Misfires in V-shaped engines, like the AJ133 S/C, can be due to issues with spark plugs, ignition coils, or fuel injectors.

V8 engines, such as the one in the 2018 Range Rover Sport, can develop oil leaks from valve cover gaskets, oil pan gaskets, or other seals.

The AJ133 S/C engine might experience timing chain stretch or failure, leading to poor engine performance or even severe engine damage.

Since the AJ133 is supercharged, problems with the supercharger such as bearing wear or belt issues can adversely affect engine performance.

V8 engines can be prone to overheating due to coolant leaks, faulty water pumps, or radiator issues.

The fuel system, including pumps and filters, may fail or get clogged, affecting the engine's performance.

Modern engines rely on various sensors (e.g., oxygen sensors, mass air flow sensors) that can fail and cause drivability issues.

Issues with the exhaust system, such as catalytic converter failure or exhaust leaks, can lead to reduced performance and increased emissions.

Misfires can be caused by faulty spark plugs, ignition coils, or fuel injectors, leading to poor engine performance and increased emissions.

Common in high-performance engines like the AJ133 S/C, oil leaks can occur from gaskets, seals, or oil lines, resulting in low oil levels and potential engine damage.

V8 engines can experience timing chain wear or tensioner failures, which can lead to poor engine timing and potential catastrophic engine damage if not addressed.

The supercharged engine may face issues with the supercharger itself, such as bearing wear or belt slippage, leading to reduced performance.

High-performance engines generate a lot of heat, and failures in the cooling system, such as radiator leaks or thermostat malfunctions, can lead to overheating.

Issues with the fuel pump, fuel filter, or fuel lines can cause poor fuel delivery, leading to engine stalling or poor performance.

Problems with the exhaust system, including leaks or clogged catalytic converters, can affect engine performance and emissions.

Modern engines rely on various sensors (e.g., oxygen sensors, mass airflow sensors) to run efficiently. Failures in these sensors can lead to poor engine operation and diagnostic trouble codes.

Although not part of the engine, transmission issues can often be mistaken for engine problems, especially in vehicles with high torque outputs like the Range Rover Sport.

Complex electrical systems in modern vehicles can lead to various problems, including engine control module (ECM) failures or wiring issues, affecting engine performance.

DBS uses sensors to detect potential collisions and automatically applies the brakes. Malfunctions can lead to delayed or insufficient braking assistance.

The AJ126 engine has been known to develop coolant leaks, which can cause overheating and engine damage if not addressed.

The timing chain tensioner on the AJ126 engine can wear out, leading to timing chain rattle and potential engine misalignment.

Direct injection engines like the AJ126 can accumulate carbon deposits on intake valves, leading to reduced performance and fuel efficiency.

The 2018 Range Rover Sport with the AJ126 engine may experience supercharger whine or noise due to worn bearings or issues with the supercharger drive belt.

The AJ126 engine may develop oil leaks from valve cover gaskets or other seals, leading to oil consumption and potential engine damage.

For variants equipped with a turbocharger, there can be issues with the turbocharger failing, leading to reduced power and potential engine damage.

The 2018 Range Rover Sport is known for various electrical issues, including problems with the infotainment system, sensors, and wiring harnesses.

The air suspension system in the Range Rover Sport can fail, leading to a rough ride, uneven ride height, and expensive repairs.

The ZF 8-speed automatic transmission used in the Range Rover Sport can have problems with shifting, hesitation, and transmission fluid leaks.
