What causes the abnormal noise in the new Regal?

[DelBeau]

The abnormal noise in the new Regal is caused by oil leakage or bending of the shock absorber itself. Abnormal noise from parts: The car's gear shifting structure consists of the gear lever, cables, gear selection and shifting structure, shift fork, and synchronizer. The abnormal noise from these parts is relatively minor. Long-term use of transmission oil: Long-term use of transmission oil can lead to sludge formation, increasing the wear of friction plates and various components. Wear in these parts can cause faults and abnormal noises. If the sound during gear shifting is minor and comes from near the gear lever, it is a normal phenomenon caused by the gear shifting mechanism. If the gear shifting produces a clicking sound, it is due to a fault in the transmission gear impact.

Recently, my car had a similar issue. The abnormal noises in the new Regal could be caused by various reasons. Common causes include a loose suspension system, such as shock absorbers or ball joints making squeaking sounds on bumpy roads; loose interior components like door panels or dashboard clips rubbing and creating noise while driving; or loose pulley belts or fans in the engine compartment, producing a humming sound during acceleration. I recommend starting with a simple self-check: drive in a quiet area to locate the source of the noise, and lightly tap the interior to check for abnormal vibrations. If the noise persists, visit a professional repair shop immediately to avoid safety risks from suspension issues. For new cars, most cases are due to improper assembly, and timely tightening or part replacement can resolve the issue—don’t delay to prevent worsening conditions that affect driving comfort.

As a car owner, my experience is that abnormal noises in the new Regal mostly occur in the suspension or interior. Suspension issues, such as a clunking sound when going over speed bumps, may be due to improperly secured shock absorber brackets. For the interior, loose door panel clips are common, causing rattling sounds on bumpy roads. I've encountered aging belt noises in the engine compartment, resembling a hissing sound. Try locating the noise source yourself by shaking the wheels when parked to listen for abnormalities, or check for debris stuck in interior gaps. Recording the sound for the mechanic can speed up diagnosis. Addressing minor issues early saves big repair costs later—sometimes it's just adjusting screws or replacing a small part. Regular maintenance checks for abnormal noises ensure peace of mind when driving on highways.

Preventing abnormal noises in the new car is key. My methods include avoiding rough driving on bad roads to reduce component wear. Pay more attention to sound changes while driving, especially during the break-in period of a new car. If you encounter abnormal noises, stop in a safe place, tap the interior to locate the sound source, and try reinforcing loose clips. During maintenance, ask the technician to focus on the suspension and engine belt tension. Conduct a comprehensive inspection every 5,000 kilometers to prevent small issues from becoming major ones. Interior cleaning is also important—keep fewer items inside to avoid friction noise. This way, daily maintenance is easy and cost-effective.
