General Motors has discovered a problem with the supercharged 6.2-liter LSA V-8s fitted to certain versions of the Cadillac CTS-V and Chevrolet Camaro ZL1. The affected models are all 2009-2013 CTS-Vs and all 2012-2013 Camaro ZL1s.

According to the automaker, the engine's supercharger may not be functioning properly, causing the unit to develop a noticeable rattle noise at idle. The noise will normally go away when the engine revs start to rise, but the problem, if left unresolved, may lead to contamination of the internal shaft bearing grease and cause the bearing to squeal over time. This could lead to the bearing overheating, which in turn could cause the engine to seize or simply fail to start.

General Motors Company [NYSE:GM] dealers will replace the supercharger at no charge. As The Car Connection points out, this is a significant savings considering the fact that the supercharger alone is $2,095 and labor runs anywhere from 5 to 7.5 hours to do the job, according to GM's parts & labor guide.

Owners also receive a Special Coverage Adjustment for the problem. This special coverage covers the condition described above for a period of 10 years or 120,000 miles, whichever occurs first, from the date the vehicle is sent in to receive the new supercharger, regardless of ownership.
