DBS may fail to engage or may engage unexpectedly, causing erratic braking behavior.

Misfire in one or more cylinders can result in rough idling, loss of power, and increased emissions.

Problems with the turbocharger can lead to loss of power, excessive smoke, and poor fuel economy.

Engine oil leaks can occur from gaskets, seals, or other engine components, leading to oil consumption and potential engine damage.

A failing timing chain or belt can cause severe engine damage if it breaks or slips, leading to costly repairs.

Issues with the radiator, water pump, or thermostat can cause the engine to overheat, potentially leading to engine damage.

Problems with the fuel pump, injectors, or fuel filter can cause poor engine performance and starting difficulties.

Issues with sensors such as the mass air flow (MAF) sensor, oxygen sensor, or throttle position sensor can lead to poor engine performance and increased emissions.

If the transmission is not functioning correctly, it can cause shifting issues, unusual noises, and potential damage to the engine.

Problems with the vehicle's electrical system, such as a faulty alternator or battery, can lead to engine starting problems and other performance issues.

DBS system might fail to provide additional braking force during emergency situations, potentially due to sensor issues or software glitches.

The T-GDI Theta II engine can experience overheating issues, possibly due to coolant leaks, faulty thermostats, or radiator problems.

The turbocharger in the T-GDI Theta II engine may fail, leading to reduced power and performance. This can be caused by oil contamination, bearing wear, or excessive heat.

Direct injection engines like the T-GDI Theta II are prone to carbon buildup on the intake valves, which can result in poor engine performance and reduced fuel efficiency.

The T-GDI Theta II engine can have high oil consumption, which may be due to worn piston rings or valve seals.

The T-GDI Theta II engine may experience knocking or pinging noises, often due to using lower octane fuel than recommended or issues with the ignition timing.

Fuel injectors in the T-GDI Theta II engine can become clogged or fail, leading to poor engine performance and misfires.

The T-GDI Theta II engine may have problems with the timing chain, such as stretching or failing, which can cause severe engine damage if not addressed promptly.

The Hyundai Elantra N can experience various electrical problems, including issues with the engine control unit (ECU), sensors, or wiring that can affect engine performance.

The engine may experience misfires due to faulty spark plugs, ignition coils, or fuel delivery issues.

The EGR valve can become clogged or fail, leading to increased emissions and reduced engine efficiency.

Although not directly related to the engine, transmission problems can affect overall vehicle performance. The Elantra N might experience issues such as rough shifting or transmission slipping.
