Toyota 4Runner screeching noise from inside the car upon ignition on Toyota 4Runner

Some Toyota 4Runner owners report experiencing a screeching noise upon ignition, which may indicate issues such as a loose or worn serpentine belt located under the hood. Others have noted that slipping of the belt can lead to squeaking noises that diminish as the belt warms up from spinning. Additionally, if the noise is louder and seems to originate from the steering column, it may suggest a different issue compared to a quieter noise coming from under the gas and brake pedals. It is crucial for owners to seek a professional mechanic's inspection to accurately diagnose and resolve the specific cause of the screeching noise.
