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.

Cadillac CTS-V gets Stealth Blue and Silver Frost limited edition models

A little more than a year and a half ago, former weekend editor Alex Nunez and I were talking about how sweet it would be for Cadillac to offer a CTS-V in the Corvette's Supersonic Blue paint, and as if General Motors eavesdropped on our conversation, this showed up. And while the Stealth Blue car you see here isn't an exact duplicate of the hot-looking sedan GM showed off in prototype form, it's really close. And really sweet.
New for 2013, the Cadillac CTS range gets two new colorful editions, starting with the Stealth Blue package available on the CTS-V (in sedan, coupe and wagon bodystyles) as well as the naturally aspirated CTS coupe. In addition to the unique paint, blacked-out grille and dark satin wheels, Stealth Blue cars can also be done up with an optional Twilight Blue leather interior. (And you thought blue-on-blue color schemes died in the '90s.)
Cadillac is also offering a new Silver Frost package, but it's a bit more exclusive. Only 100 examples will be built, all in CTS-V Coupe form. The Silver Frost paint is a low-gloss matte finish, in that while it technically has a clearcoat covering, it's reduced in a way that the surface still appears flatter than standard paint. Even so, Cadillac states that the car should be hand-washed only.

GM CEO Akerson calls out Tesla, says Cadillac will compete on EVs

Cadillac will be taking on Tesla Motors, the underdog EV manufacturer that's seen heaps of critical acclaim and stock market buzz with its most recent sedan, the Model S. "If you want to compete head-to-head with Tesla, and we ultimately will, you want to do it with a Cadillac," Dan Akerson, the chairman and CEO of General Motors, told media in Washington, according to The Detroit News.
Akerson continued, telling The News, "We'll sell more Volts and lose less money on the Volts than they'll lose on the Model S." He also took time to point out that Tesla getting vehicles out to customers isn't a guarantee of success or permanence, using Fisker as an example, saying "Does anybody even remember Fisker? I mean, there were a number of them; they are all gone."
This strong talk from Akerson comes after Doug Parks, another GM exec, let slip that the Detroit-based manufacturer has an EV in the works that will cover 200 miles per charge and only cost about $30,000, a massive upgrade over similarly priced EVs that struggle to top 100 miles per charge. Until that vehicle arrives, though, GM is preparing the Cadillac ELR, a small coupe that, like the Volt with which it shares technology, uses a gas engine as a mobile generator to recharge the batteries. Akerson took aim at Tesla again, saying, "But I do think when the ELR comes out late this year, early next - it's certainly the same postal code as Tesla, but now we're going to move up. It's not going to be a mass-produced car."
