We have a 2015 pathfinder with about 45k miles. At around 60 to 70 mph, we get a random clunk under the vehicle. Kind of sounds like metal hitting a fan and getting spit out, but only lasts a second. It almost feels like something small is hitting under our feet. Theres no change in rpms, or performance when it happens. Still has a smooth ride as well. But its really annoying! Happens every now and then, but seems to be happening more often. Worry that its something serious. Anyone else have this issue or any ideas what it could be??
Thanks in advance for any advice!
