Report: GM extending warranties on Cadillac CTS-V and Chevrolet Camaro ZL1 over supercharger troubles

Here’s one of the many reasons we can dock a tally of dislike on forced-induction–there’s just more to go wrong. And just as an unfortunate example, word is from The Car Connection that recent model Cadillac CTS-V and Chevrolet Camaro ZL1s are suffering some premature supercharger troubles.

As a result, GM is extending the warranties on both cars. The General’s engineers reportedly discovered a problem with the 6.2L LSA V8s, specifically with the internal bearing shaft lubrication system, which can become contaminated. If not checked or repaired, the supercharger will begin to rattle. This could then escalate into the failure of the supercharger in general as the internal bearing shaft loses its ability to stay lubricated leading to premature wear.

GM will replace the superchargers affected and already exhibiting these issues free of charge. The warranty itself is extended to 10 years and 120,000 miles, whichever comes first. Only 2009 to 2013 CTS-Vs are affected as well as 2012 and 2013 ZL1s.
