Sir, rep point for you, if you're within 200 miles of Los Angeles, I'll buy you a beer, because that's gotta be one of the best replies
What I was saying about the requirements for loaners/rentals is that in the warranty details it says that Nissan will pay up to $35/day (might be $30) for up to 3 days. And if the repair takes longer than 3 days that there needs to be a special request put into Nissan Corporate.
So it IS written in stone that you can/should get a loaner/rental (at least if you own a 370Z, Maxima, GTR, not sure if Nissan's warranty is the same for all their cars)
As redline said, their loaners are always used and reserved a week in advance, so all you need to do is call your dealer in advance, and just ask.
I was going to take my car in for some "problems" it has, called on a Thursday, and the dealer said they were out of loaners and the Enterprise they do business with only has the luxury whatevers so it would cost me $70/day...
No thank you, I'll schedule an appointment another time, LOL. There is no real need to complain, I SHOULD have called earlier, I just didn't know how packed my dealer here got over the weekends.
Now, god bless the '09s for having problems, if my car had steering lock failure, had it towed and they said they don't have loaners, I get my size 15 shoes primed for putting it up someone's ***... And even if they only had the luxury thing, you gotta wheel and deal a bit, you KNOW they're going to make money no matter what, tell them that, tell them they are welcome to warranty out anything else they want to help them make money... If your dealer is smart enough... Or shady enough, they'll do it, LOL!!!
If all that fails, yep, THAT'S when I'll START getting pissed off, and my preprimed shoe starts kicking ***... I'll tell the dealer that if they don't get me a rental within an hour (I think that's reasonable) that the call to corporate will be made, shítty Internet reviews, the lot. See the response, they still don't get you a car, walk outside, smoke a cigarette, call corporate, ask for the Ombudsman (and please guys, this is for BIG jobs, oil change, brake pad change, don't get pissed)
