Dynamic Brake Support (DBS) systems can sometimes malfunction, leading to reduced braking efficiency or unexpected braking behavior.

V-shaped engine configurations like the AJ126 can produce significant noise, especially if there are issues with engine mounts or exhaust systems.

Jaguar engines, including the AJ126, are occasionally prone to oil leaks, which can result in low oil levels and potential engine damage.

V6 engines can suffer from cooling system problems, including radiator leaks or water pump failures, leading to overheating.

Some Jaguar engines have experienced issues with timing chains, which can result in poor engine performance or, in severe cases, engine failure.

Injector issues can lead to poor fuel economy, rough idling, or difficulty starting the engine.

Modern vehicles like the 2020 Land Rover Discovery often have complex electronic systems that can fail or produce error codes, affecting various functionalities.

If equipped with a turbocharger, it may experience wear and tear, leading to reduced power and efficiency.

Automatic transmissions in Land Rover vehicles can sometimes suffer from shifting problems or fluid leaks.

The Land Rover Discovery is a heavy vehicle and may experience premature wear on suspension components like bushings, shocks, and struts.

Issues with the DBS system can lead to inconsistent or unreliable braking assistance, particularly in emergency situations.

The supercharger, being an additional component in the engine, can experience wear and tear, leading to reduced performance, unusual noises, or potential failure.

The AJ126 engine has been known to have issues with the timing chain tensioner, which can lead to engine knocking noises and, if not addressed, severe engine damage.

The V-shaped engine configuration can sometimes be prone to coolant leaks, which can cause overheating and potential engine damage if not properly maintained.

This engine model can experience problems with the fuel injectors, leading to misfires, rough idling, and reduced fuel efficiency.

Modern Land Rover vehicles, including the 2018 Discovery, often experience issues with their electronic control systems, which can cause various engine performance issues and warning lights.

If the engine variant includes a turbocharger, it may suffer from issues such as oil leaks, reduced boost pressure, or complete failure, affecting overall engine performance.

The AJ126 engine in some instances may suffer from oil dilution, where fuel mixes with the engine oil, reducing its lubricating properties and leading to increased engine wear.

Problems with the crankshaft sensor can lead to difficulties in starting the engine, engine stalling, or erratic engine behavior.

Direct injection engines, like the AJ126, can experience carbon buildup on intake valves, leading to reduced performance, rough idling, and possible engine misfires.
