GM extending warranties on Cadillac CTS-V and Chevy Camaro ZL1 for supercharger issue

Okay General Motors, we've sat by and watched you recall the compact cars, crossovers and pickup trucks, and aside from reporting on it, we've been fairly quiet. This, though, this will not do. We can almost tolerate the recalls on the bread-and-butter cars, but leave the performance vehicles alone.
According to a report from The Car Connection, GM has discovered a problem with the superchargers of the 6.2-liter V8s found in the Chevrolet Camaro ZL1 and the Cadillac CTS-V. Apparently, the issue rests around the internal bearing shaft grease, which can become contaminated (we aren't sure with what). If left unchecked, it'll first lead to a rattle at idle, which goes away under slight throttle. The real warning stage is when a high-pitched squeal develops, signaling that the bearing shaft has failed. Naturally, severe engine damage is the next step (although it's possible that the engine will also just refuse to turnover, although neither case is desirable).
According to TCC, GM will replace the superchargers on vehicles that have exhibited symptoms of bearing shaft failure free of charge. It will also, allegedly, be extending the warranty on all supercharged ZL1s and CTS-Vs to 10 years or 120,000 miles (whichever comes first), from the date of purchase. Officially, only 2009 to 2013 CTS-Vs and 2012 to 2013 ZL1s are suffering from this issue.

Watch the 2019 Autoblog Technology of the Year presentation to Cadillac

Autoblog presented our 2019 Technology of the Year Award to Cadillac at the Detroit Auto Show. Autoblog conducted rigorous testing last fall on the latest automotive technologies, and Cadillac Super Cruise earned top honors, edging out Infiniti's Variable Compression Turbo and Mercedes' EQ technologies, the other two finalists. Super Cruise is a semi-autonomous system that allows for hands-free driving to reduce the driver's workload. Our editors found it easy to use and noted the system simply works as intended. We happily found Cadillac under-promised and over-delivered with Super Cruise, a clever system that truly helps the driver. Super Cruise launched on the CT6 sedan, and Cadillac plans to roll out the feature to other vehicles. Watch the video above as Cadillac President Steve Carlisle receives the 2019 Autoblog Technology of the Year Award from Editor-in-Chief Greg Migliore, with Autoblog GM Adam Morath and the editorial team on hand at the Detroit show.
