Faulty Ground Wire

... so I took it to the dealership to find the problem. The dealership said I have a ground wire problem and may take several hours to find. Has anyone experienced this problem? Is there a specific place to look for loose, corroded or damaged ground wires? Does the negative battery cable need to be replaced, etc?
Thanks!
