GM Extends Supercharger Warranty On Chevy Camaro, Cadillac CTS-V

June 3, 2014

GM has found a problem with its supercharged 6.2 liter V-8s, ones fitted into the Chevy Camaro and Cadillac CTS-V.

On affected vehicles, the supercharger may not perform as designed, resulting in contamination of the unit's internal bearing shaft grease. When the problem is present, a rattle can be heard emanating from the engine at idle; slight acceleration above idle will cause it to go away.

If left uncorrected, contamination of the internal shaft bearing grease will accelerate into bearing failure, resulting in a loud squeal, then possible catastrophic engine damage or a no-start condition.

The fix

On affected vehicles, GM dealers will replace the supercharger at no charge. 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.

Warranty coverage and eligibility

GM is extending the warranty coverage on these vehicles for this problem to 10 years or 120,000 miles, whichever comes first from the original vehicle-in-service-date.

Vehicles covered in this action are the 2009-2013 Cadillac CTS-V and the 2012-2013 Chevy Camaro, both equipped with the 6.2-liter supercharged engines.

Call your local dealers with your VIN (Vehicle Identification Number) to determine your vehicle's eligibility to receive this service at no charge from GM.
