What are the causes of the abnormal noise in Song Pro?
3 Answers
The causes of the abnormal noise in Song Pro may be due to abnormal front wheels, loose chassis fasteners, or abnormal engine accessories. Confirming the existence of the fault: During a test drive with the customer on a flat road, a clear metallic "clicking" sound could be heard inside the car when slightly pressing the accelerator pedal, confirming the existence of the fault. Checking engine accessories: After lifting the vehicle with a lift, inspections of the front wheel brake discs, dust covers, all bolts and ball joints in the chassis showed no abnormalities. When checking the engine accessories, it was found that the air conditioning high-pressure pipe was loose when shaken by hand. Further inspection revealed that the bolt securing the air conditioning high-pressure pipe was loose. After tightening the bolt, the abnormal noise disappeared during the test drive.
My auto shop frequently encounters SongPro owners complaining about abnormal noises, with suspension issues being the most common. For example, a thudding sound on bumpy roads usually indicates loose front suspension arm bolts or worn shock absorbers. Interior noises are also prevalent, such as clicking sounds caused by aging dashboard clips or loose seat rails. It's recommended to start with simple checks, like tightening screws with tools. If there's a whistling noise at high speeds, it might be due to damaged door seals or air leaks from sunroof gaps. I've also encountered brake pad noises, like metallic squealing, which means the pads or discs need replacement. Don't ignore abnormal noises; prolonged neglect can affect safety. It's best to have a mechanic thoroughly inspect the chassis and interior components during regular maintenance, especially for vehicles frequently driven on rough roads, to ensure all parts are secure.
I've been driving the Song Pro for half a year and encountered chassis noises, with creaking sounds when turning. A mechanic friend said it might be loose stabilizer bar links. There's also a humming noise during acceleration, possibly due to improper installation of the turbocharger in the engine bay or belt wear causing internal gaps. The interior is quite annoying too, with the glove box door or door panels rattling loudly on bumpy roads. I tried adding some vibration-damping adhesive myself, and it became much quieter. There are also brake issues—screeching sounds during light braking at low speeds indicate rusted brake discs or hardened pads. When the AC is on, system noises might suggest unstable compressor mounting. It's advisable to start troubleshooting from the most noticeable noises, record the scenarios when they occur, and then have them checked by after-sales service. Don't just guess and fix based on sounds alone.
