A front-end clunk over bumps on your G90 II is usually worn suspension hardware, not a sensor fault.
Here’s what to inspect first and when to stop driving.
A clunk from the front of your Genesis G90 II over bumps and potholes is one of those noises that sounds worse than it often is—but it still deserves attention. On this large luxury sedan, the front suspension carries a lot of weight and uses sophisticated air/adaptive damping hardware, so a worn bushing or loose mount can transmit a surprisingly sharp knock into the cabin. The good news is that the usual culprits are mechanical and findable with a careful lift inspection.
