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.

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.

GM's Cruise Origin EV platform to be shared by many electric vehicles

GM on Monday announced that it was spending $2.2 billion at its Detroit-Hamtramck facility, part of its $3 billion commitment made after the UAW strike to transform Hamtramck into the company's first plant to exclusively build a wide variety of electric and autonomous vehicles. The operation will eventually employ 2,225 people. Hamtramck is still building the Cadillac CT6 and Chevy Impala. Production of those cars will wind down Feb. 28, when GM will idle the lines for 18 months of retooling. During the transition, more than 800 workers will likely be transferred to build pickups at Fort Wayne, Indiana, or Flint, Michigan. When Hamtramck production of new EVs begins in late 2021, the Cruise Origin electric shuttle revealed last week will be among the first vehicles built there. Also, an electric pickup likely branded as a Hummer to be sold as a GMC, which will be debuted by LeBron James during the Super Bowl this Sunday. GM made quite a few pronouncements during the unveiling of the electric, autonomous Cruise Origin last week in San Francisco. We heard that the Origin was designed to last for for 1 million miles, be "roughly half the cost of what a conventional electric SUV costs today,” and riders could save as much as $5,000 per year by giving up their cars for Origins. Much was left out, as well, such as detailed specs on the platform, and when the Origin could see wide deployment. Carscoops addressed one open question about the platform, reporting that the Origin's bones will be shared among a number of other GM battery-electric vehicles, probably starting with the Cadillac EV due in 2021. The site received confirmation of that tidbit from Megan Soule, the automaker's assistant manager of Electrification, Battery Technology, Fuel Cells, R&D and GM Ventures Communications. It seems what we've been shown in the Origin is the first fruit of the multi-vehicle EV strategy GM CEO Marry Barra presented at the 2017 Barclays Global Automotive Conference. One of the slides (below, full PDF presentation here) touts an "All new multi-brand, multi-segment platform" with a "Structurally integrated all new battery system." The next slide places that modular platform at the center of 11 new vehicles, the van-looking silhouette on the upper right labeled "SAV," for shared autonomous vehicle, apparently in reference to the Origin.
