I have a 2016 Latitude and am at 36,000 miles. I have a very faint yet still very annoying high-pitched squeaking seeming to come from my passenger seat whenever the car goes over little bumps. I thought it was the chair and first and tried adjusting and moving and jiggling it to stop, but that doesn't seem to be the case. It's difficult for me to pinpoint where the sound is coming from because it only sounds when I'm in motion and it only occurs when going over small cracks or bumps. I've tried googling and it seems like it may be the transmission or suspension, but nothing about my specific issue. Any ideas or suggestions? I really would like to understand the problem and try to avoid a long diagnostic session if I do need to go in for a repair service.
