I have the 2019 Honda Insight lx model with 5,500 miles. Like a month ago I had noticed a very faint high pitch squeak sound when pulling up in the driveway. It was coming from the rear end when tires in the back hit the bump in the driveway. I took it to the dealership and then had one of the service techs test drive it with me. We were able to duplicate that same sound. Car stayed at the dealership for a day and got it back. No squeaks for like 2 days and then it started to make the squeaking noise when going into bumps. Dropped it off again at the dealership and they haven’t been able to find the problem. They can clearly hear it but they have determined it’s inside the trunk. Has anyone had an issue related to this? At this point We’re not sure what is causing this noise I kinda gave up.
