General Motors has issued 30 recalls so far this year following a firestorm of backlash after it was found the company hesitated to recall certain small vehicles with faulty ignition switches. CEO Mary Barra is taking no chances and has fast tracked multiple recalls which may have been pending or just being looked into prior to the ignition switch debacle. Most of the cars recalled have been economy cars, pickup trucks or SUVs, but now some issues have arisen in the Camaro and CTS-V performance models as well.
The problem: The Car Connection reports the supercharger system in the 6.2-liter LSA V8 engine found under the hood of the Camaro ZL1 and Cadillac CTS-V may fail under certain conditions. The issue lies with the internal bearing shaft grease, which may become contaminated in one way or another. If not attended to, the bearing shaft grease may cause the supercharger to rattle at idle. It also may start to make a high-pitched squeal, which means the bearing shaft has failed. Eventually, the problem could result in total engine failure.
Number of vehicles affected: GM has remained mum on the issue so far and thus, an exact number of affected vehicles is not available. The Car Connection says only 2009 to 2013 CTS-Vs and 2012 to 2013 ZL1s are affected by the supercharger problem.
The fix: GM will replace the superchargers on LSA-powered vehicles at no cost. It will also be extending the warranty on all CTS-Vs and Camaro ZL1s to 10 years or 120,000 miles, however the lengthy warranty will be for the supercharger-related issue only.
