I have recently purchased an '03 cts luxery/sport package 3.2L engine. The car runs beautiful however my ABS and T/C lights constantly come on everytime i attempt to turn my sterring wheel. In some cases it will stay off but for the most part it eventually come on. The 2nd problem i have is that when i use my brakes i will sometimes hear a screatch that sound s like metal is touching medal somewhere. My brakes pads are perfect and so are my rotters so i know this is not the problem with this. The screatching sounds seems to present itself more often when it is wet outside (ie snow or rain). Is there anyone out there that can help me out with this problem?
