It could be your brakes. I had this problem. Find a road where it does it, drive over without your brakes pressed, drive over it again with you brakes pressed slightly and see if it makes a difference. Vauxhall changed the caliper carriers for an updated version and it fixed the problem. Basically the pads were rattling in the caliper over rough roads but with the brake pressed it stopped. Hope this helps
