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.

The V-shaped engine configuration can cause heat accumulation, leading to potential overheating issues.

High-performance engines like the 2UR-GSE in the Lexus RC F can consume engine oil at a higher rate, requiring frequent checks and top-ups.

The complex engine configuration with 8 cylinders can sometimes lead to misfiring, especially if spark plugs or ignition coils are faulty.

Direct injection engines are prone to carbon build-up on the intake valves, which can affect performance over time.

With advanced engine management systems, sensor failures can lead to check engine lights and performance issues.

High-performance engines can experience timing chain wear, leading to potential engine damage if not addressed.

The high precision required for fuel injection in performance engines can lead to injector clogging or failure.

The powerful engine can put extra stress on the exhaust system, leading to potential wear and leaks.

Given the high power output, the transmission can sometimes struggle to handle the torque, leading to potential shifting issues.

Although standard, the DBS system can experience sensor or software malfunctions, affecting braking performance.
