No error codes. it started as an intermittent issue. Now, I have no power steering. The steering wheel is not vibrating or pulling... where should I look? Thanks in advance for your advice!

It will need to be scanned to see what fault codes come up and go from there....

Did you happen to find your problem because I have a 2011 with the red steering wheel of death on the dash and no power steering it is currently the only vehicle I have to trust driving out of town for work and would love to know why I have no power steering my computer pulls up a code for the power steering control module, I have no clue where the module is located or anything of those lines, is it something I can replace or is it something that’s made into the whole rack assembly I have no ideas where I need to go from here, any advise would be greatly appreciated!!!

The usual fault is that the battery is not strong enough that when the engine is starting the voltage drops too low and flags a fault for the Electric Power Steering (EPS) and takes the steering offline.

Have the battery checked for condition and replace if necessary - this is the best place to start your diagnosis
