Dynamic Brake Support (DBS) systems, while helpful, can sometimes malfunction or fail to activate properly, resulting in reduced braking efficiency.

With a naturally aspirated engine, there can be performance issues such as loss of power or inconsistent acceleration, especially if the engine is not properly maintained.

The varying engine brake horsepower (200-205 hp) might lead to inconsistent engine braking performance, particularly noticeable during manual and automatic transmission shifts.

A 4-cylinder engine, if not well-maintained, can experience cylinder misfires, leading to rough idling, reduced power, and increased fuel consumption.

As a 2018 model, general wear and tear could affect various engine components, requiring regular maintenance to ensure optimal performance.

Naturally aspirated engines generally have lower power output compared to turbocharged engines, which might not meet performance expectations for some drivers.

The Dynamic Brake Support system may experience issues such as sensor malfunctions, software glitches, or calibration errors. This can result in the system not engaging properly during emergency braking situations.

The engine brake may not provide the expected deceleration force, which can be due to issues like exhaust valve problems, vacuum leaks, or control module faults.

Common in 4-cylinder engines, misfires can be caused by problems such as faulty spark plugs, ignition coils, fuel injectors, or issues with the engine control unit (ECU).

Naturally aspirated engines can develop oil leaks over time, which may originate from the valve cover gasket, oil pan gasket, or other engine seals.

The engine may overheat due to cooling system failures, such as a malfunctioning thermostat, radiator problems, or a failing water pump.

The CEL can be triggered by a range of issues, from minor sensor faults to more serious engine component failures, requiring diagnostic scans to identify the root cause.

Problems with the exhaust system, such as catalytic converter failure, exhaust manifold leaks, or muffler issues, can affect engine performance and emissions.

If the vehicle experiences a noticeable decrease in fuel efficiency, it could be due to clogged air filters, dirty fuel injectors, or issues with the fuel delivery system.

Over time, the timing chain or belt may wear out or stretch, leading to poor engine performance, misfires, or even engine damage if not addressed promptly.

Although not directly related to the engine, the transmission can affect engine performance, especially if there are issues with the automatic transmission (AT) or manual transmission (MT) clutch and gear systems.

The Dynamic Brake Support system may fail to activate correctly, leading to reduced braking performance or failure to assist during emergency braking situations.

A misfire in one or more of the cylinders can occur due to issues such as spark plug failure, ignition coil problems, or fuel injector faults.

Overheating can arise from a malfunctioning cooling system, such as a faulty thermostat, radiator issues, or low coolant levels.

Oil leaks may occur from gaskets, seals, or the oil pan, leading to decreased engine lubrication and potential damage.

Problems with the timing chain or belt can cause the engine to run poorly, misfire, or even suffer severe damage if the timing is off.

Issues within the fuel system, such as a clogged fuel filter, failing fuel pump, or dirty fuel injectors, can lead to poor engine performance.

Leaks or blockages in the exhaust system can cause performance issues, increased emissions, or unusual noises.

Leaks in the intake manifold can lead to engine performance problems and reduced efficiency due to improper air-fuel mixture.

Malfunctions in the Engine Control Unit (ECU) or associated sensors can lead to various engine performance issues, including poor fuel economy and power loss.

Naturally aspirated engines generally have lower power output compared to turbocharged engines, which might not meet performance expectations for some drivers.

A common issue in engines with 4 cylinders, which can be caused by a variety of factors such as faulty spark plugs, ignition coils, or fuel injectors.

Some Toyota 86 models have reported higher than usual oil consumption, which can be due to worn piston rings or valve seals.

Over time, the timing chain can stretch or the tensioner can fail, leading to poor engine performance or even engine damage.

Fuel pump issues can lead to poor fuel delivery, causing the engine to run rough or stall.

Some 2017 Toyota 86 models were subject to a recall for faulty valve springs, which could cause the engine to stall or lose power.

Due to the compact engine bay and high-performance nature, overheating can occur if the cooling system is not maintained properly.

A knocking sound from the engine could be related to issues with the connecting rod bearings or piston slap, especially in high-performance engines.
