WELCOME to our forum, there f.james -
Does your car show you any codes (lights)?
First off, I'd suggest you check the air pressure in your front tires.
Next, check under the front end of the car and make sure nothing is binding the steering.
Then, I would suggest you check the fuse that controls the power steering mechanism.
If all looks OK, it might be time to take er into the shop.
Others will be along shortly with some more help.
