Warning Signs You Should Never Ignore ✅ Unusual Engine Noises – Knocking, tapping, or grinding sounds from the engine often signal serious internal problems. ✅ Dashboard Warning Lights – Ignoring lights like the check engine or oil indicator could lead to breakdowns. ✅ Burning Smell – A sharp odour could indicate overheating, oil leaks, or even electrical short circuits. ✅ Fluid Leaks Under the Car – Any puddles under your vehicle—oil, coolant, or transmission fluid—are red flags.
