Re: Customer service?
If that's a Subaru Legacy you're referring to there, the trick I've found for headlamp replacement is to go in through the wheel well.
Which should not, repeat not not not, be necessary, mind you, but there it is.
I bought a pack of those little plastic pressure clips to reattach the wheel well cover, rather than trying to re-use the existing ones, and I can replace the headlamps in about 5 minutes these days. Seriously, though, you should not have to do this, there's no reason other than laziness in design (or protecting dealership mechanics) why you shouldn't be able to access the back of the lamp shrouds by just lifting the hood.
