Problems:
Oil leaks
Engine oil leaks can be common due to worn gaskets or seals, which can lead to insufficient lubrication and potential engine damage.
Overheating
Overheating issues may arise from a malfunctioning cooling system, such as a faulty thermostat, water pump, or radiator, which can cause engine damage.
Misfires
Engine misfires can be caused by faulty spark plugs, ignition coils, or fuel injectors, leading to poor performance and increased fuel consumption.
Timing chain/belt issues
Problems with the timing chain or belt, such as stretching or breaking, can cause serious engine damage due to improper valve timing.
Turbocharger failure
If equipped with a turbocharger, failure or issues with the turbo can lead to reduced power and increased emissions, often due to oil contamination or bearing wear.
Fuel system problems
Clogged fuel injectors or a failing fuel pump can lead to poor engine performance, stalling, and starting issues.
Sensor failures
Faulty sensors, such as the oxygen sensor, mass airflow sensor, or crankshaft position sensor, can cause poor engine performance and increased emissions.
Exhaust system issues
Problems with the exhaust system, such as a clogged catalytic converter or exhaust leaks, can affect engine performance and emissions.
Battery and electrical issues
Electrical problems, such as a weak battery or faulty alternator, can lead to starting issues and poor engine performance.
Software/firmware glitches
Modern engines with advanced electronic controls can experience software or firmware issues that affect performance and drivability.
