The vehicles fails to recognize it’s in park and does not shut off. Shift to park indicator turns on. Frequently have to park on incline and worried the vehicle will roll. The vehicle will not completely turn off and this has caused the steering to lock. When the vehicle finally turned off, then turned it back on we couldn’t get the steering wheel to unlock. Had to drive it with what felt like no power steering for a period of time. Shift to park indicator blinks and warning light appears that says no remote is detected, yet the remote is in the vehicle. Been in a situation where had to quickly get in to a Dr but the vehicle wouldn’t turn off so had to leave the vehicle running. At that point anything could happen, but had to take care of a sick child.

Power steering assist warning comes up. Becomes very doiccicult to steer and also caused stability control to be turned off. Extremely dangersous as my car could have rolled and killed me or my passengers. And appears to be a major issue, as what I have found online and manufactirer/dealer dont care. Please do something before people start dying/crashing because of this. 2nd concern - shifter......starts refysing to go into park. Eventually killing the battery. Switch is all messed up and alot of people have hte same issue an ddealer/manufactrurere refuse to do anything... They will fix it, at owners cost, for 700 bucks, which it only took me 30 minutes, not 2.5 hrs like they said.

Power steering failed on vehicle while in motion. Electric power steering module failed causing extreme difficulty getting the vehicle parked. Steering rack had to be replaced and computer re-programmed. Vehicle is back at the dealer with a similar trouble code for a follow up to the original repair. It took gm over 4 months to get the replacement part making us drive our vehicle with a faulty steering rack never once providing a loaner vehicle or buyback opportunity.

I was driving my car, straight, down our road at about 40 MPH when the car suddenly started to shudder, loose power and then then engine stalled (lost steering ability and engine propulsion). If this had happened at a busy intersection, while making a left hande turn, it could have been fatal.
