V-shaped engines like the 2UR-GSE can experience misfires due to ignition coil or spark plug issues, especially if not maintained properly.

V8 engines can experience higher oil consumption, which may lead to lower engine performance if not monitored regularly.

The PORT+DIRECT fuel injection system can lead to carbon buildup on intake valves, affecting engine efficiency and power.

Over time, the timing chain in V8 engines can stretch or wear out, potentially leading to timing issues and engine performance problems.

Powerful engines with high horsepower, like the 472 hp engine, may experience overheating if the cooling system is not functioning optimally.

Direct injection systems can sometimes lead to clogged fuel injectors, resulting in reduced engine performance and efficiency.

Common problems can include false activation, where the system engages unnecessarily, or failure to activate when required, potentially due to sensor malfunction or software issues.

High horsepower engines are more prone to overheating, which can lead to engine knock, pre-ignition, or even complete engine failure if not properly managed.

V-shaped engines can suffer from balance and vibration issues, which may lead to increased wear on engine components and potential failure of engine mounts.

Known issues with this engine model include carbon buildup on intake valves, which can affect performance and fuel economy, and oil consumption problems.

Engines with more cylinders can be more complex and expensive to repair, and they may also have higher fuel consumption.

Specific to the 2020 Lexus RC F, common problems include transmission issues, such as rough shifting or delayed engagement, and electronic system malfunctions, including infotainment and driver-assist features.

Dual injection systems can suffer from carbon buildup on the intake valves and fuel injectors, leading to reduced performance and potential misfires.

Problems with the DBS system can include failure to activate during emergency braking, false activation, or software glitches that may require an update or reconfiguration.

A V-shaped engine with 6 cylinders, like the V35A-FTS, can sometimes produce excessive noise due to worn-out components, improper lubrication, or exhaust system issues.

V-shaped engines are prone to oil leaks, which can stem from valve cover gaskets, oil pan gaskets, or other seals and gaskets wearing out over time.

The V35A-FTS engine (often turbocharged) may experience issues like turbo lag, reduced power output, or turbo failure due to wear and tear or insufficient maintenance.

Complex V-shaped engines can suffer from cooling system issues such as radiator leaks, thermostat failures, or water pump malfunctions, leading to overheating.

Engines with both port and direct fuel injection systems might encounter fuel delivery problems, injector clogging, or high-pressure fuel pump failures.

Problems such as misfires, poor starting, or rough idling can occur due to faulty spark plugs, ignition coils, or wiring issues.

Timing components in V-shaped engines can wear out, leading to stretched chains or belts, which can cause poor engine performance or even engine damage.

Issues with the catalytic converter, EGR valve, or oxygen sensors can lead to increased emissions and potential failure to meet regulatory standards.

Modern engines like the V35A-FTS rely heavily on electronic sensors and control units, which can fail or produce erroneous readings, affecting overall engine performance.
