For the past 4-5 months my car has been emitting a squeak from the back of the car. I took it to the dealer when I had my break pads and new rotors installed and fixing my check engine light. I told them about the squeak so they took apart the suspensions and said nothing was wrong with the suspension and they said they isolated it to the left rear side above the gas tank I didn’t have them take it apart anymore because my cars out of warranty and I already spent 1,600 between the pads and check engine light. My question is to you what do you think would cause this noise?? (Makes the noise when going over speed bumps and when turning slow and when u close to door of the car.. but after you pick up speed the noise goes away…)
