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.

GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.
Scroll down for the full list of GM's million 30+ mpg cars as well as an informative press release.

Cadillac goes white-out on social media as prelude to Oscars announcement [w/video]

Cadillac appears to be in a very odd place at the moment. On one hand, Johan De Nysschen is pushing the company towards a much more luxurious image that includes converting 700 dealers into boutiques, and a blitz of new products is also supposed to be on the way in the coming years. However, at the moment sales aren't necessarily keeping pace with production, and there are reportedly heavy incentives available on some models. Now, we're seeing the earliest hint at the next strike in the brand's strategy as its social media presence goes white across the web. Go check out Cadillac's official pages on the major social media hubs, and all you can find is blank space. There's just a period on Twitter, a blank box on Facebook, another one on Instagram and the company logo is even gone from Pinterest. Perhaps most bizarre is YouTube, where Caddy is showing five minutes of absolutely nothing (embedded below) with no sound at all. The video description is only a period. All of this nothingness is supposed to be a lead-up to Cadillac unveiling a completely new advertising campaign during the Oscars on February 22. This method of blanking everything out beforehand could suggest a minimal, to-the-point message in the future. While it wouldn't be shocking for a few teasers to come out in the meantime, Caddy is keeping quite a secret before the big reveal.
