Power Steering Light On problems of the 2013 Chevrolet Equinox

My car made an aggressive right turn on its own. Back story: I started up my car and started slowly driving straight out of a street parking spot. I noticed the steering was slightly resisting me. I made a right turn and noticed the car was pulling some to the right (I actively had to counter it). About half way down the block my car made an aggressive right turn on its own (the steering wheel turned 90 degrees before I could fight it back and come to a stop from ~20mph). While stopped I turned the steering wheel all the way to the left, all the way to the right and back to center. I got out of the car and checked all tires. There was no flats or issues with the tires, tire pressure gages were reading normal. I started driving again and the car was still fighting me. Thinking it could be the banked road (but never has been an issue before), I turned right onto a flat street. The car still was trying to pull me to right on a flat street for about 2 blocks and then it eased up and drove normally again. Two days later the "service power steering" warning appeared for 30-60 seconds upon starting my car then disappears on its own. Steering problems has never been an issue before and has not happen again in the past 4 days with minimal driving. The warning to service power steering is not consistent upon starting my car and has never appeared prior to the car steering on its own.

On a cold winter day approximately 20 degrees, I exited off of the highway. Upon coming to a stop at the toll plaza, the car began making a horrible clanking noise, the �engine reduced power� notification appeared as well as the traction activation. The car died but started back up to get it off the road to safety. Had it towed to the nearest Chevrolet dealership and discovered the pcv system froze up and blew the rear main seal. The car had 103k miles on it at the time and was purchased new. Never had a single problem with it and always we'll maintained. Ended up having to replace the motor to the tune of $5,575. Less than 24 hours after picking it up from the dealership, it would not start. The stabilitrack and power steering lights came on and had to be towed back to the dealership.

Car would not start. Charged battery up car started. Inside controls would not work. Sommers dealership charged me $800. 00 to put a brand new blower motor in. Blower motor stopped working and now service power steering light comes on.
