general problems of the 2007 GMC Envoy

Just bought my used Envoy 7months ago and started pouring out power steering fluid. Got an estimate for 4 power steering lines and oil coller for a total of $1497 + tax. I've never had a vehicle that I had to add power steer fluid to. Seems like a dangerous situation.

I was driving my car and the wheel locked and my light service stability came on.

I got into the truck to leave work shifted into reversed half way thru the turn the wheel locked up and truck shut off. I put in park and restarted no problem the next day same thing at a red light wheel lock needs to be restarted. It sounds like the same issues on the recall but my truck is not on the list.

I had been driving for about ten minutes when the security light on my instrument panel came on. This is the light indicating the passlock system had initiated. My steering wheel locked up so that I could not turn it at all, and the car began decelerating quickly on its own.
