GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.

GM says hybrid Corvette no laughing matter [w/poll]

When Mark Reuss was in LA recently, he sat down to have a few words with the scribes at the Los Angeles Times. When the issue of a hybrid Corvette came up, Reuss answered with "Don't laugh." The General Motors president is a complete fan of the possibility, calling it "attractive" and "really fun," believing it would improve GM expertise and that "people would love it."
Naturally, the president being supportive of an idea doesn't give indication that a hybrid Corvette is on the way. However, with supercars like the Porsche 918 Spyder and Ferrari LaFerrari giving hybrid tech a solid, if remote, place in the performance car world, the inexorable trickle-down of technology means we shouldn't be surprised if and when it does happen.
And now that we have that non-negative half-answer to a speculative question, it would be irresponsible for us not to commence rumormilling for the C8 Corvette. Taking Reuss at his word, the C8 will obviously be a hybrid with all-wheel-drive - the left side wheels driven with electric motors, the right side with the mid-mounted, four-cylinder diesel engine. With coefficient of drag of just .16, figure on a 0-to-60 mile-per-hour time of under 2 seconds and an all-electric range of something like 30 miles at top speed. Don't forget, folks, you read it here first.

GM says EVs are the future — but trucks are going to take it there

In the PowerPoint deck for the General Motors Capital Markets Day presentation, one of the more disturbing things comes early on, during GM President Mark Reuss' initial remarks, in an area where he is discussing the company's overall strength in trucks. The point being made is that GM has a truck for all and sundry. And there it is, a phrase on a slide that should send chills up the spines of those who still pine for the old Bob Seger "Like a Rock" Silverado ads: "Little bit country. Little bit rock 'n' roll." That's right. Donny and Marie. Somehow the Denis Leary snark in the F-150 ads is all the more appealing. The Capital Markets Day presentation was chock full of observations about electrification and automation (Reuss and CEO Mary Barra both noted that the corporation's vision is one of "Zero Crashes. Zero Emissions. Zero Congestion." Dan Ammann talked about the progress being made at Cruise Automation; Reuss rolled out the plan for an array of electrified vehicles, with a luxury EV and a compact SUV being the "Centroid Entries" for the modular bases of many others). But it is worth noting that there is no getting away from the power of pickups in the U.S. market, as that was the central topic in Chief Financial Officer Dhivya Suryadevara's comments, with "Truck Franchise" being flanked by "Key Financial Priorities" and "Financial Outlook." Clearly, to gloss the old phrase, the truck segment is where the money is. Suryadevra enumerated how the truck segment is significantly different than other types of light vehicles. Among her points: GM, Ford and FCA have more than 90% of market share. The truck parc has been growing and aging over the past 10 years. Customers are fiercely loyal to the segment—as in 70% of truck buyers are truck buyers. A good number of the vehicles are for commercial use (40 percent). Trucks are "less prone to. . .mobility disruption." Trucks offer high margins. Translaton: The segment is one that they're solidly positioned in. There are lots of old trucks on the road that will need to be replaced by new ones. Perhaps buyers may switch from a Sierra to a Canyon, but it will be a truck. If your livelihood depends on that type of vehicle, even if gas prices go up or the economy begins to go south, you're going to stick with it. Most of the country isn't San Francisco, so trucks will continue to be essential. And, well, they're profitable in the extreme.
