The Dynamic Brake Support system may fail to activate or function improperly, leading to reduced braking performance during emergency situations.

This could be due to issues with the ignition system, fuel delivery, or internal engine components, leading to rough idling, poor acceleration, and reduced fuel efficiency.

If equipped with a turbocharger, it may encounter issues such as boost leaks, worn bearings, or damaged impellers, which can affect engine performance.

Problems such as clogged fuel injectors, fuel pump failures, or contaminated fuel can lead to poor engine performance and increased emissions.

Issues with the radiator, water pump, or thermostat can cause the engine to overheat, leading to potential engine damage.

Leaks or blockages in the exhaust system can lead to increased emissions, reduced engine performance, and potential damage to the catalytic converter.

Wear or failure of the timing chain or belt can lead to engine misalignment, resulting in poor performance or engine damage.

Faulty sensors, such as the oxygen sensor, mass airflow sensor, or throttle position sensor, can lead to incorrect engine management and performance issues.

Leaks from the engine seals, gaskets, or oil pan can lead to low oil levels, resulting in engine wear or damage.

Issues with the valves, lifters, or camshaft can lead to poor engine performance, misfires, and potential engine damage.

Dynamic Brake Support (DBS) systems can occasionally fail due to sensor issues or software glitches, leading to reduced braking efficiency.

The 2GR-FKS engine may sometimes consume more oil than expected, requiring frequent oil level checks and top-offs.

The PORT+DIRECT fuel injection system can lead to carbon buildup on intake valves over time, potentially causing rough idling and reduced performance.

The timing chain tensioner in the 2GR-FKS engine can sometimes fail, causing a rattling noise and potentially leading to more severe engine damage if not addressed.

The V-shaped configuration can contribute to cooling system leaks, particularly around the water pump area.

Some models experience premature fuel pump failure, leading to stalling or difficulty starting the engine.

The 2021 Toyota Tacoma has been reported to have occasional transmission shifting issues, which can result in a rough or delayed gear change.

There can be a noticeable lag in throttle response, which may affect acceleration and overall driving experience.

Fuel injectors can become clogged or fail, causing misfires, rough idling, and decreased fuel efficiency.

In some cases, the exhaust manifold can develop cracks, leading to exhaust leaks and potentially affecting emissions performance.
