GM reports that every single ZL1 and CTS-V is prone to develop the rattle

Owners of Camaro ZL1s and Cadillac CTS-V models are asked to return their rides to GM to have faulty superchargers swapped out for new, warrantied units.

GM announced that the 6.2L supercharged engines used in the 2012-2013 Camaro ZL1 and 2009-2013 Cadillac CTS-V were equipped with supercharger units that could begin to exhibit an unhealthy rattle. Owners will be able to tell if their supercharger is affected by the obvious rattle noise coming from under the hood. If left untreated, the rattle may lead to the contamination of the internal shaft bearing grease, which causes the bearing to squeal, overheat and ultimately seize the engine.

GM reports that every single ZL1 and CTS-V is prone to develop the rattle and is recommending that owners return their cars to the dealership to replace the supercharger and is waiving the $2095 fee for doing so. Owners affected will also receive a Special Coverage Adjustment. General Motors will extend the warranty of the supercharger for 10 years or 120,000 miles, whichever comes first.

Owners can contact GM at 1-800-458-8006 or contact their local Chevrolet or Cadillac dealer.
