Q: Car has chirping sound on rough roads

asked by on

My car has around 112k miles and is in excellent condition except for the following problem. Behind the driver’s seat in the rear-inside area, there is a chirping sound. This happens when I'm driving on a rough-surfaced road. I was told by the dealer that this is normal due to the stress in the rigid frame of the car. I don't agree with him. The sound is coming from the area of the carpets that cover the left quarter windows. I decided to disassemble the area, but everything looked normal. I even added insulation, but the chirping still exists. My car has never been in any accident and I keep it well maintained. What is your diagnosis and how can I fix it?

Hello there,

A few different things can cause this type of noise. The most common would be interior pieces rubbing against each other, a wind noise, or one of the window seals.

I’d suggest having the car looked at by a qualified technician, such as one from YourMechanic, who will be able to diagnose this noise and determine if a fault is present.
