My 2010 CTS4 73000 mile .. I had it since a year and half . I had an issue yesterday while going to work.. the display said Electrical power reduced and then Tracktion control was on couldnt go beyond 20/30 MPH.. Question is after few hours the engine light was gone..is it a good thing to drive or take it to dealer and do you guys it covers under warranty since i surpassed 3000 miles beyond warranty of70000. Please let me know forum members any experience like that.
