Hey there everyone. I bought a 2017 GT about a year ago. Love the car however it seems to have developed a new noise that’s driving me crazy. Two months ago I noticed a popping/ knocking noise coming from the rear passenger side. It wasn’t all the time, but enough to pique my attention. I hear it mostly at low speeds, going over small bumps and dips in the driveway. When I had it serviced at Mazda the tech checked it out and said he couldn’t find anything wrong with the suspension, but heard what sounded like a noise in the trunk. Fast forward a month and the noise is worse. Brought it back and drove around with the tech who heard it and looked over the car before deciding it was a loose spare tire. Well it definitely isn’t. Noise is now near constant at low speeds on both sides. The tech had pushed on the plastic protective housing when looking the car over and it did sound similar, but I honestly can’t tell if that’s the issue. Plus I haven’t found a post from anyone complaining about it. Is it normal? Am I just nitpicking and being paranoid?
