Power steering failed while driving. being stuck in traffic i shut the car off and re-started it. the power steering came back. big problem or fluid issue?

This says it does have a fluid reservoir? Some electric power steering just has an electric pump as a opposed to a mechanical pump driven by the serpentine belt.

it s acceptable in full lock to lock turns to hear the humming with normal wight steering
and it is acceptable to drive the car without any power steering assist until have it fixed don`t be worry keep an eye on steering fluid

Just off the top of my head I would say that the fluid level is low and/or the pump is sucking air into the system and is dropping pressure pressure after a while.

YOU HAVE AIR IN THE POWER STEERING SYSTEM.YOU NEED TO BLEED POWER STEERING PUMP FIRST BEFORE DRIVING VECHICLE.CHECK POWER STEERING FLUID LEVEL ADD MORE POWER STEERING UNTIL REACH FULL COLD MARK..RAISE VECHICLE FRONT WHEELS OFF THE GROUND.START ENGINE LET IT IDLE WHILE TURNING STEERING WHEEL LEFT TO RIGHT NON STOP DONT LOCK OR STOP STEERING WHEEL KEEP TURNING IT SEVERAL TIMES CHECK POWER STEERING FLUID IF LOW ADD UNTIL YOU GET COLD MARK ON DIP STICK DONT OVER FILL POWER STEERING PUMP BLOW A SEAL.IF POWER STEERING FLUID LOOK TAN COLOR SYSTEM FULL OF AIR.TURN OFF IGNITION LET CAR SET FOR A WHILE CHECK FLUID LEVEL.IF STEERING WHEEL FEEL STIFF HARD TURNING DONT DRIVE CAR UNTIL YOU HAVE NORMAL STEERING.IF STILL HAVE AIR IN SYSTEM BLEED SYSTEM UNTIL AIR IS OUT.

SIPHON OUT POWER STEERING FLUID.USING A HAND PUMP SIPHON TYPE YOU BUY AT ANY AUTO PARTS STORES.PLACE DRAIN PAN UNDER CAR NEAR POWER STEERING PUMP CATCH FLUID WHEN YOU REMOVE POWER STEERING LINES AT THE PUMP.REMOVE DRIVE BELT.THEN REMOVE POWER STEERING PUMP.YOU NEED TO TAKE OLD PUMP WITH YOU.TAKE NEW PUMP AND OLD PUMP TO MACHINE SHOP THEY WILL REMOVE POWER STEERING PUMP PULLEY FROM THE OLD PUMP TRANSFER PULLEY TO THE NEW POWER STEERING PUMP YOU NEED TO BUY NEW POWER.STEERING HOSES O RINGS TO GO ON NEW POWER STEERING PUMP.HOSES THE OLD ORINGS WILL LEAK. THEN TAKE NEW POWER STEERING PUMP ON INSTALL IN VECHICLE THEN BLEED POWER STEERING SYSTEM.FILL POWER STEERING PUMP UP NEW FLUID.WAIT FEW MINUTES.WHEN LEVEL DROP ADD MORE FLUID UNTIL YOU GET TO FULL COLD MARK.START ENGINE 15 SECONDS SHUT OFF CHECK FOR LEAKS. NOW CHECK POWER STEERING AGAIN ADD TO FULL COLD MARK.NOW RAISE FRONT WHEELS OFF GROUND.START ENGINES TURN STEERING LEFT TO RIGHT WITH OUT STOPPING IT DO SEVERAL TIMES THEN CHECK FLUID.ADD TO THE COLD MARK DONT OVER FILL.IF FLUID LOOKS TAN HAS AIR BUBBLES IN SYSTEM WAIT A WHILE UNTIL FLUID SETTLE CHECK FLUID LEVEL.DONT DRIVE VECHICLE UNTIL STEERING FEELS NORMAL.AND IF YOU HEAR NOISES.LOCATE PROBLEM FIX BEFORE DRIVING VECHICLE.

Hmm.. Low fluid in the power steering pump, broken belt driving the power steering pump, failed component causing loss of power steering fluid, failed power steering pump.

Check for a broken belt first, check the oil in the pump, look for leakage under the truck.

If the pump is low on fluid you want to put about half the amount in that you're going to need and then start the truck and turn the wheel slowly from stop to stop, each way- spend about ten seconds going from one stop to the other. This will allow any air in the system to be purged out in a controlled fashion, it can really spray if you get a big, compressed bubble of air in the system and release it quickly. Shut the truck off and top the steering pump up, check for leaks.

It may be as simple as low on power steering fluid.

Well, I'm glad your O.K. You could have one of many problems going on, I would start with the simple, change your air filter. If you service your car regularly, thats probably not it, but ya never know, there could be something stuck in there. If that don't fix it, then there are many more things to look at, and you will probably want someone qualified to check it out for you, As I said before tho, It's definatly not dieing because of the steering fluid. Are there any smells when the car dies?

It is most likely you just turned the wheel to the farthest limit of its travel, and the power assist cutout at that point.

Check your fluid level to make sure its up to where it should be.

If fluid is fine, I wouldn't worry about it...it is fine and a normal occurance.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Check your power steering fluid level. Top it off with power steering fluid only.

The pump and or steering mechanism may be failing. Be very careful driving this vehicle as a full failure could leave you without any steering.
