| Jul 2026 | SERVICE BRAKES | Brake master cylinder is leaking in the interior of truck on driver side floor mat. Oil is come from brake master cylinder seal. | Crash: No Fire: No | Unknown |
| Jun 2026 | ELECTRICAL SYSTEM | 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) | Crash: No Fire: No | Unknown |
| Jun 2026 | ELECTRICAL SYSTEM | Digital instrument panel speedometer screen has gone blank. No longer displays speed. This occurred while driving the vehicle. | Crash: No Fire: No | Unknown |
| Jun 2026 | LANE DEPARTURE,BACK OVER PREVENTION | About a month ago the Blind spot monitoring system failed, dealer said $2500.00 to repair, about 10 days ago, backup sonar parking system failed, dealer cost to repair $2200.00 | Crash: No Fire: No | Unknown |
| May 2026 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Apr 2026 | FUEL/PROPULSION SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Mar 2026 | SERVICE BRAKES | when I push the brake pedal, it goes to the floor. I have had the brakes and master cylinder replaced. after about one month the brakes started failing again.

| Feb 2025 | POWER TRAIN | 1. What component or system failed or malfunctioned, and is it available for inspection upon request? The "coolant bypass hose/joint" (Part #: 16356-31051) located at the rear of the engine, connecting the two heads, failed. This part is made of plastic and is known to be a weak point in the 3.5L V6 (2GR-FKS) engine. The failed component is still in the vehicle and can be inspected upon request. 2. How was your safety or the safety of others put at risk? A coolant leak from this component can lead to engine overheating, which could cause sudden engine failure while driving, increasing the risk of an accident. Since the leak is not easily visible under the hood, a driver may not notice the issue until significant overheating occurs, potentially leaving them stranded in unsafe conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was confirmed by the dealership after an inspection. They identified the coolant bypass hose/joint as the source of the leak. Many users on the forum TacomaWorld have also experienced the same issue with their vehicles. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by the dealership, but it has not been inspected by Toyota directly, the police, or an insurance representative. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or dashboard messages indicating a problem. The only symptom was a small puddle of coolant on the ground a week after purchasing the vehicle. Upon further inspection, a trail of coolant was observed running down onto the passenger side of the transmission bell housing. Would've costed me 1,000 dollars if didn't have warranty. | Crash: No Fire: No | Unknown |
| Dec 2024 | ENGINE | 2021 Toyota Tacoma OR coolant bypass joint leaks at only 47800 miles. The cost of repair is $1490.36 | Crash: No Fire: No | Unknown |
| Oct 2024 | SERVICE BRAKES | When stopping vehicle (for instance, at a stop light), vehicle would stop normally when pressing the brakes, but after a few seconds, the vehicle would start forward again. The brake pedal would give way and press down further, stopping briefly before starting forward again - so I had to use the emergency brake or else vehicle would move into oncoming traffic. I consulted a mechanic, and it was diagnosed as a bad brake master cylinder. This vehicle has only 51,000 miles on it, being a 2021 model. The brake pads themselves were checked and they are fine. I replaced the master cylinder and it fixed the issue, but I wouldn't expect this unsafe condition to already be happening to this vehicle, especially this early in life. Toyota must have defective brake master cylinders. | Crash: No Fire: No | Unknown |
