Trouble with my power steering

recently my power steering light will come on and I lose my power steering, I’ve already checked power steering level and it was ok,so what is wrong with my car?

Does this car have electric power steering. If so, I cannot comment other than recommend to see a mechanic versed in these systems, since most cars have hydraulic power steering. You may have to back to the dealer, or other GM dealer for this.

Since regular hydraulic systems don’t typically have a power steering light, I have to assume this is an electronic “steer by wire” system. As Doc suggested, these systems are relatively new to the market and you may need to find some shop versed in these or go back to the dealer.

Sorry, I’m not versed in these systems.
