For most drivers, sounds are usually the first sign of an issue. Squeals, squeaks, rattling, and knocking noises are just a few of the sounds you may hear that indicate a mechanical problem. If you've noticed a strange noise from your car, here are some tips on figuring out the issue.

Squeaky Brakes

If you hear squeaking sounds from the brakes, this is a good indication that you need to bring your car to a technician. Often, brakes emit a high pitched squeaking or squealing sound when the brake pads or rotors are wearing out. After examining the brakes, a technician can determine the appropriate servicing or repair for the noise.

Engine Rattling

Have you noticed a rattling noise from your engine? This sound typically indicates that the engine is igniting prematurely, also known as pre-detonating. This issue is often caused by an overheated engine, ignition timing malfunctions, or incorrect fuel octane ratings. When any of these happen, incorrect air and fuel mixtures in the engine cylinder lead to premature ignition. While you may not notice any major issues when you first hear this rattling noise, you should be aware that the problem can lead to further damage over time, including damage to connecting rods, valves, and pistons.

Engine Clicking

If you hear a clicking sound from your vehicle engine, this is probably related to oil levels. When you go too long between oil changes, the oil levels may have become too low in the engine. You can check the level yourself using a dipstick, or have one of our expert technicians check for you. If an oil change doesn't stop the clicking sound, there may be an upper valvetrain issue. Some common valvetrain issues include excessive lash in the valves, worn out parts, and damaged parts.

Knocking From Under the Hood

Hearing a knocking sound from under the hood should prompt immediate attention. This sound can be an indication of several major problems, including damage to or malfunction of valves, pistons, connecting rods, or other engine parts.

Engine Squealing

A squealing engine may be an indication of several different issues. Engines in old cars tend to make a squealing sound due to a worn-out accessory belt. The accessory belt is connected to the function of several other systems, including air conditioning, alternator, and power steering. For newer cars, this squealing sound may indicate a damaged or malfunctioning serpentine belt.

If you've noticed any of these sounds from your car lately, bring the vehicle to our Toyota dealership in Grapevine for assistance.
