Does my car even have power steering fluid?

If it was built after roughly 2010 and there is no reservoir marked power steering in the engine bay, probably not — electric rack steering has no fluid, no flush, and no maintenance menu item. Five minutes with the owner's manual fluids page is the whole answer. Many cars being sold this service every week simply do not have the parts for it.

My hydraulic steering is low on fluid. Can I top it off?

You can top it off to get home, but the honest reading is that the system is sealed except at its joints — a low reservoir is a slow leak, not evaporation. The rack seals, the high-pressure line, or the pump shaft are already telling you something, and a bottle of stop-leak varnishes that confession into the seal pack instead of fixing the one $60 seal that named itself.

The power steering flush found a new market the day it became mostly unnecessary — most new cars have nothing to flush.

Electric power steering has no pump, no fluid, no lines — which means the flush that lives on every maintenance menu is a service for a component an increasing share of cars do not own. If your car does have hydraulic steering and it is on original fluid at 120,000 miles, a drain-and-fill may genuinely help a groaning pump. It should never be a surprise line item on a car that is 40,000 miles in.

Honest interval

Only if hydraulic — inspect

Cost when it IS due

$120–$200 two-bottle drain-and-fill on a genuine hydraulic car; $0 correctly quoted on an EPS car because there is no service to sell

What the schedule actually says

Most modern cars are electric (EPS) and have no interval because they have no fluid. Hydraulic racks that do exist: manufacturer severe-service schedules of 60k–100k are legitimate; the every-oil-change flush sticker is not.

The inspection that beats the calendar

First question is which system you own — an EPS rack is a motor on the steering column with nothing to check; hydraulic lives on a belt beside the alternator and leaves a reservoir cap. For hydraulic: fluid color at the cap, whine at full lock when cold, and groan over bumps name real wear before anyone touches a flush kit.

How this job gets oversold

The steering system service on a menu for a car whose steering assist is a $1,400 electric motor assembly with no serviceable fluid — and the low-fluid-we-topped-it-off note that hides a leaking rack, the one failure mode where a bottle of stop-leak is genuinely the worst decision available.

The measurement that settles it

Confirming the car even HAS hydraulic steering (it is on your belt list or it is not), then a full-lock whine and cold-start groan check, and a rack-and-line inspection if the level ever dropped. A level that dropped and you did not notice is a leak with a timeline, not a refill.
