The Multi-Information Display (MID) on the instrument cluster (combination meter) has failed completely. The display shows full-width horizontal RGB scan lines across the entire screen with no readable information. The analog gauges (speedometer and tachometer) remain functional but all digital display information is unavailable including speed, warnings, fuel economy data, and safety system status indicators. This failure occurred suddenly with no prior warning. Vehicle has approximately 50,000 miles. I am aware that Toyota issued Safety Recall 25V595 in September 2025 covering the identical combination meter failure on 2023-2025 model year Tacomas and other Toyota vehicles. The root cause identified in that recall — accelerated deterioration of the memory device inside the combination meter due to improper programming — appears to be the same failure mechanism present in my 2021 model year vehicle. I am filing this complaint to formally document that this known defect extends to 2021 model year Tacoma vehicles and to request that NHTSA investigate expanding recall 25V595 to include earlier model years. Toyota should be required to repair or replace the combination meter on affected 2021 vehicles at no cost to owners, consistent with the remedy already established for 2023-2025 vehicles. A Toyota case has been opened with the Brand Engagement Center at [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE — Filed 05/25/2026

The plastic coolant crossover valve or pipe failed at 66,000 miles and 5 years of usage. This led to the radiator cracking. After researching online, I read about thousands of Tacoma 3rd generation users with the same issue. Also, the same issue was recalled for several other models of Toyotas but not the Tacoma.

FUEL/PROPULSION SYSTEM — Filed 04/22/2026

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.

I am going to take it back to the mechanic to have them re-evaluate the brakes. No kind of official has inspected my truck. I have been having braking issues for about a year.

There are three concerns in this write up: at 117000 miles the blind spot monitoring system has fails and will cost $300 to repair. More concerning is that it was recommended I replace the Power Steering Lines at a cost of $927 and the Transmission Lines at a cost of $797 due to severe rusting and corrosion. Its recommended before they rust through and break/leak.
