I have no idea what is but that light is on and isndriving ceryvjerky, as well as coolant level low but coolant level is fine, so figure the coolant thing is just a sensor but very concerned about the restricted performance light. Anyone know? Also, the sunroof shadrs and sunnshade in back window buttons dint work. Someone please help me with advice as of course I bought it certified and am 10000 miles and a few months out of the certified warranty. Please someone tell me what it is and it’s not as bad as I think. What should I do?

 

were you driving it hard before light came on or normal driving? do you have supercharged engine?
