Why Does My Car Screech When Turning On?

Have you noticed that your car screeches when turning it on? We understand how unsettling that sound can be—it’s loud, sudden, and often signals an underlying issue with your vehicle. At Sid Dillon Buick of Lincoln, we’re here to help you understand what’s going on under the hood and get your vehicle running smoothly again.

What Causes My Car To Screech When Turning It On?

Several common issues can lead to that high-pitched screech when you start your car:

• Serpentine Belt Issues: A worn, loose, or glazed serpentine belt may slip on pulleys, especially when cold, causing a squealing or screeching noise.
• Power Steering Problems: Low power steering fluid, a worn-out pump, or leaks in the system can result in noise and reduced steering performance.
• Brake Components: While more common when braking, worn brake pads or rusty rotors can sometimes emit noise upon startup.
• Alternator or Accessory Drive Issues: A failing alternator bearing or misaligned drive components may produce a screeching noise when your engine first starts.

Car Screeches When Turning It On: When To Be Concerned

While a brief screech can sometimes be harmless, consistent or worsening noises may indicate a bigger problem. If your car screeches when turning it on regularly, watch for these warning signs:

• Screeching accompanied by loss of power steering
• Dimming headlights or electrical issues
• Engine overheating
• A burning rubber or oil smell
• Malfunctioning air conditioning or alternator

These symptoms may indicate that a critical component is failing. Continuing to drive with a worn serpentine belt or faulty accessory can lead to a breakdown or further engine damage.

If your vehicle is displaying any of these signs, bring it to Sid Dillon Buick of Lincoln for a complete inspection. Our certified service technicians will determine why your car screeches when turning on and provide the repairs you need to stay safe on Omaha roads.
