J.D. Power customer survey of dealers counts Cadillac, Buick as big winners

Cadillac and Buick have taken the trophies in J.D. Power's latest Customer Service Index Study examining satisfaction with dealer service. Surveying more than 90,000 owners and lessees of 2009-2013 model-year cars, the study found that those with pre-paid maintenance packages were ten percent more likely to buy their next car from the same brand.
Dealer satisfaction scores have improved overall, Cadillac nabbed the luxury segment ahead of Audi and Lexus, taking the crown that Lexus held last year. Buick keeps the mass-market dealer satisfaction win in the family, finishing ahead of Volkswagen and last year's winner GMC. The study also found that service department use of tablets increased customer satisfaction, as did "best practices" like "providing helpful advice." Who knew?
You can find details on those and more findings in the press release below.

Cadillac ATS-V shares track time and new face with CTS-V sibling

It's been about eight months since we last heard anything on the eagerly anticipated Cadillac ATS-V, meaning it was high time a new batch of photos arrived of the twin-turbocharged, V6-powered sedan.
This latest round includes a shot of the hot ATS-V alongside the upcoming CTS-V, allowing us to glimpse through the camouflage and spot the family resemblance between the two über sedans. According to our spies, this is the first time we've gotten a look at the ATS-V's fascia without a nose bra to obscure larger details. This isn't the first time we've seen a vertically slated grille on an in-development Cadillac V car, although it is the first time we've seen it on the ATS-V. Aside from the main grille, the shapes of the sportier front fascia of the ATS-V tie in nicely with its big brother. We are rather curious about the hood on the ATS-V. It's difficult to tell from these images, but it looks like there may be some vents up there that may be meant to improve cooling to the alleged 425-horsepower engine.
Other details that we can see include swollen fenders and larger wheels that hide amplified brakes. The rear of the car remains heavily obscured by camo, with the sole details of note being the quad exhausts, which we've spotted on previous ATS-V prototypes.

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.
