to be replaced. The vehicle was not repaired. The contact researched and was made aware of an unknown recall; however, the VIN was not under recall. The manufacturer was not notified of the failure. The failure mileage was approximately 40,000.”

“The contact owns a 2019 Toyota Tacoma. The contact stated that while driving at an undisclosed speed, there was an abnormal clattering sound coming from the engine, with a misfire coming from the engine. The check engine warning light was illuminated. The vehicle was restarted; however, the failure reoccurred. The vehicle was taken to several mechanics, where it was diagnosed and determined that the fuel injector in cylinder #3 had failed and needed to be replaced. The vehicle was not repaired. The vehicle was then taken to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 89,000.”

“The engine in my 2019 Toyota Tacoma TRD Off Road suffered internal damage that appears linked to Toyota’s low-pressure fuel pump recall (issued 10/28/2020, repaired 581 days later on 6/10/2022). While out on personal lease, the truck was driven over 16,000 miles with the defective pump, which can cause lean running conditions and elevated combustion temperatures. The result was metallic contamination and a damaged wrist pin in cylinder #6, requiring full engine replacement. All failed components remain available for inspection upon request. The fuel pump defect and resulting internal engine damage continues to place my safety and others’ at risk by creating potential for loss of power, engine stall, or total failure while driving. The problem was confirmed by two separate Toyota dealerships, both of which diagnosed the need for engine replacement. The vehicle has been inspected by multiple Toyota service centers and the Toyota Brand Engagement Center, which opened and later denied my case. No warning lights or messages appeared prior to the ticking noise that first appeared around 62,000 miles. In fact, no warning lights have ever illuminated on the dash.…”

“My check engine light came on when I was traveling in Oregon. I didn't notice any major changes in my vehicle's performance. Drove it all the way back to Colorado without issues. It went off and came back on several times. I replaced the cabin air filter, engine air filter and put fuel injector cleaner in the vehicle. Finally I took it in to the Toyota dealership to get an oil change and then the check engine light came back on. I paid for them to do a diagnostic test and they stated they were almost certain it was the 2nd fuel injector running rich. Brought it back a week later for the repair. Fyi...I was still getting 20 mpg in fuel and I wasn't noticing anything major in performance. They replaced the fuel injector and then the check engine light came back on with a different code. They are now running "another" more expensive diagnostic test and I still don't have my truck. They are saying it could be the 2nd cylinder or the engine and claiming it has 150,000 miles so I should expect these issues (and conveniently my warranty has run out).”

“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.”
