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's redesigned full-size 2021 SUVs face delay over coronavirus

As General Motors works to conserve cash for the coronavirus pandemic, the automaker reportedly told suppliers that it is postponing development of several future vehicles. The situation may cause GM to delay the launch of the 2021 Cadillac Escalade, GMC Yukon, Chevrolet Tahoe and Chevrolet Suburban SUVs, which had been planned to roll out in April. The original launch plan for the redesigned full-size SUVs, which are some of the most profitable vehicles produced by GM, had called for production of the current models to end at its plant in Arlington, Texas, this week. After a retooling process, the redesigned SUVs were slated to begin production late in the month of April. In an email to suppliers viewed by Reuters and confirmed as authentic by GM, the automaker also said it was suspending development work on six future vehicle programs, including updates of the Chevrolet Equinox, GMC Terrain, Cadillac XT4, Bolt EV, Chevrolet Silverado and GMC Sierra. GM said preproduction work on those programs would be pushed back to calendar year 2021, with most of the updated vehicles scheduled to be launched as 2022 models. According to the Detroit News, work has also been paused on the Chevy Camaro and a future version of the Corvette that has yet to be unveiled and wasn't planned for production during the 2020 calendar year. Last week, the automaker told employees and suppliers it was delaying work on some future vehicles while pushing ahead with near-term models such as its redesigned full-size SUVs and the GMC Hummer EV, Cadillac Lyriq, Chevrolet Bolt EUV and Cruise Origin, as well as its new Ultium battery system. A GM spokesman who spoke with Reuters reiterated on Monday what the automaker had said last week — that the situation with its U.S. plants was "fluid" and that the automaker would "continue to evaluate" whether and when to reopen those plants on a week-by-week basis, with "employee safety" guiding that decision. GM said previously that it was closing most of its U.S. plants indefinitely. In its Monday email, GM asked suppliers to stop work on all pre-production tooling and pre-production parts manufacturing, but also not to dispose of any tooling or materials. GM told Reuters it had solicited volunteers from its workforce to finish the build-out of the current SUVs on a single shift in Arlington.

Buy a Mosler Twinstar, the V16 Cadillac you almost wanted [w/video]

Cadillac was once famous for opulent, V16 luxury vehicles, but this bizarre 16-cylinder 1999 Eldorado that's for auction on eBay Motors isn't much like its ancestors. Dubbed the TwinStar, this beast features a Northstar V8 with 275 horsepower to drive the front wheels and a second Northstar with 300 hp is in the trunk to spin the rear axle. Each mill has its own four-speed automatic gearbox, and the result is a total of 575 hp of all-wheel drive fury in an incredibly weird package. The TwinStar's interior and exterior certainly don't hide the odd powertrain setup. To fit the engine in the trunk, the builders pushed the rear wheels further back and lengthened the wheelbase. There are also scoops low on each side to funnel air to the V8. Inside, there's a second ignition on the side of the center stack, and a digital instrument cluster replaces the glove box. It's sure to confuse any passenger you can convince to take a ride in this thing. Mosler, the supercar company known for models like the MT900, built five TwinStars, according to the auction. The seller links to the original review by Car and Driver, and the magazine noted that the sensation of the two engines working in tandem was rather odd. However, the TwinStar was a capable performer and ran to 60 in 5 seconds in its test. If you want to start your new year with the oddest vehicle possible, the TwinStar's auction sits at $5,600 with the reserve not met as of this writing, and it ends January 2, 2016, at 8:00 PM ET. If you can't wait that long, the dealer lists the car online for $39,900. There's also a spirited conversation on Bring a Trailer about this automotive oddity.
