The causes of abnormal noise inside the Buick Excelle when driving are loud engine noise and bearing burn-out causing abnormal sounds. Details are as follows: Loud engine noise: This is usually due to air leaks in the engine's intake pipes, improperly installed air filters, or detached vacuum hoses. These issues can cause such noise while driving. A thorough inspection is needed to ensure the intake pipes are properly sealed, restoring normal operation. Timely maintenance ensures stable, comfortable, and safe driving. Bearing burn-out causing abnormal sounds: Drive the car up to 80KM, then shift to neutral and coast while listening carefully. If the noise becomes clearer, it can be concluded that one of the four wheel bearings has a problem. If the noise disappears when coasting in neutral, it is usually due to a faulty bearing in the engine. Common engine bearing burn-outs involve the water pump, generator, or tensioner pulley.
I recently experienced interior noises while driving my Excelle, most likely due to suspension system issues like worn shock absorbers or bushing wear, causing squeaking sounds when driving over bumps. It could also be loose interior trim pieces, such as door panel plastics or center console covers rubbing, producing rattling noises on rough roads. I also noticed the seat rails aren't very stable, especially when the rear seats shake. As parts age, gaps increase, creating noise from wind or vibrations. For safety, first inspect the suspension, test drive on different road sections to locate the sound source. If unresolved, take it to a shop for repair - just a few hundred yuan will fix it. Regular maintenance can prevent this, just replacing some parts will do.
