General Signs of Engine Trouble that Should Be Brought to the Mechanic’s Attention ASAP

Your vehicle’s engine is the heart of its performance, and when it starts showing signs of distress, quick action can make the difference between a simple repair and a costly rebuild. Ignoring early warning signs can lead to severe damage and even complete engine failure. By paying attention to unusual sounds, performance changes, or dashboard alerts, you can catch problems before they escalate. At Murphy Family Auto Repair, we provide expert engine repair in the greater Mesa, AZ area. Here are five common signs of engine trouble that should be addressed by a mechanic as soon as possible.
Check Engine Light Is On
One of the clearest warnings of engine trouble is the check engine light illuminating on your dashboard. While it can signal a range of issues—from a loose gas cap to serious engine malfunction—it should never be ignored. The mechanic can use diagnostic tools to pinpoint the exact cause and help you resolve it before it becomes a bigger problem.
Unusual Noises from Under the Hood
Knocking, tapping, or grinding sounds coming from your engine are never normal. These noises often indicate worn-out components. A knocking sound in particular can be a sign of poor lubrication or misfiring, which can cause internal damage if left unchecked. Any unfamiliar noise from the engine bay warrants a professional inspection to prevent further harm.
Decreased Power and Performance
If you notice your vehicle struggling to accelerate, experiencing rough idling, or losing power while driving, it’s a sign of trouble. Common causes include clogged fuel injectors and ignition system problems. Even small changes in performance can indicate developing issues that will only worsen over time, so it’s best to have a mechanic evaluate the cause immediately.
Discolored/Excessive Smoke from the Exhaust
The color of your exhaust smoke can reveal a lot about your engine’s condition. Blue smoke suggests oil is burning, white smoke can indicate coolant leakage from a blown head gasket, and black smoke often points to an overly rich fuel mixture. Any of these conditions can lead to worsening engine issues if not corrected promptly.
Fluid Leaks/ Burning Smells
Puddles under your vehicle or the smell of burning oil or coolant are strong indications of a leak. Engine oil and coolant are vital for lubrication and temperature regulation, and low levels can quickly lead to overheating or internal wear. A mechanic can identify the source of the leak and repair it before it causes permanent damage.
