Hi Scotty. My name is Trace. I phoned a Hyundai dealership (not that I would have them do the work) about what they do on a 45,000 mile maintenance on my 2017 Hyundai Elantra with the naturally aspirated MPI 2.0 liter. They said that in addition to what is recommended in the owners manual, they flush out all the brake fluid and replace it because the ABS may stop working correctly if the fluid isn't replaced. They also do a fuel injector flush. SCAM ?
Thank you for your time and expertise.

the brake fluid and replace it because the ABS may stop working correctly if the fluid isn't replaced
False, the required brake fluid maintenance is written in your owners manual.
fuel injector flush
No need, these MPi injectors go for a very long while.
MPI 2.0 liter
G4NA engine? If so, replace engine oil more frequently these have a design flaw with scuffed cylinder bores only remedied on 2018-up.
It has the G4NH engine
Does anyone know if there any problems with that engine
Thanks
The G4NH is a fine engine, all it requires is for you to keep up with frequent oil changes. (5k-6k miles is best).
The only well known quirk on these are random check engine lights that are caused not by actual failures but by electrical glitches (so in case of a check engine light, diagnose, and check if the supposedly faulty part’s functionality before replacing) - Hyundai is trying to solve that with firmware.

If you have the G4NH with the A6 conventional 6 speed - then you won the Hyundai lottery.
one of the most solid drivetrains they made.
(Just remember to also keep up with tranny maintenance, 37.5k miles in between ATF replacements - it’s easy and cheap on these. And if maintained well I’ve seen these 6 speeds go 200k+)
Brake fluid flush is not a bad idea. I don't know if it would affect the ABS on that car but you'll have fewer hydraulic problems with clean fluid in the brake system and that car is 6 years old. (Brake fluid absorbs moisture over time.) Any good mechanic can do that service cheaper than the dealer. Flushing brake fluid may require a bidirectional scan tool though to deal with the ABS so it may not be doable at home for most people.
The fuel injector flush is a scam. Put some Techron in the tank if it's a concern.
The water content of brake-fluid -which is the main deteriorate aspect- (vapor bubbles which can cause loss of braking)- can be measured with a test-probe, but a.f.a.i.k. changing the fluid every 2 years was always recommended.
(Silicone brake fluids do not absorb water, but can/will harm rubber brake-components (seals a.s.o.) in older cars).
