Service column lock (scl) code on dic occurs with high frequency on 2005 Chevrolet Corvette MN06 when attempting to crank engine - car will not crank, other electrical components function. Car flatbed-towed on at least 4 occasions. Car was serviced numerous times, by 3 different Chevrolet dealers, for separate scl incidents occurring 2006-2010; most recent scl incidents occurred 6/2010 & 11/2010; car towed to Chevrolet dealer in 6/2010 to a Chevy dealer that claims to be Corvette service center of South. Dealer replaced scl part but only after the car experienced scl failure on their lot when I attempted to take delivery after they certified the car was fine. Car experienced scl on their lot and was pushed into service bay. Scl post-repair failure occurred 11/2010 following dealer's replacement/repair of scl part. Car towed to private auto repair shop where scl post-repair failure was discovered (hint: Tapping the column released the scl): BCM also required replacement - car would not communicate with bi-directional tool. Scl issue exists with many 2005 Corvettes (refer to Corvette forums); scl was a notorious problem for C5 production years -refer to NHTSA recall campaign number : 04V060000. GM issued scl recall for C5, but not yet for C6. Multiple C6 owners report experiencing scl failure & post-repair failure -- GM refuses to acknowledge this is a GM problem - owners are paying for the repairs and there is no guarantee that the new scl part will function and no guarantee that the steering column will not lock during operation. GM refuses to recognize that they have a serious safety and defective engineering issue with the 2005 C6 production model.
