U1041???? Haven't heard of that one before. My manual lists B, C, and P codes but no U codes. The last time I had a no start condition with my cc it was cap/rotor problem. They were near new but obviously shorting out cylinder to cylinder as the engine acted like the cap was wet and cross-firing. Replaced both with AC Delco and no problems since.
