Steering Rack And Pinion problems of the 2012 Chevrolet Colorado

2012 chevy Colorado extended cab 2x4 i4 engine lt1. The problem is in the steering. The steering is extremely hard turning. The steering does not return to center at more than 30 degrease when after making a turn. When starting out, turn wheel 90 degrease and then proceed forward and the steering wheel will stay in this position and car will just drive in circles. Took to andrew chevy had sae certified tek test drive, stated there is a problem make an appointment. Andrew called and said it would need a new rack and pinion, replaced. Still all steering is the same. Took to heiser chevy they looked at it and the rack and pinion was leaking oil. Heiser replace rack and pinion still steering not fixed. Two days later power steering pump goes out. Heiser replaced power steering pump. Still remains with steering problem, does not return and really hard to steer. Like a tank. 900 miles, $23,000. 00 hmmmm. Chevy customer service useless telling me now that this is the way the truck is supposed to be. Not, owned a 2008 same model never had and issue like this and all good operating vehicle do not steer like this!!! when driving this truck be very aware and ready to return wheel "dangerous". Surely not what I learned in drivers ed, after making the turn let the wheel slide back threw your hands. 51 and some things you never forget. . .
