GM recalls 61k more vehicles in three campaigns

Following a stop-delivery order for its new midsize trucks and a rash of recent recalls, General Motors is issuing three more campaigns covering 60,575 vehicles in North America with 57,182 of them in the US. As of October 1, the automaker has issued a total of 74 recalls (see the ridiculously long chart to the right) this year covering 26,495,070 units in the US.
The largest campaign covers 46,873 examples in the US of the 2008-2009 Pontiac G8 and 2011-2013 Chevrolet Caprice Police Patrol Vehicle imported from Australia. It's possible for the driver's knee to hit the key and make it move from the "Run" to "ACC" position while driving. GM says its Holden division is developing a fixed-blade key that's supposed to fix the problem by only allowing it to rotate toward the "On" position. There has been one crash caused by this fault but no injuries or fatalities.
The second recall is for 10,005 units of the 2004-2007 Cadillac CTS-V and 2006-2007 Cadillac STS-V because "the fuel pump module electrical terminal may overheat." This can cause a flange to melt and allow the pump to leak fuel. GM specifies that the remedy for the CTS-V is replacing the fuel module and fuel tank jumper harness, but it doesn't specify how the STS-V is being repaired.

Cadillac still planning for big things in China

Despite some hiccups, China remains the auto industry's great hope for new vehicle sales, with significant sales gains and a huge upside. Nowhere is that hope more fervent than at General Motors, which offers eight different marques in the Asian nation. China has been GM's single biggest market the last three years running, and is unlikely to give up that title anytime soon. Yet its premiere brand, Cadillac, has remained essentially stagnant, selling just 30,000 units in China last year. That's in a segment where sales of luxury vehicles has outpaced that of the larger Chinese market. So what gives?
According to Cadillac officials Autoblog spoke with in China this week at the Shanghai Motor Show, it's been a problem of product - they haven't had the right ones. Displacement taxation issues, import tariffs and currency fluctuations have all conspired to make the brand's products less appealing than they might otherwise have been. But GM is stepping on the gas with Cadillac, and executives are eyeballing 100,000 sales by 2016 - more than triple the Wreath and Crest's current volume. And the expectations for the brand only get more ambitious from there - they're shooting for 10 percent of the luxury market by 2020. Bob Socia, President of GM China, promises that there will be a new Caddy launched in the market each year from now through 2016 and most will be built in China. Characterizing the company's efforts to revive the brand's fortunes as a "relaunch" of sorts, Cadillac also figures to gain dealers as GM expands its sales outlet footprint westward.
New products like a made-in-China XTS sedan (with a market-specific 2.0-liter four-cylinder to avoid heavy displacement taxes) will help, and Socia hinted that the ATS sport sedan could be next in line for in-country production. The SRX crossover - currently the brand's best-selling model in China - will also likely get a long look for future local production when the next-generation model is introduced. In the meantime, Cadillac unveiled the Escalade ESV Hybrid (shown above) as its latest model addition to capitalize on the market's white-hot luxury SUV segment.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
