... 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!

there are several in every car.

the most typical issues are with the battery cables and the engine block grounds but it could be any ..
you need a FSM for your car to chase them all. spend the $40 it will be worth it.
