How many hours of labor is reasonable to replace the fuse panel on my car?

What is your question?

Dealership has had my car for 7 weeks. Has misdiagnosed the issue now twice and replaced parts that didn't need to be replaced based on "these are typically the parts that cause the alarm to go off without cause." Now they say they've found a leak that caused the driver's side fuse box to short out and had to replace it.
