What's the cause of Nissan Sylphy noise?

[DallasRose]

Nissan Sylphy noise may be caused by loose buffer springs in the mid-section of the chassis exhaust pipe or tire issues. Below are detailed explanations of the possible causes: Loose exhaust pipe springs: If the noise is mainly from the chassis, it could be due to loose buffer springs in the mid-section of the exhaust pipe. This is a common issue with certain Nissan models and is generally difficult to resolve. Abnormal noises might also stem from loose chassis screws, such as those in the front engine underguard or other components in the engine compartment. These can be inspected by lifting the vehicle. Tire issues: If the noise is primarily from the tires, it could be related to tire material, tire pressure, tread design, or abnormal tread wear. Both overinflation and underinflation can produce different types of noise, so adjusting to the proper tire pressure can help reduce noise. To address material-related tire issues, the only solution is to replace the tires.
