GMC Envoy squeaky noise after starting, quiets as vehicle warms up on GMC Envoy

Some GMC Envoy owners report experiencing a squeaky noise after starting their vehicle, which diminishes as it warms up. This noise may be linked to a loose belt or issues within the steering system. Additionally, worn brake pads, tire problems, or insufficient lubrication in the suspension could contribute to the squeaking. Moisture in the morning is also noted as a factor that can lead to these noises while driving. If the noise is more pronounced during startup, it may indicate potential issues such as piston slaps, sticky lifters, worn accessories, main bearing wear, or drain back. Some owners have also reported rattling sounds at startup that disappear shortly after. It is crucial for owners to have a professional mechanic inspect their vehicle to accurately diagnose and resolve the underlying cause of the squeaky noise.
