The GDI TAU engine in the 2014 Hyundai Equus is known for higher-than-average oil consumption, which can lead to frequent oil top-ups and potential engine damage if not monitored.

Direct injection engines like the GDI TAU are prone to carbon deposits on intake valves, which can cause rough idling, reduced performance, and increased emissions.

Some owners have reported issues with the timing chain tensioner, which can lead to a noisy engine and potential engine damage if the chain skips or breaks.

Fuel injectors in GDI engines can become clogged or fail, leading to poor engine performance, misfires, and reduced fuel efficiency.

The 2014 Hyundai Equus may experience leaks in the cooling system, which can cause the engine to overheat and lead to serious engine damage if not addressed promptly.

Various sensors, such as the oxygen sensor and mass airflow sensor, can fail, leading to poor engine performance and reduced fuel efficiency.

Due to the high performance of the GDI TAU engine, spark plugs may wear out more quickly, necessitating more frequent replacements to maintain optimal engine performance.

Due to the high performance of the GDI TAU engine, spark plugs may wear out more quickly, necessitating more frequent replacements to maintain optimal engine performance.

Higher oil consumption can occur due to worn piston rings or valve seals, leading to frequent oil top-ups.

This can be caused by using lower octane fuel than recommended, carbon buildup, or issues with the timing.

Dirty or clogged fuel injectors can lead to poor fuel economy and misfires.

Timing chain or belt wear can cause engine performance issues and, if not addressed, severe engine damage.

Problems with the radiator, water pump, or thermostat can cause the engine to overheat.

Misfires can be caused by faulty spark plugs, ignition coils, or fuel delivery issues.

Malfunctioning sensors such as the MAF, O2, or knock sensor can lead to various engine performance problems.

Problems with the turbocharger can lead to reduced power and efficiency.

Dynamic Brake Support (DBS) may fail to activate correctly, reducing its ability to assist in emergency braking situations.

The GDI TAU engine may experience misfires due to issues with fuel injection, ignition coils, or spark plugs.

This engine model may have higher-than-normal oil consumption, requiring frequent oil level checks and top-ups.

Direct injection engines like the GDI TAU are prone to carbon build-up on intake valves, which can affect performance and fuel efficiency.

Various sensor failures or engine control module (ECM) issues can trigger the check engine light, requiring diagnostic scans to pinpoint the exact problem.

Problems with the radiator, water pump, or thermostat can lead to overheating, especially in high-performance engines like the GDI TAU.

Although not directly related to the engine, issues with the transmission can affect overall vehicle performance, especially in a high-torque engine.

Leaks or blockages in the exhaust system can lead to reduced engine efficiency and increased emissions.

Contaminants in the fuel system can cause clogging of injectors and fuel filters, affecting engine performance.

Electrical problems can interfere with the engine's electronic control systems, leading to starting issues or erratic performance.
