NAPA sells injector cleaner that works just fine..   I used it in my Camaro (190k miles) mu Mont Carlo, my F150 and my wife's DTS.    Just add it to your gas tank when you fill up.    This modern gas DOES tend to go bad pretty quickly, but I would run a couple of tanks full with the NAPA cleaner through it before I spent $200.....

45K should be nothing for the injectors. A can of Seafoam should clean out anything attached to the injector.

I clean my own injectors for far less than $200. Just pull them out and clean them by hand with carb/injector cleaner if it's worth it to you to go to that kind of trouble.

Is it currently running bad? or was she being told that a maintenance schedule needed to be followed?

I just put "Gumout" or similar  in the tank.   A mechanic friend recommended it , so...

I would ask the dealer where in the scheduled maintenance table it says to clean the injectors every 45k miles (nowhere)
I would ask it just to see what sort of elite level mental gymnastics he used to try to justify it, because unless you use Bob's Gas and let the car sit 6 months at a time there is no need to EVER have the injectors clean
Modern gas blends have cleaners built into them from the supplier (like Techron, one of the best fuel system cleaners available, in Chevron gas)
use quality gas and drive the car and there will never be a need to clean the injectors

And I have to agree with Stew, as an ex pro wrench, I was a favorite of the ladies because I never tried to soak them, was alway willing to explain not only what I was doing but WHY (including a basic lesson on how that system worked) and became visibly indignant when I was told of crap like this

Actually I became indignant when I heard this sort of crap run on anybody, because mechanics that do stuff like this are a bad reflection on ALL mechanics, and i don't need some jackass with a ASE patch who clearly knows better besmirching my reputation by assosiation

As cars have become more reliable, and the old tune up stuff (plugs, points, condenser, distributor cap) have either been eliminated or gone to extended replacement (spark plugs used to last 20,000 miles....now they can go well beyond 80,000 miles in some cars) - the Dealers are making up stuff to get you to come in and get work done.  On the VW my wife had as her last car......the scheduled maintenance they recommend would have required her to have her car in every 3 months for something.

Find an injector/fuel system cleaner, and put a bottle in a few times a year.....and/or buy name brand gas (Shell, BP, Sunoco, Chevron) if you can afford it, as they do have more additives than the economy brand fuels.

Thanks, she uses shell gas. ( I believe her car is 4 cylinders)I'll tell her it's optional for her to add gumout once or twice a year . I have seen a few negative comments about it in a forum , but I believe it can't really hurt at that rate. Thanks again!
