Owner reports

Selected complaints filed with NHTSA by 2018 Toyota Tacoma owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2018 Toyota Tacoma. The contact stated that while driving at an undisclosed speed, the vehicle made a rattling sound. Upon inspection, the contact noticed that the fuel tank cover had detached due to the well nuts being corroded. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 56,000.

On June 26, 2025, around 9:30 AM, I was driving my Tacoma on the highway at approximately 70 mph when the truck suddenly lost power. I was in the center lane and nearly got hit as I tried to exit the highway. After exiting, the engine warning light came on, and the truck eventually stalled. I was able to restart it with limited power and drove it to a nearby shop. The shop's diagnosis revealed several warning codes, and the fuel pressure was found to be only 14 psi. They recommended replacing the low-pressure fuel pump. After researching known fuel pump issues, I had the truck towed to a local Toyota dealership. The dealership confirmed the codes but couldn't replicate the low-pressure reading after driving for about 30 miles. Because of this, they stated that it didn't qualify for the extended recall offered by Toyota. …

The fuel pump as stopped working the vehicle will not start and the 4x4 is showing that it is not working. The vehicle is available for inspection. Thankfully this happened while the vehicle was sitting over night but we had driven it the evening before it just stopped running. the Fuel system could have failed while we were driving anywhere. It has not been inspected by anyone else. it is sitting in our driveway and my husband has done a lot of trouble shooting as to what could be wrong and all arrows point to the fuel pump. there have been no check engine light or nothing this came out of nowhere.

The vehicle every time I fuel either does start afterwards or it would start and drive for about 3-6 minutes then it will stall. The very first time it happened was on the highway which I didn't know why my car had stall but now that it has done it right at the fuel pump and also more often than not. I tried using other gas stations just to rule out bad fue but it has been like this for the past 6 month. I have taken it to Toyota MCDONOUGH in Georgia and they could not give a diagnostic because the check engine light does not stays on and they said they can't replicate the problem.

The contact owns a 2018 Toyota Tacoma. The contact received notification of NHTSA campaign number: 20V012000 (Fuel system, gasoline) however, the part to do the recall repair was unavailable. The contact called the local dealer who confirmed that the part was not yet available. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

When accelerating on highway check engine light started flashing and engine running rough. Pulled over and stopped vehicle turned off ignition. Restarted vehicle and light was out no longer running rough. Toyota dealer checked computer, cylinder #2 misfired 47 times & cylinder #3 misfired 3 times. They said they could not find what had created this problem and still charged me for engine diagnostics.

2018 Toyota Tacoma SR 4WD Double Cab, 3.5L V6 (2GR-FKS). At about 87,000 miles the check engine light came on with code P11EC, Cylinder 1 Air-Fuel Ratio Imbalance (Port). Cylinder 1 failed compression. Leakdown and coolant tests had passed earlier; borescope did not show heavy scoring. The Toyota dealer said replacing the direct injectors would fix compression (quote about $4,499). After the dealer injector repair, cylinder 1 was still 124 psi (spec about 142-180 psi), so it did not fix compression. The dealer then quoted $11,778 for a short block (+$500 incidentals) and $14,238 for an engine assembly that was not new (about 45,000 miles on the replacement discussed); adding injectors again put the short-block path at about $16,278. I was steered toward buying a new truck and had the injector work reversed because it did not fix what they said it would. …

The manufacturer has exceeded a reasonable amount of time for the recall remedy (see below). My truck has been sitting in my driveway (per the instruction of autonation fort myers) since March 10, 2020. I was provided a rental through autonation in fort myers, fl (at their expense) until the remedy was available to consumers. I was advised that the remedy would be available at the end of March, beginning of April. Then I was advised that it wouldn't be until the end of September, middle of October. Meanwhile, my truck is sitting in my driveway accumulating additional issues because I was instructed not to drive it. I was also advised that multiple vehicle types have already been remedied and that Tacoma's have not. …

The vehicle stalls intermittently. It is as if the traction control system is cutting throttle input for 1-2 seconds. This occurs in heavy stop and go traffic. Specifically, if accelerating to 10-15 miles per hour, then stopping, then attempting to accelerate again, the truck suffers an engine stall. The traction control dashboard indicator does not light up during this occurrence; however, the engine performs very similar to instances when the traction control does operate. The stall also occurs when slowing down to turn into driveways, etc. There is no required intervention to correct this issue; it simply lasts 1-2 seconds, then operates as normal. The vehicle was taken to two different dealerships (both Toyota). Neither was able to replicate the issue. I was told the vehicle did not have any error codes and there was nothing that required service. …
