Consumer Description

I keep getting this message that pops up, "Steering Assist reduced Drive with Care". At the same time this happens the temp gauge stays on cold, the ac quits working, the engine fan is on high, and most of the time I get code PO128. We have had it in to the dealer and they said the its the thermostat or the temp sensor. From what I am reading it could be a factory issue with the EMI issue from sensitive ECT circuitry. This has been an ongoing issue for us for over a year.
