Bought a new 2017 Silverado 2500 6.0L and service power steering came across dash. Took to dealer and they said had to replace power steering control module. Changed then they said it wasn't communicating with steering box and had to replace that. Changed that then said steering module wasn't working and had to change that again. Changed and still not working. Also having infotainment issue and they said it was related and had to check wiring harness. They also found a coolant leak while messing with steering issue. Truck has 800 miles and been at the dealership a week now. Anyone else having these issues? Going to try to get them to buy back.
