4 Common Signs of Engine Trouble that Demand Prompt Attention

Roy’s Quality Car Care • 24 June 2025

Your vehicle's engine is the powerhouse that keeps things running, and when something goes wrong, it can lead to serious problems if not addressed quickly. Recognizing the early warning signs of engine trouble can help you avoid more extensive repairs. At Roy’s Quality Car Care, we provide expert engine repair in the greater Hagerstown, MD area. Here are four common signs of an engine problem.


Unusual Noises

Strange sounds coming from under the hood are one of the most noticeable indications of engine trouble. Knocking noises can indicate bearing issues. Squealing sounds may be related to a loose or damaged belt. Any unfamiliar noise should be taken seriously, as it can signal problems that, if left unchecked, may lead to an engine breakdown.


Warning Lights on the Dashboard

Modern vehicles are equipped with sensors that monitor engine performance. When something is wrong, the check engine light or other warning indicators will illuminate on the dashboard. While some issues may be minor, others could be signs of serious engine damage. It's important not to ignore these warnings. A professional diagnostic scan can help identify the source of the problem before it becomes worse.


Discolored/Excessive Smoke from the Exhaust

Discolored and/or excessive smoke coming from the exhaust pipe is never a good sign. Blue smoke commonly indicates that the engine is burning oil, white smoke may suggest coolant is leaking into the combustion chamber, and black smoke points to excessive fuel consumption. Each of these symptoms can be a sign of a different but serious issue. Continued driving without addressing the problem could lead to major engine damage.


Rough Idling or Stalling

If your engine is idling roughly or stalling at stops, something is definitely wrong. These symptoms could be caused by dirty fuel injectors, faulty spark plugs, or more serious internal problems. A healthy engine should run smoothly and consistently, so any irregular behavior is worth getting checked out.
