Hello, new to the forum just purchased a 2011 regal cxl for my wife to drive, great car so far but this morning she was driving to work, had to brake hard and the car went into some kind of "limp" mode for lack of better words. She said it was still running but lacked any power at all which left her stuck in traffic. She had to put car in park, shut off and restart then it ran fine the rest of the way for her. Car has 56,000 miles on it we are second owner from what I can tell and we bought extended warranty just in case which is bumper to bumper. Any input would be greatly appreciated.
