Issues with the Dynamic Brake Support system can lead to improper braking assistance, potentially causing safety concerns during emergency braking situations.

The K20C8 engine is equipped with a turbocharger, and turbo failure can lead to power loss, increased exhaust emissions, and potential engine damage.

Direct fuel injection systems can suffer from clogged or malfunctioning injectors, leading to poor engine performance, misfires, and reduced fuel efficiency.

Over time, the timing chain can stretch or wear out, resulting in poor engine timing, decreased performance, and potential engine damage if it fails.

Direct injection engines are prone to oil dilution, where fuel mixes with engine oil, reducing its lubricating properties and potentially leading to increased engine wear.

Direct injection can lead to carbon buildup on intake valves, which can cause reduced airflow, poor engine performance, and potential misfires.

Inadequate cooling or coolant leaks can result in the engine overheating, which can cause severe engine damage if not addressed promptly.

Modern engines rely on various sensors (e.g., oxygen sensors, MAF sensors) for optimal performance. Sensor failures can lead to incorrect air-fuel mixture, poor performance, and increased emissions.

Turbocharged engines, like the K20C8, can experience turbo lag, which is the delay between pressing the accelerator and the turbocharger providing boost, affecting acceleration and driving experience.

Problems with the EGR system can lead to increased emissions and decreased engine performance due to improper recirculation of exhaust gases.

The 2JZ engine is known to develop oil leaks over time, especially around the valve cover gasket and front main seal due to aging seals and gaskets.

If the Supra is equipped with the turbocharged version of the 2JZ (2JZ-GTE), common problems include turbocharger wear and failure, which can result in reduced engine performance and increased oil consumption.

Although the 2JZ engine is robust, head gasket failure can occur, especially if the engine has been modified or subjected to high levels of boost pressure.

The timing belt on the 2JZ engine should be replaced at regular intervals (usually every 60,000 to 100,000 miles). Failure to do so can result in timing belt failure, leading to potential engine damage.

Issues such as radiator leaks, failing water pumps, and clogged coolant passages can result in overheating, which can cause severe engine damage if not addressed promptly.

The ignition coils on the 2JZ engine can fail over time, leading to misfires, rough idling, and poor fuel economy.

Over time, fuel injectors can become clogged or dirty, leading to poor engine performance, reduced power, and increased fuel consumption.

Various engine sensors such as the oxygen sensor, mass air flow sensor, and crankshaft position sensor can fail over time, resulting in poor engine performance and triggering the check engine light.
