2021 Toyota Tacoma Fuel System Problems

After I purchased my 2021 Toyota Tacoma TRD Sport with 4 miles on it and at 1,332 miles on 11/26/21, the Check Engine light with Traction Control Off light came on while I was driving. I immediately pulled over and on the truck media screen it read this: "A malfunction in the electronic control of the engine, throttle or automatic transmission has been detected. Contact your Toyota dealer and have your vehicle inspected." The truck was rough idling and had no acceleration. I had the truck towed to dealership where it was purchased and upon diagnostic, it was determined that #3-cylinder injector was reading "Open Circuit" with code P020313. Being under warranty the dealership repaired the bad injector. No further issues until 4/22/26. On 4/22/26 with mileage at 48,361, I started my truck in my driveway and immediately recognized that the truck was rough idling and the Check Engine Light along with the Traction Control Light Off being on. The exact same message displayed on the screen as above, "A malfunction in the electronic control of the engine, throttle or automatic transmission has been detected. Contact your Toyota dealer and have your vehicle inspected.". The truck was towed back to the same dealership and upon diagnostic the same issue of #3-cylinder injector "open circuit" with code P020313 was revealed. It was recommended to replace the bad #3-cylinder injector and also recommended to go ahead and replace all of the spark plugs. The total repair bill we be ~$2600 when I go to pick it up in 3 days. This is not just a coincidence that the exact same #3-cylinder injector has gone bad at 1,332 miles and then again at 48,361 miles. Seems to be a connection between the injector going bad and the issues that they have had with the High Pressure Fuel Pumps. Toyota needs to acknowledge this problem.

The contact stated that her husband detected a fuel odor coming from the vehicle after the failure. The driver was able to restart the vehicle and drove the vehicle to the dealer. While at the dealer the vehicle was test driven and the failure was acknowledged. The vehicle was then diagnosed with a defective fuel pump. The vehicle was repaired but remained with the dealer. The manufacturer was not notified of the failure. The failure mileage was approximately 75,000.

The contact owns a 2021 Toyota Tacoma. The contact stated that upon starting the vehicle, the fuel pump was very noisy while having a routine oil change at an independent mechanic. There was an abnormal clacking sound detected. There were no warning lights illuminated. The contact stated that the failure was related to NHTSA Campaign Number: 20V682000 (Fuel System, Gasoline).

High-pressure and low pressure fuel pumps. Yes it is available for inspection. The truck cannot maintain posted, speed limit, causing a potential rear end collision. I reported the problem they replaced the high-pressure fuel pump for free and then said the low pressure fuel pump needs replaced the truck only has 40,000 miles. I think there’s a defect in this part that could cause lots of accidents. Check engine light is flashing and the ATC light comes on, the engine starts to sputter and cannot maintain speed.

When filling truck at any gas pump or station the pump will not shut off before shoots out from filling port. Gasoline will shoot onto my hand and clothing if at full flow at pump. I have adapted to slow pump to trickle at 11-12 gallons or near full. It will still eject gasoline but less amount and less velocity. Has been evaluated at dealer but they noted two other Tacomas do same so noted not a problem. This is my first vehicle that has ever done this. If I was a smoker this would be huge fire risk if gasoline gets on my clothing. This is not normal.
