Vehicles using NG engine list:

Engine NG commonly faces issues like oil leaks, ignition coil failures, and sensor malfunctions. For diagnosis, regularly check for oil seepage around valve covers and gaskets, and monitor engine performance for misfires or rough idling indicating ignition problems. Prevention includes timely oil changes using recommended grades and inspecting spark plugs and coils every 30,000 km. Solutions involve replacing worn gaskets to stop leaks, swapping faulty ignition coils, and cleaning or replacing sensors such as the MAF or oxygen sensor to maintain optimal fuel-air mixture. Keeping the cooling system in good condition also prevents overheating, which can damage engine components.
